WalkthroughThis commit integrates a broad set of changes across the repository. It adds new CI steps in several GitHub Actions workflows to set up CocoaPods, upgrades dependencies in the podspec, and introduces extensive CoinJoin functionality. Many model, manager, and transaction classes have been enhanced or newly created to support CoinJoin operations, including new FFI methods, message classes, and wallet/address handling methods. UI components and storyboard files have also been updated to introduce a new CoinJoin view controller, while several test plans have been modified to skip specific CoinJoin session tests. Additionally, transaction serialization methods now support an extra “anyoneCanPay” parameter. Changes

135-143: 💡 Verification agent🧩 Analysis chain
Method signature correctly updated for CoinJoin compatibility
The
toDataWithSubscriptIndex:anyoneCanPay:method implementation has been updated to include the newanyoneCanPayparameter, which is correctly passed to the superclass method.It would be beneficial to verify that all classes that call this method have been updated to use the new signature:
🏁 Script executed:
#!/bin/bash # Find all invocations of toDataWithSubscriptIndex: that might need updating rg -A 2 "toDataWithSubscriptIndex:" --glob "*.m" | grep -v "anyoneCanPay"Length of output: 5479
Action Required: Update Call Sites to Include the
anyoneCanPayParameterThe
DSQuorumCommitmentTransactionimplementation now correctly uses the updated method signature for CoinJoin compatibility by passing theanyoneCanPayparameter to the superclass. However, verification with the provided shell script shows that several other transaction classes still call the legacy version oftoDataWithSubscriptIndex:without the new parameter. For example:
- DashSync/shared/Models/Transactions/Coinbase/DSCoinbaseTransaction.m
- DashSync/shared/Models/Transactions/Provider/DSProviderRegistrationTransaction.m
- DashSync/shared/Models/Transactions/Provider/DSProviderUpdateRegistrarTransaction.m
- DashSync/shared/Models/Transactions/Provider/DSProviderUpdateRevocationTransaction.m
- DashSync/shared/Models/Transactions/Provider/DSProviderUpdateServiceTransaction.m
- DashSync/shared/Models/Transactions/Base/DSAssetUnlockTransaction.m
- DashSync/shared/Models/Transactions/Base/DSAssetLockTransaction.m
Please review these call sites and update them to include the
anyoneCanPayargument as required, or provide a rationale if the legacy signature should be maintained.

DashSync/shared/Models/Entities/DSFriendRequestEntity+CoreDataClass.m (1)
91-91: Clarify the TODO CommentThe added TODO comment (
// TODO: MOCK_DASHPAY mixed only?) is ambiguous. Please clarify the intent behind this comment—whether it indicates a temporary workaround, a pending feature flag for "MOCK_DASHPAY," or something else. A more descriptive comment will help future maintainers understand when and how to address this placeholder.Example/Tests/WalletTests.xctestplan (1)
26-26: Consider documenting rationale for skipped testsThe
DSCoinJoinSessionTestis being systematically skipped across all test plans, including this one.Consider adding a comment in the test file or documentation explaining why this test is skipped and under what conditions it should be re-enabled. This would help maintain testing quality in the future.
Example/Tests/TransactionTests.xctestplan (1)
26-26: Ensure test coverage through alternative meansWhile skipping
DSCoinJoinSessionTestin all test plans may help resolve CI issues, it's important to ensure the CoinJoin functionality is tested through other means.Since the CoinJoin feature appears to be a significant addition, I'd recommend creating a separate test plan specifically for CoinJoin tests that can be run manually or in a controlled environment if automated CI is problematic. Would you like me to provide a template for such a test plan?
Example/Tests/PlatformTransitionTests.xctestplan (1)
26-26: Consider documenting why DSCoinJoinSessionTest is being skippedI see that DSCoinJoinSessionTest has been added to the skipped tests array. While this might be necessary to resolve CI errors as mentioned in the PR description, it would be helpful to add a comment or documentation explaining why this test is being skipped and whether there's a plan to enable it in the future.
Would you like me to suggest a format for documenting skipped tests in your test plans?
DashSync/shared/Models/Messages/CoinJoin/DSSendCoinJoinQueue.h (1)
22-28: Clean implementation of DSSendCoinJoinQueue class.The class interface is minimal and follows good encapsulation principles with the read-only property. Consider adding documentation comments to explain the purpose of this class and what the
sendproperty represents in the context of CoinJoin operations.@interface DSSendCoinJoinQueue : DSMessageRequest +/** + * Boolean indicating whether to send CoinJoin queue messages to peers. + */ @property (nonatomic, readonly) BOOL send; +/** + * Creates a new request with the specified send flag. + * @param shouldSend Whether to send CoinJoin queue messages. + * @return A new DSSendCoinJoinQueue instance. + */ + (instancetype)requestWithShouldSend:(BOOL)shouldSend; @endDashSync/shared/Models/CoinJoin/DSTransactionOutput+CoinJoin.h (1)
26-27: Looks good, but consider documenting memory management patternThe FFI memory management methods are well-defined, following the malloc/free pattern. However, adding documentation comments would help clarify:
- When these methods should be used
- Who is responsible for calling
ffi_free- What the
ChainTypeparameter affectsConsider adding documentation comments like:
/** * Creates a TransactionOutput FFI object from this Objective-C instance. * @param type Chain type to use for serialization * @return Pointer to FFI struct that must be freed with ffi_free */ - (TransactionOutput *)ffi_malloc:(ChainType)type; /** * Frees memory allocated for a TransactionOutput FFI object. * @param output Pointer to FFI struct to free */ + (void)ffi_free:(TransactionOutput *)output;Example/DashSync/DSActionsViewController.m (1)

❓ Verification inconclusive
Fix typo in the segue identifier: "CoinJoinSeque" should be "CoinJoinSegue"
There's a spelling error in the segue identifier. While this will work as long as the identifier in the storyboard has the same typo, it's better to correct it for consistency.
- } else if ([segue.identifier isEqualToString:@"CoinJoinSeque"]) { + } else if ([segue.identifier isEqualToString:@"CoinJoinSegue"]) {
🏁 Script executed:
#!/bin/bash # Check if there's a storyboard file with the same typo or the correct spelling echo "Searching for storyboard files with CoinJoin segue..." rg -l "CoinJoinSeque" --type=xml rg -l "CoinJoinSegue" --type=xmlLength of output: 182
Action: Verify the CoinJoin segue identifier is consistent both in code and your storyboard.
The code in
Example/DashSync/DSActionsViewController.mcurrently checks for@"CoinJoinSeque", which appears to be a typo. The proposed change is to update the identifier to@"CoinJoinSegue". However, our automated search in XML files did not return any references for either string, making it unclear if the storyboard segue identifier needs the same correction. Please manually verify that the storyboard is configured with the proper identifier (CoinJoinSegue) to ensure consistency and avoid runtime mismatches.

23-29: Add documentation comments and consider implementing a common base class for CoinJoin messagesThe implementation looks good, but I notice that
DSCoinJoinEntryMessageandDSCoinJoinAcceptMessagehave identical interfaces. This suggests potential code duplication in their implementations.Consider:
- Adding documentation comments to explain the purpose of this message type:
/** * Represents a CoinJoin entry message sent during the initial phase of a CoinJoin session. * Contains serialized data related to the CoinJoin entry proposal. */
- Creating a common base class for CoinJoin message types to reduce duplication:
/** * Base class for CoinJoin-specific message types. */ @interface DSCoinJoinBaseMessage : DSMessageRequest @property (nonatomic, readonly) NSData *data; + (instancetype)requestWithData:(NSData *)data; @endThen have
DSCoinJoinEntryMessageand other similar classes inherit from this base class, only needing to implement the+typemethod.DashSync/shared/Libraries/Logs/CompressingLogFileManager.h (1)
1-20: Overall implementation looks good, consider adding documentationThe
CompressingLogFileManagerclass is properly designed as a subclass ofDDLogFileManagerDefaultwith appropriate properties and initialization method. This will help manage log file sizes through compression.Consider adding class and property documentation comments to explain:
- The purpose of this class (compressing log files when they reach a certain size)
- The role of the
upToDateandisCompressinginstance variables- How the
maxFileSizeproperty affects compression behaviorExample documentation:
+/** + * A log file manager that automatically compresses log files when they reach a specified size. + * Extends DDLogFileManagerDefault with compression capabilities. + */ @interface CompressingLogFileManager : DDLogFileManagerDefault { + // Tracks whether all files have been processed for compression BOOL upToDate; + // Flag indicating if compression is currently in progress BOOL isCompressing; } +/** + * The maximum size (in bytes) a log file can reach before being compressed. + */ @property (nonatomic, assign) unsigned long long maxFileSize;DashSync/shared/Models/Messages/CoinJoin/DSCoinJoinSignedInputs.h (1)
1-32: Implementation looks good, consider adding parameter documentationThe
DSCoinJoinSignedInputsclass is well-structured as a subclass ofDSMessageRequestwith appropriate properties and methods for the CoinJoin feature. The use ofNS_ASSUME_NONNULL_BEGIN/ENDfor nullability annotations is correct.Consider adding documentation comments for the class and methods to explain:
+/** + * Represents signed inputs for a CoinJoin transaction. + * Used to communicate input signatures between participants in a CoinJoin session. + */ @interface DSCoinJoinSignedInputs : DSMessageRequest @property (nonatomic, readonly) NSData *data; +/** + * Creates a request with the provided signed input data. + * @param data The signed input data for the CoinJoin transaction. + * @return A new DSCoinJoinSignedInputs instance. + */ + (instancetype)requestWithData:(NSData *)data; +/** + * Returns the message type string identifier. + * @return The string representing this message type. + */ + (NSString *)type;DashSync/shared/Models/Managers/Chain Managers/DSMasternodeManager.h (1)
71-71: Good API extension, but consider updating related methodAdding a method to retrieve the full masternode entry object rather than just checking for its existence is a useful enhancement that provides more detailed information.
Since you've added this new method, consider updating the existing
hasMasternodeAtLocation:port:method to use your new implementation for consistency:- (DSSimplifiedMasternodeEntry *)masternodeAtLocation:(UInt128)IPAddress port:(uint32_t)port; - (BOOL)hasMasternodeAtLocation:(UInt128)IPAddress port:(uint32_t)port;In the implementation file (.m), you could update the existing method like:
- (BOOL)hasMasternodeAtLocation:(UInt128)IPAddress port:(uint32_t)port { return [self masternodeAtLocation:IPAddress port:port] != nil; }This would reduce code duplication and ensure both methods use the same logic for finding masternodes.
DashSync/shared/Models/Derivation Paths/DSFundsDerivationPath.h (1)
57-57: Method looks good - consider adding documentation.The new method for creating CoinJoin derivation paths follows the pattern of existing derivation path methods. However, consider adding documentation comments to describe the purpose and behavior of this method, similar to other public API methods in the file.
+/** + * Creates a derivation path specifically for CoinJoin transactions. + * @param accountNumber The account number to use for the derivation path. + * @param chain The chain on which the derivation path will be used. + * @return A new CoinJoin derivation path instance. + */ + (instancetype)coinJoinDerivationPathForAccountNumber:(uint32_t)accountNumber onChain:(DSChain *)chain;DashSync/shared/Models/CoinJoin/DSTransactionInput+CoinJoin.h (2)
18-20: Import statement ordering could be improved.The imports are clear but could follow a more conventional ordering pattern: Foundation frameworks first, followed by third-party imports, and finally project-specific imports.
-#import "DSTransactionInput.h" -#import "dash_shared_core.h" -#import <Foundation/Foundation.h> +#import <Foundation/Foundation.h> +#import "dash_shared_core.h" +#import "DSTransactionInput.h"
26-27: Method signature inconsistency between instance and class methods.The file defines both an instance method
ffi_mallocand a class methodffi_free:. This is inconsistent and could lead to confusion. Either both should be instance methods or both should be class methods.-// Current inconsistent implementation -@interface DSTransactionInput (CoinJoin) - -- (TransactionInput *)ffi_malloc; -+ (void)ffi_free:(TransactionInput *)input; - -@end +// Option 1: Both as instance methods +@interface DSTransactionInput (CoinJoin) + +- (TransactionInput *)ffi_malloc; +- (void)ffi_free:(TransactionInput *)input; + +@end +// Option 2: Both as class methods (preferred for memory management) +@interface DSTransactionInput (CoinJoin) + ++ (TransactionInput *)ffi_malloc:(DSTransactionInput *)input; ++ (void)ffi_free:(TransactionInput *)input; + +@endDashSync/shared/Models/Managers/Chain Managers/DSPeerManager.h (2)
78-78: Property naming could be more descriptive.The property name
shouldSendDsqis somewhat cryptic. Consider using a more descriptive name likeshouldSendCoinJoinRequeststo better communicate its purpose, especially for developers not familiar with the "dsq" abbreviation (which likely stands for "DarkSend Queue").-@property (nonatomic, readonly) BOOL shouldSendDsq; +@property (nonatomic, readonly) BOOL shouldSendCoinJoinRequests;
96-99: Method naming could be more consistent with property naming.The method
shouldSendDsq:is a setter for theshouldSendDsqproperty. Consider renaming it to follow Objective-C's setter convention, such assetShouldSendDsq:. Also, consider adding documentation to explain the purpose of this method.// MARK: CoinJoin -// No documentation -- (void)shouldSendDsq:(BOOL)shouldSendDsq; +/** + * Sets whether CoinJoin queue requests should be sent to connected peers. + * @param shouldSendDsq If YES, CoinJoin queue requests will be sent to peers. + */ +- (void)setShouldSendDsq:(BOOL)shouldSendDsq;DashSync/shared/Models/CoinJoin/DSTransactionInput+CoinJoin.m (1)
1-58: Ensure proper documentation for FFI methodsWhile the code is well-structured, consider adding method documentation that explains the purpose of these FFI methods and how they're used in the CoinJoin process. This would help other developers understand the memory management requirements when working with these methods.
+/** + * Allocates and initializes a C-compatible TransactionInput structure from this Objective-C object. + * Caller is responsible for freeing the returned structure using +ffi_free:. + * @return A pointer to a newly allocated TransactionInput structure + */ - (TransactionInput *)ffi_malloc {+/** + * Frees memory allocated for a TransactionInput structure and its fields. + * @param input Pointer to the TransactionInput structure to free + */ + (void)ffi_free:(TransactionInput *)input {DashSync/shared/Models/CoinJoin/DSCompactTallyItem.h (1)
29-30: Inconsistent method declaration styleThere's a mismatch in method declaration styles:
ffi_malloc:is an instance method whileffi_free:is a class method. This is inconsistent with the pattern established in DSTransactionInput+CoinJoin where both malloc and free are class methods.- - (CompactTallyItem *)ffi_malloc:(ChainType)type; + + (CompactTallyItem *)ffi_malloc:(ChainType)type forItem:(DSCompactTallyItem *)item;Or alternatively, if the instance method approach is preferred:
- + (void)ffi_free:(CompactTallyItem *)item; + - (void)ffi_free:(CompactTallyItem *)item;Choose a consistent pattern across related classes to maintain code readability.
DashSync/shared/Models/Transactions/Coinbase/DSCoinbaseTransaction.m (1)
104-112: Consider updating method documentationThe method documentation comments should be updated to include information about the new anyoneCanPay parameter and its purpose in the context of CoinJoin transactions.
// Returns the binary transaction data that needs to be hashed and signed with the private key for the tx input at // subscriptIndex. A subscriptIndex of NSNotFound will return the entire signed transaction. +// The anyoneCanPay parameter determines if other inputs can be added to the transaction without invalidating +// existing signatures, which is essential for CoinJoin transactions. - (NSData *)toDataWithSubscriptIndex:(NSUInteger)subscriptIndex anyoneCanPay:(BOOL)anyoneCanPay {Example/DashSync/DSCoinJoinViewController.h (1)
1-32: LGTM: Header file looks well-structured.The new DSCoinJoinViewController header file is properly structured with appropriate properties for managing CoinJoin functionality in the UI. The class contains all necessary components to interface with the CoinJoin manager and present relevant UI controls to the user.
Consider adding brief documentation comments to explain the purpose of this class and its properties to improve code maintainability for other developers.
DashSync/shared/Models/CoinJoin/DSInputCoin.h (1)
25-36: Improve documentation for better understanding of the class.This class seems to be a critical part of the CoinJoin implementation, but lacks documentation explaining its purpose and usage.
Consider adding class-level documentation and method comments, especially for the FFI methods that interface with non-Objective-C code. This would help other developers understand:
- The purpose of this class in the CoinJoin workflow
- How the FFI methods should be used
- Memory management expectations for the foreign types
DashSync/shared/Models/CoinJoin/Utils/DSBackoff.m (1)
20-43: Consider adding thread safety for shared usage.This utility class might be accessed from multiple threads if CoinJoin operations run concurrently, but it lacks any thread safety mechanisms.
Consider adding thread safety using dispatch queues or locks when accessing shared properties like
_backoffand_retryTime.DashSync/shared/Models/CoinJoin/DSTransaction+CoinJoin.h (1)
24-31: Consider refining method naming and adding documentationThe category methods could benefit from clearer naming and documentation:
The
initWithTransaction:onChain:method doesn't follow Objective-C initializer conventions - initializers typically returninstancetype, not a specific type likeDSTransaction *. This looks more like a conversion method than a true initializer.All three methods lack documentation explaining their purpose, parameters, and return values, which would be helpful for other developers.
Consider:
- Renaming the first method to better reflect its purpose (e.g.,
transactionWithFFITransaction:onChain:)- Adding documentation comments for all three methods explaining their purpose in the FFI bridge
@interface DSTransaction (CoinJoin) - - (DSTransaction *)initWithTransaction:(Transaction *)transaction onChain:(DSChain *)chain; + /** + * Creates a DSTransaction instance from a C Transaction struct. + * @param transaction The C Transaction struct. + * @param chain The blockchain the transaction belongs to. + * @return A new DSTransaction instance. + */ + - (DSTransaction *)transactionWithFFITransaction:(Transaction *)transaction onChain:(DSChain *)chain; + /** + * Allocates memory for a C Transaction struct. + * @param chainType The type of blockchain. + * @return A pointer to the allocated Transaction struct. + */ - (Transaction *)ffi_malloc:(ChainType)chainType; + + /** + * Frees memory allocated for a C Transaction struct. + * @param tx The Transaction struct to free. + */ + (void)ffi_free:(Transaction *)tx;DashSync/shared/Models/Messages/CoinJoin/DSCoinJoinSignedInputs.m (2)
22-47: Implementation looks clean but could use documentationThe
DSCoinJoinSignedInputsimplementation is straightforward and follows standard Objective-C patterns.Consider adding documentation to explain the purpose of this class and its methods within the CoinJoin process:
@implementation DSCoinJoinSignedInputs +/** + * Creates an instance with the provided data. + * @param data The signed inputs data. + * @return A new DSCoinJoinSignedInputs instance. + */ + (instancetype)requestWithData:(NSData *)data { return [[DSCoinJoinSignedInputs alloc] initWithData:data]; } +/** + * Returns the message type for CoinJoin signed inputs. + * @return The message type string. + */ + (NSString *)type { return MSG_COINJOIN_SIGNED_INPUTS; }
32-46: Consider thread safety for data accessThe implementation stores and accesses the NSData directly, which is generally fine.
Consider implementing defensive copying of the data for better protection against unintended modifications:
- (instancetype)initWithData:(NSData *)data { self = [super init]; if (self) { - _data = data; + _data = [data copy]; // Create a defensive copy } return self; } - (NSString *)type { return DSCoinJoinSignedInputs.type; } - (NSData *)toData { - return self.data; + return [self.data copy]; // Return a copy to prevent external modification }DashSync/shared/Models/Platform/Transitions/BlockchainIdentity/DSBlockchainIdentityCloseTransition.m (1)
90-98: Method signature update correctly propagated to commented codeThe method signature for
toDataWithSubscriptIndex:has been updated to include theanyoneCanPayparameter, and the call to the superclass method has been updated accordingly. This change is consistent with the other transaction classes.Note that this code is actually commented out (appears to be legacy or reference code). Consider either:
- Removing the commented-out code entirely if it's no longer needed, or
- Adding a comment explaining why this implementation is preserved for reference
-//- (NSData *)toDataWithSubscriptIndex:(NSUInteger)subscriptIndex anyoneCanPay:(BOOL)anyoneCanPay -//{ -// NSMutableData * data = [[super toDataWithSubscriptIndex:subscriptIndex anyoneCanPay:anyoneCanPay] mutableCopy]; -// NSData * payloadData = [self payloadData]; -// [data appendVarInt:payloadData.length]; -// [data appendData:payloadData]; -// if (subscriptIndex != NSNotFound) [data appendUInt32:SIGHASH_ALL]; -// return data; -//} +// Removed legacy implementationOr if keeping for reference:
+// Legacy implementation kept for reference - current implementation now in DSBlockchainIdentityCloseTransition.m //- (NSData *)toDataWithSubscriptIndex:(NSUInteger)subscriptIndex anyoneCanPay:(BOOL)anyoneCanPay //{ // NSMutableData * data = [[super toDataWithSubscriptIndex:subscriptIndex anyoneCanPay:anyoneCanPay] mutableCopy];Example/DashSync/DSCoinJoinViewController.m (1)
44-61: startCoinJoin implementation may benefit from additional error handling.The method properly initializes the CoinJoin manager and starts the process, but doesn't handle potential failures or provide user feedback.
Consider adding error handling and user feedback:
- (void)startCoinJoin { if (self.coinJoinManager == NULL) { self.coinJoinManager = [DSCoinJoinManager sharedInstanceForChain:self.chainManager.chain]; } [self.coinJoinManager start]; [self.coinJoinManager refreshUnusedKeys]; [self.coinJoinManager initMasternodeGroup]; [self.coinJoinManager setStopOnNothingToDo:true]; if (![self.coinJoinManager startMixing]) { DSLog(@"[OBJ-C] CoinJoin: Mixing has been started already."); + // Update UI to indicate mixing is already in progress + [self updateStatusWithMessage:@"Mixing already in progress"]; } [self.coinJoinManager doAutomaticDenominatingWithDryRun:NO completion:^(BOOL success) { - + if (success) { + [self updateStatusWithMessage:@"Denominating successful"]; + } else { + [self updateStatusWithMessage:@"Denominating failed"]; + // Consider resetting the switch if the operation failed + dispatch_async(dispatch_get_main_queue(), ^{ + self.coinJoinSwitch.on = NO; + }); + } }]; } +// Helper method to update status +- (void)updateStatusWithMessage:(NSString *)message { + // Update a status label or other UI element + dispatch_async(dispatch_get_main_queue(), ^{ + self.statusLabel.text = message; + }); +}DashSync/shared/Models/CoinJoin/Utils/DSBackoff.h (1)
20-33: New backoff utility class needs documentationThe
DSBackoffclass appears to implement an exponential backoff algorithm for retry mechanisms, which is useful for network operations in CoinJoin. While the implementation looks good, it lacks documentation explaining the purpose and behavior of the class and its methods.Consider adding documentation comments to explain:
- The purpose of the class
- How the backoff algorithm works
- What
trackSuccessandtrackFailuremethods do to the backoff state- The expected usage pattern in CoinJoin contexts
DashSync/shared/Models/CoinJoin/DSCoinJoinBalance.h (1)
23-34: New CoinJoin balance tracking class needs documentationThe
DSCoinJoinBalanceclass introduces multiple properties for tracking various balance states in CoinJoin operations, but lacks documentation explaining what each balance type represents and how they're used.Consider adding documentation comments to explain:
- The purpose of each balance type (trusted, untrusted, denominated, anonymized, etc.)
- How these balances relate to CoinJoin operations
- How watch-only balances differ from regular balances
DashSync/shared/Models/CoinJoin/DSCompactTallyItem.m (2)
31-51: FFI memory allocation is correctly implemented, but could be improved.The method allocates memory for the
CompactTallyItemstructure and its components, including the transaction destination and input coins array. However, there's a potential issue with type handling and an unnecessary variable.Consider these improvements:
- Line 37 creates a
scriptDatavariable unnecessarily - you can passself.txDestinationdirectly todata_malloc- The
txDestinationproperty appears to be accessed as both a string (for length) and data (for content) - ensure the property type is consistent- NSUInteger length = self.txDestination.length; - tallyItem->tx_destination_length = (uintptr_t)length; - NSData *scriptData = self.txDestination; - tallyItem->tx_destination = data_malloc(scriptData); + tallyItem->tx_destination_length = (uintptr_t)self.txDestination.length; + tallyItem->tx_destination = data_malloc(self.txDestination);
53-67: Memory deallocation is thorough but has a type inconsistency.The
ffi_free:method properly frees all allocated memory, including nested structures. However, there's a type inconsistency in the loop counter.For type consistency, consider changing the loop counter type to match the size type:
- for (int i = 0; i < item->input_coins_size; i++) { + for (uintptr_t i = 0; i < item->input_coins_size; i++) {This matches the type used in the
ffi_malloc:method and theinput_coins_sizefield.DashSync/shared/Models/Managers/Chain Managers/DSMasternodeManager.m (1)
164-166: Function signature has changed but is being used as a boolean.The method
hasMasternodeAtLocation:port:now returns aDSSimplifiedMasternodeEntry *object instead of aBOOL, but is still being used in a boolean context by checking if the result is not nil. This change in return type could lead to confusion for callers expecting a boolean value.Consider renaming this method to better reflect its new behavior, such as
findMasternodeAtLocation:port:to clearly indicate it returns an object or nil.DashSync/shared/Models/CoinJoin/DSTransaction+CoinJoin.m (2)
68-70: Improve clarity for NSNull handling.Using
NSNullfor nil addresses that will later be converted to OP_RETURN scripts is a valid approach, but it could be confusing without proper documentation.Consider adding a comment explaining this pattern or create a helper method to make the intention clearer.
- [addresses addObject:address ?: [NSNull null]]; // Use NSNull turned into OP_RETURN script later + // Nil addresses will be converted to OP_RETURN scripts during transaction creation + [addresses addObject:address ?: [NSNull null]];
78-107: Good memory management, but add documentation for FFI functions.The
ffi_malloc:method correctly allocates memory for the Transaction struct and its components. However, as this is part of a Foreign Function Interface (FFI), adding more documentation would help future developers understand these critical memory management functions.- - (Transaction *)ffi_malloc:(ChainType)chainType { + /** + * Allocates and populates a C-style Transaction structure from this Objective-C object. + * Caller is responsible for freeing the memory using +ffi_free: method. + * + * @param chainType The type of chain this transaction belongs to + * @return A pointer to the allocated Transaction structure + */ + - (Transaction *)ffi_malloc:(ChainType)chainType {DashSync/shared/Models/CoinJoin/DSCoinJoinBalance.m (1)
22-44: Consider using a builder pattern for clarity with many parameters.The class method has 9 parameters which makes it difficult to use correctly and maintain. A builder pattern or a dictionary-based approach would make this more manageable.
Alternative approach using a dictionary:
+ /** + * Creates a balance object with the specified balance values. + * + * @param balanceDict Dictionary with keys for each balance type + * @return Initialized DSCoinJoinBalance object + */ + + (DSCoinJoinBalance *)balanceWithDictionary:(NSDictionary *)balanceDict { + DSCoinJoinBalance *balance = [[DSCoinJoinBalance alloc] init]; + balance.myTrusted = [balanceDict[@"myTrusted"] unsignedLongLongValue]; + balance.denominatedTrusted = [balanceDict[@"denominatedTrusted"] unsignedLongLongValue]; + balance.anonymized = [balanceDict[@"anonymized"] unsignedLongLongValue]; + balance.myImmature = [balanceDict[@"myImmature"] unsignedLongLongValue]; + balance.myUntrustedPending = [balanceDict[@"myUntrustedPending"] unsignedLongLongValue]; + balance.denominatedUntrustedPending = [balanceDict[@"denominatedUntrustedPending"] unsignedLongLongValue]; + balance.watchOnlyTrusted = [balanceDict[@"watchOnlyTrusted"] unsignedLongLongValue]; + balance.watchOnlyUntrustedPending = [balanceDict[@"watchOnlyUntrustedPending"] unsignedLongLongValue]; + balance.watchOnlyImmature = [balanceDict[@"watchOnlyImmature"] unsignedLongLongValue]; + + return balance; + }DashSync/shared/Models/Transactions/Base/DSTransaction.h (3)
93-94: Clarify property naming to reduce ambiguity.
Naming properties asdirectionanddashAmountmight lead to confusion in multi-asset contexts or in code that manages BTC-like assets as well. A more descriptive naming pattern such astransactionDirectionandtransactionAmountcould improve clarity.-@property (nonatomic, readonly) DSTransactionDirection direction; -@property (nonatomic, readonly) uint64_t dashAmount; +@property (nonatomic, readonly) DSTransactionDirection transactionDirection; +@property (nonatomic, readonly) uint64_t transactionAmount;
109-109: Confirm alignment with established naming conventions.
The propertyisImmatureCoinBaseis descriptive, but code elsewhere may use variants likeisCoinbaseTransactionorisImmatureCoinbase. Merit verifying or aligning the name across the codebase for consistency.
177-177: Validate the coin maturity flow in specialized transactions.
getBlocksToMaturityhelps identify spendable status for coinbase outputs. Ensure it accounts for all special transaction types that might follow similar maturity rules.DashSync/shared/Libraries/Logs/CompressingLogFileManager.m (3)
1-40: Provide clear logging levels and fallback strategies.
This file introduces custom macros (NSLogError,NSLogWarn, etc.) and a fixedLOG_LEVEL. Consider using the built-in CocoaLumberjack macros or dynamic log levels to allow flexible runtime logging control.
189-225: Confirm operational flow upon compression success/failure.
compressionDidSucceed:callscompressNextLogFile, whilecompressionDidFail:retries after a delay. Ensure that re-trying won't cause repeated indefinite failures, e.g., if there's a permanent filesystem issue.Would you like a helper solution that monitors the number of consecutive failures and escalates if a threshold is reached?
515-561: Use unique naming for temp file paths to avoid collisions.
tempFilePathByAppendingPathExtension:andfileNameByAppendingPathExtension:are straightforward. Confirm that concurrency or multiple processes won't generate the same temp filename simultaneously.DashSync/shared/Models/CoinJoin/DSCoinControl.m (1)
76-87: Use built-in membership check instead of manual loop.Instead of iterating through
self.setSelectedto check membership, you can directly do:return [self.setSelected containsObject:dsutxo_obj(utxo)];This avoids an O(n) loop each time you check a UTXO.
DashSync/shared/Models/CoinJoin/DSCoinControl.h (1)
24-50: Potential for a convenience or builder-style initializer.With many boolean and numeric properties, consider adding a convenience initializer or configuration methods to reduce constructor overload and ensure clarity, especially when toggling multiple coin control options (e.g.,
allowWatchOnly,overrideFeeRate, etc.).DashSync/shared/Models/CoinJoin/DSCoinJoinWrapper.h (1)
33-49: Add usage documentation for newly introduced methods.
These methods facilitate critical steps of the CoinJoin process but have no inline documentation. Briefly explain their purpose, expected parameters, and return behavior to ease onboarding for new developers and to promote clarity.DashSync/shared/Models/Network/DSPeer.m (2)
381-381: Consider removing the commented-out logging.
Leaving logging statements commented out can clutter the code. Remove them or guard them with a debug flag if they are occasionally helpful.-// DSLog(@"%@:%u sendRequest: [%@]: %@", self.host, self.port, type, [payload hexString]);
1823-1842: Watch for concurrency in shared manager calls.
These newacceptCoinJoin*methods delegate to[DSCoinJoinManager sharedInstanceForChain:]. Double-check concurrency protections—multiple peers might asynchronously call the shared manager. Consider locking or queue dispatch if needed to avoid race conditions.DashSync/shared/Models/Wallet/DSAccount.m (4)
166-170: Checking for multiple CoinJoin derivation paths.Your assertion ensures each account can only hold a single CoinJoin derivation path. Great approach for avoiding confusion. Double-check that this scenario never needs multiple such derivation paths in the future.
Consider providing a more descriptive assertion message, for instance:
- NSAssert(TRUE, @"There should only be one CoinJoin derivation path"); + NSAssert(FALSE, @"Duplicate CoinJoin derivation path encountered");
241-241: Minor adjustment in transaction loading.Check if reformatting or a new comment was intended here. The functional change is unclear.
If this is only a spacing fix, consider combining it with other relevant changes for clarity.
483-505: ExtendingregisterAddressesWithGapLimit:(...)coinJoinGapLimit:(...)error:.You handle three different gap limits: normal, DashPay, and CoinJoin. Encouraging separation of concerns. The expanded logic is consistent. Validate test coverage to ensure coinJoinGapLimit is applied correctly.
Consider extracting the gapLimiting logic into a small helper function for readability, especially as you add more path types in the future.
713-759: Refined transaction size/locktime checks withinupdateBalance.You’ve introduced or adjusted logging and validation for transaction sizes, lockTimes, dust outputs, etc. This is beneficial for security and consistency. However, large blocks of #if DEBUG logging can become unwieldy.
Consider grouping the debug logs and adding more descriptive log statements to help with production debugging.
DashSync/shared/Models/CoinJoin/Utils/DSMasternodeGroup.m (6)
37-56: Private properties and interface.Properties effectively unify group logic for masternodes, sessions, pending states, and backoff logic. Atomic usage of
_maxConnectionsis consistent but ensure thread safety for other mutable properties.You might consider marking
_maxConnectionsatomic or using synchronized reads where needed for absolute safety.
83-91:- startAsync
Sets_isRunningto true, registers sync-state notifications, triggers connections. Straightforward. Ensure that repeated calls don’t accidentally re-subscribe notifications or lead to concurrency issues.If
startAsynccan be called multiple times, consider unsubscribing prior to re-subscribing to avoid duplicates.
101-115:- isMasternodeOrDisconnectRequested:port:
Checks if a masternode is in connected or pending closure sets. Straight to the point.For clarity, rename to
isMasternodeConnectedOrPendingDisconnect:to convey the meaning more precisely.
194-245:- triggerConnectionsJobWithDelay:
Schedules connections after a delay, checks chain sync status, ensures we have not exceeded max connections, and tries to get the next peer. Good structure.Consider separating the environment checks (e.g., chain sync, new block wait, mixing enabled) into a smaller method for clarity.
409-459:- connectTo:
Checks if peer is a valid masternode session, sets up delegates, and attempts to connect. Key logic for initiating new connections. Possibly add extra checks for spurious repeated connections.Log a warning if
peeris already connecting or connected to avoid spamming reconnections.
499-554:- peer:disconnectedWithError:
Removes peer from pending/connected sets, updates backoff, and triggers reconnection if needed. Also checks if that peer was in the pending-closing list and cleans up session references. Well-structured.Consider splitting the logic for normal disconnect vs. an intended closure to keep it simpler.
DashSync/shared/Models/CoinJoin/DSCoinJoinWrapper.m (3)
43-51:- registerCoinJoin:
Initializes the Rust client manager via FFI. This is critical. Ensure that subsequent calls don’t inadvertently re-register or leak memory.Add clarity around repeated calls. If
clientManageris already set, do you skip re-registering?
133-147:- processMessageFrom:message:type:
Similar bridging, but includes a message type. Freed after usage. Looks correct.Validate that the string length for
message_typein Rust can handle arbitrary input.
279-284:- dealloc
Unregisters the client manager to free resources. Ensure no further references to_clientManagerremain.Potentially ensure a shutdown or stop logic is invoked prior for a graceful teardown.
DashSync/shared/Models/Wallet/DSAccount.h (6)
57-58: Ensure property is clearly documented.
coinJoinDerivationPathis a helpful read-only property. Consider adding a short doc comment describing its intended usage (e.g., how addresses are derived, whether it's created eagerly or lazily, etc.).
100-111: Clarify naming and usage of CoinJoin address arrays.
The new properties (coinJoinReceiveAddress,coinJoinChangeAddress,usedCoinJoinReceiveAddresses,allCoinJoinReceiveAddresses) suggest different sets of addresses (e.g., "used" vs. "all"). Consider clarifying the naming or associated doc comments to prevent confusion, especially distinguishing "issued" from "used".
118-118: Consider simplifying the parameter list.
The additionalcoinJoinGapLimitparameter might be consolidated (e.g., using a config object) if more parameters are added in the future. This can improve readability and reduce method signature length.
198-203: Complete the doc comment.
The doc comment here is partially empty between lines 198–203. Consider adding details, for instance, clarifying whether it prompts for a passphrase or how the result is returned.
205-215: Check method name overlap.
We now have twosignTransaction:methods. For clarity, you could unify or rename them to highlight theanyoneCanPay:parameter. This helps avoid confusion and clarifies usage.
283-285: Consider returning a typed array.
- (NSArray *)amountsSentByTransaction:could returnNSArray<NSNumber *> *for stronger type checking.DashSync/shared/Models/Managers/Chain Managers/DSTransactionManager.m (5)
290-294: Review PII or sensitive data logging.
DSLogPrivatemight reveal transaction details or hashes. Confirm that this usage aligns with the privacy and logging guidelines.
307-308: Minor style consistency.
DeclaringBOOL updateTransaction = NO;and a blank line might break code style consistency. Consider removing extra blank lines if not needed.
1141-1148: Standardize error handling.
Returning an NSError with code 401 for double spend might be conflated with 401 Unauthorized in some contexts. Consider custom error domain or code for double-spend conflicts, or ensure clarity around the meaning of 401 here.
1785-1791: Nested async block.
Dispatching withindispatch_asynccan be simplified if no additional checks are needed. Otherwise, ensure it doesn't cause unexpected delays.
1139-1148: Double spend error:
Here, a 401 code is used to signify “Double spend.” While functional, consider adding a dedicated error code for clarity.- error = [NSError errorWithCode:401 localizedDescriptionKey:@"Double spend"]; + // optionally define a distinct code for double spend scenario + error = [NSError errorWithCode:DSErrorDoubleSpend localizedDescriptionKey:@"Double spend"];DashSync/shared/Models/CoinJoin/DSCoinJoinManager.h (2)
57-95: Broad method set for management.
These methods expand functionality significantly. If this file grows, consider grouping them by category (e.g., “Masternode Management,” “Coin Selection,” “Mixing Lifecycle”) to improve maintainability. Also ensure concurrency handling if mixing runs on multiple threads.
96-102: Event handler naming.
Methods likeonSessionComplete:,onMixingComplete:, etc. are consistent in prefixing with "on". However, consider standard naming for clarity, e.g.,notifyMixingComplete:ordidCompleteMixing:.DashSync/shared/Models/CoinJoin/DSCoinJoinManager.m (2)
39-41: Consider clarifying default constants.The arbitrary values for
DEFAULT_MAX_DEPTHandMIN_BLOCKS_TO_WAITmight benefit from explanatory comments or self-documenting names. This can help future maintainers understand why these values were chosen.
374-491: Potential performance concern with large unspent sets.This method iterates over all unspent outputs, checks conditions, and accumulates results for each. For large wallets, this can become expensive. Consider either indexing unspent outputs by address, or caching frequently used data to reduce computational overhead.

2-2: Updated interface builder tools version.The storyboard file has been updated to use the newer versions of Xcode tools: InterfaceBuilder and IBCocoaTouchPlugin. This is a standard update when working with a newer version of Xcode.
Also applies to: 6-6
84-84: Background color change improves UI layering.The header view background color has been changed from white to transparent (alpha 0), which allows for better visual layering in the UI hierarchy. This is a good UI improvement that will make the interface appear less cluttered.
124-1543: Layout positioning adjustments for table view cells.These changes represent automatic adjustments to frame rectangles, positions, and constraints in the storyboard. These are generated by Interface Builder when layouts are modified and don't require manual review as they're derived from higher-level design changes.
1-2989: Missing explicit CoinJoin UI elements for feature implementation.While the PR title and AI summary reference CoinJoin functionality, I don't see any explicit UI elements (labels, view controllers, table cells) named "CoinJoin" in this storyboard file. Ensure the CoinJoin feature is properly exposed in the UI if that's the intention of this PR.
Could you verify if the CoinJoin UI elements are defined in another storyboard file or implemented programmatically? This would help ensure the feature is properly exposed to users.

18-18: Verify test coverage for CoinJoin functionalityThe
DSCoinJoinSessionTesthas been added to the skipped tests list. Since this PR implements CoinJoin functionality, skipping this test raises questions about how the feature is being validated.Could you explain why this test is being skipped? Is there alternative test coverage for CoinJoin functionality in other test plans or through different means? Please ensure that the CoinJoin implementation is adequately tested through other test cases or methods.
Example/Tests/LibraryTests.xctestplan (1)
26-26: Skip configuration for CoinJoin session test added.The test
DSCoinJoinSessionTesthas been added to the skipped tests list. This appears to be part of a broader pattern where this test is being skipped across multiple test plans. Is there a specific reason for excluding this test from regular execution? Please consider adding a comment or creating a ticket to track the rationale and any plans to enable this test in the future.Example/Tests/DerivationTests.xctestplan (1)
25-25: CoinJoin session test consistently skipped across test plans.The
DSCoinJoinSessionTesthas been added to the skipped tests list, consistent with changes in other test plans. While skipping tests can be necessary, it's important to document why this test is being excluded across multiple plans. Is this due to test instability, performance concerns, or specific environmental requirements?Example/Tests/TestnetE2ETests.xctestplan (1)
25-25: CoinJoin test skipping pattern continues in E2E tests.The
DSCoinJoinSessionTesthas been added to the skipped tests list here as well, following the same pattern seen in other test plans. Given that the PR mentions CI error resolution, is skipping this test a temporary measure to get the feature merged, or will it remain skipped permanently? If temporary, consider adding a TODO comment with a ticket reference.Example/Tests/MasternodeListTests.xctestplan (1)
26-26: Test skipping pattern confirmed across multiple test plans.The addition of
DSCoinJoinSessionTestto the skipped tests list is consistent with changes in other test plans. Since this appears to be a deliberate pattern, it would be beneficial to:
- Document the reason for skipping these tests
- Create a ticket to track re-enabling them if they're meant to be temporary
- Consider adding a comment in the test itself explaining why it's skipped
This consistent approach ensures the test configuration remains maintainable as the CoinJoin feature evolves.

25-25: Consistent test skipping across test plansThe addition of DSCoinJoinSessionTest to the skipped tests is consistent with the changes made to other test plans. This is a good practice to ensure consistent test behavior across different test configurations.
DashSync/shared/Models/Chain/DSChainConstants.h (1)
86-86: Appropriate addition of COINBASE_MATURITY constantThe addition of the COINBASE_MATURITY constant with a value of 100 is correct and follows standard blockchain practices. This constant defines that coinbase transaction outputs can only be spent after 100 new blocks, which is an important parameter for transaction validation and will be particularly relevant for the CoinJoin feature being implemented.

The updated step correctly adds CocoaPods setup after the Rustup target step. Pinning the CocoaPods version to1.15.2helps maintain uniformity across workflows. Consider monitoring future CocoaPods releases for any potential required updates..github/workflows/e2eTestsTestnet.yml (1)
48-51: E2E Tests Workflow – CocoaPods Setup Step
The newly introduced "Setup CocoaPods" step usingmaxim-lobanov/setup-cocoapods@v1with version1.15.2is placed appropriately after adding Rust targets and before dependency installation. This change aligns the E2E tests setup with other workflows, ensuring dependable dependency management for iOS components.Example/DashSync.xcodeproj/project.pbxproj (6)
69-70: New CoinJoin files added to the projectThe project has been updated to include the new CoinJoin functionality with:
DSCoinJoinSessionTest.mfor testing CoinJoin sessionsDSCoinJoinViewController.mfor the user interfaceThese additions align with the PR's goal of integrating CoinJoin functionality.
623-626: File references for CoinJoin implementation addedThe project now includes:
- A dedicated test plan for CoinJoin tests
- Header and implementation files for the CoinJoin view controller
This provides a good structure for the new feature implementation.
1471-1471: Organized test structure with dedicated CoinJoin groupAdding a specific test group for CoinJoin tests helps maintain a clean organization of test files.
2072-2073: CoinJoin view controller added to Actions groupThe view controller is appropriately placed in the Actions group alongside other action-related controllers.
3202-3202: Verify impact of enabling fast math optimizationsThe project now uses
GCC_FAST_MATH = YESfor both debug and release builds. While this can improve performance, it may affect floating-point calculations by:
- Disabling IEEE 754 compliance checks
- Assuming NaN values don't occur
- Eliminating division by zero checks
Consider verifying if CoinJoin operations involve critical floating-point calculations that might be affected by these optimizations. If precision is crucial for cryptographic operations, this setting might need reconsideration.

Verify if the large gap limit value is necessary for CoinJoin.
The newly added constant
SEQUENCE_GAP_LIMIT_INITIAL_COINJOINis set to 400, which is significantly higher than other gap limits (e.g.,SEQUENCE_GAP_LIMIT_INITIALis 100). While this may be intentional for CoinJoin operations which typically require more addresses, ensure this value isn't unnecessarily large as it could impact performance when scanning the blockchain.
🏁 Script executed:
#!/bin/bash # Look for uses of this constant to understand its impact echo "Searching for uses of SEQUENCE_GAP_LIMIT_INITIAL_COINJOIN constant..." rg -A 3 "SEQUENCE_GAP_LIMIT_INITIAL_COINJOIN" echo "Checking if there are special load address implementations for CoinJoin..." rg "loadAddresses.*CoinJoin" -A 5Length of output: 3182
Confirm the Justification for a 400-Gap Limit on CoinJoin
I've confirmed that the constant
SEQUENCE_GAP_LIMIT_INITIAL_COINJOINis indeed used in several parts of the codebase (inDSFundsDerivationPath.h,DSTransactionManager.m, andDSChain.m) and is passed as the parameter for registering addresses within CoinJoin operations. There is no specialized address-loading logic for CoinJoin—CoinJoin simply relies on this higher gap limit compared to the standard (100) gap limit.Please verify that setting the gap limit to 400 is intentional based on CoinJoin's operational requirements and performance benchmarks. If 400 is necessary to support CoinJoin properly, consider adding a brief comment in the code explaining this rationale to assist future maintainers. Otherwise, revisiting this value may help optimize blockchain scanning performance.

Security concern: Method added to access seed without authentication
The addition of
requestSeedNoAuthmethod raises security concerns as it appears to provide access to the wallet's seed data without requiring authentication.While this may be necessary for CoinJoin operations, accessing the seed without authentication could potentially expose sensitive cryptographic material if not properly controlled.
Please verify that:
- This method is only used in secure contexts
- There are appropriate safeguards to prevent unauthorized access

Declaration & Implementation:
- The method is declared in
DashSync/shared/Models/Wallet/DSWallet+Protected.hand implemented inDashSync/shared/Models/Wallet/DSWallet.m.- The implementation includes a comment clarifying that this method is invoked “when we request the seed without a pin code,” suggesting it’s meant for specific use cases (e.g., CoinJoin operations).
Usage Context:
- In
DashSync/shared/Models/Wallet/DSAccount.m, the method is called within an@autoreleasepoolintended to manage sensitive data, reinforcing that its use is confined to controlled internal operations.Recommendations:
- Secure Context Assumptions: Ensure that every invocation of
requestSeedNoAuthis indeed limited to the intended secure contexts (e.g., during CoinJoin operations).- Access Controls: Confirm that higher-level components (or surrounding methods) enforce proper safeguards so that no unauthorized part of the codebase can access seed data unexpectedly.
- Documentation: It might be beneficial to add explicit comments or documentation that outline the intended use and any protection mechanisms that exist, to prevent accidental misuse in the future.

Missing CoinJoin UI elements
Despite the PR being focused on adding CoinJoin functionality, there doesn't appear to be any new UI elements or controllers specific to CoinJoin in this storyboard. Consider adding CoinJoin-specific UI components to enable user interaction with the new feature.
Let's verify if CoinJoin UI elements might be defined in other storyboard files:
🏁 Script executed:

CoinJoin UI Is Present, But in the Correct Location
After verifying, the CoinJoin-specific UI components are implemented in the Actions storyboard—not in Contacts.storyboard. In particular:
- The Actions storyboard (located at Example/DashSync/Actions.storyboard) contains a label with the text "CoinJoin" and a segue (identifier "CoinJoinSeque") that leads to the DSCoinJoinViewController.
- The CoinJoin view controller (DSCoinJoinViewController) is correctly defined and wired (including its coinJoinSwitch outlet).
Based on this, the absence of CoinJoin UI elements in Contacts.storyboard is expected. Please confirm that this separation aligns with the intended design.

46-59: LGTM! Good memory allocation with proper field mapping.The
ffi_mallocmethod correctly allocates and populates a C-style Balance structure. Each property is properly mapped from the Objective-C object to the C structure.
61-65: LGTM! Proper null check before freeing memory.The
ffi_free:method correctly checks if the balance pointer is not null before freeing it, preventing potential crashes.DashSync/shared/Models/Network/DSPeer.h (2)
140-149: LGTM! Clean transition from Darksend to CoinJoin message constants.The changes replace Darksend message constants with CoinJoin message constants, which aligns with the broader update to implement CoinJoin functionality across the codebase. The new constants follow a consistent naming convention.
140-149: Additions for CoinJoin message definitions look consistent.
All new message constants follow a coherent naming pattern. They align well with existing prefixes (MSG_COINJOIN_).DashSync/shared/Models/Transactions/Base/DSTransaction.h (3)
51-51: Ensure consistent usage documentation for the new sighash flag.
The newly introducedSIGHASH_ANYONECANPAYflag is a valuable addition for advanced transaction signing scenarios. To aid future maintainers, consider adding usage notes or relevant references (e.g., BIP143, BIP145) explaining when and why this flag is triggered.
149-149:Details
✅ Verification successful
Request verification of updated calls to the extended sign method.
The new parameteranyoneCanPayextendssignWithPrivateKeys:. Verify all call sites of this API have been updated to pass or handleanyoneCanPay.
🏁 Script executed:
#!/bin/bash rg "signWithPrivateKeys:.*anyoneCanPay:"Length of output: 542
All call sites properly updated
Verification shows that every invocation of
signWithPrivateKeys:now includes theanyoneCanPayparameter. In particular:
- DashSync/shared/Models/Wallet/DSAccount.m – Calls
signWithPrivateKeys:privkeys anyoneCanPay:anyoneCanPayas expected.- DashSync/shared/Models/Transactions/Base/DSTransaction.m – Calls
signWithPrivateKeys:keys anyoneCanPay:NOand the method definition correctly includes the new parameter.No further modifications are necessary.
159-159:Details
❓ Verification inconclusive
Check interaction between subscript index and SIGHASH options.
The subscript index is crucial when generating partial signatures. Ensure the newanyoneCanPayparameter is properly integrated with subscript logic to avoid partial signing bugs.
🏁 Script executed:
#!/bin/bash rg "toDataWithSubscriptIndex:.*anyoneCanPay:"Length of output: 3504
Critical: Verify Subscript–SIGHASH Interaction in Partial Signature Generation
Please ensure that the newanyoneCanPayparameter is correctly integrated with the subscript index logic across all transaction signing paths. In particular:
- Verify that when a valid subscript index is passed (or when
NSNotFoundis used), the resulting data correctly reflects the intended SIGHASH behavior.- Confirm that all call sites (e.g., in DSAssetLockTransaction, DSAssetUnlockTransaction, DSProvider transactions, and others) consistently forward the
anyoneCanPayparameter without disrupting the partial signature generation process.- Double-check that the updated logic does not inadvertently alter the expected SIGHASH flags when generating the signature hash.
Please review these interactions carefully during testing to rule out any potential partial signing issues.
DashSync/shared/Libraries/Logs/CompressingLogFileManager.m (3)
49-80: Consider concurrency constraints during initialization.
WithininitWithFileSize:andinitWithLogsDirectory:, the delayed call tocompressNextLogFilemight compete with other file operations. Verify that no race conditions occur if multiple threads call initialization methods simultaneously.
134-188: Validate file filtering and retention logic.
The methodhandleProcessorLogRotationWithSortedLogs:purges logs older than five days and sorts them by date. Confirm that files with unusual naming or date formats do not accidentally remain uncompressed.
227-508: Check buffer sizes and partial write loops for edge cases.
The main compression loop handles partial reads/writes and manages leftover input data. Verify negative or zero-length corner cases—especially if an empty file or I/O error occurs while partially compressing.DashSync/shared/Models/Wallet/DSWallet.m (1)
858-862:Details
❓ Verification inconclusive
Confirm coinJoinGapLimit usage throughout the address derivation.
AddingcoinJoinGapLimitmodifies address registration logic. Ensure the code that triggers or references this gap limit properly aligns with the new parameter.
🏁 Script executed:
#!/bin/bash rg "coinJoinGapLimit"Length of output: 2863
Confirm CoinJoinGapLimit Propagation and Alignment
The coinJoinGapLimit parameter is now consistently propagated through the address registration chain:
- In DSWallet, the parameter is passed to each account via
registerAddressesWithGapLimit:unusedAccountGapLimit:dashpayGapLimit:coinJoinGapLimit:internal:error:.- In DSAccount, it is correctly applied by setting
registerGapLimit = coinJoinGapLimit.- In DSTransactionManager and DSChain, calls to register addresses use the predefined gap limits (e.g.,
SEQUENCE_GAP_LIMIT_INITIAL_COINJOIN), which correspond to the coinJoinGapLimit usage.Please verify that these macros and parameter values align with the intended coin join address derivation logic and that no downstream logic is inadvertently bypassing or misinterpreting the coinJoinGapLimit.
DashSync/shared/Models/Transactions/Base/DSTransaction.m (4)
326-366: Validate partial transaction logic.Returning
UINT64_MAXfor a partial or incorrect sync scenario (line 348) may mask potential issues. Consider adding logging or additional checks to alert you when underlying transaction data may be incomplete, instead of silently returningUINT64_MAX.
369-377: Cached direction fallback.When
cachedDirectionisDSTransactionDirection_NotAccountFunds, you recalculate its direction and then cache it. This logic appears correct, but ensure subsequent path logic (such as UI updates or fee calculations) properly handles the newly cached direction.
423-434: Coinbase maturity check.These new methods correctly account for Dash’s coinbase maturity rules. Confirm that
COINBASE_MATURITY + 1remains consistent with network parameters if upgraded in the future.
648-690: Check concurrency for signing.Using
@synchronized(self)here ensures thread safety while signing. This approach looks good. However, if multiple threads sign different transactions simultaneously, cross-class concurrency concerns could still exist. Confirm that upper-level orchestration properly manages multi-transaction concurrency.DashSync/shared/Models/Network/DSPeer.m (3)
67-67: Import addition looks good.
Including"DSCoinJoinManager.h"is essential for handling CoinJoin messages.
848-858: Confirm that CoinJoin message handling is fully tested.
The new conditionals forMSG_COINJOIN_*types effectively route messages to the CoinJoin manager. Ensure thorough coverage in the integration tests to detect potential regressions quickly.
1067-1067: Validate the DSInvType_DSTx scenario.
AddingDSInvType_DSTxto handle special transaction broadcasts is logical. However, ensure any fallback behavior in the surrounding logic remains correct. Verify no unhandled or unintended DSInvType cases remain, especially when toggling between standard transactions and DSTx.DashSync/shared/Models/Managers/Chain Managers/DSTransactionManager.h (2)
89-89: Verify 'mixedOnly' usage in transaction flows.
The newmixedOnlyparameter expands the method’s functionality to handle exclusively mixed transactions. Ensure downstream call sites and test scenarios are updated to reflect the new argument, preventing silent failures.
101-101: Ensure 'mixedOnly' is properly integrated in protocol requests.
Similar to the sign-and-publish flow, confirm that the code path callingconfirmProtocolRequest:...handlesmixedOnlyconsistently. This prevents logical gaps when toggling the mixing requirement.DashSync/shared/Models/Wallet/DSAccount.m (14)
64-64: Noting the new import statement.Importing
"DSCoinControl.h"suggests you're preparing for selective coin control or advanced transaction handling. Ensure this file doesn't introduce circular dependencies or unused imports.
113-114: Introducing a dedicated property for CoinJoin derivation path.Declaring a
coinJoinDerivationPathas a strong property is a clear step toward separating anonymous (CoinJoin) funds. Confirm usage across the codebase to ensure it’s strictly used for CoinJoin-related addresses.
185-186: Input validation.
NSParameterAssert(derivationPaths);again helps ensure you never initialize an account with empty derivation paths. Looks good in preventing invalid states.
210-211: Input validation.Likewise, verifying
derivationPathsfor the view-only initializer is consistent. No concerns.
215-215: Empty line removed or added.A negligible formatting adjustment. No issues noted from a functionality perspective.
246-247: Revisiting fetch request logic.It’s unclear what changed beyond potential whitespace or comments. Ensure that any removed or added lines don’t break the fetch logic for
DSTxOutputEntity.Please confirm if the fetch request logic remains identical (e.g., same predicate) with no side effects.
350-357: IntroducingcoinJoinReceiveAddress.Returns the first unused CoinJoin address, then registers it. The synchronous dispatch on
networkingQueueis consistent with your concurrency approach.
359-366: IntroducingcoinJoinChangeAddress.Similarly, returns the first unused CoinJoin change address and ensures it’s registered. This will help isolate mixing funds. Implementation is consistent with the receive method.
368-370: Getter for all CoinJoin receive addresses.Lists all derived addresses for CoinJoin receiving. Straightforward addition.
372-374: Getter for used CoinJoin receive addresses.Mirrors the typical pattern from the base wallet logic.

- Confirm that no concurrency race occurs if the manager is deallocated while callbacks are still in progress.
DashSync/shared/Models/Wallet/DSAccount.h (15)
29-29: No concerns about the new import.
This line simply adds theDSCoinControlimport, which is presumably required by new methods.
150-152: Method name looks consistent.
containsCoinJoinAddress:complements the existingcontainsAddress:methods. No issues found.
184-185: Extending transaction creation with coinControl.
Allowing coin selection is beneficial for advanced transaction building. This addition looks well-structured.

Differentiating this from the existing transaction-based lookups can be useful for specialized scenarios.
283-285: amountsSentByTransaction
Returning an array of individual amounts offers granular insight into the transaction’s output distribution.DashSync/shared/Models/Managers/Chain Managers/DSTransactionManager.m (13)
56-56: Import of DSCoinJoinManager looks valid.
Confirm that it's truly needed in this implementation file to avoid unnecessary coupling.
216-222: Notification dispatch on main thread.
Posting theDSTransactionManagerTransactionStatusDidChangeNotificationis a good approach. Keep an eye on concurrency or potential race conditions if related states are modified simultaneously elsewhere.
343-344: Check logic for setting updateTransaction.
Confirm that markingupdateTransaction = YES;here appropriately reflects the condition under which a transaction is removed from the local sets.
354-358: Concise flow control.
SettingupdateTransaction = YES;and then checking it in the subsequent block is straightforward. No immediate issues identified.
56-56: Importing DSCoinJoinManager

214-223: Posting TransactionStatusDidChangeNotification on main queue
Triggering the status change event on the main thread is best practice for UI updates.
613-618: Conditional coinControl assignment
Including coinControl when mixedOnly is true integrates well with DSCoinJoinManager.
Consider verifying if an empty UTXO selection might lead to user feedback on insufficient funds.
668-668: Use of the mixedOnly parameter
Forwarding the mixedOnly flag ensures the correct coinControl logic in signAndPublishTransaction.
673-673: New signAndPublishTransaction signature
Accepting mixedOnly broadens flexible transaction publishing scenarios for CoinJoin.
680-681: MixedOnly parameter in insufficientFunds handling
Passing mixedOnly to handle specialized insufficient fund logic for mixing scenarios is an apt extension.Also applies to: 689-689
839-839: Introducing mixedOnly parameter
The extended method signature clarifies usage in advanced mixing flows.
874-874: Propagating mixedOnly
Ensuring the newly introduced argument is applied consistently across calls avoids confusion.
1791-1794: Additional check for nil chain/block
Logging a warning if either is nil helps diagnose unexpected states with chain locks.DashSync/shared/Models/CoinJoin/DSCoinJoinManager.h (5)
1-29: License header and imports look fine.
These lines form the MIT License header and bring in relevant headers. No further concerns.
30-39: Delegate protocol structure.
All methods are clearly named, referencing session IDs and statuses. No major issues at a glance. If needed, document threading assumptions for each callback.
40-53: Check property ownership semantics.
chainis declared asassignwhile other object properties usestrongorweak. Typically, Objective-C objects usestrongorweak. Consider verifying that no retain cycle issues occur or thatchainwon't be deallocated unexpectedly.
54-56: Singleton initialization.
sharedInstanceForChain:is introduced. Verify concurrency safety if it's truly a singleton or if multiple calls are expected. Consider a thread-safe approach (likedispatch_once).
103-106: File termination is standard.
NS_ASSUME_NONNULL_ENDis present, and the file ends cleanly. No issues.DashSync/shared/Models/CoinJoin/DSCoinJoinManager.m (4)
50-51: Atomic properties for concurrency look good.Using
atomicforhasReportedSuccessandhasReportedFailurehelps ensure they are thread-safe when mutated from different queues.
178-197: Event observer is properly balanced.You add the transaction received observer here and then remove all observers in
stopAsync. This balanced approach prevents potential memory leaks and stale observers.
304-323: Concurrency handling is sound.Dispatching to
self.processingQueuewhile trackinghasReportedSuccessandhasReportedFailureensures consistent and thread-safe variable updates.
1008-1030: Graceful handling of multiple pool statuses.Your logic correctly iterates through multiple statuses, detecting the first non-error one to finalize a successful outcome. This approach is clear, and fallback behavior for error statuses seems consistent.
Issue being fixed or feature implemented
We still need to merge CoinJoin into master since it's been released. There were some CI errors that prevented merging, hopefully resolved now.
