Crypto wallet security: 12 tips that stop most scams

Most people who lose crypto aren't victims of sophisticated hacks; they're victims of deception. A fake link, a friendly "support agent" on Telegram, or an address that wasn't checked. These 12 simple tips prevent most of it.

1. Always check the site address

Phishing pages copy the real site exactly; only the address is slightly off, an extra letter or a different domain. TetWallet's only official address is tetwallet.com. Bookmark it or install the app to your home screen, and always open it from there, never from links sent to you.

2. Set an anti-phishing code

In TetWallet you can set a personal anti-phishing code that appears in every official email. An email in TetWallet's name without your code is fake.

3. Turn on two-factor authentication

A password alone isn't enough. With 2FA, even a leaked password can't be used to withdraw. Google Authenticator is safer than SMS.

4. Never share codes or passwords

No real support agent, group admin or "expert" will ask for your password, 2FA code or recovery phrase. Anyone who does is a scammer, without exception.

5. Beware of fake support on Telegram

Scammers create accounts with the names and pictures of popular wallets and message people who asked questions in groups. TetWallet's only official Telegram accounts are the bot @tetwalletbot and the channel @tetwalletofficial. Support happens only on the site and in the bot, and we never message you first.

6. Use a unique, strong password

Your wallet password must not be used anywhere else. When any site leaks, scammers try the same email and password on wallets. A password manager makes this easy.

7. Secure your email like your wallet

A custodial wallet is recovered through email, so your email is the master key. Give it a strong password and 2FA as well.

8. Check the destination address three times

Clipboard malware swaps an address you copied for the scammer's. After pasting, compare the start, middle and end with the original. Never copy an address from your transaction history; see address poisoning in How to spot fake USDT.

9. Use the address book

Save addresses you send to often, carefully, once. In TetWallet a new address becomes usable after 24 hours, so if someone gets into your account, they can't add their own address and withdraw immediately.

10. Pick the right network

USDT exists on several networks and sending on the wrong one can put funds out of reach. Always ask the receiver. Guide: Which network should you send USDT on?

11. Install only from official sources

Fake wallet apps, especially APK files passed around in channels, are common. Install TetWallet only from the official download page on tetwallet.com.

12. Don't believe offers that are too good

Guaranteed daily returns, "flash USDT", coin doubling, USDT below market price, or an airdrop that needs you to connect your wallet to an unknown site: all signs of a scam. Golden rule: if it sounds unbelievable, don't believe it.

If you think your account is at risk

1. Change your password immediately.
2. Check or reset your two-factor authentication.
3. In your profile, review Active devices and sign out any you don't recognise.
4. Contact official support from the site or the bot.
