NFT+DeFi in NFTfi. Put your NFT assets up as collateral for a loan, or offer loans to other users on their NFTs in NFTfi. List any ERC-721 as collateral. Other users can now offer you a loan. If you accept a loan, the ETH gets paid out from the lenders account to you, and your NFT gets locked in the NFTfi smart contract. Once you repay the loan the asset will be sent back to you. If you don’t pay back the total repayment amount before the due date, the asset will be sent to the lender.
