# Gas

Paymaster plays a critical role in ensuring a seamless user experience when using your Smart Account. It handles all on-chain transaction processing, eliminating the need for users to manage or worry about gas tokens like ETH, offering the flexibility to pay these fees in alternative tokens. As a user, you no longer need to maintain a balance of the native gas token (ETH) in your account. <br>

Paymaster handles all aspects of gas management, ensuring that transactions are executed efficiently without requiring manual intervention or pre-funding/maintenance of ETH balance for gas fees. &#x20;

During execution, the cost of the gas associated with the transaction is deducted either from tokens being bought or tokens being sold.
