Stage one: the quote and its window
A quote is a promise with a timer. It is computed from a mid-market reference — the middle between global buy and sell prices — and adjusted by the spread and the service fee. From the moment you see it, it is only valid for a limited window: enough for a normally loaded transfer to confirm, not enough for the market to move meaningfully against it.
Why not lock it forever? Because between your confirmation and the network's final confirmation there is a gap, and during that gap the service carries the price risk. A window that is too generous would have to be paid for by a wider spread for everyone. The limited window is the honest compromise — and an expired quote is recalculated openly, not honoured secretly at a loss that then appears as a "delayed payout".
Stage two: the one-time address
Your request is issued an address from a pool that exists for exactly one purpose: this request. The address is not your account — it is not even "yours" — it is a mailbox with one letter expected. That is why reusing an address from an old request is a mistake: the mailbox is closed, and a letter dropped into it later has to be sorted by hand.
The second identification factor is the exact amount. Together, "which mailbox" and "how heavy is the letter" bind an incoming transfer to a request without any personal data. This design is what allows the service to work without collecting names or documents.
Stage three: on-chain confirmation
TRON confirms transfers quickly by design, and the fixed TRC20 transfer fee does not grow with the amount. But "quickly" is a distribution, not a guarantee: block production, network load and the wallet platform's own withdrawal queue all add their share. A transfer sent from a platform can sit in that platform's outgoing queue for a while before the chain even sees it.
A confirmed transfer in TRON is final. There is no recall, no chargeback, no "cancel" button — for anyone, including the sender. This finality is precisely what makes the next stage possible.
Stage four: matching and the fiat side
Once the transfer is confirmed and matched, the fiat leg is released: a bank transfer or wallet payout by the details confirmed in the request chat. This is the stage where external systems take over — banking hours, holidays, the receiving bank's own incoming-fee policy. No exchange service controls these; the honest ones say so instead of promising instant fiat.
The status of the request at each stage is visible, which converts waiting from anxiety into observation. When the payout is done, the request closes with its full record: the hash, the amounts, the quote and its timestamp.
What usually goes wrong (and whose problem it is)
Three mistakes cover most incidents: sending the wrong network or asset, sending a rounded amount, and sending to an old address. All three are on-chain facts — the coins exist — but none is matched automatically, so all three require the hash and a message to support to resolve manually.
The rest of the incident space belongs to the fiat side: delayed bank postings, currencies converted by the receiving bank, a payout sent to mistyped requisites that were confirmed in the chat. This is why the chat confirmation step exists: what was confirmed in writing is much easier to untangle than what was assumed.
Directions covered here
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 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 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.

Why is the quote window limited rather than indefinite?
Between confirmation and on-chain settlement the service carries the price risk. An unlimited lock would be paid for by a wider spread for everyone; a limited window with open recalculation is the honest structure.
Does the exchange see my personal data when I sell?
No identity documents are collected. The request is matched by a one-time address and an exact amount; incoming funds are screened by their blockchain history, not by your passport.
