PROFILE

Xavier Brochard

Xavier Alexandre Brochard contributed to MetaMask’s accounts and core repositories by standardizing Solana signature encoding and optimizing asset rate fetching workflows. He updated Solana methods to use base58 encoding for signatures, aligning the MetaMask/accounts API with Solana standards and improving documentation with real data examples. In MetaMask/core, he addressed a bug in the MultichainAssetsRatesController by implementing an early-return guard, preventing unnecessary network calls when no assets are present and adding automated tests to ensure reliability. His work demonstrated proficiency in TypeScript, Node.js, and backend development, delivering targeted improvements that enhanced interoperability, stability, and developer experience.
