signTransaction method

@override Future<Uint8List> signTransaction(Uint8List tx)

Signs a raw transaction.

Implementation

@override
Future<Uint8List> signTransaction(Uint8List tx) async {
  // Standard interface implementation. For EVM, we prefer TransactionRequest.
  // This can be implemented to sign raw bytes if the signer supports it.
  return signer.signHash(tx);
}
