publicKeyForAddress method

@override String publicKeyForAddress(String address)

Public key from the credential's walletAdditionalAddresses, used to construct a PSBT.

Implementation

@override
String publicKeyForAddress(String address) {
  String instrumentationOperation() {
    final user = _state.user;
    if (user == null) {
      throw DynamicStateException("not authenticated — sign in first");
    }
    final matches = user.verifiedCredentials.map((credential) => (credential.walletAdditionalAddresses == null ? null : firstWhereOrNull<WalletAdditionalAddress>(credential.walletAdditionalAddresses!, (item) => item.address == address))?.publicKey).where((v) => v != null).map((v) => v!).toList();
    final publicKey = firstOrNull(matches);
    if (publicKey == null) {
      throw DynamicStateException("no public key on record for that Bitcoin address — walletAdditionalAddresses is missing or empty on this credential");
    }
    return publicKey;
  }
  return _api.instrumentation.run("btc.publicKeyForAddress", instrumentationOperation);
