# Infinite combination of DeFi primitives

Hedge vaults allow you to create custom structured financial products by combining Rumi’s own lending primitive and the primitives of external DeFi protocols:

* **Rumi’s under-collateralized lending (Rumi Prime)**: Rumi has built a prime brokerage module that is able to provide vaults with pseudo delta-neutral capabilities and to more precisely manage leverage needs across the Rumi platform.
* **Integrations with external protocols:**
  * **Money markets**: over-collateralised lending and borrowing protocols such as AAVE, Morpho and Maker.
  * **Liquid (re-)staking**: integrations with liquid staking and re-staking protocols such as Lido, Rocket Pool, [Ether.fi](http://ether.fi), Swell, Unsheeth, etc.
  * **Liquidity provision**: LPing on constant function and concentrated liquidity AMMs as well as perpetual futures protocols including Uniswap V3 and GMX.
  * **Options**: hedge vaults can integrate with the main options protocols in order to generate premiums, hedge options and create advanced structured financial products. These protocols include Deribit, Paradigm, Aevo, Lyra.
