If I can ask you one more thing.
I have a LOT of tokens and I would like to find an explorer which can say me easily how much cost those tokens (like etherscan). Do you know something like that please ?
Did you try using its explorer? since you're only looking for the tokens that's inside your waves wallet/address. It should show you the tokens that are inside it. These explorers appeared when I've searched for waves explorer.
