# Where does the yield come from?

The most common question people ask is *where does the upfront yield come from?*

It is important to note the Flashstake Protocol is *not* responsible for generating yield as all upfront yield is made available at the [Time Vault Strategy](https://docs.flashstake.io/time-vault-strategies-tvs) level.

### **Pools**

Ultimately, Time Vaults use multiple methods of "Pools" to make upfront yield possible. Here are three of the current most used pool types that enable upfront yield.

* Yield Pools
* Liquidity Pools
* Boost Pools
