Cleun developed foundational multichain support for MetaMask/core by introducing the MultichainNetworkController, enabling seamless network and account switching across both EVM and non-EVM chains. This work involved a robust refactor of switching logic and updates to dependent controllers, laying the groundwork for scalable cross-chain features and reducing user friction. Using TypeScript, JavaScript, and Node.js, Cleun focused on maintainable architecture and full stack development. Additionally, Cleun improved CI reliability in MetaMask/github-tools by updating the GitHub Actions Xcode version, resolving Swift module compilation errors and enhancing developer feedback. The work demonstrated depth in both backend systems and developer tooling.
