Quack AI launches x402 BNB, creating the first unified "sign-to-pay" layer for BNB Chain

ChainCatcher reported that Quack AI published an article on Medium announcing the launch of its new infrastructure, x402 BNB—the first unified Sign-to-Pay and governance layer based on BNB Chain, designed to provide a simplified and secure transaction experience for the on-chain Agent economy.

This system is built on the EIP-7702 delegated execution and EIP-712 signature standards, enabling authorization, transfer, and payment to be completed with a single signature, without the need to manually handle Gas or repeated confirmations. x402 BNB, developed by Quack AI, integrates a Gas sponsorship relay layer and a strategy governance module, supporting scenarios such as multi-address payments, automatic renewals, and DAO fund allocation.
