# Risk Management ![Risk Management Module](/files/i0ihbFAxy3OKJcU4XYYZ) **Risk Management** module monitors and restricts the asset flow by transactions. This consists of the functionalities as asset management and limition of risk factor. ## Asset Management `Asset Management` converts user's assets(ERC20) into factorial assets and give them to the app. This can prevent malicious losses by tracking the changes of the user assets. `Asset Management` of Factorial does not require the process of approval in order to remove the potential risk. ## Write Methods ### safeTransferFrom `function safeTransferFrom(address _from, address _to, uint256 _id, uint256 _amount, bytes memory _data)` This function override {ERC1155-safeTransferFrom}, while including tracking caller's input/outpunt asset & ERC20 converter. ### safeBatchTransferFrom `function safeBatchTransferFrom(address _from, address _to, uint256[] memory _ids, uint256[] memory _amounts, bytes memory _data)` This function override {ERC1155-safeBatchTransferFrom}, while including tracking caller's input/outpunt asset & ERC20 converter. ### safeTransferFrom `function safeTransferFrom(address _from, address _to, address _id, uint256 _amount)` Transfer with erc20 transfer. ## View Methods ### balanceOf `function balanceOf(address account, uint256 id) public view override returns (uint256)` If account is ERC20 holders, return ERC20 balance. Otherwise, return ERC1155 balance. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
