Is possible if we can see holder tokens ?

[xfwil]

Hello, sorry for giving bad issue / FR

I'm thinking why some chart app they can read all my connect after connect with metamask? its possible to get holder tokens/coin address? maybe we can know and checking because someone will forget what coin they buy.

Maybe. Thanks.

Though getting all tokens a user holds is possible (as Etherscan does it), but it is not trivial. I believe it involves quering all blocks and analyzing all events emitted. As this is very intensive on queries, having this as a feature in ethers.js might not be good. It's better to have the implementation specific to the application. Does this make sense?
