TERC721
TERC721 are promissory-note tokens that are minted and burned upon deposite nft and withdraw nft, representing the NFT used as collateral owed by the token holder, with the same token ID.
The TERC721 token is pegged to the token of the corresponding NFT collateral at a 1:1. All tokens owned by the TERC721 holders can be simply integrated into the NFT wallet and social media.
For all minting and burning actions, see depositNFTs() and withdrawNFTs() methods in the LendingPool contract.
TERC721 implements all the standard interfaces of ERC721. Transferring TERC721 to others is only allowed when the lending situation of TERC721 holders remains healthy.
