# Get maximum transferable value

> This operation retrieves the maximum amount that you can transfer from a wallet or a specified wallet address, along with the corresponding transaction fee.

You must specify `to_address` in your query because it affects the transaction fee.

<Note>This operation is applicable to Custodial Wallets and MPC Wallets only.</Note>
