[yourbuddyconner]

Input:

• Transaction hash corresponding to Send call on BridgeRouter.

How this will work:

• Origin Chain: Get Transaction via transactionHash
• Origin Chain: Get Send event, extract _destination and _recipient
• Origin Chain: Get Dispatch event, extract _leafIndex, _committedRoot, _messageHash
• Origin Chain: Get Update event, extract _committedRoot
• Destination Chain: Get Update event, extract _committedRoot
• Destination Chain: Get Process event, extract _messageHash
• Destination Chain: Get Transfer event, extract address

you can use the bridge message to do this for most cases

First crack at this, not great, lots of this should end up in the multi-provider library as convenience functions: https://gist.github.com/yourbuddyconner/8e64948061247d21975b5c50292e4c9e
