Developed and delivered the Sei TVL Calculator Module within the DefiLlama-Adapters repository, enabling accurate computation of Total Value Locked for the Sei blockchain by aggregating balances across specific token owners and addresses. This feature, implemented using JavaScript and backend development skills, established a scalable data path that supports future integrations with additional chains. The work focused on enhancing DeFi analytics by improving TVL coverage and dashboard visibility for Sei, laying the groundwork for more dependable on-chain valuations. All contributions were made in the context of the PredPred project, with changes tracked and documented through a dedicated feature commit.
