The Blockdaemon DeFi API is a unified and standardized interface that enables seamless DeFi integration across 50+ blockchains and protocols. With an exhaustive set of endpoints covering key primitives like DEXs, bridges, and lending platforms, we connect developers, traders, wallets, institutions, and applications to the entire DeFi ecosystem.

Whether you need to perform same-chain token swaps, transfer assets across blockchains, or integrate lending and borrowing capabilities, Blockdaemon provides the tools to support a wide range of decentralized application workflows.
