x402 from zero

BNB Chain

Binance’s chain, whose B402 copies Coinbase’s x402 v2 spec and sponsors gas; testnet, with mainnet on request.

Checked 11 October

Our view

B402 matches Coinbase’s v2 spec field for field, so a client built for Coinbase needs only a URL change, and Binance pays the gas. Its docs, modified 9 October, still showed testnet with mainnet by request, and no x402 volume had been found. The research did not score rivals; these labels are the site’s reading of the dated evidence.
