This package contains the code paths necessary to encode and/or decode hexadecimal strings to Base58 encoding and back again.
Adapted from the Turtlecoin project for use in Fedoragold.
import { Base58 } from 'fedoragold-base58'
const rawAddress = Base58.decode('TRTLv3JRA772aBveLkCjG5jDvoUdKwa8YDsgLxCczL1oPei42XAMLE5QLRHM2c8oo5WbwLiB5ky7mDP7WGB53Jnp2ygHEomu3qa')
const address = Base58.encode(rawAddress)
const Base58 = require('fedoragold-base58').Base58
const rawAddress = Base58.decode('TRTLv3JRA772aBveLkCjG5jDvoUdKwa8YDsgLxCczL1oPei42XAMLE5QLRHM2c8oo5WbwLiB5ky7mDP7WGB53Jnp2ygHEomu3qa')
const address = Base58.encode(rawAddress)
