Secure your wallet

In a self-custody wallet, only you can protect your crypto: FxWallet can't recover a lost mnemonic phrase or reverse a transaction. These habits cover the ways people most often lose crypto.

1. Back up your mnemonic phrase offline​

Your mnemonic phrase is the master key to your wallet. If you lose it, you lose the wallet, and anyone who sees it can take everything in it.

  • Write it on paper, or keep it on a metal backup plate, and store it somewhere safe from fire and water.
  • Check that the words are in the right order and easy to read.
  • Never keep it as a screenshot, a photo or a note, and never send it in a message.

See Back up your mnemonic phrase.

2. Lock FxWallet​

Turn on Biometrics in Me → Security, so a lost or stolen phone can't open FxWallet. Use a 6-digit passcode that's hard to guess: not 123456, and not your birthday.

3. Never share your mnemonic phrase or private key​

FxWallet will never ask for them, and no real support agent ever will. Anyone who asks for either one is trying to steal your crypto. See Fake support and QR code scams.

4. Install FxWallet only from official sources​

Download it from the official website or the official app stores, and check the developer's name before you install it. Fake apps copy FxWallet's name and icon. See Download FxWallet and check it's genuine.

5. Check what you connect and approve​

  • Connect only to DApps you trust, and check the website's address before you connect.
  • Read what you approve. An unlimited token approval lets a contract spend all of that token in your wallet.
  • Revoke approvals you no longer need: on the Wallet tab, tap More → Approvals.

See Token approvals.

6. Keep FxWallet up to date​

Updates include security fixes, so install them when FxWallet asks. See Keep the app up to date.
