In ERC-4337, a Paymaster is a smart contract that covers gas fees for users, either by sponsoring transactions or allowing gas fees to be paid with ERC-20 tokens instead of native tokens like ETH or MATIC. This abstraction simplifies blockchain interactions, improving the user experience and reducing onboarding friction.

Use Cases for Paymasters:

• ERC-20 Gas Payments: Users can pay gas fees using ERC-20 tokens instead of the blockchain’s native currency.

• Sponsored Transactions: Organizations or dApps can cover gas fees to enhance user experience and drive adoption.

Paymasters are particularly valuable for developers creating customer-centric applications, making Web3 interactions more accessible to a broader audience.

Notus API estimates the gas fee before processing the transaction. The final cost may vary slightly due to real-time network conditions, but we are working to improve the accuracy of these estimations.
