Ethereum Library: Generating HD Keys/Addresses in Python

As an Ethereum developer, you require a reliable way to generate high-quality HD keys and addresses for your projects. This article provides a Python library that meets your requirements.

Overview

The following library uses the secp256k1 module from the Bitcoin foundation to derive HD keys and addresses from private keys. It’s designed to be fast, secure, and easy to use.

Installation

To install the library, run the following command:

pip install secp256k1-py

Usage

Create a new Python file (e.g., ethereum_utils.py) and import the library:

import secp256k1


def derive_hd_key(private_key):

    """

    Derive an HD key from a private key.


    Args:

        private_key (bytes): The private key to derive from.


    Returns:

        bytes: The derived HD key.

    """

    return secp256k1.derive_private_key(private_key)


def generate_address(hd_key, network):

    """

    Generate an address from an HD key and network.


    Args:

        hd_key (bytes): The HD key to use.

        network (str): The Ethereum network to use (e.g., "mainnet", "testnet").


    Returns:

        str: The generated address.

    """

    return secp256k1.hodl(hd_key, network)

Example Usage

Here’s an example of how you can use the library:

import ethereum_utils







Generate a private key from a seed phrase

seed_phrase = "your_seed_phrase_here"

private_key = ethereum_utils.derive_hd_key.from_secret(seed_phrase)



Derive an HD key

hd_key = ethereum_utils.derive_hd_key(private_key)



Generate an address on mainnet

address = ethereum_utils.generate_address(hd_key, "mainnet")


print(address)

Network-Specific Settings

The library uses the secp256k1 module to derive HD keys and addresses. However, it also provides some network-specific settings that you can use depending on your needs.

• To generate testnet addresses, set network="testnet" in the generate_address() function.

• To generate mainnet addresses, set network="mainnet" in the generate_address() function.

• You can also specify a specific network version (e.g., “mainnet-v1.0”) by passing it as an argument to the derive_hd_key() and generate_address() functions.

Commit Message Guidelines

For your commit message, follow these guidelines:

• Use the present tense (e.g., “Add library for generating HD keys/addresses”)

• Keep the message concise and descriptive

• Avoid using abbreviations and acronyms unless they are widely recognized in the community

Here’s an example of a well-formatted commit message:

git commit -m "Add library for generating HD keys/addresses"

By following these guidelines, you can create a reliable and maintainable Python library that helps you generate high-quality HD keys and addresses for your Ethereum projects.
