Ethereum: How to create the same (2 out of 3) multisig addresses as electrum multisig wallets with createmultisig?

Creating Multisig Addresses Using Electrum’s createmultisig Command

In this article, we will explore how to create two out of three multisig addresses using the Electrum console and its createmultisig command. This is a useful tool for securing your Ethereum private keys and managing access to multiple accounts.

Background on Multisig Wallets

Multisig wallets are designed to allow multiple people or organizations to contribute to the security of an Ethereum address while only allowing one person to spend funds from that wallet. In this case, we will create two out of three multisig addresses using public keys, rather than master private keys.

Electrum’s createmultisig Command

The createmultisig command is a powerful tool for creating multisig wallets. It allows you to generate multiple multisig addresses with different key sizes and configurations.

Here are the general steps to create two of three multisig addresses using Electrum’s createmultisig command:

• Start Electrum: First, launch the Electrum console on your computer.

• Set up your Electrum wallet: If you haven’t already, set up an Electrum wallet with the private keys for each of the two public key wallets we will create.

• Generate multisig addresses: Run the following command in a new terminal window:

electrum createmultisig 2 '["1st public key wallet 1", "1st public key wallet 2"]'

This will generate three multisig addresses with different key sizes and configurations.

Sample Output

Here is a sample output of the above command:

Multisig Address Key Size
Public Key Wallet 1:
Master Private Key: 0x1234567890abcdef (512 bits)
Second Private Key: 0x8765432109876543210 (256 bits)
Third Private Key: 0x345678901234567890 (384 bits)
Public Key Wallet 1:
Master Private Key: 0x101112131415 (512 bits)
Second Private Key: 0x2223444556667789 (256 bits)
Third Private Key: 0x3334445556667789 (384 bits)
Public Key Wallet 2:
Master Private Key: 0x9012345678901234567 (512 bits)
Second Private Key: 0x1111222233445556 (256 bits)
Third Private Key: 0x2222223334445556 (384 bits)

Creating a Single Multisig Address

To create a single multisig address using these two wallets, you can use the following command:

electrum createmultisig 1 '["1. Public Key Wallet 1", "3. Public Key Wallet 2"]'

This will generate a multisig address using both public keys we created.

Conclusion

Creating multisig addresses using Electrum’s createmultisig command is a convenient and efficient way to manage multiple accounts on your Ethereum private keys. By following these steps, you can create two out of three multisig addresses with public keys instead of master private keys. This setup allows for securely sharing access to funds between multiple people or organizations while maintaining individual control over the funds.
