Kotlin sample
Prove that arbitrary transaction intent cannot reach a Kotlin service signer through the Torq client.
Developer Preview. Use the Kotlin client supplied with your approved application. Keep service credentials and signing material in their approved server boundaries.
This executable negative sample confirms that a raw caller-created transaction fails closed before the signer is invoked.
