What BSC Supports

Exact Scheme (Permit2)

Standard x402 exact scheme via Uniswap Permit2. BSC stablecoins lack EIP-3009, so Permit2 is the settlement path. No BSC-specific code needed.

USDT + USDC (18 Decimals)

Both Binance-Peg stablecoins supported. 18 decimals (not 6). The facilitator handles decimal conversion automatically.

Gas Sponsored

Dexter pays BNB gas for every BSC settlement. Buyers only need stablecoins.
