PROFILE
Sébastien Van Eyck
Over a two-month period, this developer contributed to MetaMask/core by delivering foundational hardware wallet support and refactoring transaction intent handling. They introduced a dedicated keyring type for OneKey, enabling standalone device recognition and distinct account management, which established a modular pattern for future hardware wallet integrations. In a subsequent project, they refactored the Bridge Status Controller to centralize intent handling and signing, incorporating EIP-712 typedData validation and improving transaction status syncing with per-order caching. Their work relied on TypeScript, Node.js, and full stack development skills, with a focus on robust key management, API integration, and comprehensive testing practices.
