Permit2 is a next-generation token approval and meta-transaction system that enables signature-based approvals and transfers for ERC20 tokens, even those without EIP-2612 support. It provides features like batched approvals and transfers, expiring permissions, and safe arbitrary data verification, making token interactions more secure and efficient. This project is designed for developers building decentralized applications who want to streamline token approval flows and enhance user experience while maintaining strong security standards.
