Today, we are proud to launch x402 BNB, developed by @QuackAI_AI.
This is the first unified signature payment and governance layer in the @BNBCHAIN proxy economy.
x402 BNB is based on a relay layer using EIP-7702 delegated execution, EIP-712 witnessed signatures, and gas sponsorship.
It replaces all manual approval → transfer → payment steps with a single verifiable signature.
BNB Chain doesn't lack liquidity, but rather a unified way to transfer liquidity. Most tokens still rely on outdated processes that create friction and limit scalability.
x402 BNB solves this problem at the protocol level, enabling one-click, gas-free transactions that are verifiable, auditable, and policy-compliant.
Key Highlights:
1. Single Signature Experience: Users only need to sign once; gas fees are processed in the background.
2. Modular Developer Stack: Delegated execution, gas sponsorship, and governance interfaces.
3. Security Design: Whitelisted targets, double nonce, expiration enforcement, and metadata binding.
4. Multi-Asset Support: Batch transfers, split settlements, and automated proxy payments.
5. Seamless Compatibility: Works with the BNB mainnet, EIP-7702 network, and ERC-4337 payment master.
x402 BNB is the foundation of Governed AgentFi, creating a secure, gas-free, and traceable track for the agent economy.
Full specifications, smart contracts, and reference implementations are coming soon.
