Addresses

Irys uses two address formats, one base58 encoded (i.e 2QZrWyPPi4XukwiJQrVmUvuPQ57F) known as the Irys address, and one hex encoded (i.e 0x64f1a2829e0e698c18e7792d6e74f67d89aa0a32), the Execution address - which is a traditional EVM address.
Both address types are cross-convertable, with the execution address being a hex encoding of the decoded Irys address bytes.
@irys/js has some conversion utilities you can use:

import {irysToExecAddr, execToIrysAddr } from "@irys/js/common/utils"
 
const irysAddress = "2QZrWyPPi4XukwiJQrVmUvuPQ57F";
const execAddress = "0x64f1a2829e0e698c18e7792d6e74f67d89aa0a32"
irysToExecAddr(irysAddress) //  "0x64f1a2829e0e698c18e7792d6e74f67d89aa0a32"
execToIrysAddr(execAddress) //  "2QZrWyPPi4XukwiJQrVmUvuPQ57F"

Irys & execution addresses are derived using the same private key, so your Irys execution address will be identical to your usual EVM one.
