Can I estimate gas for a specific EVM transaction before sending it?

Yes! Use the `estimate_evm_gas` tool by providing the chain, sender, recipient, and amount. It will return the estimated gas limit and price for that specific interaction.

How do I monitor a wallet for new incoming transactions automatically?

You can use the `create_subscription` tool to set up a webhook. This allows you to receive real-time notifications whenever a transaction occurs on the specified address and chain.

Can I check balances for multiple token types at once?

Yes, the `get_wallet_portfolio` tool allows you to specify token types like 'native', 'fungible' (ERC-20), and 'nft' to get a comprehensive view of an address's holdings.
