When you send a native asset from your Fireblocks Console, you can choose between net and gross fees on the New Transfer window.

Net fees

Net fees are deducted from the originating vault account's balance and not from the transfer amount. Your counterparty receives the exact displayed transfer amount. For some blockchains, Fireblocks can only estimate the fee, not predict the exact final network fee. 

Gross fees

Gross fees are supported when the source of the transaction is your vault account but not when you submit transactions from a connected exchange account. These fees are deducted from the displayed transfer amount. Your counterparty receives the displayed transfer amount minus the final fee. The benefit here is that your source account balance is expected to be deducted approximately the displayed amount (subject to blockchain fluctuations). This is especially useful when you want to empty the source account. As with net fees, Fireblocks can only estimate the fee for some blockchains and cannot predict the exact final network fee.

Selecting net or gross fees

1. Create a new transfer for a native asset such as BTC, DASH, etc.
2. Under the transaction amount, select Net or Gross.
3. Set a tentative or custom fee. 
4. Select Submit for Approval to initiate the transfer.
