Description
Jumps through all the hoops to create a connection to each L2 rpc URL and monitor its unsafe, safe and finalized heads. Currently updates to these are just logged. In future PRs they will feed into a pipeline that will detect reorgs and pull all the log data. The
ChainMonitor
implementation will encapsulate this and (eventually) just output the stream of events/data required to maintain the log database and do the consolidation/verification for interop.Tests
Added unit tests. Wiring code doesn't have much automated testing but verified by running locally and confirming head updates are reported.
