Role of the Paymaster

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.

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. Coinrule has automated the estimation of gas costs for each transaction. During execution, the cost of the gas associated with the transaction is deducted either from tokens being bought or tokens being sold.
