Feb 1, 2025In February 2025, the yttrium repository focused on packaging and build reliability to support smoother cross-language integration. Upgraded Yttrium XCFramework to v0.8.21 with updates to download URL and checksum in Package.swift and YttriumWrapper.podspec. Reorganized headers under yttriumFFI for better maintainability, and refactored build scripts to ensure Swift sources are copied and headers are structured consistently. These changes reduce downstream integration friction and improve multi-platform packaging.

Nov 1, 2024Month: 2024-11. Delivered robust cross-language signing improvements and Swift bindings for Chain Abstraction in reown-com/yttrium. Signing API overhaul with ERC-6492 integration exposed prepare, sign, and finalize methods on the Swift AccountClient, with improved Rust FFI error handling and an updated erc6492 crate on main. Implemented Chain Abstraction Swift bindings including ChainAbstractionClient and EthTransaction, with FFI definitions and Rust-side support for serialization/deserialization. Refactored signing workflow to PreparedSign, updating AccountClient API as needed. These changes reduce integration risk, enable smoother mobile-to-blockchain interactions, and lay groundwork for future CA features.
