Getting Started

Create your account, secure it, and make your first deposit.

Setup takes a few minutes, and there's no seed phrase to write down.

1. Get Fiber

On Android, download Fiber from Google Play. On iPhone and computers, use the web app at app.fiber.so. The iOS app isn't in the App Store yet.

2. Create your account

Choose Continue with email, then enter the 6-digit code Fiber sends you. If you don't have an account yet, that creates one. You can also create a Fibertag account with a username and password. Passwords can't be reset, so add a verified email or phone to that account too.

Your account starts with a Fibertag, your public @handle for getting paid by other Fiber users. To change it, tap your name at the top of Home and choose Account details. If SMS codes don't reach your number, use email. See Your Account.

3. Secure your account

  • Verify your phone number in Account details (web: Settings > Account). The $25 deposit bonus and US bank details require it.
  • Turn on App lock in Settings > Security > Account security.
  • Add a passkey or authenticator on the same screen, for an extra check on sends, trades, and account changes.
  • Export an encrypted wallet backup from Settings > Security > Export wallet seed, and keep the file and its password apart. See Wallet Backup.

Never share verification codes, passwords, your backup file, or its password. Fiber will never ask for them.

4. Make your first deposit

  1. On Home, tap Receive.
  2. Choose USDC or USDT, then the network you're sending from.
  3. Copy the address or scan the QR code, and send from your wallet or exchange.

The coin and the network must both match what you picked. opBNB is not BNB Smart Chain. Deposits on unsupported networks don't appear in Fiber, so check Supported Assets & Networks, and consider a small test first.

Fiber moves your deposit into your private balance automatically. Base is instant. Most networks take from seconds to about 35 minutes. See Deposits.

Another Fiber user can pay your Fibertag for free. Eligible users can also get US bank details.

5. Start using Fiber

Interest on your USD balance is on by default (Interest). From here you can send money, trade, and work toward the $25 deposit bonus. For anything else, ask the assistant, or ask it for a person.
