Title: ERC-721 Portal interface

Functions

depositErc721Token

Transfer an ERC-721 token to an application contract and add an input to the application's input box to signal such operation. The caller must change the approved address for the ERC-721 token to the portal address beforehand, by calling the approve function in the token contract.

If the application is foreclosed, and the deposit input is not processed, the user can issue a refund. If the user deposits an NFT through a smart contract, a refund will only succeed if the smart contract accepts it through the onERC721Received callback. If the smart contract wallet does not accept the NFT through the callback, it may not be recoverable.

    IERC721 token,
    address appContract,
