Learn to operate with REXUS
Short videos, step-by-step guides and straight answers for whoever operates for the company: buying, selling, paying bills and keeping every transaction safe. If anything is still unclear, talk to us.
Videos
Video tutorials
The official series explains the platform in a few minutes: what it is, how it works in practice and the step by step of each transaction. The episodes are narrated in Portuguese and show up here as they are published.
How it works in practice
The three steps of a buy, with the full breakdown on screen before you pay: the quote locked for 30 minutes and the crypto going straight to your wallet.
REXUS or a traditional exchange?
What changes between a platform that coordinates the transaction and an exchange that holds your balance: custody, pricing, cost and who each model is for.
Your first transaction
The full tutorial, from sign-up to the receipt: creating the account, the care with asset, network and address — which cannot be undone — the PIX and tracking the order to the transaction hash.
How to sell and receive the PIX
The way back: the PIX key on your account, why the quote does not lock on a sell as it does on a buy, sending the crypto, and what happens if less arrives than the order declared.
How support works
Where to open a ticket inside the app, why pointing to the related order changes the answer, and what business-hours support is — and what it is not.
How the commission system works
The affiliate program from the inside: where the 1% pool comes from, why only a completed transaction pays, the four network levels, the 2× multiplier and when withdrawals unlock.

Questions
Frequently asked support questions
The situations that come up the most in support tickets. Questions about coins, networks, fees and limits are in the frequently asked questions on the home page.
I paid the PIX and the crypto has not arrived. What should I do?
Open the order under Orders in the app: the screen shows which stage it is in. Once the PIX is confirmed, the transfer is queued and usually arrives within minutes, depending on the network. If it takes longer than that, or if the order is under review, open a ticket under Support and link that order — the team replies with the status.
I used the wrong network or wallet address. Can it be undone?
Blockchain transactions are irreversible, so check the network and the address before confirming. While the order has not been paid (buy) or the crypto has not been sent (sell), you can cancel it and start again with the right details. After the transfer there is no way to reverse it.
What does "under review" mean and how long does it take?
It means the order was held for the team to check before proceeding — an amount above the automatic limit, a large first transaction, a duplicate, or a payment outside the deadline. You are notified in the app, and the order always ends up either approved or refunded: nothing is held without an answer.
How do I change the PIX key that receives the money from a sell?
In the app, under Profile, you can change the PIX key whenever you want: CPF, CNPJ, email, phone or random key. The first sell with a new key goes through a security check before the payment.
I forgot my password. How do I get back in?
On the sign-in screen, tap "Forgot my password" and enter the email on your account. You get a link to set a new password. The link is valid for a limited time; if it expires, request another one on the same screen.
Do I need to install an app from the store?
No. REXUS opens in the browser and, if you like, can be added to your home screen to be used as an app, with no app store involved. The step by step for Android and iPhone is under "An app for your team" on the home page.
What are the support hours?
Tickets opened under Support in the app are answered during business hours; the current hours are shown on the Support screen itself. For company matters outside the app, email [email protected].
Contact
Talk to a person
For anything about the company account or its orders, use a ticket in the app: that is where the team can see the transaction and answer you safely.
Ticket in the app
The official channel. You open the ticket, link it to a specific order and follow the answer inside the app, with the history saved.
Open a ticketContact email
For company onboarding, documents and commercial matters. Never send passwords, verification codes or private keys by email.
Desk for high volume
Company transactions above R$ 100,000 get a negotiated fee. Email our desk ([email protected]) and get a tailored offer.
Talk to the deskHeads up. The REXUS team never asks for your password, verification code or wallet private key, and does not provide support by phone or direct message. Any contact outside a ticket in the app asking for those details is a scam attempt.
