Calling Your Contract

Smart contract messages

To communicate with Smart contracts, we use Messages: Calling Contract

It's possible to pass two kinds of messages: - messages change a Smart contract's state is sent as transactions - messages that do not change the state is called by RPC calls.

Let's try to read our Smart contract value by get() message call.

Calling Contract get() value

Second, let's change a Smart contract state by sending a "message", send flip() message that flips Smart contract to boolean flag.

Flip call is a transaction.

Verify the result: Call last Flip value.

Using these two kinds of messages, your DApp can be easily read and written the Smart contract data.
