A Network fee is required to ensure your transaction is confirmed by the Bitcoin mining network and fluctuates based on volume on the network. Abra does not profit from it.
We currently select a high-priority fee, to ensure fast confirmation on the blockchain. You need to have enough funds to cover the network fee.
We charge a network fee for Bitcoin withdrawals from your Abra wallet to an external Bitcoin wallet and when converting currencies.
Actual fees fluctuate based on Bitcoin network volume. A network fee is calculated at the time of a transaction and it will always be shown in the confirmation step before the transaction completes. Abra does not profit from this fee.
