decodeAddr method

@override List<int> decodeAddr(String addr, { ADANetwork network = ADANetwork.mainnet, })

Blockchain address decoder for Ada Shelley addresses. This decoder is used to decode payment addresses based on the network tag and address format.

Implementation

@override
List<int> decodeAddr(String addr, {ADANetwork network = ADANetwork.mainnet}) {
  // Decode the provided Bech32 address.
  final addrDecBytes = Bech32Decoder.decode(
    AdaShelleyAddrUtils.getAddressHrp(network),
    addr,
  );

  /// Validate the byte length of the decoded address.
  AddrDecUtils.validateBytesLength(
    addrDecBytes,
    (QuickCrypto.blake2b224DigestSize * 2) + 1,
  );

  /// Encode the address prefix based on the payment header type and network tag.
  final prefixByte = AdaShelleyAddrUtils.encodePrefix(
    ADAAddressType.base,
    network.value,
    AdaShelleyAddrUtils.decodeCred(addrDecBytes[0], 4),
    stakeType: AdaShelleyAddrUtils.decodeCred(addrDecBytes[0], 5),
  );
  return AddrDecUtils.validateAndRemovePrefixBytes(addrDecBytes, prefixByte);
