payload: A Buffer, Array, or Uint8Array of bytes, either the hash160 or private key.Can be prepended to payload.Is an integer representing the version or a Buffer if version is greater than one byte.The case where it's typically greater than one byte is for working with BIP32.Returns the base58 encoded value of type string.decode(base58str, [version]) It is the inverse of the encode() function i.e.it converts the address or wallet import format into a Buffer of bytes.It throws if the address or wallet import format is not valid.Not valid means that the version doesn't match, or the checksum is incorrect.base58str: A string that is either the wallet import format or public address.version: Is an integer representing the version or Buffer.See below for more information.Returns the decoded base58 payload of type Buffer.If version was passed to input, it is chopped off on the output.isValid(base58str, version) Validates whether the address string or wallet import format string is valid.
