Recovery Tools

Get your money out with your wallet backup alone, even without the Fiber app.

On this page

Fiber is non-custodial, so your wallet backup is all you need to get your money out. These open-source tools open the backup on your own device. They work without the Fiber app, your Fiber account or Fiber's servers.

That covers your private balance too. Most of your money in Fiber sits in Fiber's private pools on Ethereum, Arbitrum, Base and BNB Smart Chain. The pools are public contracts, and anyone holding the right keys can withdraw from them with a zero-knowledge proof. Your backup holds those keys.

What you need

  • Your wallet backup. It's a .fiberseed file you export from the app. On mobile, go to Settings > Security > Export wallet seed. On the web, go to Settings > Backup & export. You set a password for the file while exporting. See Wallet Backup.
  • A browser wallet, to send your private balance. MetaMask, Rabby or a similar wallet pays the network fee. It needs a little ETH on Ethereum, Arbitrum or Base, or BNB on BNB Smart Chain.
  • The address, for funds at a public address. Copy it from the transaction on the block explorer, or from the deposit screen you used.

Funds sent on the wrong network

If you sent crypto to your Fiber address on a network Fiber doesn't support, such as USDT on opBNB, it's still at that address. Your address exists on every EVM network, so the funds arrived, but the app doesn't show that network.

To get them out, paste the address into Fiber Recovery to get its private key. Import the key into an EVM wallet such as MetaMask, add the network, and send the funds. The address needs a little of that network's gas coin first, such as BNB on opBNB.

Keep it safe

  • Anyone with your backup file and its password can take everything in your wallet. Store them separately.
  • Fiber support will never ask for your backup file, its password or a private key. Anyone who does is trying to steal from you.
  • Fiber Recovery is only ever served from https://recovery.fiber.so. Check the address bar before you choose your backup.
  • Download the tools only from this site, github.com/fiberevm/recovery and github.com/fiberevm/cli. Check a downloaded page's SHA-256 before you open it.
  • Both tools decrypt your backup on your device. Neither sends your file, password or keys anywhere.

What these tools can't do

  • They can't recover funds without your backup file and its password. Fiber can't reset the password.
  • Sending your private balance keeps it on the same network. To move it to another network, send it to your own wallet first, then bridge it there.
  • They can't reverse a transaction or recover funds sent to an address that isn't yours.
