Usage

yarn
forge build

1. Obtain not delivered cross chain source transaction hash
2. Go to Scan API URL: mainnet: https://scan.layerzero-api.com/v1/messages/tx/YOUR_SOURCE_TX_HASH ; testnet: https://scan-testnet.layerzero-api.com/v1/messages/tx/YOUR_SOURCE_TX_HASH
3. Copy whole JSON response of that API and replace content of data/scanApiResponse.json file.
4. Run: forge script script/SimulateReceive.s.sol --rpc-url YOUR_DESTINATION_CHAIN_RPC_URL

Remember to replace YOUR_SOURCE_TX_HASH and YOUR_DESTINATION_CHAIN_RPC_URL with correct values.

If you get an error from SimulateReceive script eg. script failed: custom error 7182306f you can do:

cast 4byte 7182306f

Example result:

LZ_PayloadHashNotFound(bytes32,bytes32)
