encodeKey method

@override String encodeKey(List<int> pubKey, { String? hrp, })

Overrides the base class method to encode a public key as a P2WPKH address.

Implementation

@override
String encodeKey(List<int> pubKey, {String? hrp}) {
  hrp = AddrKeyValidator.getAddrArg<String>(hrp, "hrp");

  /// Validate and process the public key as a Secp256k1 key.
  final pubKeyObj = AddrKeyValidator.validateAndGetSecp256k1Key(pubKey);

  /// Set the witness version and obtain the public key bytes.
  const witnessVer = P2WPKHAddrConst.witnessVer;
  final pubKeyBytes = pubKeyObj.compressed;

  /// Encode the processed public key as a P2WPKH address using Bech32.
  return SegwitBech32Encoder.encode(
    hrp,
    witnessVer,
    QuickCrypto.hash160(pubKeyBytes),
  );
