Api Endpoint

defiexec-build

Non-custodial yield deposit/redeem calldata for Base: give protocol (aave-v3, compound-v3 or erc4626), asset or vault, raw amount, action and recipient; we read the protocol on-chain state and return ready-to-sign transaction calldata plus the ERC-20 approval (deposit only) and the expected shares or assets. You sign with your own wallet — we never hold or move funds.
