How are gas fees set or calculated in RockWallet?

Gas fees are small network fees paid to blockchain miners/validators to process your crypto transactions securely. These fees are not set by RockWallet, they are determined by the blockchain network based on real-time demand.

RockWallet estimates gas fees for you based on the network. However, understanding how they’re determined can help you make sense of the costs:

Gas Fee Formula

Gas Fee = Gas Price × Gas Limit

• Gas Price:
  This is the amount you’re willing to pay per unit of gas, measured in GWEI (a small unit of ETH).

  
  1 GWEI = 0.000000001 ETH.

  
  Think of it like paying per gallon of gas for your car - higher gas prices can make transactions process faster.

• Gas Limit:
  This is the maximum amount of gas allocated to complete a transaction.
  For simple ETH transfers, the gas limit is usually 21,000 units.
  More complex transactions (like swaps) require higher limits.

Example:

If the gas price is 1 GWEI and the gas limit is 21,000, your total gas fee would be:
1 GWEI × 21,000 = 21,000 GWEI = 0.000021 ETH.

💡 Tip: You don’t need to calculate this manually, RockWallet automatically displays an estimated network fee before you confirm your transaction.

Because gas fees fluctuate with network congestion, the final cost may change slightly between when you start and confirm your transaction.

Important Reminder: Gas Fees Are Separate From Payment Fees. 

Gas (network) fees are charged by the blockchain network, not by RockWallet. They are separate from any card processing fees, ACH bank transfer fees, or other payment provider fees that may apply when transacting with digital assets through RockWallet.

Your total transaction cost may include both RockWallet service fees (set by our payment partners) and blockchain gas fees (set by the network).

This distinction helps keep your transactions transparent and ensures you know exactly what you’re paying for.
