Converting Harmony ONE Addresses to Ethereum Addresses in Python

Harmony and Ethereum are both blockchain platforms, but they have distinct addressing systems. Harmony addresses typically follow a unique format, such as one1y6l5rxhpj65wefqvpme90hlg6alt2ttxcnjel5, while Ethereum addresses might look like 0x26bf419ae196a8eca40c0ef257dfe8d77eb52d66. If you've ever wondered how to programmatically convert a Harmony address to its Ethereum counterpart, this guide is for you.

Understanding the Addressing Systems

Harmony Addresses

Harmony addresses are unique and are prefixed with "one". They are longer than Ethereum addresses and are easily recognizable due to this prefix.

Ethereum Addresses

Ethereum addresses, on the other hand, start with "0x" and are shorter in length compared to Harmony addresses.

Conversion Process

While the Harmony block explorer provides a manual way to convert these addresses, doing so programmatically requires a bit of coding. Here's a simple method using Python:

Python
from bip_utils.addr.one_addr import OneAddrDecoder

def convert_to_ethereum(harmony_address):
    return OneAddrDecoder().DecodeAddr(harmony_address).hex()

By using the OneAddrDecoder from the bip_utils library, you can easily decode a Harmony address and retrieve its Ethereum counterpart.

FAQs

1. Can I use other programming languages for the conversion?

Yes, while this guide uses Python, similar libraries and functions are available in other languages.

2. Is there a direct mapping between Harmony and Ethereum addresses?

No, the conversion process involves decoding the Harmony address to retrieve its Ethereum counterpart.

3. Are there any fees associated with the conversion?

The method described here is purely programmatic and doesn't involve any blockchain transactions, so there are no fees.

4. Can I use this method for bulk conversions?

Yes, you can easily integrate this function into a loop or batch process to convert multiple addresses at once.
