- 3Send USDT or USDC—~45s
- 4The PIX goes out for the exact amount—~52s
Demo with sample values and accelerated time (illustrative rate of R$ 5,20 per USDT and a 2,5% fee). Actual time depends on the transfer being confirmed on the blockchain; on fast networks like Polygon it usually takes under a minute.
Static PIX QR codes, PIX keys (CPF, CNPJ, email, phone or random key) and "copy-and-paste" codes without a link. The recipient gets the full bill amount; the flat fee is added to what the company sends.
Dynamic QR codes (invoices with a due date) and boletos are not supported yet.
Pay a billWhen paying a bill, the PIX key can belong to someone else: the company pays a supplier, the office rent or a contractor's invoice directly with crypto. Sells work differently: the money goes back to the company's PIX key.
Payments above the platform's limit are reviewed before going out, and the company follows the status in real time.
One fee, no spread, no surprises.

2,5%*per transaction
Flat on every buy and sell. No hidden charges. The network (gas) fee on buys is estimated and shown before the company confirms.

Built so your company's money never gets stuck in between.
Sell and refund payouts go to the PIX key registered by the company. The key is checked before the transaction is confirmed.
Nothing sits on the platform. Every transaction goes in and out in one flow: PIX becomes USDT or USDC in the company wallet, or crypto becomes PIX in the company account.
Large amounts, a first transaction above the limit and unusual patterns are reviewed before proceeding. The company follows the status in real time.
PIX and crypto transfers are processed by a regulated partner payment institution with its own settlement.
The rate refreshes every 30 seconds. If it goes stale, the platform blocks new orders until it recovers.
Each account is tied to a valid CNPJ and an identified legal representative. That protects the company and stops others from transacting in its name.
Connect the company wallet: OKX Wallet or MetaMask.
Buy and sell straight from the wallet, with no address copying and no wrong network. On a phone, the connection opens the wallet app for approval.

- OKX WalletPolygon · ERC-20 · TRC-20
As soon as the wallet is connected, the app shows the USDT and USDC balance on each network.
When buying, the destination address is already filled in with the connected wallet, on the chosen network.
When selling, the app prepares the transfer of the exact amount and you just approve it in the wallet. The PIX goes to the company key.

Frequently asked questions
Who can open an account with REXUS?
Businesses with an active CNPJ in Brazil. The account is opened in the company's name, with its CNPJ details and the identification of the legal representative, who is responsible for the access of anyone operating on the company's behalf.
Which assets can the company buy and sell?
USDT (Tether) and USDC (USD Coin). Both are stablecoins: crypto assets designed to stay pegged to the US dollar, used to hold or move dollar value on blockchains. The asset is chosen in the simulator and in the app; each has its own rate.
Which networks are supported?
Polygon (default, cheapest), TRC-20 (Tron) and ERC-20 (Ethereum), subject to availability. USDT works on all of them; USDC on Polygon and ERC-20 (TRC-20 supports USDT only). The current list, with minimums and estimated network fee per asset, is shown in the simulator and in the app.
Can I connect the company wallet (OKX Wallet or MetaMask)?
Yes. Tap Connect in the app and choose OKX Wallet or MetaMask. On a computer, the connection uses the wallet extension; on a phone, the wallet app opens for approval and you come back to REXUS already connected. With the wallet connected, the balance shows up on its own, purchases go straight to it and sales are sent with one approval. Polygon and ERC-20 work with both; TRC-20 (USDT), with OKX Wallet.
How long does it take?
On a buy, the crypto is sent as soon as the PIX is confirmed and reaches your wallet within minutes, depending on the network. On a sell, the PIX goes out right after the crypto is confirmed on the blockchain. Transactions under review may take longer.
Which account receives the PIX from a sell?
To the PIX key registered by the company (CNPJ, email, phone or random key). The key can be changed in the profile; the first sell with a new key goes through a security check.
What does "under review" mean?
That the transaction was held for the team to review before proceeding, for example an amount above the automatic limit, a large first transaction, a duplicate, or a payment after the deadline. The company is notified in the app, and the money is never held without an answer: the order is either approved or refunded.
Can I cancel a transaction?
Yes, as long as it has not been paid yet (buy) or the crypto has not been sent yet (sell). After that, the transaction follows the normal flow or, if rejected in review, is refunded to the company.
What are the limits?
There is a minimum and a maximum per transaction and a daily limit per account, set by the platform and shown in the app. Each network also has a minimum per asset (USDT and USDC). Transactions above the automatic limit go through review; for larger volumes, talk to our desk.
Can I pay a boleto?
Not yet. For now we pay PIX: static QR codes, PIX keys (CPF, CNPJ, email, phone or random key) and "copy-and-paste" codes without a link. Dynamic QR codes with a due date and bank boletos are not supported in this version. The recipient gets the exact bill amount; the company sends USDT or USDC with the flat fee already included.
How do I contact support?
In the app, under Support, you open a ticket and can link it to a specific order. For other company matters, write to [email protected].
