Interestingly you can use the author's prompt and ask it to behave like a Ethereum RPC node. You can then instruct it to retrieve your balance or any erc20 balance, broadcast transactions, burn and mint tokens.. everything looks perfect and the block number even increase between attempts. The only part where it gets weird is when you ask to retrieve the price of WETH/USDC on uniswap. The commands and contract addresses are correct but the price returned is far from correct
