Announcing x402b: We're using Pieverse Facilitator to extend x402 for
@BNBCHAIN with EIP-3009 gasless payments and auditable receipts.
The x402 protocol is a powerful standard for HTTP web payments, but two gaps are holding back its adoption on BNB Chain.
x402b bridges those gaps.
1. The Gasless Problem: x402 was designed for gasless payments via EIP-3009. The problem? Major stablecoins on BNB Chain—like USDT—don't support it.
Our Solution: We're introducing pieUSD, a 1:1 USDT wrapper that adds EIP-3009 support. This unlocks the true, native gasless experience of x402 on BNB. Customers just sign a message—no gas required.
2. The Audit & Tax Problem: Businesses and professional individuals need traceable and verifiable paper trails for tax and audit purposes. The x402 spec doesn't have a standard for this.
Our custom Facilitator solves this by automatically generating jurisdiction-compliant receipts during payment settlement, storing them immutably on BNB Greenfield.
With x402b,
@BNBCHAIN gets the first complete, enterprise-ready HTTP payment protocol.
Full protocol spec, smart contracts, and our reference implementation are dropping soon.
