Chencheng Alex worked on the DefiLlama-Adapters repository, delivering two core features over two months focused on blockchain integration and backend development. He implemented MANTA token support by aligning API calls with the vToken2 parameter, improving token data accuracy and streamlining the codebase by removing unused Filecoin functionality. In the following month, he expanded asset coverage by adding Bifrost vETH 3.0 support, integrating staking and DEX APIs with existing liquidity pools to enable seamless vETH trading and staking. His work, primarily in JavaScript and Node.js, emphasized API development, code refactoring, and repository hygiene, resulting in more reliable and maintainable systems.

December 2025: Expanded DefiLlama-Adapters with Bifrost vETH 3.0 support, enabling seamless data access for vETH staking and trading. Implemented integration with existing liquidity pools to support vETH liquidity and on-chain activity in the DEX APIs. All changes delivered in a single commit, 8130cea855e32e77e3b859498ceebb75abefc0e0 (#17462).
