Restoring from a seed phrase.
The fastest path from "I have a GPU or ASIC" to "shares are landing" on the testnet demo. Five steps.
01 When you would restore
The getcryptocoin wallet is self-custodial: it never holds your keys for you, and there is no server-side account to recover from. Your BIP-39 recovery phrase — the 12 or 24 words you wrote down when you first created the wallet — is the wallet. If you move to a new phone, re-install the app, or wipe a device, restoring from that phrase rebuilds every address and balance on every supported network.
I designed it this way on purpose. There is no password-reset email and no support line that can let you back in. That is the trade-off of holding your own keys, and the recovery phrase is the whole of your backup.
02 Choose Restore on first launch
Install the app from the wallets page and open it. On the very first screen you are offered two paths: Create a new wallet or Restore an existing wallet. Pick Restore.
If the app is already set up with a different wallet and you want to swap, remove the existing wallet from Settings first — that clears the local keys from the device — then re-open the app to reach the first-launch screen again. Removing a wallet does not delete the underlying coins; they live on the chain and come back the moment you restore the phrase that controls them.
03 Enter your recovery phrase
Type the words in order, one per box. The wallet auto-completes against the standard BIP-39 word list as you go, so a misspelt word simply will not match — that is a feature, not a fault. A 12-word or a 24-word phrase are both accepted; the wallet detects the length.
If you saved your phrase as a seed QR, tap the scan icon and point the camera at it instead of typing. Either way the wallet checks the phrase’s built-in checksum before continuing, so a single transposed word is caught immediately rather than silently restoring an empty wallet.
04 Set a new PIN and biometric
Once the phrase validates, you set a fresh PIN for this device and, if your phone supports it, enable biometric unlock (fingerprint or face). This is a new local lock for the new install — it does not have to match whatever you used before, because the PIN protects the on-device copy of the keys, not the keys themselves.
Under the hood the restored keys are sealed with the Android Keystore and only released after a successful biometric or PIN check, so the seed is encrypted at rest the instant the restore completes.
05 Let the wallet rescan
With the keys in place, the wallet connects to its Electrum backend and rescans the chain for every address your phrase controls. A short progress indicator runs while it walks the address gap and pulls down your transaction history. When it finishes, your balances reappear on each network you have used — Bitcoin testnet and the GCC family of test chains.
A rescan can take from a few seconds to a minute depending on how many addresses you have used and how busy the backend is. If a balance looks low immediately after restoring, give the sync a moment to complete before worrying — it is reading history, not creating it.
