base-builds

imagine you want to take a snapshot of all the holders of token X and their balance. how would you do it?

basescan is the easy way.
the hard way would be using the contract to get all the addresses the token has been sent to and then get the balance for each user to ensure they are still holding.

probably read all the transfers from when the token has been minted, otherwise https://docs.bitquery.io/docs/examples/token-holders/token-holder-api/, but not sure about the reliability

oh wow. I thought there was an easier thing than doing this. wild

Building ponder.sh. EVM, TypeScript, open-source enjoyer.

Depends on storage layout. If all the contract gives you is a   

mapping(address account => uint256) private _balances;

Unfortunately you cannot iterate over that as the evm storage doesn’t hold the array of Object.keys in memory/storage 

You could however use an event filter or other means to get a list of all potential holders and iterate over that with a custom view function

@fucory could you use a custom view function for this?

I used basescan and exported csv style to excel for $OIL, yet there has to be more tech savvy ways - using one of the data platforms
