Can I check the balance and metadata of a specific Moonriver address?

Yes! Use the `get_account_info` tool by providing the wallet address. Your agent will return the current balance and associated account metadata.

How can I track token transfers for a specific user?

Use the `list_transfers` tool with the user's address. It will retrieve the history of token transfers (ERC-20/ERC-721) for that specific account.

Is it possible to look up a transaction using its hash?

Absolutely. Use the `get_extrinsic` tool and provide the transaction hash to get full details about that specific operation on the network.
