Developed and delivered the Stone Vault TVL Adapter for the DefiLlama-Adapters repository, enabling accurate calculation of total value locked for yield-bearing tokens managed by the StoneVaultCore contract on Ethereum. This work expanded the platform’s coverage of yield-bearing assets and improved data modeling for DeFi analytics. The implementation, written in JavaScript and focused on backend development, included robust unit tests to ensure reliability and maintainability. By enhancing visibility into Stone Vault yields, the adapter supports downstream dashboards and analytics tools. No major bugs were reported during the development period, reflecting a careful and methodical engineering approach to DeFi infrastructure.
