The **permit2‑sdk** is a developer‑focused library that wraps the [Permit2](https://github.com/derpdex-official/permit2) smart‑contract system, providing TypeScript utilities, type‑safe contract interfaces, and testing helpers for generating and handling Permit2 signatures and approvals. It’s intended for blockchain engineers building dApps, DeFi protocols, or any Ethereum‑compatible project that wants to integrate gas‑less token approvals via Permit2 without writing low‑level calldata manually.
