What Is a USDT Payment Gateway?
A USDT payment gateway enables your platform to receive payments in USDT. It acts as a bridge between your application and the blockchain network, allowing users to pay in stablecoin while ensuring you receive accurate, real-time notifications of every transaction.
Key features include:
- Instant payment verification
- Multi-chain compatibility (TRC20, ERC20, BEP20)
- Secure wallet integration
- Transaction tracking and dashboards
Some gateways (like XAIGATE) also provide fiat settlement, multi-chain support, and analytics dashboards.

Here are key benefits of integrating a USDT payment gateway:
- Stability: Unlike BTC or ETH, USDT is pegged 1:1 to USD

- Faster Transactions: Finality within seconds
- Global Reach: No need for bank accounts or fiat rails
- Privacy: No credit card or personal info required from customers
