Question

I am using web3 sdk of Solana to query balances or make transactions. Now I would like to know if it's possible to achieve one of the following actions:

1. Get a list of the assets from a provided wallet address.
2. Get a wallet address from a provided nft address. This one will be better if both are possible.
