Hello guys, does anyone know of a way to programmatically get the deployed block number of a contract. I'm writing a script to fetch custom events from contract starting from the block number the contract was deployed. Scanning from block zero doesn't seems like a viable option.

In javascriot or solidity?

So if one side has 100x100 tokens and the other side is worth 10$ there are 1000 tokens

I would suggest just doing research rather than reading uniswap code

You cant tell even what a reserve is from the code

Yeah its the amount or quantity

There are checks too i believe that give an error K and if either token doesnt equal its lastValue then it reverts out too

There is a subscribe method too that lets you set a starting block number and get all the events since then ( i think)

Sorry i didnt read your question correctly, i dont know how to get the block number of a contracts origin, its gonna be its first tranaction or its first event though maybe

The problem is that I don't know the deployed block number of each custom contracts to be scanned.
