Notas de integración
Lo importante antes de producción
ERC20 works best for Ethereum-native customers
Use ERC20 when your customers already operate on Ethereum or when their wallets, exchanges, or accounting systems prefer Ethereum settlement.
Gas cost expectations should be clear
ERC20 transfers can be more expensive than TRC20 or BEP20, so your checkout copy should help customers choose the right network.
Transfer log monitoring is more reliable than manual balance checks
BoltUtil watches USDT Transfer events and matches the actual token movement to pending orders after confirmation.
