Interact with a decentralised application: store a value on the blockchain.
We have set up a really simple stateful smart contract to test the application calls. This smart contract is expecting an integer as a parameter. It then stores the sum of values and the number of values as global states within the application and the last value sent as a local state in the user account.
Overview of the Smart Contract's behavior
Once you've put some money into your account, you can run the Unix example program with the

If the account calling the smart contract never opted in the application, it will be automatically done.
