Loading Regtest Wallet in Bitcoin Core: A Step-by-Step Guide

Bitcoin Core, the popular open-source Bitcoin software, offers a variety of ways to manage and interact with your Bitcoin wallet. One such method is regtest, which allows you to test the functionality of your wallet without storing Bitcoins on your computer. In this article, we will walk you through the process of loading a regtest wallet in Bitcoin Core 27.0.0.

Problem: Unknown wallet name

When trying to load a regtest wallet using bitcoin-cli -regtest loadwallet , an error may occur if the wallet name is unknown. This issue occurs because regtest requires the full path and name of the wallet file, which may not be known to some users.

Solution: Use the “listwallets” command

To resolve this issue, we will use the combination of the “listwallets” command and the “-regtest” flag with “loadwallet”. This approach will allow you to list all the wallets associated with your Bitcoin Core installation and then select the one you want to load.

How ​​it works:

• Run listwallets:

• Open a terminal or command prompt.

• Go to your Bitcoin Core installation directory (e.g. /path/to/bitcoincore).

• Run the following command:

bitcoin-cli - regtest listwallets

• Specify your wallet:

• The output of listwallets should show a list of wallets, including their names and file paths.

• Search for the wallet you want to load. If you are not sure, search for a name that matches your wallet file path, or use the -regtest flag to refine your search.

Loading Regtest Wallet:

Once you have identified the correct wallet, run the following command:

bitcoin-cli -regtest loadwallet 

`

Replace “” with the actual name of the wallet. For example:

bitcoin-cli -regtest loadwallet bitcoin-01

This will load the regtest wallet you specified.

Tips and Variations:

• If you are using a specific version of Bitcoin Core, make sure it is compatible with your wallet file format.

• You can also use the “–datadir” flag to specify the directory where Bitcoin Core stores its data. For example:

bitcoin-cli -regtest loadwallet -datadir /path/to/bitcoincore/bitcoin-01

This will allow you to load the regtest wallet without specifying the exact path to the file.

Conclusion:

Loading the regtest wallet in Bitcoin Core 27.0.0 can be done using the “listwallets” command and the “-regtest” flag with “loadwallet”. By following these steps, you should be able to successfully load the specified regtest wallet, even if its name is unknown.
