How to check a crypto exchanger before you swap: 9 checks
Check a crypto exchanger before you pay: verify the domain, reviews, direction terms, AML/KYC rules and order details, then watch for the red flags that mean walk away.
To check a crypto exchanger before a swap, confirm the site address, track record, direction terms, AML/KYC rules and order details before money leaves your card or wallet. That way you avoid phishing clones, held payments and payouts that never arrive.
OnExchanger.com is an exchanger monitor: it compares offers by rate, amount, limits and reserve and sends you to the exchanger. It holds no funds and performs no exchanges; the order, its terms, AML/KYC and support are the exchanger's. OnExchanger may earn a partner commission; you pay the exchanger's rate, nothing on top.
Why check an exchanger if the rate looks fine?
The rate shows the price, not whether the money will reach you. The real risks are a fake site, an AML hold, a thin reserve or the wrong network, so check an exchanger hardest when it is new to you.
The table sums up how to check an exchanger in nine steps.
| Check | Why it matters | Where to look |
|---|---|---|
| Site address | Clones change one letter or the domain zone | Address bar, monitor page |
| Track record | Shows how disputes end | Its site, review platforms |
| Direction terms | Decide what you receive | Rules, order form |
| Reserve and hours | Reserve must cover your amount; manual payouts follow working hours | Direction page |
| AML/KYC | A payment can be held for review | AML/KYC policy |
| Order details | Address, network and memo must match | Your order |
| First amount | A small swap limits the risk | Your plan |
| Red flags | They point to a scam | Support, "managers" |
| Delay plan | Order number and TXID speed up support | Exchanger's support |
Each row covers a different failure, so check exchangers against the whole list.
How do you check an exchanger's address and spot a clone?
Open the site from a place you trust, such as its page on a monitor, and compare the domain letter by letter. Phishing clones copy the design but change one letter or the domain zone.
When checking an exchanger's domain, look for doubled or swapped letters and extra hyphens, and ignore ads or messages promising a better rate. Each of the crypto exchangers OnExchanger tracks has a page that works as a safe starting point to check an exchanger and reach its real site.
How do you check a crypto exchanger's track record?
To check an exchanger's history, find the start year, contacts, terms of service and AML/KYC policy on its site, then read independent reviews on several platforms.
Recent negative reviews show where things break and how support replies. If you check an exchanger and find no contacts or rules at all, keep digging with extra suspicion.
How do you check an exchanger's terms before creating an order?
The direction's rules and the order form set the rate type, limits, fee, payment window and reserve, so read them before paying.
Three points deserve a close look:
- Fixed or floating rate. Is the rate locked when the order is created, or can it move while your transfer travels?
- Limits and fee. Your amount must fit between the minimum and maximum.
- Payment window. Learn what happens if you pay late or send a different amount.
When checking an exchanger's reserve, make sure it covers your amount; for manual payouts, note the working hours. For a market reference, see the USDT to hryvnia rate now; the crypto and USDT network pages show where to swap each coin.
Why can an exchanger hold your payment for AML/KYC?
Many exchangers screen incoming crypto with AML tools and may ask you to verify your identity or the source of funds, holding the payment until the review is done.
When you check an exchanger on this point, look for a clear AML/KYC policy and read it before sending. If you pay by card, the holder's name may need to match the client's details.
How do you send funds to an exchanger order safely?
Send only to the address in the order you created, on exactly the network it names. Add a memo if asked, and keep the order number, a screenshot and the transaction hash (TXID).
Skip none of these steps:
- Match the network. USDT TRC20, ERC20 and BEP20 are different networks.
- Copy the address from the order, never from a chat or an old order.
- Add the memo exactly as the order shows it.
- Start small. A small first swap lets you check an exchanger end to end.
Why the network matters is covered in USDT on TRC20, ERC20 and BEP20, and the route to hryvnias in how to cash out crypto to a Ukrainian bank card.
Address, network and memo come only from your order. Details from a chat, an email or a "manager" are a reason to stop and check an exchanger from scratch.
What does OnExchanger monitoring data tell you about an exchanger?
The "data from our monitoring" block on each exchanger page shows when it joined monitoring, how many directions have a live offer now, the last rate update and, after 7 days of history, the share of 10-minute checks with live rates over up to 30 days. These facts help you check exchangers; they are not a rating.
Rates come automatically from each exchanger's public XML rates file, and an offer is shown only if updated within the last 30 minutes. A listing follows once rates are connected and is no guarantee: the data helps you check an exchanger for steady operation, not for its AML rules or support.
Exchangers that work to a schedule show no rates outside business hours; that alone is not a red flag, so confirm their hours. A service not yet listed can join OnExchanger monitoring.
Which red flags should stop you when checking an exchanger?
Stop at an unusually generous rate, pressure to hurry or any request outside the order. One of these is reason enough not to pay.
Stop checking an exchanger and walk away if you see:
- a rate far above every other exchanger's offer;
- pressure such as "this rate expires in a minute";
- a request to pay a personal card or a "manager" in a messenger;
- a request for your seed phrase, card PIN or CVV;
- support that lives only in a messenger, with no website.
It is always cheaper to check an exchanger before paying than to chase your money afterwards.
What should you do if the payout is late?
Contact the exchanger's support through its website with the order number and TXID, and keep all correspondence.
First recall what you saw when checking an exchanger's rules: manual payouts follow working hours, and an AML review can hold an order.
FAQ: how to check a crypto exchanger
How do I check a crypto exchanger before my first swap?
Open it from a place you trust, compare the domain, read the direction rules and AML/KYC policy, and keep the first amount small.
Does a listing on OnExchanger mean an exchanger is reliable?
No. A listing means its rates are connected; you still need to check an exchanger yourself.
Why does an exchanger ask for verification after I paid?
Its AML/KYC rules allow identity or source-of-funds checks on incoming crypto, and the payment waits until they finish. Read those rules while you check an exchanger.
What if one exchanger's rate is far better than the rest?
Treat it as a red flag and check an exchanger like that with extra care: a rate that beats everyone is a common lure for fake sites.
Can OnExchanger return my money if the payout never came?
No. The monitor holds no funds and cannot cancel or return a payment, which is why you check an exchanger before paying. Contact the exchanger's support with the order number and TXID.
