Swap Bitcoin for USDT on TRON without an account: enter the amount, paste your T… address and send BTC from any wallet.
TRX (or rented energy)You hold bitcoin and need dollars that move instantly and cheaply: an invoice in USDT, a counterparty who wants a T… address, or a pause out of the price while you decide what next. USDT on TRON is the most widely accepted form of USDT, and TRON fees are small, which is why this is the default route for cashing part of a bitcoin position into a stable balance.
A Bitcoin wallet cannot pay a T… address, and no TRON contract can see a bitcoin payment. The route receives your BTC at a one-time address, waits for 2 confirmations — plan for 21–44 minutes — and then transfers USDT on TRON to the address you gave. Most of the wait is Bitcoin block time, and the USDT amount is fixed only when the second confirmation arrives.
 BTC on Bitcoin |  USDT on TRONTRC-20 | |
|---|---|---|
| Address format | 1…, 3…, bc1… | T… (34 characters) |
| Fee token | BTC | TRX (or rented energy) |
| Confirmations we wait for | 2 | 1 |
| Explorer | blockchain.com | tronscan.org |
Paste your TRON address, the 34-character string starting with T, where the USDT should land. The estimate is in USDT and follows the BTC price.
You get a one-time Bitcoin address. Send the exact amount in one transaction, with a fee your wallet expects to confirm within the next few blocks.
2 confirmations. Blocks average ten minutes but vary; plan for 21–44 minutes. The USDT amount is fixed at the second confirmation.
The status page links your deposit on the Bitcoin explorer and the Tronscan transaction that credits your T… address. TRON confirms it in seconds.
A transaction that waits hours for a block is a swap whose rate is set hours later than you planned. In a moving market the USDT figure can end up noticeably different from the estimate. Pay a fee that confirms in the next block or two; if the wallet can raise the fee of a stuck transaction, use that rather than sending again.
The USDT figure on the form is what the market offers at that second. Between your send and the second Bitcoin confirmation, 21–44 minutes pass. If BTC moves 1 % in that time, so does the payout. This is what a floating rate means; the status page shows the final figure the moment it is fixed.
| Way | What you need | Where it is slower or dearer |
|---|---|---|
| An exchange account | An account; a BTC deposit with the exchange's own confirmation count, a market sell, a TRC-20 withdrawal | Sign-up, a trading fee, a withdrawal fee, and usually more confirmations than two |
| A peer-to-peer trade | A buyer with USDT on TRON, escrow or trust, time | A negotiated price and the counterparty's schedule |
| This swap | Two addresses | A floating rate fixed at the second Bitcoin confirmation |
Your bitcoin transaction is public and permanent: the explorer shows the inputs you spent, the deposit address, the amount and the fee. Tronscan shows a USDT transfer from a payout address to your T… address with the amount and the time. The two records sit on unrelated chains; only the status page, which you hold, pairs them.
About 21–44 minutes: 2 Bitcoin confirmations plus processing. A slow block or a congested mempool can stretch it. The TRON payout itself takes seconds.
A single block can still be replaced by a competing one. Two make a reversal impractical for the amounts a swap handles, and USDT once sent cannot be taken back.
Any — legacy 1…, P2SH 3…, SegWit bc1q… or Taproot bc1p…. The deposit address is chosen by us; your wallet only has to be able to send to it.
No. Receiving a TRC-20 transfer costs nothing. You need TRX or energy to move the USDT on.
It is shown under the amount field and follows the Bitcoin fee market: on a congested day it is higher.
Write to support with the swap ID from the status page. The form has no refund address: a swap that cannot be completed is handled by hand, and a return to the address you sent from is arranged under the partner's rules, less the network fee.
