Access to chain id in wildcard event filters

Not quite suitable for multichain indexer. Since it doesn't hold event context. I can't parse right WETH address for it which are different per chain.

Hey @chrisais9,

Interesting. Just FYI, although it's not a nice API this is achievable if you define the event separately per chain in your config. And give the contract a different name. You can pass the same contractRegister callback to each of them with different eventConfig options.

Since the filter is not reactive to the event that gets passed to the handler, but rather, it defines the filters applied in hypersync before returning to the indexer.

Do you have any suggestions for a preferred API?

Maybe a field called "getEventFilters" which is a callback that takes (chainId) => eventFilters. Then a different set of eventFilters can be created per chain on the indexer start up?

Callback approach with chainId sounds great! Would be enough for now.
