CCTP Transaction test (transfer 1 usdc)

0. Pre-requirement: enough testnet USDC from Circle USDC faucet. This is required by the LitePSM mock contract which expects USDC to be present on the deployer wallet (for the swapUSDSToUSDC call to work).
1. Call Controller.mintUsds
   • usdsAmount: 1000000000000000000
   • tx
2. Call Controller.swapUSDSToUSDC
   • usdcAmount: 1000000 (usdc uses 6 decimals)
   • tx
3. Call Controller.transferUSDCToCCTP
   • usdcAmount: 1000000
   • destinationDomain: 5 (solana devnet)
   • tx
4. Get offchain attestation message from Iris (docs)
   • Query https://iris-api-sandbox.circle.com/messages/0/{transferUSDCToCCTP_transaction_hash_from_above}
   • Note down returned messages[0].message and messages[0].attestation to be used in the next step
   • example response using tx above
5. Receive USDC on solana devnet
   • Copy repo: https://github.com/circlefin/solana-cctp-contracts/tree/master/examples (link can be found here)
   • Follow the readme instruction for v1 Receive Message
     • cd examples
     • cp .env.example .env
     • Update .env

       MESSAGE_HEX= messages[0].message
       ATTESTATION_HEX= messages[0].attestation
       REMOTE_TOKEN_HEX=0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238 # USDC on Sepolia
       REMOTE_EVM_DOMAIN=0 # CCTP domain id for Sepolia
