encodeKey method

  1. @override
String encodeKey(
  1. List<int> pubKey, {
  2. int? ss58Format,
})
override

Encodes a public key into a Substrate address.

This method takes a public key as a List<int> and an optional map of keyword arguments, with the 'ss58_format' key specifying the desired SS58 format for the address. It validates the arguments, encodes the public key, and returns the resulting Substrate address as a String.

Parameters:

  • pubKey: The public key to be encoded as a Substrate address.
  • kwargs: Optional keyword arguments (e.g., 'ss58_format') for customization.

Returns: A String representing the Substrate address encoded from the provided public key.

Throws:

  • FormatException if the provided SS58 format is invalid or if the public key is not a valid Ed25519 key.

Implementation

@override
String encodeKey(List<int> pubKey, {int? ss58Format}) {
  ss58Format = AddrKeyValidator.getAddrArg<int>(ss58Format, "ss58Format");
  final pubKeyObj = AddrKeyValidator.validateAndGetEd25519Key(pubKey);
  return _SubstrateAddrUtils.encode(
    pubKeyObj.compressed.sublist(1),
    ss58Format,
  );
