SWIFT or USDT on TRON: cost, timing and risks for paying a foreign supplier
An international bank transfer and USDT on the TRON network solve the same problem by different routes. This comparison lays out the cost components, timing and risks of each, using only public data, each with a source and date.

Key points
- SWIFT adds up the bank's fee, the exchange spread, IOF (Brazil's foreign exchange tax) and intermediary fees; USDT adds up the purchase quote, the network fee and the cost of converting on the other side.
- On Feb. 13, 2025, the network fee for a USDT transfer on TRON was about 13.5 TRX (roughly US$3.3) for a wallet that already holds USDT, and about 27.4 TRX for a new wallet.
- SWIFT follows banking rules and the business hours of the banks involved; the TRON network operates 24 hours, but a confirmed transfer cannot be reversed.
- The choice depends on what the supplier accepts to receive and on how the company documents the operation.
A Brazilian company that buys from a supplier in China, the United States or Europe has, in practice, two ways to pay: an international payment order through a bank, which uses the SWIFT messaging network, and the transfer of a stablecoin, such as USDT, over a blockchain network. This text compares the two by criteria the buyer can verify: cost components, timing, hours, traceability and risk. The numbers have a source and a date. The text does not rank or recommend either route.
How each route works
SWIFT does not move money: it transmits instructions between banks. The TRON network, on the other hand, records the transfer itself, which anyone can check through the transaction hash. To understand the network and the token, see what TRON and the TRC-20 standard are.
The total cost: what it is made of
The most common mistake is comparing only the fee. In both routes, most of the cost usually sits in the exchange quote, not in the explicit fee. For that reason, the right comparison uses the effective quote received on each route, measured against the reference dollar at the same moment.
| Component | SWIFT (bank) | USDT on TRON |
|---|---|---|
| Service fee | Charged by the bank; each institution publishes its own fee schedule, and the amount varies by channel and customer profile | There is no bank fee; intermediaries charge a fee or spread for the service, if any |
| Exchange spread | Built into the bank's quote; not published as a fee | Built into the quote for buying USDT in reais; varies by platform and moment |
| IOF | 0.38% on the exchange operation: this is the general rate in art. 15-B of Decree 6,306/2007, and import payments have no rate of their own | Buying USDT with reais in Brazil was not treated as an exchange operation, and no foreign exchange IOF was provided for it. The Central Bank of Brazil (BCB) had a proposal under public consultation (CP 111) to bring these payments into the foreign exchange market; confirm with your accountant |
| Network fee or intermediaries | Intermediary banks may deduct fees from the amount sent | About 13.5 TRX (wallet that already holds USDT) or 27.4 TRX (new wallet), paid in TRX |
| Cost on the supplier's side | Receiving fee charged by its bank | Conversion of USDT into local currency or direct use, depending on the supplier |
The TRON network fee depends on two parameters. A USDT transfer consumes about 64,000 units of energy when the recipient already holds a USDT balance, and about 130,000 when it is an address with no USDT, because the contract has to write a new record. With energy at 210 sun per unit, the calculation comes to approximately 13.5 TRX in the first case and 27.4 TRX in the second. On Feb. 12, 2025, TRX closed near US$0.243 on the TRX/USDT pair on Binance, which gives roughly US$3.3 and US$6.7. The calculation changes with the TRX price and with the price of energy, which the network's Super Representatives can change by vote.
The World Bank tracks the cost of US$200 remittances between individuals: the global average was 6.65% in the second quarter of 2024, the most recent data published as of this date. It is a market reference, not the price of a high-value business payment, where the fixed fee weighs less and the spread weighs more.
Timing, hours and traceability
| Criterion | SWIFT (bank) | USDT on TRON |
|---|---|---|
| Timing | Depends on the route and the banks. In 2024, 50.6% of wholesale payments over Swift were credited within one hour and 92% within one business day, according to the FSB | TRON produces a block every 3 seconds; a transfer is usually finalized in about a minute |
| Hours | Contracting during the bank's and the foreign exchange market's hours; each bank has a daily cutoff | 24 hours a day, every day |
| Traceability | gpi tracking code (UETR) when the banks participate; information comes from the banks | Public hash, verifiable by anyone on a block explorer |
| Reversal | A return can be requested, subject to the beneficiary's bank | A confirmed transfer cannot be reversed |
| Documentation | Exchange contract and documents required by the bank | The company needs to keep the invoice, receipt and hash; the BCB's rules for the flow were still under public consultation |
SWIFT timing is the item that depends most on the case. In its October 2024 indicators report, the Financial Stability Board (FSB) concluded that cross-border payments showed “limited progress” toward the G20 targets for cost and speed. The slowest stage remains the last one: the time the beneficiary's bank takes to credit the amount to the customer's account. SWIFT gpi improved traceability, but the route still determines the time.
Risks of each route
- USDT peg. The stablecoin is issued by a private company and has drifted from US$1 in moments of stress. Whoever sends and converts right away reduces the exposure.
- Irreversibility. A wrong or fraudulent address on the TRON network allows no reversal. Address poisoning is a documented scam; confirm the wallet through a second channel.
- Regulation. In February 2025, the Central Bank was still consulting the market on the rules for virtual asset providers, as the article on the BCB's public consultations shows. There is no guarantee from Brazil's deposit guarantee fund (FGC) on virtual assets.
- Acceptance. Not every supplier receives USDT, and there are regions where the token faces restrictions. In Europe, for example, MiCA changed the USDT offering.
- Bank and compliance. On SWIFT, the bank may ask for documents and hold the operation for review. This reduces risk but lengthens the timing.
How to compare in practice
Ask for two quotes for the same amount on the same day and compare three numbers: the total in reais leaving the account, the total in dollars arriving at the supplier and the time at which the supplier can use the funds. The difference between the reference dollar and the effective quote is the real cost. Add up fixed fees, IOF, network fee and the supplier's conversion cost. Only then compare.
- Define the amount and the currency the supplier needs to receive.
- Ask the bank for a quote with all fees and the expected credit date.
- Ask for the USDT quote in reais, the network fee and the supplier's wallet address, which must be confirmed through another channel.
- Calculate the effective cost of each route against the same dollar reference.
- Keep the invoice, exchange contract or receipt and, in the case of USDT, the transaction hash.
Frequently asked questions
How much does it cost to send USDT on the TRON network?
The network fee is paid in TRX and depends on the energy consumed. On Feb. 13, 2025, with energy at 210 sun, a transfer to a wallet that already held USDT cost about 13.5 TRX (roughly US$3.3), and to a wallet without USDT, about 27.4 TRX. This fee does not include the quote for buying USDT in reais.
How long does a SWIFT transfer take?
It depends on the route. According to the FSB, using Swift data, 50.6% of wholesale payments were credited to the end customer within one hour in 2024 and 92% within one business day. Intermediary banks, time zones and compliance reviews can lengthen the timing; the bank gives an estimate when the operation is contracted.
Is there IOF on paying a foreign supplier?
On Feb. 13, 2025, the general IOF rate on foreign exchange operations was 0.38% (art. 15-B of Decree 6,306/2007), and import payments had no specific rate. Buying USDT with reais in Brazil was not treated as an exchange operation. Because the treatment depends on the operation, confirm with the bank or your accountant.
Can a USDT transfer sent to the wrong wallet be reversed?
No. A transfer confirmed on the blockchain is irreversible, and only whoever controls the destination wallet can return it. For that reason, it is advisable to confirm the address through a second channel and to send a small test amount first.
