System Documentation

What problem does it solve?

Enables apps to authorize specific token transfers without on-chain pre-approvals by signing an EIP-712 permit (Permit2) that can be consumed by a contract.

Core Features & Use Cases

  • Gasless approvals: users sign one permit off-chain to authorize a swap, deposit, or withdraw action.
  • Witness binding: binds the signature to a specific action (e.g., tokenIn, tokenOut, vault, amount) via a witness.
  • SDK integration: leverages SignatureTransfer.getPermitData to construct domain, types, and values for on-chain verification and integration with permit2 contracts.

Quick Start

Sign a permit and witness for a targeted DeFi operation.
