It’s been a busy week — but the outcome is a game changer for x402 on @BNBCHAIN.
Meet USD402, the first native wrapper that brings $USDT, $USDC, and USD1 into the x402 ecosystem, seamlessly. ⚡️

Here’s why it matters 🧵👇

x402 expects tokens using EIP-3009 (transferWithAuthorization), but most stablecoins on @BNBCHAIN only support EIP-2612 (permit).
That mismatch made gasless payments difficult, until now. 👇
USD402 acts as a compatibility layer, wrapping $USDT, $USDC, and USD1 to make them x402-ready without needing any custom modifications.
Facilitators and users can now transact, mint, and settle using familiar stablecoins, natively.
This unlocks the full power of x402 on @BNBCHAIN:
- Gasless payments across APIs and agents,
- Stable, unified settlement in trusted assets,
- Compatibility for every facilitator and developer building the next generation of payment infrastructure
USD402 is the first step toward a universal, open payment layer on @BNBCHAIN that anyone can use. ⚡️
To all the builders out there 👇
