Exchange directions
The deal patterns of the USDT market, direction by direction.
Sell USDT (TRC20) and get fiat on your card
You send USDT in the TRON network from any wallet you control, and the fiat side arrives on the card number you specified. The request is tied to a one-time receiving address and an exact amount, so no names or messages are needed to match the transfer.
Learn moreSell USDT and receive yuan (CNY)
The yuan direction has its own character: pricing is quoted per one USDT, the payout goes by bank transfer or a wallet in CNY, and the details are agreed in the chat of your request before anything moves on-chain.
Learn moreBuy USDT (TRC20) with fiat
Here the flow runs the other way: you declare the fiat you are paying with, agree on the amount of USDT at a locked quote, and receive the coins to a wallet address you control. The outgoing transfer is visible in the request with its hash before anything is considered done.
Learn moreVirtual cards funded with USDT
A virtual card gives your crypto balance a place to spend online: subscriptions, hosting, ads, digital purchases. The card lives in the GF-PAY interface, is topped up from your USDT balance and spends like a regular card in the networks it is issued for.

The wallet screen in GF-PAY answers one question — what has arrived and what is the balance now — and deliberately cannot answer another: how to move the funds. The private keys never reach the server; signing happens outside, where you keep your seed.
Learn moreReceiving payments on a pool of addresses
When many people need to pay you in USDT, the fragile part is telling their transfers apart. The pool approach gives every request its own receiving address and its own exact amount, so each incoming transfer identifies itself by where it landed and for how much.
Learn moreOTC: large amounts, individual terms
Above a certain size, a deal stops being a retail exchange and becomes a small project: the price is negotiated, the execution is split into steps, and every agreement lives in the request chat in writing. This direction exists for that scale.
