Key points
- Buying USDT to pay a supplier goes through four routes: trading directly with another person (P2P), using an exchange, hiring an OTC desk, or using an intermediary that delivers the USDT to the supplier's wallet.
- The routes differ in who the counterparty is, how much identity verification applies and who bears each risk. This comparison only describes criteria and risks, with no ranking among them.
- Since February 2, 2026, BCB Resolution 521 treats international payments with virtual assets as foreign exchange operations, and the Resolution 520 deadline for providers to apply for authorization ends on October 30.
- In P2P, the biggest risk usually sits with Pix: a fraudulent refund request, a third-party account and the freezing of the recipient's account.
A Brazilian company that needs to pay a supplier abroad with USDT faces a decision before the first transfer: where to buy the digital dollar. The question looks like one about price, but it also weighs on paperwork, on who answers if something goes wrong and on how the payment will be explained to the accountant and the bank. This comparison describes the four most common routes, using public data and the regulatory situation as of August 4, 2026.
What has changed in the rules since February
On November 10, 2025, the Central Bank of Brazil (BCB) published BCB Resolutions 519, 520 and 521. They took effect on February 2, 2026, and the remainder of Resolution 521, tied to transaction reporting, took effect on May 4. Resolution 521 brings international payments or transfers made with virtual assets into the foreign exchange market. When the counterparty is not an institution authorized to operate in foreign exchange, the text caps the operation at the equivalent of US$100,000 (art. 29, IV, of BCB Resolution 277, as amended by 521).
The same rule requires the provider to identify the owner of a self-custodied wallet, one whose owner controls the private key, and to keep documented processes for checking the origin and destination of the assets (art. 76-A, § 5, of BCB Resolution 277). The details are in what BCB Resolution 521 changes for stablecoin foreign exchange.
The deadline for companies already operating to apply for authorization from the Central Bank runs until October 30, 2026. Before sending money, check the regulatory status the company discloses on its own page, and be wary of anyone who does not state it.
The four routes, side by side
| Criterion | P2P | Exchange | OTC desk | Intermediary |
|---|---|---|---|---|
| Who the counterparty is | The person or company posting the offer | The exchange itself or other users | The desk | The intermediary acts on the client's behalf; liquidity comes from third parties |
| Identity registration | Varies: the platform asks, the advertiser does not always | Mandatory | Mandatory, usually with a business review | Mandatory, with the beneficiary's details |
| Where the cost is | Price difference in the offer and, on some platforms, a fee | Trading fee, spread and network withdrawal fee | Negotiated spread | Intermediation fee and network fee |
| Main risk | Disputed Pix, third-party account, fake receipt | Balance concentrated on the platform, rule changes | Counterparty and settlement time | Choosing a provider that neither explains its fee nor delivers the hash |
| Receipt for accounting | Platform and bank statements | Exchange statements and tax reports | Trade ticket for the operation | Receipt with amounts and transaction hash |
The risks of P2P, which run through Pix
Brazilian P2P revolves around Pix. A survey by Crystal Intelligence of 1,641 listings in Brazil, published by BlockTrends on February 18, 2026, found Pix in 80% of offers and USDT in 46.2%. Speed is the advantage, but Pix settles instantly and leaves room for fraud by people who dispute the payment afterward.
The Special Refund Mechanism (MED) allows a request to freeze funds for fraud or scams within 80 days of the transaction. Since February 2, 2026, MED 2.0 tracks the money beyond the first account, according to Forbes Brasil. The bank, however, does not guarantee a refund. For someone who sold USDT, the result can be USDT already delivered and the Pix frozen.
- A receipt is not a balance. Sellers should release the asset only after seeing the credit on the bank statement, and buyers should keep the chat and the receipt.
- Third-party Pix. If the payment does not come from the registered holder's account, the advertiser may be using a borrowed account, a so-called "laranja" account (a straw account). Receiving funds of illicit origin can lead to account freezes and liability.
- Off-market price. A quote well below the market rate is a classic sign of a scam.
- Conversation outside the platform. Agreeing on payment by message removes the escrow that protects both parties.
Exchange, OTC desk and intermediary: what to look at
On an exchange, the point of attention is the account. The reais deposit, the balance and the withdrawal all fall under the platform's rules. Anyone sending USDT to an external wallet has to answer a form on origin and destination, because the provider must identify the wallet's owner. For paying a supplier, that means stating who the beneficiary is and the purpose.
At an OTC desk, the minimum amount is usually higher and the price is negotiated. The central risk is counterparty risk: confirm who delivers the USDT, by when and with which document. It is worth asking for the contract or trade ticket in writing.
An intermediary reduces what the client has to do, since the client pays in reais and provides the supplier's wallet, but it adds a third party to the chain. The useful question is a direct one: does the company show the fee before confirmation, deliver the hash and offer support through a human channel? It is also worth asking which regime the company belongs to: BCB Resolution 561, published on April 30, 2026, prevents eFX international payment service providers from settling with virtual assets. According to Cointelegraph, the rule applies within the eFX channel and is not a general ban on crypto transfers. The hash of any transfer can be checked on a public explorer, such as Tronscan.
How to decide with your own criteria
Each route combines cost, requirements and risk in its own way. The choice depends on the amount, the frequency and how much the company wants to document. Four questions organize the decision:
- Who is the counterparty and what is its status with the Central Bank? As of August 2026, the deadline to apply for authorization is still open.
- Is the total cost clear before confirmation? Add up the fee, spread, network fee and IOF (Brazil's tax on financial operations), when applicable. The comparison bank, brokerage, global account or USDT shows the full calculation.
- Is there supporting documentation? Invoice, order or contract, beneficiary details and a receipt with the hash. The accountant and the bank will ask for them.
- Has the supplier's wallet been validated? Check it through a second channel and make a test transaction, as the guide on how to validate the supplier's TRC-20 wallet explains.
Virtual assets are not covered by the FGC (Brazil's deposit guarantee fund), USDT can lose its peg to the dollar, and a transfer confirmed on the blockchain is irreversible. A wrong wallet cannot be undone.
For those operating without a provider in the middle, Brazil's Federal Revenue Service (Receita Federal) has also changed the game. Normative Instruction RFB 2,291/2025, which created DeCripto, has applied since July 1, 2026 and requires anyone operating outside a Brazilian provider to report transactions above R$35,000 a month, as explained in the article on Receita Federal's DeCripto. Confirm the classification with your accountant.
Frequently asked questions
Is buying USDT through P2P legal in Brazil?
Buying and selling virtual assets between individuals is not prohibited, but BCB Resolution 521 brings international transfers with virtual assets, and transfers to or from a self-custodied wallet made by a provider, into the foreign exchange market. In practice, anyone operating without an identified provider faces a greater risk of account freezes and questioning. Ask your accountant for guidance.
What is the limit for paying a supplier abroad with USDT?
When the counterparty is not an institution authorized to operate in the foreign exchange market, BCB Resolution 277, as amended by 521, caps international payments or transfers with virtual assets at the equivalent of US$100,000. The rule applies to virtual asset service providers.
What is an OTC desk?
OTC (over the counter) is a direct trading desk, outside the exchanges' order book. It usually serves larger amounts, with a negotiated price and agreed settlement. The desk is either the counterparty to the operation or connects the client to third-party liquidity.
Can I ask for a refund of a Pix made in a P2P trade?
The MED allows a request to freeze funds for fraud or scams within 80 days, but it does not apply to a change of mind and does not guarantee a refund. If the seller has already released the USDT and the Pix is disputed, the dispute becomes a problem between the parties and the banks.
