Blockdaemon

Blockdaemon DeFi API

Single REST interface (formerly Expand Network) into multiple DeFi protocols — DEX swaps and aggregation across 200+ DEXs, cross-chain bridge swaps and aggregation, and lending/borrowing on Aave V2/V3 and Compound V2/V3. Supports same-chain and cross-chain swaps, configurable slippage, EIP-5792/EIP-7702 transaction batching, and combined approval+swap calls.
