During December 2025, this developer expanded blockchain network support in the wevm/viem repository by delivering Somnia Mainnet integration. They introduced a new TypeScript module, somnia.ts, and updated the chain registry to include Somnia’s RPC endpoints and block explorer details, enabling Viem-based applications to connect seamlessly to the new network. Their work involved careful API integration and configuration updates to ensure compatibility across the codebase. Additionally, they prepared a changeset to document the feature for release notes and user documentation. The focus remained on feature delivery, with minor configuration and documentation improvements but no major bug fixes during this period.
