I want to know how much a wallet has bought and sold the assets. I need to know it in dollars. For example, 500$ of assets bought and sold by a wallet

Something like this is possible in web3?

You basically have 2 options.

The first is to set up a node and crawl the whole blockchain for token transfers.

The second is to use a third-party service such as Alchemy, which has already crawled the blockchain and returns the list of all the holdings. Read more about it here.


You can also track the dex where they brought and sold the tokens for events involving that specific address.
