Transaction Lock secret

SecretLockTransaction

Secret Lock Transaction is used to create a new secret lock. For creating use NewSecretLockTransaction().

Following parameters required:

• mosaic - a mosaic that will be locked
• duration - how long mosaic will be locked
• secret - generated secret
• recipient - recipient of the mosaic
