Two vaults are insufficient liquidity:

At present, these two vaults cannot be operated, which seriously affects the user experience.

A possible solution:

1.Allow user to stake WETH to borrow NFT. Using pair price as pricefeed. Liquidate according to a certain mortgage rate if NFT's price rise.(collateral owe to protocol)

A feature of the borrowing in NFTX is the user only need to return NFT belonging to this collection, a same one is not necessary.(NFTX only need to operate the floor price) It is much more simple than similar protocol.

After it, we created cash flow.

1.1

We could allow user stake NFT to borrow WETH to created bigger cash flow.

2.

Using cash flow, protocol could take the initiative to buy and sell. This can solve the problem that the vault is closed due to insufficient liquidity and user experience is better.
