DeFi TVL & Yields
Protocol TVL, chain rankings, yield pools, and token prices across DeFi
DeFiLlama coverage: every tracked protocol with current and historical TVL, TVL by chain, and the full yield-pool set with APY and risk data. Token prices resolve by coin identifier, so a pipeline can price positions and rank protocols from one service.

Live 0x swap pricing, executable quotes, and gasless trading
