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

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

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
