TechFlow news, October 29 — Quack AI today announced the launch of x402 BNB, the first unified signature-based payment and governance layer solution on the BNB Chain. By integrating EIP-7702 delegation execution, EIP-712 witness signatures, and gas fee sponsorship relayer technology, the protocol simplifies the traditional multi-step process of "approve → transfer → pay" into a single verifiable signature operation.
Key features of x402 BNB include a one-step signing experience, modular development stack, secure design architecture, multi-asset support, and seamless compatibility. The protocol aims to provide secure, gasless, and accountable infrastructure for the Agent Economy, addressing pain points in liquidity operations on the BNB Chain. Quack AI stated that full specifications, smart contracts, and reference implementations will be released soon.
