# Protocol Revenue

### Velora sources of revenue

There are currently two main types of revenue for Velora: 

#### **Swap fees**

**When accessing through a Partner**, it's **up to the Partner** to decide if they want to charge a fee on the swaps facilitated through Augustus Swapper (Market Mode) or Velora Delta. If opting for Augustus, Velora DAO collects 15% of the accrued swap fee, while in Delta, fee splitting only happens for surplus-generating swaps.

For more information on how Swap Fees are implemented, please refer to the [API Partners - Revenue Share Overview](https://docs.velora.xyz/integrating-velora/integrating-velora-overview/fee-sharing#partners-fees-overview) Section.
{% endhint %}

#### Surplus

Another potential fee to consider is **Surplus**: the decentralized markets are always on the move; sometimes, competing transactions can push the price lower (or higher) after submitting the transaction**.** Velora implements several mechanisms to hedge for it, such as displaying the "Minimum Received" amount or securing prices for a set amount of time with market makers quoting through AugustusRFQ.

**Velora DAO collects the surplus to grow further and perpetuate the protocol**. By default, in Market Mode, Velora DAO collects 100% of the surplus generated, while in Delta Mode, the DAO collects 50%.

Partners who opt out of charging a Partner Swap Fee can choose to keep 50% of the surplus or direct it to the user, paid in the destination token.
