Revision as of 15:11, 27 July 2019

Terracoin Electrum is a light wallet which uses powerful external servers to index the blockchain, while still securing the keys on your personal computer. Transactions are verified on the Terracoin blockchain using a technique called Secure Payment Verification (SPV), which only requires the block headers and not the full block. This means that wallet startup is almost instant, while still keeping your funds secure and mobile. It does not currently support advanced InstantSend and PrivateSend features.

Terracoin Electrum is a fork of the Electrum wallet for Bitcoin. While this documentation focuses on using Terracoin Electrum, full documentation of all Bitcoin Electrum features (mostly identical in Terracoin Electrum) is available at the official documentation site.

Android

Download and run the APK file from https://terracoin.io/electrum/ to set up Terracoin Electrum. You may need to grant permission to install from unknown sources, depending on your security settings. Click through the installation wizard and run Terracoin Electrum when complete.

Creating a New Wallet

Terracoin Electrum gathers configuration data when run for the first time. For more on the concepts behind this process, skip to the later sections of this guide discussing backups, security, and addresses. When setting up Terracoin Electrum for the first time, a wizard will guide you through the process of creating your first wallet. The first screen asks how you would like to connect to the remote server. Select Auto connect and click Next to continue. You will see a notice that no wallet currently exists. Enter a name for your wallet (or accept the default name) and click Next to create your wallet.

Selecting the server and naming your first wallet

You will be asked what kind of wallet you want to create. Choose between Standard wallet, Multi-signature wallet and Watch Terracoin addresses. If you are unsure, select Standard wallet and click Next to continue. You will then be asked how you want to store/recover the seed. If stored safely, a seed can be used to restore a lost wallet on another computer. Choose between Create a new seed, I already have a seed, Use public or private keys or Use a hardware device. If you are using Terracoin Electrum for the first time and not restoring an existing wallet, choose Create a new seed and click Next to continue.

Selecting the wallet type and keystore

Terracoin Electrum will generate your wallet and display the recovery seed. Write this seed down, ideally on paper and not in an electronic format, and store it somewhere safe. This seed is the only way you can recover your wallet if you lose access for any reason. To make sure you have properly saved your seed, Terracoin Electrum will ask you to type it in as a confirmation. Type the words in the correct order and click Next to continue.

Generating and confirming the recovery seed

A password optionally secures your wallet against unauthorized access. Adding a memorable, strong password now improves the security of your wallet by encrypting your seed from the beginning. Skipping encryption at this point by not selecting a password risks potential theft of funds later, however unlikely the threat may be. Enter and confirm a password, ensure the Encrypt wallet file checkbox is ticked and click Next to continue.

Entering and confirming a wallet encryption password

Your Terracoin Electrum wallet is now set up and ready for use.

Sending and receiving

You may own TRC stored in another software wallet, or on an exchange such as [CoinExchange https://www.coinexchange.io/market/TRC/BTC] or [Cratex https://cratex.io/index.php?pair=TRC/BTC], or simply want to send or receive funds as a wage or business transaction. Funds can be transferred between these source and the Terracoin Electrum wallet using Terracoin addresses. Your wallet contains multiple addresses, and will generate new addresses as necessary. Since the Terracoin blockchain is transparent to the public, it is considered best practice to use a new address for each transaction in order to maintain your privacy.

Sending

Click the Send tab to make a payment. Enter the destination address in the Pay to field, selecting a contact from the Contacts tab or manually or by pasting from the clipboard. Optionally enter a Description for to appear in your transaction history, followed by the Amount to be sent. The total amount of the transaction is the sum of the sent amount and transaction fee, which is calculated automatically. Terracoin Electrum issues a warning if the total transaction amount exceeds the wallet balance.

The wallet will request your password, then broadcast the transaction to the network and display a confirmation dialog with your transaction ID.

Receiving

You can view your receiving addresses by clicking the Receive tab. Double-click the Receiving address, then copy it to the clipboard by clicking the Copy to clipboard icon. If you intend to use the address repeatedly, you can also enter a description click Save to store the address in the Requests list. Clicking an address in the list will display the stored information in the top area, together with a QR code containing the same information.

Enter this address in the software sending the funds, send it to the person transferring funds to you or scan it directly from your mobile wallet. Once the transaction is complete, the balance will appear in the lower left corner of your wallet, and the indicator in the Requests table will change from Pending to Paid.

Once you have used an address, you can either continue using it or click New to generate a new address.

Monitoring transactions

The History tab lists all current and pending transactions. A transaction to an address in your wallet will appear in the list soon after it is made. Initially, this transaction will be marked as Unconfirmed, followed by a clock indicator on the left. As the Terracoin network processes the transaction, the status will update in the transaction history list. The network confirms transactions with a new block roughly every 2 minutes, and a transaction is considered confirmed (and therefore spendable) after six confirmations. These processed transactions are denoted with a green checkmark and the timestamp at which the transaction was made.

To view additional transaction details, right click a transaction on the History tab and select Details from the context menu. You can also use this menu to copy the transaction ID to the clipboard (this can be used as proof that a given transaction occurred), edit the transaction description for your records or view the transaction on an external block explorer.

Wallet security

Change password

To change the wallet’s password, select the Wallet > Password option from the main menu, or click on the lock icon in the lower right of the main window. Enter and confirm a new secure password. Should you forget your wallets’ password, all is not lost. Your wallet can be restored in its entirety using the backup procedure described here.

Backup

In Terracoin Electrum, a seed is a complete backup of all addresses and transactions. Access your wallet’s seed through the seed icon in the lower right of the main screen, or the Wallet > Seed main menu option. When prompted, enter the secure password you chose when setting up the Terracoin Electrum wallet.

Displaying the wallet recovery seed in Terracoin Electrum

Hand-copy the twelve words found in the box to a piece of paper and store it in a safe location. Remember, anyone who finds your seed can spend all of the funds in your wallet.

Viewing the recovery seed

Alternatively, a backup file can be saved using the File > Save Copy main menu option. This file stores the wallet’s encrypted seed along with any imported addresses. Restoring this backup will require the wallet password.

Restore

The only thing needed to recover a Terracoin Electrum wallet on another computer is its seed. You can test wallet recovery with your current installation of Terracoin Electrum by selecting the File > New/Restore menu item. A dialog will appear asking you to name your new wallet. Enter a name, select Standard wallet as the wallet type and then choose I already have a seed.

Restoring a wallet from an existing seed

Next, copy the twelve word seed into the text field.

Entering the recovery seed

If your seed was entered correctly, Terracoin Electrum gives you the option to add a password for your wallet. After restoring your wallet, Terracoin Electrum will list any existing transactions from this wallet. This process may take a few minutes, and the transactions may appear as Not Verified. This problem disappears after restarting the program.

Unverified transactions after recovery

To restore a wallet file without using the recovery seed, copy the file to the application data folder according to your operating system:

• Linux: Open Files, select Go > Go to folder, copy the path

  ~/.electrum-trc

  and paste it into the dialog box.
• macOS: Open Finder, select Go > Go to Folder, copy the path

  ~/.electrum-trc

  and paste it into the dialog box.
• Windows: Open Explorer, copy the path

  %APPDATA%\Electrum-TRC

  and paste it in to the address bar.
