PANews reported on October 29th that Quack AI published an article on Medium announcing the launch of its new infrastructure, x402 BNB—the first unified Sign-to-Pay (Sign-to-Pay) and governance layer based on the BNB Chain, designed to provide a simplified and secure transaction experience for the on-chain agent economy. This system is based on the EIP-7702 delegated execution and EIP-712 signature standards, enabling authorization, transfers, and payments to be completed with a single signature, eliminating the need for manual gas processing or duplicate confirmations.

Developed by Quack AI, the x402 BNB integrates a Gas-sponsored relay layer and a policy governance module, supporting scenarios such as multi-address payments, automatic renewals, and DAO fund allocation.
