boundNFTs
boundNFTs are promissory-note tokens that are minted and burned upon borrowing and repayment, representing the NFT used as collateral owed by the token holder, with the same token ID.
The boundNFTs' token is pegged to the token of the corresponding NFT collateral at a 1:1. All tokens owned by the boundNFTs holders can be simply integrated into the NFT wallet and social media.
The source code can be found on GitHub here.
For all minting and burning actions, see Borrow() and Repay() methods in the LendPool contract, and createLoan() and repayLoan() methods in the LendPoolLoan.
ERC721 Methods
Although boundNFT tokens are modeled on the ERC721 standard, they are non-transferable. Therefore they do not implement any of the standard ERC721 functions relating to transfer() and allowance().
Methods
mint
function mint(address to, uint256 tokenId)
Mints boundNFT token to the user address. The caller must have the original NFT of the underlying asset.
to
address
The owner address receive the boundNFT token
tokenId
uint256
The token id of the underlying asset of NFT
burn
function burn(uint256 tokenId)
Burns user boundNFT token. The caller must be the minter when it is minted.
tokenId
uint256
The token id of the underlying asset of NFT
flashLoan
function flashLoan( address receiverAddress, uint256[] calldata nftTokenIds, bytes calldata params )
Allows smart contracts to access the tokens within one transaction, as long as the tokens taken are returned. Only the NFT owner can do the flash loan for his owned NFTs.
receiverAddress
address
nftTokenIds
uint256[]
The token ids of the underlying asset
params
bytes
Variadic packed params to pass to the receiver as extra information
