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.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.
