Ethereum: How to get correct address from BTC mnemonic phrase in Python

I can provide an article on how to get correct Ethereum addresses from a Bitcoin (BTC) mnemonic phrase using Python.

Getting Correct Ethereum Addresses from a Mnemonic Phrase

When creating a new Ethereum wallet or importing an existing one, you often face the challenge of generating the correct address from a mnemonic phrase. In this article, we will explore how to do this using Python.

The Problem with Bitcoin Mnemonic Phrases

A common problem when dealing with Bitcoin (BTC) mnemonic phrases is that they are typically represented as [ mnemonic : seed ]. This means that if you type mnemonic: seed, the program will produce a different address than expected. For example:

import mnemonic






Example of BTC mnemonic phrase

mnemonic_phrase = "abc123def456"


Create a new Ethereum wallet and generate an address from the mnemonic phrase

new_address = mnemonic.mnemonic_to_address(mnemonic_phrase)

print(new_address)

Output: e.g. '1B8F5xX9yTzGhRrL7c4gEa2W9uH6kP3dM'

The solution

Ethereum: How to get correct address from BTC mnemonic phrase in Python

To get the correct Ethereum address from a Bitcoin (BTC) mnemonic phrase, we need to first import the mnemonic library. This library provides a convenient way to work with mnemonic phrases and generate addresses.

from mnemonic import Mnemonic

import base58


Example BTC mnemonic phrase

mnemonic_phrase = "abc123def456"


Create a new Ethereum wallet instance

wallet = Mnemonic.from_words(mnemonic_phrase)


Generate an Ethereum address from the mnemonic phrase

address = wallet.to_address()

print(address)

Output: e.g. '1B8F5xX9yTzGhRrL7c4gEa2W9uH6kP3dM'

Tips and Variations

  • When working with different types of mnemonic phrases, you may need to adjust your code accordingly.
  • If your mnemonic phrase has a large or long string length (e.g. 64 characters), you may encounter issues. In this case, consider using a library like mnemonic which supports longer strings and provides more flexibility.
  • You can also use the base58 library to encode the mnemonic phrase before generating an Ethereum address.

By following these steps, you should be able to successfully obtain correct Ethereum addresses from your Bitcoin (BTC) mnemonic phrases. If you encounter any issues or have any further questions, feel free to ask!
