Ethereum: How to get public key from mnemonic (StarkNet)

I can provide you with a detailed guide on how to extract a public key from a mnemonic (StarkNet) on Ethereum.

What is a mnemonic?

A mnemonic is a string of words that helps you remember your private keys and other sensitive information. In the context of Starkware, a blockchain platform developed by Vitalik Buterin, mnemonic tools like StarkNet allow users to generate private keys and extract public keys from them using their mnemonics.

Why extract a public key from a mnemonic?

Extracting a public key from a mnemonic offers several advantages:

Easy recovery in case of data loss: If you lose access to your Starkware wallet or mnemonic, you can still recover your private key and make transactions.

Reduced risk of account compromise: By using a mnemonic to extract a public key, you reduce the risk of an attacker compromising your accounts or private keys.

How to get a public key from a mnemonic (StarkNet)

To get a public key from a mnemonic in Starkware, you will need:

A valid Starkware wallet that supports mnemotools.

The corresponding Starkware mnemonic.

Here is the step-by-step process with StarkNet:

Step 1: Install StarkNet

First install StarkNet on your local machine by following these steps:

Clone the StarkNet repository from GitHub: git clone

Change to the StarkNet directory:cd StarkNet

Build and install StarkNet withnpmoryarn:npx cross-starknet build


Step 2: Load the mnemonic

Upload your mnemonic file (.mn.mnemonic) to the Starkware CLI:


stark-cli mnemonic load .mn.mnemonic

Replace with the actual name of your mnemonic file.

Step 3: Derive the Public Key

Use the derive command to derive a public key from the loaded mnemonic:

stark-cli derive --mnemonic --publickey


This will generate the derived private and public keys in JSON format. You can then use these keys to sign transactions or interact with your Starkware wallet.
Important Notes

Make sure you have a valid Starkware wallet installed on your device.

Thederivecommand assumes you have an empty mnemonic file. If you have a mnemonic file with existing data, you will need to use the-f option to specify the file format (e.g..mn.mnemonic`).

Deriving a public key from a mnemonic is not the same as using a mnemonic to sign transactions. The private and public keys obtained through StarkNet are different from those generated with the built-in Starkware tools.
