Go trhough the complete deployment flow and send an incentivized message.
Now we have all the Smart Contract 📜 set we can start sending incentivized cross-chain messages. Now let complete the flow
Deploy sender contract on C-Chain
Deploy receiver contract on myblockchain
Approve the sender contract to spend ERC20 funds from the message sender address
Send the message
To deploy the sender contract run:
forge create --rpc-url local-c --private-key $PK contracts/interchain-messaging/incentivize-relayer/senderWithFees.sol:SenderWithFeesOnCChain [⠊] Compiling... [⠒] Compiling 2 files with Solc 0.8.18 [⠢] Solc 0.8.18 finished in 92.98ms Compiler run successful!

To do that lets use the function "approve" on our deployed FEE contract.
cast send --rpc-url local-c --private-key $PK $ERC20_fee_address "approve(address,uint256)" $SENDER_ADDRESS 500000000000000 cast send --rpc-url local-c --private-key $PK $SENDER_ADDRESS "sendMessage(address, string, address)" $RECEIVER_ADDRESS "Hello" $ERC20_fee_address cast call --rpc-url myblockchain $RECEIVER_ADDRESS "lastMessage()(string)" Success! The message was received on the destination chain while incentivizing the Relayer.
