Our endpoints make it easy to craft a great DeFi experience in your platform.

Integrate our API once, get access to hundreds of vaults across 10+ chains. We reduce complexity for your team by giving you a unified interface for interacting with leading DeFi protocols.

Key Benefits

    • (supply / withdraw / claim transactions) Generate payloads and calldata for function calls to vault smart contracts. We prepare transactions for simulation and signing.

    • Call our endpoint to understand how to supply/deposit and withdraw/redeem for any vault we cover.

  • Non-custodial. No intermediary smart contracts.

    • The vaults.fyi API is entirely non-custodial, preserving users' autonomy and security.
