[Feature Suggestion] Easier, more performant event querying by making contract deployment data available

[escottalexander]

It would be nice if useScaffoldContract returned a deployedOnBlock property that was the block the contract was deployed on.

I seem to always be hardcoding the fromBlock in useScaffoldEvents. Is there a fancy way to get this programmatically without reading my contract deployment files? Might would be nice if useScaffoldEvents fromBlock was the contract deploy block by default.

Feel free to close this if it is not possible for some reason or if there is a simple work-around I have not discovered yet.

Adding to this: maybe it'd be possible to add the deployedOnBlock prop in the deployedContracts.ts file?

Sounds very useful for Ponder indexing too. We can get this information from the transaction receipt from the deployment and add deployedOnBlock prop to deployedContracts.ts file. I can work on this!

Sure! That was fast. I will check it out tomorrow.

@escottalexander And now you can automatically use this on the events hook #1134

Thanks, @damianmarti! I am excited to see that you have created a PR for the Foundry version as well. Looking forward to updating the Arbitrum Extension (@Pabl0cks) when all these changes are merged and available in create-eth.
