There are many advantages for doing so such as:
“Blue-chip” collections are more accessible for mainstream collectors (you might not have 20 ETH to buy a MAYC but you do have 5 ETH to buy 25% of it)
You can sell your ownership share on Opensea (and other marketplaces) immediately and don’t need liquidity in an ERC20 pool nor relying on arbitrageurs to fix the discrepancies between the market cap of the ERC20 and the collection floor price
As oppose to other platforms, our vaults allow listing and buying NFTs directly on Opensea rather than needing to auction on Fractional
You can use your share NFT (it looks like the original NFT just with % strip) as a PFP and flex that you own 50% of a BAYC
You can split your high end NFT (1000 ETH+) to X parts and sell them on Opensea
Projects can grow their community by offering benefits (i.e joining discord) to holders that have more than x% ownership in the project’s NFT
Furthermore, as far as we know, the NFT vault is the first product that allows a group of people to buy and sell NFTs on Opensea.
Create a vault

Deposit some ETH

Select NFT to sale from the collection of the vault

Other participants deposit more ETH and vote for or against buying this specific NFT

When the buy consensus has passed, the vault is ready to buy from Opensea

The vault has purchased the NFT

After the vault purchased the NFT, participants can claim their share

This is what the ownership share NFT looks like

Set a listing price and participants vote for selling the NFT

The vault has listed the NFT for sale on Opensea for 0.3 ETH

After the NFT was sold on Opensea participants can redeem their share to claim the ETH from the sale

Shares that are not redeemed change their image & properties and are not tradable on Opensea anymore to protect the seller/buyer

This is a quick overview of the NFT vault and we hope you like it :)
The NFT vault is one product under The Collectors brand. Stay tuned for additional product release in Q3!
