Notes:

• Both origination and destination contain a finalized attribute (true or false). Typical normal XCM Transfers will have 3 key events: Origin chain Unfinalized, Origin chain Finalized, Destination chain Finalized
• If the origination chain cannot send the XCM Message, then origination.isMsgSent is false
• If the destination chain cannot process the message, then destination.executionStatus is false and error details are provided in destination.error.
