# Paymaster Fees

**Paymaster Fees**

ChainEx is dedicated to crafting a sustainable and growth-oriented ecosystem. In addition to our tiered service plans, we have integrated strategic revenue streams to bolster our financial stability and provide added value to our users and token holders.

**Sponsored Transaction Fees**

* **Additional Fee**: Each transaction sponsored through our paymaster will incur a 10% surcharge on the gas fee. This premium is a direct source of revenue for ChainEx.
* **Flexibility**: Clients who prefer to use their own paymaster solutions can do so, thereby opting out of the 10% surcharge. This flexibility ensures that clients have control over their transaction costs while still benefiting from our robust SDK.
