01 One seed, every network

The getcryptocoin wallet derives addresses for every supported network from the same recovery phrase. You do not keep a separate wallet per coin — one seed gives you a Bitcoin testnet wallet plus a wallet on each chain in the GCC family (GCC and the tenant chains TC2, TC3 and TC4). Each network has its own address format with its own human-readable prefix: Bitcoin testnet uses standard bech32, GCC uses gcc1…, TC2 uses tc21…, and so on.

02 Switching networks

The wallet shows one network at a time. To move between them, open Settings → Network and pick the chain you want — BTC testnet, GCC, or one of TC2 to TC4. The balance, address and history on the main screen all switch to the selected network. Operators running their own re-branded chain can also point the wallet at a custom Electrum endpoint here; that is covered in connecting to your own node.

Because the keys come from one seed, switching networks never asks you to back anything up again — you already hold the phrase that controls all of them.

03 Receiving coins

To receive, first make sure the correct network is selected in Settings → Network, then open the Receive screen. The wallet shows your current receiving address for that network as both text and a QR code.

  1. Confirm the network — a gcc1… address only works on GCC, a tc21… address only on TC2, and so on. Sending coins to the wrong network’s address will not credit your wallet.
  2. Tap to copy the address, or show the QR for the sender to scan.
  3. Optionally set a requested amount. The wallet encodes this as a BIP-21 payment request, so a sender scanning the QR has the amount pre-filled.

04 Sending coins

Sending follows the same shape on every network. With the right network selected, open Send and:

  1. Enter the recipient. Paste an address, or tap the scanner to read their QR. If you scan a BIP-21 request, the amount is filled in for you.
  2. Enter the amount in that network’s units.
  3. Pick a fee — see the next section.
  4. Review the recipient, amount and fee on the confirmation screen.
  5. Confirm with biometric or PIN. The wallet signs locally and broadcasts through the Electrum backend. Nothing is sent until you pass this check.

The wallet will not let you send to an address whose format does not match the selected network, which catches the most common mistake — pasting a GCC address while TC2 is active — before anything is broadcast.

05 Fees and replace-by-fee

On the Bitcoin-family chains the wallet lets you choose a fee rate when you send, trading speed against cost in testnet units. It picks a sensible default for the current network; you can raise it if you want a transaction picked up sooner.

Sends signal replace-by-fee (RBF), which means a transaction stuck at a low fee can later be re-broadcast at a higher one rather than being abandoned. The in-app control to bump the fee on an already-sent transaction is rolling out — the underlying RBF signalling is already on every send, so transactions you make now are eligible once that UI lands.
