# Gas Tank

**Gas Tank**\
The Loopring Gas Tank serves as your designated account for pre-paying transaction fees. Here are additional benefits associated with filling up your gas tank in advance:

**Savings of Gas Fees**:\
By pre-funding your gas tank, you effectively circumvent the need for an extra token transfer from your account to the paymaster, resulting in substantial savings of approximately 30,000 gas fees per each transaction.

**Segregated Gas Fee Storage**:\
A dedicated account for storing gas fees eliminates concerns about surpassing the available balance after deducting the gas fee, providing you with a streamlined and worry-free transaction experience.
