Blockchain address encoder for Ada Shelley staking addresses. This encoder is used to create staking addresses based on the network tag and public key.

Implementation

@override
String encodeKey(List<int> pubKey, [Map<String, dynamic> kwargs = const {}]) {
  /// Determine the network tag, defaulting to mainnet if not specified.
  final netTag = kwargs["net_tag"] ?? ADANetwork.mainnet;

  /// Check if the provided network tag is a valid enum value.
  if (netTag is! ADANetwork) {
    throw const AddressConverterException(
        'Address type is not an enumerative of ADANetwork');
  }

  /// Validate and get the Ed25519 public key object from the provided bytes.
  final pubKeyObj = AddrKeyValidator.validateAndGetEd25519Key(pubKey);

  /// Compute the public key hash based on the compressed key bytes.
  final pubKeyHash =
      AdaShelleyAddrUtils.keyHash(pubKeyObj.compressed.sublist(1));
  return AdaShelleyAddrUtils.encode(
      credential:
          AdaStakeCredential(hash: pubKeyHash, type: AdaStakeCredType.key),
      netTag: netTag,
      hrp: AdaShelleyAddrConst.networkTagToRewardAddrHrp[netTag]!,
      type: ADAAddressType.reward);
