4.2Network fees and advanced options

Every transfer pays a network fee to the blockchain, not to Cryptolink. The app suggests a fee that should get the transfer through quickly; you can change it in the advanced settings.

Keep the suggested feeA lower fee may leave the transfer pending for a long time or make it fail; a higher one only costs more. Change the fee only if you know why.

Ethereum and other EVM networks

On the Confirm screen (see 4.3), tap the settings button at the top, next to Cancelin the top-right corner. The Advanced screen opens.

Advanced: Network Fee, Gas Limit, Base Fee, Max Fee Rate, Max Priority Fee, Transaction Nonce 1 2 3 4 5 6
1Network Fee — the estimated fee in the network coin and in your currency.
2Gas Limit — how much “gas” the transfer may use. For a simple ETH transfer it's 21000. The app calculates it; you can't change it.
3Base Fee — the current base price of gas on the network.
4Max Fee Rate — the most you agree to pay per unit of gas.
5Max Priority Fee — the tip to validators; higher means faster.
6Transaction Nonce — the transaction's sequence number. Usually you don't change it.

7Reset — go back to the suggested values. Active when you've changed something.

Change values with − / + or type them. Reset returns to the suggested fee. Done closes the screen.Changes apply right away; to return to the confirmation, tap the back arrow or the system Back button. The (i) icons explainTap a name or the i icon to read about each value.

Networks without EIP-1559 show a single Gas Price field instead of the base fee, max fee and priority fee.

If you change the nonce, the Confirm screen shows a Nonce row with the value you chose.

WarningWhat it means
RiskyThe fee is below the recommended one: the transfer may stay pending for a while or fail.
Fee Too HighThe fee is higher than needed right now. You can send, but you'll overpay.
Used NonceA transaction with this nonce has already been executed. Tap Reset.
Insufficient BalanceYou don't have enough of the network coin for the amount plus the fee. Lower the amount or top up the network coin (for example, ETH for ERC-20 tokens).

Bitcoin

For Bitcoin, the fee is shown right in the send form — the Fee row. To change it, tap the settings button in the top-right corner of the form. The Advanced screen opens:

Reset restores the recommended rate and the Shuffle order.

If the app couldn't get the fee rate, the form shows Fee Error: Fee Rate unavailable. Please, check fee rates manuallyThe connection to the server has been lost. To proceed, set up the fees manually using the data on the site. Check your internet connection and open the form again, or set the rate manually in Advanced.

For Litecoin, Bitcoin Cash, Dash and eCash the rate is set automatically; only the Inputs/Outputs option is available.

Bitcoin Advanced: Fee, Fee Rate with − / +, Inputs/Outputs, Reset and Done 1 2 3 4
1Fee — the total fee for the transfer. Until it can be calculated, the row shows N/A.
2Fee Rate — satoshis per byte of the transaction.
3Inputs/Outputs — the order of inputs and outputs.
4Reset — go back to the recommended values.
