Worked on expanding cross-chain capabilities within the DefiLlama-Adapters repository by implementing a multi-chain configuration for the Alphix adapter. Focused on integrating Arbitrum support alongside the existing Base chain, the work involved refactoring the adapter to a scalable multi-chain pattern, simplifying future additions. Leveraged JavaScript and Node.js to introduce Arbitrum-specific subgraphs and hooks, enabling seamless cross-chain querying and liquidity management. The approach enhanced liquidity reach and resilience by allowing users to manage assets across multiple chains through a unified interface. Emphasized API integration and full stack development to ensure robust, maintainable code that supports evolving DeFi infrastructure requirements.
