Ethereum: How to use a read-only wallet in Bitcoin Core?
Using Ethereum in Bitcoin Core
As a user of the popular Bitcoin Core (BTC) client, you may have noticed that it allows you to create watch-only wallets for secure and private transactions. In this article, we’ll explore how to use a watch-only wallet created using the bitcoin-cli command-line tool with Bitcoin Core v2
Step 1: Create a Watch-Only Wallet
To get started, you need to create a watch-only wallet using the following command:
$bitcoin-cli-regtest createwallet "test" true
This command creates a new watch-only wallet named test and sets the disable_private_keys option to true.
Step 2: Verify the Watch-Only Wallet Creation
After creating the wallet, verify that it was created successfully:
$bitcoin-cli-regtest listwallets | grep test
The output should show the newly created watch-only wallet with the name test. You can also use the -regtest option to get more detailed information about the wallet.
Step 3: Import the Watch-Only Wallet into Bitcoin Core
Once you’ve verified that your new wallet is working, it’s time to import it into Bitcoin Core. To do this, follow these steps:
- Open a terminal or command prompt.
- Start a new session in Bitcoin Core by running:
$bitcoin-cli-regtest start
This will launch the Bitcoin Core client and create a new instance of the wallet.
- From within the Bitcoin Core session, go to Settings > Wallets and select your newly created watch-only wallet:
test.
Step 4: Create a New Transaction
Now that you have imported your watch-only wallet into Bitcoin Core, you can create a new transaction using the following command:
$ bitcoin - cli - regtest send from " test " < path / to / transaction / file
Replace test' wallet to a specified recipient.
Step 5: Verify the Transaction
To verify that the transaction was successful, you can use the following command:
$ bitcoin - cli - regtest send from " test " < path / to / transaction / file > / dev / null
This will output confirmation that the transaction was processed successfully.
That's it! With these steps, you have successfully used a watch-only wallet created with Bitcoin Core v23.0 to create and verify a new transaction.
Tips and Variations
- If your wallet is not showing up in the regtest
list, try restarting Bitcoin Core or checking for any issues with your internet connection.
- To view more detailed information about your wallet, you can use the-regtest
option with additional flags, such as–listwalletsto display all wallets in the system.
- You can also import a watch-only wallet from an existing Bitcoin Core session by using the-regtest` option and specifying the path to the imported wallet file.
