Developed and delivered a core feature for the DefiLlama/DefiLlama-Adapters repository, enabling calculation of Total Value Locked (TVL) for vaults on both Sui and Bitcoin. This work focused on backend development and API integration using JavaScript, introducing logic to aggregate and track assets across multiple blockchain protocols. By expanding vault coverage to include Sui and Bitcoin, the implementation allowed for unified analytics and cross-chain asset tracking within the platform. The approach emphasized robust data handling to ensure accurate TVL computation, supporting consolidated reporting for multi-chain vaults and enhancing the platform’s ability to monitor decentralized finance assets programmatically.
