The contract is serving as the underlying entity to interact with one or more third party protocols. The scope of the audit treats third party entities as black boxes and assume their functional correctness. However, in the real world, third parties can be compromised and this may lead to lost or stolen assets. In addition, upgrades of third parties can possibly create severe impacts, such as increasing fees of third parties, migrating to new LP pools, etc. --- ```solidity=64 function createUserRecord(RecordParam memory param) external { ``` - The function `Bank1155.createUserRecord` interacts with third party contract with `IERC1155` interface via `param`. --- ```solidity=105 function _deleteUserRecord(RentingRecord calldata param) internal { ``` - The function `Bank1155._deleteUserRecord` interacts with third party contract with `IERC1155` interface via `param`. --- ```solidity=21 address oNFT, ``` - The function `Bank721.tryStakeNFT721` interacts with third party contract with `IERC721` interface via `oNFT`. --- ```solidity=39 address oNFT, ``` - The function `Bank721.redeemNFT721` interacts with third party contract with `IERC721` interface via `oNFT`. --- ```solidity=20 mapping(address => address) public oNFT_w4907; ``` - The contract `W4907Factory` interacts with third party contract with `IWrapNFT` interface via `oNFT_w4907`. --- ```solidity=70 address w4907 ``` - The function `W4907Factory.registerW4907` interacts with third party contract with `IWrapNFT` interface via `w4907`. --- ```solidity=31 function deployW5006(address oNFT) public { ``` - The function `W5006Factory.deployW5006` interacts with third party contract with `IERC1155` interface via `oNFT`. --- ```solidity=38 function registerW5006(address oNFT, address w5006) public onlyAdmin { ``` - The function `W5006Factory.registerW5006` interacts with third party contract with `IWrappedInERC5006` interface via `w5006`.
