Fabien Coutant developed and maintained multi-chain token-list infrastructure across repositories such as balancer/tokenlists and lifinance/customized-token-list, focusing on asset discoverability and cross-network consistency. He implemented token integrations, metadata management, and configuration updates using TypeScript, Solidity, and JSON, enabling seamless onboarding of new assets and networks. His work included cross-repo collaboration for real-time price data integration, code quality improvements, and precise chainId handling to reduce misidentification risks. By establishing scalable integration patterns and maintaining commit-level traceability, Fabien ensured reliable token management and safer DeFi integrations, demonstrating depth in blockchain integration, smart contract development, and full stack engineering practices.

In October 2025, two key token-asset enhancements were delivered across Balancer token lists and customized token registries, expanding asset coverage and improving user experience on Base and AVA networks. These changes are designed to increase liquidity access, reduce onboarding friction, and improve token discoverability for end users and integrators.
