What is USDT payment?

USDT payment is a transaction made using Tether (USDT), a stablecoin pegged to the US dollar. Because its value stays close to $1, USDT allows businesses and users to send and receive money without worrying about major price volatility common in other cryptocurrencies.

USDT payments are fast, cheap, and work across multiple blockchain networks like Tron, Ethereum, and Polygon. They’re popular for international transfers, e-commerce, trading platforms, and payouts because they settle quickly and don’t require banks or intermediaries.
