$3

You can enforce your instance of Base58Check to verify and generate a particular
_version_ of coin, or to use a different Base58 dictionary.

`js
Base58Check.create({
pubKeyHashVersion: 4c, // Dash (00 for Bitcoin)
privateKeyVersion: cc, // Dash (80 for Bitcoin)
dictionary: 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz,
});
