What is the current AVAX balance of 0x742d35Cc6634C0532925a3b844Bc454e4438f44e?

I've checked the address on the Avalanche C-Chain. The current balance is 15.42 AVAX.

Show me the last 5 ERC-20 transfers for wallet 0x123...

Fetching recent token activity... I found 5 recent transfers, including 100 USDC received and two outgoing transfers of JOE tokens. Would you like the transaction hashes for these?

Get the ABI for the contract at 0x60ae616a2155ee3d9a68541ba4544862310933d4.

I have retrieved the ABI for the verified contract. It contains 24 functions, including `swapExactTokensForTokens` and `addLiquidity`. I can help you format a specific call if needed.

Yes. Use the `get_avax_balance_multi` tool and provide a comma-separated list of up to 20 addresses to get all balances in a single response.
