 MissionEnrolment2024 provides a streamlined single-page application flow for mission enrolment, verification, and NFT migration:  
 
-1. Connect your Ethereum wallet to the application using the "Connect Wallet" button.  
-2. Navigate through the mission enrolment stages:  
-   a. Enter your ENS (Ethereum Name Service) name or Ethereum address for identity verification.  
-   b. The application will automatically retrieve and verify your ETHGlobal POAPs to confirm event attendance.  
-   c. Review the details of your mission participation, including verified events and achievements.  
-3. Transfer your POAP using Chainlink CCIP:  
-   a. Initiate the transfer of your ETHGlobal POAP from Gnosis chain to either Base or Optimism.  
-   b. Confirm the transfer transaction using your connected wallet.  
-   c. Wait for the cross-chain transfer to complete, ensuring data integrity and security.  
-4. Create an onchain attestation for your mission enrolment:  
-   a. Click the "Create Attestation" button to initiate the process.  
-   b. Sign the attestation transaction using your connected wallet.  
-   c. Wait for the transaction to be confirmed on the Ethereum network.  
-5. Once confirmed, view your attestation details, which are now immutably recorded on the blockchain.  
-6. Explore the "Recent Attestations" section to see other verified mission enrolments and the growing community of participants.  
-
-This streamlined process ensures a transparent and verifiable record of your mission enrolment, leveraging the security and immutability of blockchain technology. The Chainlink CCIP integration allows for secure cross-chain POAP transfers, enhancing the interoperability of the application. The single-page application design provides a seamless user experience throughout the entire enrolment, verification, and cross-chain transfer process.
