About

DeFiLlama is the go-to free source for decentralized finance data, tracking total value locked across protocols and chains, plus yields, stablecoin supplies, fees, and volumes. You can use it to rank DeFi protocols by size, to hunt for the highest stablecoin yields, or to watch how money moves between blockchains over time. The public API needs no key, which makes it ideal for dashboards and research notebooks.
