CDK release v0.14.0

Summary

This release focuses on reliability and robustness improvements across the codebase. The mint now implements saga patterns for both melt and swap operations, providing better error recovery and state consistency during these critical operations. Async melt processing has been added for improved throughput. The wallet gains a new Tor mint connector with isolated circuits support for enhanced privacy when communicating with mints, along with a MintMetadataCache that delivers significant performance improvements for key and metadata management. A new proof recovery mechanism automatically handles failed wallet operations. MultiMintWallet receives improvements including the ability to check and wait for mint quotes and configure internal wallets. NUT-11 SIG_ALL message aggregation has been updated to match the latest specification. On the infrastructure side, a generic pubsub module has been introduced in cdk-common, and cdk-ffi adds postgres support. Additional highlights include keyset amount tracking and SQL balance calculation optimization for improved performance, wallet functions to pay human readable addresses (BIP353 and Lightning address), invoice decoding for BOLT11 and BOLT12 in the FFI bindings, and a mutation testing infrastructure to ensure security-critical code coverage. The release also brings numerous bug fixes addressing database contention, HTLC witness handling, and quote state management.

CDK Release


Version 0.13.0 marks a major milestone for mobile development with the introduction of comprehensive native mobile bindings that enable building Cashu wallets for iOS and Android using Swift and Kotlin. The release introduces cdk-ffi, a new Foreign Function Interface crate that provides UniFFI-based bindings for Swift and Kotlin, with full wallet functionality including multi-mint support, BOLT12 payments, BIP-353 address resolution, and advanced features like P2PK conditions and authentication. Mobile bindings are distributed through dedicated repositories at https://github.com/cashubtc/cdk-kotlin and https://github.com/cashubtc/cdk-swift that provide native package management for Android/JVM and iOS/macOS platforms respectively. The release also delivers significant infrastructure improvements including an event-driven payment architecture with real-time notifications, enhanced database layer with generic key-value storage, improved HTTP transport with proxy support and BIP-353 DNS resolution, and new operational features like Prometheus metrics collection and dedicated authentication database support.
