 # Sponsor UserOperations with Pimlico

+In this guide, you will learn how to sponsor the deployment of an ERC-4337 Safe account and its user operations using [Pimlico](https://pimlico.io) infrastructure and the [permissionless](https://npmjs.com/permissionless) library.
 
 This guide focuses on how user operations are built and what happens under the hood when a Safe is configured and deployed with the `Safe4337Module` enabled. For a quick start guide, feel free to check [How to create and use a Safe account with permissionless.js](https://docs.pimlico.io/permissionless/how-to/accounts/use-safe-account).

-This initialization also includes the option to execute a call by using the `to` and `data` parameters, which we will use to enable the `Safe4337Module` contract in the Safe and give an allowance to the `EntryPoint` contract in case we want to pay the gas fees in an ERC-20 token like USDC.
