Why was MetaStreet DAO created?
To expand the GDP of the Metaverse: The economy is the primary underpinning to the growth of any emergent world. MetaStreet was created to be the decentralized interest rate protocol for the Metaverse, built to autonomously grow the GDP of emerging virtual economies.
NFTs in and of themselves are not fungible, but their derivatives are. MetaStreet's capital vaults were invented to "fungify" NFT derivatives so as to abstract risk away from the underlying assets and scale capital participation. MetaStreet sits behind existing p2p marketplaces. The high level overview of this architecture can be seen in the video on Welcome to MetaStreet starting at 00:50.

Has MetaStreet been audited ?

Yes, Quantstamp and Halborn have all completed audits with no material issues found.

What are the fees to use MetaStreet vaults?

Currently, there are no fees with the vaults.
In the future, upon launch of decentralized governance, Capital Depositors will pay a fee of 20% of interest earned from a vault. This fee goes to the Vault Governors actively managing the vault in order to maximize earnings for the Capital Depositors. Note Originators do not pay a fee to sell notes into vaults.

Which NFT types are supported?

At launch, MetaStreet will support CryptoPunks and Bored Ape Yacht Club NFTs within the Avatar/DAI vault and the Avatar/ETH vault. Addition of new NFT types will be subject to a governance process.
What's the difference between MetaStreet Collateral Vaults and peer-to-protocol NFT lending?
The MetaStreet Collateral Vaults actually acquire p2p "promissory notes" that are created on p2p platforms like These promissory notes are fixed duration, fixed interest rate, and cannot be liquidated before the note matures. This construct provides certainty for the borrower, and allows the borrower to maintain composability of the underlying NFT as future use cases develop (ie, borrowing against an NFT while renting it out simultaneously).
This differs from a peer-to-protocol construct, where the NFT is largely treated as a fungible asset with real-time pricing and liquidations, similar to Aave / Compound / MakerDAO. In the peer-to-protocol approach, borrowers can get perpetual borrowing power, but are subject to variable interest rates and liquidation. This construct offers less composability for future use cases.
