CCIPMockup Contract

The CCIPMockup contract serves as a mock representation of cross-chain interaction processes, allowing users to simulate the sending and receiving of messages across chains.

Methods:

1. sendMessage(uint32 _destinationDomain, bytes calldata _messageBody):

• For simulating the process of sending a message to another chain.
• Emits a CCIPSendRequested event upon request.

2. receiveMessage(bytes32 messageId):

• To simulate the message receipt from another chain.
• Emits an ExecutionStateChanged event to signify a successful message receipt.

Dependencies

• Client.sol: Contains definitions related to client-side functionalities.
• Internal.sol: Holds internal data structures and enumerations for the functioning of the mockup contract.

Setup and Usage

1. Installation:

npm install

• Clone the repository to your local system.
• Ensure you have the necessary dependencies installed.

2. Deployment:

npx hardhat run scripts/deploy.js

• Compile the contracts using the Solidity compiler.
• Deploy the CCIPMockup contract to your desired Ethereum network.

3. Interaction:

npx hardhat run scripts/sendTransaction.js

• Use the sendMessage function to simulate cross-chain message sending.
• Use the receiveMessage function to simulate the receipt of a cross-chain message.
