A crypto transfer cannot be reversed: if the funds go to someone else's address, getting them back is almost impossible. A wrong address is one of the most common causes of losses, and scammers have learned to swap addresses in ways that are easy to miss. Here is how to check an address in a couple of minutes before you send.

What addresses look like on different networks

Bitcoin: starts with bc1, 1 or 3. Addresses like bc1q… and bc1p… are the modern SegWit and Taproot formats.
Ethereum and ERC-20 tokens: 0x followed by 40 characters — digits and the letters a to f.
TRON (USDT TRC-20): a capital T, 34 characters in total.
TON: 48 characters, usually starting with UQ or EQ.

The address format is your first filter. If the order uses the TRC-20 network but the address starts with 0x, something is wrong: stop and double-check.

The main rule: copy, don't type

Always copy the address from a reliable source — the order page or your own wallet — and paste it rather than retyping it by hand. A single wrong character usually makes an address invalid, but you should never rely on that.

Check the beginning, the end — and the middle

After pasting, compare the first 4–6 and last 4–6 characters with the original. For a large amount, check the entire address in blocks of a few characters. The next scheme explains why a quick glance is not enough.

Address poisoning in your transaction history

A scammer generates an address whose first and last characters match an address you have recently used, and sends a zero or tiny amount to your wallet. A look-alike address appears in your transaction history. The plan is simple: next time you copy the address from your history — and send your money to the scammer. This is known as address poisoning.

Never copy a recipient's address from your transaction history.
Ignore unexpected tiny deposits from unknown addresses and do not interact with them.
For regular recipients, use your wallet's address book, with addresses added from a reliable source.

Malware that swaps addresses in the clipboard

Some malicious programs monitor the clipboard and replace a copied crypto address with their own: you copy the correct address, but a different one gets pasted. The defence is simple: always compare the pasted address with the original, keep your system and antivirus up to date, and never install software from untrusted sources.

Network and comment

Make sure the network selected in your wallet matches the network in the order: “USDT” in a wallet can be sent over different networks.
If the order page shows a comment (memo, tag), add it: without it the transfer may not be credited automatically.

Should you make a test transfer?

Sending a small amount to your own new wallet or to an address you have not used before is a good habit. But you should not do this when paying for an order: an order is paid with one transaction for the full amount, and several transfers instead of one will only complicate processing. Instead of a test payment, carefully check the address, the network and the amount.

Where to get our payment details

Payment details for a Brothers Exchange order are shown only on the order page and in the order confirmation email. If you receive “other payment details” in a messenger or by email and they differ from those on the order page, do not transfer anything and contact support right away through the official contacts.

If you are receiving crypto under an order, check your own wallet address just as carefully before creating the order: the payout is sent to the address specified in the order.

Pre-send checklist

The address was copied from the order page, not from your transaction history or a chat.
The address format matches the network.
The first and last characters match the original.
The network in your wallet matches the network in the order.
The comment (memo) has been added, if one is shown.
The amount matches the order amount and is sent in a single transaction.
