What are gas fees, and why do they matter?

Learn what gas fees are, how they work, and why every crypto transaction needs them.

Gas fees are network processing fees paid to blockchain validators (or miners) to keep transactions secure and verified.


They ensure every transaction is recorded properly on the blockchain.

 

Every blockchain has gas fees. On Ethereum, they’re measured in gwei (a fraction of ETH).


These fees go directly to the blockchain network, not RockWallet, and they’re essential for maintaining speed, security, and decentralization.

 

💡 How to avoid common issues

  • Always confirm the estimated fee before proceeding with a send, especially during high network activity periods.

  • Make sure you have enough of the gas asset (e.g., ETH for ERC-20 tokens) in your wallet before sending.

  • Confirm that you are using the correct network for your asset and recipient wallet. More on supported networks here

  • Review all details before sending, as transactions on the blockchain are permanent and cannot be reversed.
