Jinse Finance reported that Web3 payment and compliance infrastructure Pieverse announced on Twitter that it will launch the x402b protocol, extending the x402 protocol to BNB Chain using the Pieverse Facilitator, supporting EIP-3009 gas-free payments and auditable receipts. x402b addresses the gas-free issue by introducing pieUSD, allowing users to complete payments simply by signing a message; meanwhile, the custom Facilitator generates receipts compliant with judicial jurisdictions during payment settlement, which are immutably stored on BNB Greenfield.
