Address Conversion

The IoTeX blockchain supports two distinct address formats: the IoTeX "native" format (addresses that start with "io1...") and the Ethereum-compatible format (starting with "0x". This page provides an overview of these formats, their purposes, and links to relevant documentation for developers and tools for conversion.

IoTeX "Native" io Address Format

The IoTeX "native" address format is characterized by addresses that start with "io1". This format was introduced to ensure a transaction was happening on the IoTeX blockchain. An example of an IoTeX native address is:

io1qyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszq

Ethereum-Compatible 0x Address Format

IoTeX also supports Ethereum-compatible addresses that start with "0x". These addresses follow the standard Ethereum format, making it easier for developers and users to interact with IoTeX using familiar tools and conventions. An example of an Ethereum-compatible address on IoTeX is:

0x1234567890abcdef1234567890abcdef12345678

Address Conversion

To facilitate seamless interaction between these two formats, IoTeX provides tools and commands to convert addresses:

• IoTeX Address Converter Tool: This online tool allows users to easily convert between IoTeX native and Ethereum-compatible addresses. ⇒ IoTeX Address Converter

• ioctl CLI Command: The ioctl command-line client includes a command to convert addresses. This is particularly useful for developers who prefer working in a terminal environment. To convert an address using ioctl, use the following command:

  ioctl account ethaddr {io_address | 0x_address}
