Send a Roundtrip Message

Send roundtrip message

Alright, now let's send the message:

cast send --rpc-url local-c --private-key $PK $SENDER_ADDRESS "sendMessage(address)" $RECEIVER_ADDRESS

To check whether the message has been received, we can call the roundtripMessage() function on the sender contract.

cast call --rpc-url local-c $SENDER_ADDRESS "roundtripMessage()(string)"

If successful, you should see the following output:

"Hello World!"

To understand in more detail what happened, check out the relayer logs:
