[User] List all ERC20 tokens where the price is between $1 and $10, including their names, symbols, and contract addresses.

[User] I think there's an error in your query - the token_prices_latest table isn't in the schema. Can you modify it to use the token_balances table instead?

[User] That doesn't seem right either. Let's just get the basic ERC20 token information without price filtering for now.
