What problem does it solve?
Generate and validate Permit2 witness signatures for Balancer V3 router swaps to enable secure signed trades.
Core Features & Use Cases
- Canonical witness retrieval: Reads and uses the router-provided witness type string and hash.
- Typed-data signing: Enforces EIP-712 signing for witness payloads, preventing unsafe signing methods.
- Nonce/deadline handling: Generates fresh nonces and enforces strict expiry to prevent replay.
Quick Start
Configure and call the signed swap path using the router's Permit2 witness to authorize a Balancer V3 trade.
