# Sponsor job

The ees-sdk makes it easy to generate an EIP-712 signature required to sponsor a job. As mentioned [here](https://docs.ees.xyz/concepts/sponsored-jobs), sponsoring a subscription means that all execution fees associated with execution of the job are paid by you.

```typescript
const signature: `0x${string}` = await eesSDK.generateSponsorSignature(jobSpecification);
```

Here `jobSpecification` has type [`JobSpecification`](https://docs.ees.xyz/sdk/types). The returned value is an EIP-712 signature which can be used as input to creating a job.

{% hint style="info" %}
**Note:** A signature can only be redeemed by a single job. Providing an already redeemed signature when creating a job will cause the transaction to revert.

{% hint style="info" %}
**Note:** This action does not perform an on-chan transaction but still requires that `eesSDK` was initialised with a wallet client.
