What is the transaction fee?

Every cryptocurrency transaction you make must be validated and processed on the public Bitcoin, Ethereum or Bitcoin SV blockchain (depending on which cryptocurrency you're using in the app). This is the blockchain transaction fee, for which you will incur a charge. It's important to know that this is an external, blockchain-specific expense: Zumo has no control over these charges and we make no revenue from it.  You will see an estimated transaction fee before you send funds and once the transaction has been processed this will appear on the transaction confirmation.
