Quack AI launches x402 BNB, creating the first unified "signature payment" layer for the BNB chain

ChainCatcher message, Quack AI has launched a new infrastructure x402 BNB, the first unified Sign to Pay (signature to payment) and governance layer based on BNB Chain, aimed at providing a simplified and secure transaction experience for the on-chain economy.

The system is based on the EIP-7702 delegated execution and EIP-712 signature standards, as well as a gas-sponsored relay layer, allowing authorization, transfer, and payment to be completed with a single signature, without the need to manually handle gas or confirm repeatedly. x402 BNB is developed by Quack AI, integrating a gas-sponsored relay layer and strategy governance module, supporting scenarios such as multi-address payments, automatic renewals, and DAO fund allocation.
