List all token balances for 0x742d35Cc6634C0532925a3b844Bc454e4438f44e.

I found several tokens in this wallet. It holds 500 USDT, 10.5 LINK, and 2 NFTs from the 'Bored Ape Yacht Club' collection. Would you like more details on a specific token?

Check the status and gas used for transaction 0x5c504ed432cb511de36b21cdd8187727a1714170f96219109512ee1000673974.

Transaction 0x5c50... was successful. It was included in block 12,345,678 and used 21,000 gas units with a total fee of 0.000441 ETH.

Yes. By using the `list_token_balances` tool with the wallet's address hash, the agent will return a comprehensive list of all ERC-20, ERC-721, and ERC-1155 tokens associated with that account.
