Over the past ten months, Hippocampus contributed to the xchainjs-lib and related repositories by engineering multi-chain blockchain integrations, optimizing transaction handling, and modernizing build systems. They delivered features such as Cardano and Zcash support, browser compatibility, and WASM-accelerated modules, while also enhancing security and automation through CI/CD improvements and dependency management. Using TypeScript, JavaScript, and Node.js, Hippocampus implemented robust API integrations, wallet management, and cross-chain interoperability. Their work addressed reliability, data integrity, and cost efficiency, with thorough testing and code refactoring. This depth of engineering improved stability, accelerated release cycles, and enabled seamless blockchain development across multiple platforms.

September 2025: Delivered targeted improvements in xchainjs-lib that boost flexibility, security, and reliability. The Midgard query gained a new asset decimals override via a constructor map, enabling precise per-asset decimal handling and safer financial calculations. CI/build tooling was expanded to include security checks for compromised npm packages and overdue dependency updates (axios), strengthening the project’s security posture. A Discord notification fix ensured alerts are delivered reliably, improving incident visibility. Repository housekeeping included a placeholder commit to maintain PR discipline. Collectively, these changes reduce risk, accelerate feature delivery, and improve downstream integration quality.

Monthly summary for 2025-05 for xchainjs-lib: Delivered cross-chain data enhancements, reliability improvements, and build stability. Key outcomes include Etherscan V2 API integration across all major EVM chains (Arbitrum, Avalanche, Base, BSC, Ethereum, etc.), updating data providers to fetch transaction history using the new API, and updating end-to-end tests; added a changeset for versioning. Implemented transaction cost optimization for BSC and ETH with enhanced THORChain deposit error handling, reducing costs and increasing reliability. Removed stale-issue auto-close workflow to prevent unintended closures, improving issue workflow reliability. Upgraded core dependencies (@chainflip, @ledgerhq, Solana libraries) and fixed a build issue to boost stability and security. Overall impact: improved data fidelity and visibility, lower operating costs, higher reliability, and stronger security posture.
