     "details": "This contract implements a proxy that is upgradeable by an admin. To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector clashing], which can potentially be used in an attack, this contract uses the https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two things that go hand in hand: 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if that call matches one of the admin functions exposed by the proxy itself. 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the implementation. If the admin tries to call a function on the implementation it will fail with an error that says \"admin cannot fallback to proxy target\". These properties mean that the admin account can only be used for admin actions like upgrading the proxy or changing the admin, so it's best if it's a dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to call a function from the proxy implementation. Our recommendation is for the dedicated account to be an instance of the {ProxyAdmin} contract. If set up this way, you should think of the `ProxyAdmin` instance as the real administrative interface of your proxy.",

Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an\\n * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer\\n * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\\n *\\n * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be\\n * reused. This mechanism prevents re-execution of each \\\"step\\\" but allows the creation of new initialization steps in\\n * case an upgrade adds a module that needs to be initialized.\\n *\\n * For example:\\n *\\n * [.hljs-theme-light.nopadding]\\n * ```solidity\\n * contract MyToken is ERC20Upgradeable {\\n *     function initialize() initializer public {\\n *         __ERC20_init(\\\"MyToken\\\", \\\"MTK\\\");\\n *     }\\n * }\\n *\\n * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\\n *     function initializeV2() reinitializer(2) public {\\n *         __ERC20Permit_init(\\\"MyToken\\\");\\n *     }\\n * }\\n * ```\\n *\\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\\n * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\\n *\\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\\n * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\\n *\\n * [CAUTION]\\n * ====\\n * Avoid leaving a contract uninitialized.\\n *\\n * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\\n * contract, which may impact the proxy.

Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an\\n * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer\\n * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\\n *\\n * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be\\n * reused. This mechanism prevents re-execution of each \\\"step\\\" but allows the creation of new initialization steps in\\n * case an upgrade adds a module that needs to be initialized.\\n *\\n * For example:\\n *\\n * [.hljs-theme-light.nopadding]\\n * ```solidity\\n * contract MyToken is ERC20Upgradeable {\\n *     function initialize() initializer public {\\n *         __ERC20_init(\\\"MyToken\\\", \\\"MTK\\\");\\n *     }\\n * }\\n *\\n * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\\n *     function initializeV2() reinitializer(2) public {\\n *         __ERC20Permit_init(\\\"MyToken\\\");\\n *     }\\n * }\\n * ```\\n *\\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\\n * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\\n *\\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\\n * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\\n *\\n * [CAUTION]\\n * ====\\n * Avoid leaving a contract uninitialized.\\n *\\n * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\\n * contract, which may impact the proxy.

Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an\n * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer\n * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\n *\n * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be\n * reused. This mechanism prevents re-execution of each \"step\" but allows the creation of new initialization steps in\n * case an upgrade adds a module that needs to be initialized.\n *\n * For example:\n *\n * [.hljs-theme-light.nopadding]\n * ```solidity\n * contract MyToken is ERC20Upgradeable {\n *     function initialize() initializer public {\n *         __ERC20_init(\"MyToken\", \"MTK\");\n *     }\n * }\n *\n * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\n *     function initializeV2() reinitializer(2) public {\n *         __ERC20Permit_init(\"MyToken\");\n *     }\n * }\n * ```\n *\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\n * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\n *\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\n * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\n *\n * [CAUTION]\n * ====\n * Avoid leaving a contract uninitialized.\n *\n * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\n * contract, which may impact the proxy.

It then becomes necessary to protect this initializer\n * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\n *\n * The initialization functions use a version number.

It is used to restrict functions so that they can only be called from one\n * account or list of accounts (EOA or Contract Accounts).\n *\n * The implementation of `AccessControlManager`(https://github.com/VenusProtocol/governance-contracts/blob/main/contracts/Governance/AccessControlManager.sol)\n * inherits the [Open Zeppelin AccessControl](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/access/AccessControl.sol)\n * contract as a base for role management logic. There are two role types: admin and granular permissions.\n * \n * ## Granular Roles\n * \n * Granular roles are built by hashing the contract address and its function signature. For example, given contract `Foo` with function `Foo.bar()` which\n * is guarded by ACM, calling `giveRolePermission` for account B do the following:\n * \n * 1. Compute `keccak256(contractFooAddress,functionSignatureBar)`\n * 1. Add the computed role to the roles of account B\n * 1. Account B now can call `ContractFoo.bar()`\n * \n * ## Admin Roles\n * \n * Admin roles allow for an address to call a function signature on any contract guarded by the `AccessControlManager`. This is particularly useful for\n * contracts created by factories.\n * \n * For Admin roles a null address is hashed in place of the contract address (`keccak256(0x0000000000000000000000000000000000000000,functionSignatureBar)`.\n * \n * In the previous example, giving account B the admin role, account B will have permissions to call the `bar()` function on any contract that is guarded by\n * ACM, not only contract A.\n * \n * ## Protocol Integration\n * \n * All restricted functions in Venus Protocol use a hook to ACM in order to check if the caller has the right permission to call the guarded function.\n * `AccessControlledV5` and `AccessControlledV8` abstract contract makes this integration easier. They call ACM's external method\n * `isAllowedToCall(address caller, string functionSig)`. Here is an example of how `setCollateralFactor` function in `Comptroller` is integrated with ACM:\n\n```\n    contract Comptroller is [...] AccessControlledV8 {\n        [...]\n        function setCollateralFactor(VToken vToken, uint256 newCollateralFactorMantissa, uint256 newLiquidationThresholdMantissa) external {\n            _checkAccessAllowed(\"setCollateralFactor(address,uint256,uint256)\");\n            [...]\n        }\n    }\n```\n */\ncontract AccessControlManager is AccessControl, IAccessControlManagerV8 {\n    /// @notice Emitted when an account is given a permission to a certain contract function\n    /// @dev If contract address is 0x000..0 this means that the account is a default admin of this function and\n    /// can call any contract function with this signature\n    event PermissionGranted(address account, address contractAddress, string functionSig);\n\n    /// @notice Emitted when an account is revoked a permission to a certain contract function\n    event PermissionRevoked(address account, address contractAddress, string functionSig);\n\n    constructor() {\n        // Grant the contract deployer the default admin role: it will be able\n        // to grant and revoke any roles\n        _setupRole(DEFAULT_ADMIN_ROLE, msg.sender);\n    }\n\n    /**\n     * @notice Gives a function call permission to one single account\n     * @dev this function can be called only from Role Admin or DEFAULT_ADMIN_ROLE\n     * @param contractAddress address of contract for which call permissions will be granted\n     * @dev if contractAddress is zero address, the account can access the specified function\n     *      on **any** contract managed by this ACL\n     * @param functionSig signature e.g. \"functionName(uint256,bool)\"\n     * @param accountToPermit account that will be given access to the contract function\n     * @custom:event Emits a {RoleGranted} and {PermissionGranted} events.\n     */\n    function giveCallPermission(address contractAddress, string calldata functionSig, address accountToPermit) public {\n        bytes32 role = keccak256(abi.encodePacked(contractAddress, functionSig));\n        grantRole(role, accountToPermit);\n        emit PermissionGranted(accountToPermit, contractAddress, functionSig);\n    }\n\n    /**\n     * @notice Revokes an account's permission to a particular function call\n     * @dev this function can be called only from Role Admin or DEFAULT_ADMIN_ROLE\n     * \t\tMay emit a {RoleRevoked} event.\n     * @param contractAddress address of contract for which call permissions will be revoked\n     * @param functionSig signature e.g. \"functionName(uint256,bool)\"\n     * @custom:event Emits {RoleRevoked} and {PermissionRevoked} events.\n     */\n    function revokeCallPermission(\n        address contractAddress,\n        string calldata functionSig,\n        address accountToRevoke\n    ) public {\n        bytes32 role = keccak256(abi.encodePacked(contractAddress, functionSig));\n        revokeRole(role, accountToRevoke);\n        emit PermissionRevoked(accountToRevoke, contractAddress, functionSig);\n    }\n\n    /**\n     * @notice Verifies if the given account can call a contract's guarded function\n     * @dev Since restricted contracts using this function as a permission hook, we can get contracts address with msg.sender\n     * @param account for which call permissions will be checked\n     * @param functionSig restricted function signature e.g. \"functionName(uint256,bool)\"\n     * @return false if the user account cannot call the particular contract function\n     *\n     */\n    function isAllowedToCall(address account, string calldata functionSig) public view returns (bool) {\n        bytes32 role = keccak256(abi.encodePacked(msg.sender, functionSig));\n\n        if (hasRole(role, account)) {\n            return true;\n        } else {\n            role = keccak256(abi.encodePacked(address(0), functionSig));\n            return hasRole(role, account);\n        }\n    }\n\n    /**\n     * @notice Verifies if the given account can call a contract's guarded function\n     * @dev This function is used as a view function to check permissions rather than contract hook for access restriction check.\n     * @param account for which call permissions will be checked against\n     * @param contractAddress address of the restricted contract\n     * @param functionSig signature of the restricted function e.g. \"functionName(uint256,bool)\"\n     * @return false if the user account cannot call the particular contract function\n     */\n    function hasPermission(\n        address account,\n        address contractAddress,\n        string calldata functionSig\n    ) public view returns (bool) {\n        bytes32 role = keccak256(abi.encodePacked(contractAddress, functionSig));\n        return hasRole(role, account);\n    }\n}\n"

     "details": "This contract implements a proxy that is upgradeable by an admin. To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector clashing], which can potentially be used in an attack, this contract uses the https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two things that go hand in hand: 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if that call matches one of the admin functions exposed by the proxy itself. 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the implementation. If the admin tries to call a function on the implementation it will fail with an error that says \"admin cannot fallback to proxy target\". These properties mean that the admin account can only be used for admin actions like upgrading the proxy or changing the admin, so it's best if it's a dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to call a function from the proxy implementation. Our recommendation is for the dedicated account to be an instance of the {ProxyAdmin} contract. If set up this way, you should think of the `ProxyAdmin` instance as the real administrative interface of your proxy.",

Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an\\n * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer\\n * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\\n *\\n * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be\\n * reused. This mechanism prevents re-execution of each \\\"step\\\" but allows the creation of new initialization steps in\\n * case an upgrade adds a module that needs to be initialized.\\n *\\n * For example:\\n *\\n * [.hljs-theme-light.nopadding]\\n * ```solidity\\n * contract MyToken is ERC20Upgradeable {\\n *     function initialize() initializer public {\\n *         __ERC20_init(\\\"MyToken\\\", \\\"MTK\\\");\\n *     }\\n * }\\n *\\n * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\\n *     function initializeV2() reinitializer(2) public {\\n *         __ERC20Permit_init(\\\"MyToken\\\");\\n *     }\\n * }\\n * ```\\n *\\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\\n * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\\n *\\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\\n * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\\n *\\n * [CAUTION]\\n * ====\\n * Avoid leaving a contract uninitialized.\\n *\\n * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\\n * contract, which may impact the proxy.

This mechanism prevents re-execution of each \"step\" but allows the creation of new initialization steps in\n * case an upgrade adds a module that needs to be initialized.\n *\n * For example:\n *\n * [.hljs-theme-light.nopadding]\n * ```solidity\n * contract MyToken is ERC20Upgradeable {\n *     function initialize() initializer public {\n *         __ERC20_init(\"MyToken\", \"MTK\");\n *     }\n * }\n *\n * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\n *     function initializeV2() reinitializer(2) public {\n *         __ERC20Permit_init(\"MyToken\");\n *     }\n * }\n * ```\n *\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\n * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\n *\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\n * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\n *\n * [CAUTION]\n * ====\n * Avoid leaving a contract uninitialized.\n *\n * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\n * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke\n * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:\n *\n * [.hljs-theme-light.nopadding]\n * ```\n * /// @custom:oz-upgrades-unsafe-allow constructor\n * constructor() {\n *     _disableInitializers();\n * }\n * ```\n * ====\n */\nabstract contract Initializable {\n    /**\n     * @dev Indicates that the contract has been initialized.\n     * @custom:oz-retyped-from bool\n     */\n    uint8 private _initialized;\n\n    /**\n     * @dev Indicates that the contract is in the process of being initialized.\n     */\n    bool private _initializing;\n\n    /**\n     * @dev Triggered when the contract has been initialized or reinitialized.\n     */\n    event Initialized(uint8 version);\n\n    /**\n     * @dev A modifier that defines a protected initializer function that can be invoked at most once.

It then becomes necessary to protect this initializer\n * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\n *\n * The initialization functions use a version number.

It is used to restrict functions so that they can only be called from one\n * account or list of accounts (EOA or Contract Accounts).\n *\n * The implementation of `AccessControlManager`(https://github.com/VenusProtocol/governance-contracts/blob/main/contracts/Governance/AccessControlManager.sol)\n * inherits the [Open Zeppelin AccessControl](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/access/AccessControl.sol)\n * contract as a base for role management logic. There are two role types: admin and granular permissions.\n * \n * ## Granular Roles\n * \n * Granular roles are built by hashing the contract address and its function signature. For example, given contract `Foo` with function `Foo.bar()` which\n * is guarded by ACM, calling `giveRolePermission` for account B do the following:\n * \n * 1. Compute `keccak256(contractFooAddress,functionSignatureBar)`\n * 1. Add the computed role to the roles of account B\n * 1. Account B now can call `ContractFoo.bar()`\n * \n * ## Admin Roles\n * \n * Admin roles allow for an address to call a function signature on any contract guarded by the `AccessControlManager`. This is particularly useful for\n * contracts created by factories.\n * \n * For Admin roles a null address is hashed in place of the contract address (`keccak256(0x0000000000000000000000000000000000000000,functionSignatureBar)`.\n * \n * In the previous example, giving account B the admin role, account B will have permissions to call the `bar()` function on any contract that is guarded by\n * ACM, not only contract A.\n * \n * ## Protocol Integration\n * \n * All restricted functions in Venus Protocol use a hook to ACM in order to check if the caller has the right permission to call the guarded function.\n * `AccessControlledV5` and `AccessControlledV8` abstract contract makes this integration easier. They call ACM's external method\n * `isAllowedToCall(address caller, string functionSig)`. Here is an example of how `setCollateralFactor` function in `Comptroller` is integrated with ACM:\n\n```\n    contract Comptroller is [...] AccessControlledV8 {\n        [...]\n        function setCollateralFactor(VToken vToken, uint256 newCollateralFactorMantissa, uint256 newLiquidationThresholdMantissa) external {\n            _checkAccessAllowed(\"setCollateralFactor(address,uint256,uint256)\");\n            [...]\n        }\n    }\n```\n */\ncontract AccessControlManager is AccessControl, IAccessControlManagerV8 {\n    /// @notice Emitted when an account is given a permission to a certain contract function\n    /// @dev If contract address is 0x000..0 this means that the account is a default admin of this function and\n    /// can call any contract function with this signature\n    event PermissionGranted(address account, address contractAddress, string functionSig);\n\n    /// @notice Emitted when an account is revoked a permission to a certain contract function\n    event PermissionRevoked(address account, address contractAddress, string functionSig);\n\n    constructor() {\n        // Grant the contract deployer the default admin role: it will be able\n        // to grant and revoke any roles\n        _setupRole(DEFAULT_ADMIN_ROLE, msg.sender);\n    }\n\n    /**\n     * @notice Gives a function call permission to one single account\n     * @dev this function can be called only from Role Admin or DEFAULT_ADMIN_ROLE\n     * @param contractAddress address of contract for which call permissions will be granted\n     * @dev if contractAddress is zero address, the account can access the specified function\n     *      on **any** contract managed by this ACL\n     * @param functionSig signature e.g. \"functionName(uint256,bool)\"\n     * @param accountToPermit account that will be given access to the contract function\n     * @custom:event Emits a {RoleGranted} and {PermissionGranted} events.\n     */\n    function giveCallPermission(address contractAddress, string calldata functionSig, address accountToPermit) public {\n        bytes32 role = keccak256(abi.encodePacked(contractAddress, functionSig));\n        grantRole(role, accountToPermit);\n        emit PermissionGranted(accountToPermit, contractAddress, functionSig);\n    }\n\n    /**\n     * @notice Revokes an account's permission to a particular function call\n     * @dev this function can be called only from Role Admin or DEFAULT_ADMIN_ROLE\n     * \t\tMay emit a {RoleRevoked} event.\n     * @param contractAddress address of contract for which call permissions will be revoked\n     * @param functionSig signature e.g. \"functionName(uint256,bool)\"\n     * @custom:event Emits {RoleRevoked} and {PermissionRevoked} events.\n     */\n    function revokeCallPermission(\n        address contractAddress,\n        string calldata functionSig,\n        address accountToRevoke\n    ) public {\n        bytes32 role = keccak256(abi.encodePacked(contractAddress, functionSig));\n        revokeRole(role, accountToRevoke);\n        emit PermissionRevoked(accountToRevoke, contractAddress, functionSig);\n    }\n\n    /**\n     * @notice Verifies if the given account can call a contract's guarded function\n     * @dev Since restricted contracts using this function as a permission hook, we can get contracts address with msg.sender\n     * @param account for which call permissions will be checked\n     * @param functionSig restricted function signature e.g. \"functionName(uint256,bool)\"\n     * @return false if the user account cannot call the particular contract function\n     *\n     */\n    function isAllowedToCall(address account, string calldata functionSig) public view returns (bool) {\n        bytes32 role = keccak256(abi.encodePacked(msg.sender, functionSig));\n\n        if (hasRole(role, account)) {\n            return true;\n        } else {\n            role = keccak256(abi.encodePacked(address(0), functionSig));\n            return hasRole(role, account);\n        }\n    }\n\n    /**\n     * @notice Verifies if the given account can call a contract's guarded function\n     * @dev This function is used as a view function to check permissions rather than contract hook for access restriction check.\n     * @param account for which call permissions will be checked against\n     * @param contractAddress address of the restricted contract\n     * @param functionSig signature of the restricted function e.g. \"functionName(uint256,bool)\"\n     * @return false if the user account cannot call the particular contract function\n     */\n    function hasPermission(\n        address account,\n        address contractAddress,\n        string calldata functionSig\n    ) public view returns (bool) {\n        bytes32 role = keccak256(abi.encodePacked(contractAddress, functionSig));\n        return hasRole(role, account);\n    }\n}\n"
