Every cryptocurrency transaction you make on the blockchain must be validated and processed on the public network. This is the blockchain transaction fee, for which you will incur a charge.
This sort of fee is blockchain-specific and only applies to transactions initiated via the Zumo Infinite non-custodial wallet. It’s what everybody using the blockchain has to pay, so these fees don’t come from Zumo and Zumo makes no profit from them.
Whenever you make a transaction of this type within the Zumo app, you will always be provided with an estimated transaction fee before you execute the transaction, which you are free to approve or reject. For more information, please visit our Fees and Charges page.
