# Rental Solutions

- [Collateral-Free](/rental-solutions/collateral-free.md): Lender's NFT gets staked into our smart contract and is not transferred to renter. Integrating projects use our API to obtain the list of renters.
- [Collateralized](/rental-solutions/collateralized.md): We advise against using this solution, because collateral is a huge barrier to entry. However, should you wish to lend / rent, there is no integration required.
