Today, we’re introducing x402 BNB.
The first unified sign-to-pay and governance layer for the Agent Economy on @BNBCHAIN
Powered by EIP-7702 delegated execution, EIP-712 witness signatures, and a gas-sponsored relayer layer,
x402 BNB replaces every manual approve → transfer → pay step with one verifiable signature.
BNB Chain doesn’t lack liquidity, it lacks a unified way to move it. Most tokens still rely on outdated flows that create friction and limit scalability.
x402 BNB fixes this at the protocol level, enabling one-click, gasless transactions that are verifiable, auditable, and policy-aware.
Key Highlights:
1. One Signature Experience: Users sign once, gas is handled in the background.
2. Modular Developer Stack: Delegated execution, sponsored fees, and governance hooks.
3. Secure by Design: Whitelisted targets, dual nonces, expiry enforcement, and metadata binding.
4. Multi-Asset Ready: Batch transfers, split settlements, and automated agent payouts.
5. Seamless Compatibility: Works with BNB mainnet, EIP-7702 networks, and ERC-4337 Paymasters.
x402 BNB is the foundation for Governed AgentFi, creating safe, gasless, and accountable rails for the Agent Economy.
Full spec, smart contracts, and our reference implementation are dropping soon.
