For much simple access, without downloading any software, using your private key, just go to
https://waves.exchange > Login > SoftwareIf 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 ?
After logging in, you will see all your hold tokens in the Waves blockchain. You can also sort it the way you want.
But don't be blinded by some good price there, if any, as it might untradeable. I have some tokens too under Waves which has a good price but there's no market link.
Alternatively, you can check your address at
https://wavesexplorer.com and hover to the Assets tab.
