Is This Crypto Exchanger Safe? 7 Things to Check Before You Send
Once crypto leaves your wallet, there’s no “undo” button. Here’s how to check a swap service before you trust it with your coins.

Swapping crypto has never been easier. There are hundreds of instant exchange services online, and most of them look almost the same: a clean page, a calculator, and a "Swap" button.
That's exactly the problem. When everything looks the same, it's hard to tell a reliable service from one that will take your coins and disappear, or quietly give you a much worse rate than you expected.
Blockchain transactions can't be reversed. So the checking has to happen before you send, not after.
Here are seven things worth checking every time.
1. Do you know exactly what you'll receive?
Before you send anything, you should see a clear amount you're going to receive, not just an "estimated" rate with no detail.
Look for:
- A fixed-rate option. This locks the amount you'll receive for a set deposit window, so the market can't move against you while your transaction confirms.
- Clear fee information. Network fees and service fees should be visible, not discovered after the swap.
If a service can't tell you what you'll get before you send, that's a warning sign.
2. Are the terms and policies actually published?
A serious service publishes its rules where you can read them:
- Terms & Conditions: what happens if you send the wrong coin, send too little, or send after the deposit window closes.
- AML/KYC policy: when (if ever) they may ask for verification, and why.
- Privacy policy: what they do with your data.
Read the part about refunds and failed deposits. That's the section you'll need if something goes wrong.
3. Can you reach a real human, quickly?
Before you swap, test the support. Send a simple question through their contact form, email or chat, and see how long it takes to get a real answer.
If nobody replies to a simple question before you've sent money, don't expect a fast reply after.
4. What do other people say?
Look for independent reviews, not just testimonials on the service's own website.
- Exchanger monitoring sites like BestChange check exchangers before listing them and show user reviews, reserves and how long each service has been operating.
- Review platforms and community forums can show you real experiences, both good and bad.
A long history of real reviews is hard to fake.
5. Who is behind the service?
Check whether the service tells you anything about who runs it: a company name, a registration country, or at least official contact details.
Anonymous services aren't automatically scams, but the more transparent a service is, the more accountable it is when something goes wrong.
6. Are you on the real website?
Phishing is one of the most common ways people lose crypto. Fake copies of real exchangers are spread through ads, direct messages and search results.
- Check the domain carefully, letter by letter.
- Use the links from official social accounts, and make sure those accounts link back to the same website.
- Be suspicious of anyone who contacts you first offering a "better rate" or "support help." Real support doesn't chase you in your DMs.
7. Start with a small amount
Even after all these checks, your first swap with a new service should be small. If it goes smoothly and quickly, you can increase the amount next time.
It costs you a few minutes, and it can save you from a much bigger mistake.
How we approach this at Hup
We built Hup around a simple idea: you send one coin, you receive another. No account to open, and nothing held on your behalf.
Here's how Hup lines up with the checks above:
- You see what you'll receive before you send. Choose a fixed rate, and the amount shown before your deposit is locked for the deposit window. Prefer to follow the market? Choose a floating rate instead.
- Our Terms & Conditions, Privacy Policy and AML/KYC policy are published on the site for anyone to read.
- Our official links all point to each other. Our website links to our X, Telegram, Instagram and Facebook, and each of those links back to hup.exchange.
- We'll never message you first asking you to send funds or share your details.
And our advice is the same for Hup as for anyone else: check us, test our support, and start small.
Your Crypto. Your Move.
