LEND721 is Ethereum Smart Contract that allows lending ERC-721 Smart Contracts (NFT) and gain interest from it. On the other hand it allows to borrow same NFT's that are set for lending by paying collateral to LEND721 which handles the lend process.
Current stage: beta.
- Mainnet: https://lend721.app
- Rinkeby: https://rinkeby.lend721.app
- Mainnet: 0xA133541435cAeB964f572132acd8FEAC3Ed1D80B
- Rinkeby: 0x1762fd547d6C286a174dD62b6A6fACFAc064A0A0
Note: Smart Contract calls are proxied to main Smart Contract so calls destination is the Proxy Smart Contract itself.
