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.", "kind": "dev", diff --git

@title Comptroller\\n * @author Venus\\n * @notice The Comptroller is designed to provide checks for all minting, redeeming, transferring, borrowing, lending, repaying, liquidating,\\n * and seizing done by the `vToken` contract. Each pool has one `Comptroller` checking these interactions across markets. When a user interacts\\n * with a given market by one of these main actions, a call is made to a corresponding hook in the associated `Comptroller`, which either allows\\n * or reverts the transaction. These hooks also update supply and borrow rewards as they are called. The comptroller holds the logic for assessing\\n * liquidity snapshots of an account via the collateral factor and liquidation threshold. This check determines the collateral needed for a borrow,\\n * as well as how much of a borrow may be liquidated. A user may borrow a portion of their collateral with the maximum amount determined by the\\n * markets collateral factor. However, if their borrowed amount exceeds an amount calculated using the market\\u2019s corresponding liquidation threshold,\\n * the borrow is eligible for liquidation.\\n *\\n * The `Comptroller` also includes two functions `liquidateAccount()` and `healAccount()`, which are meant to handle accounts that do not exceed\\n * the `minLiquidatableCollateral` for the `Comptroller`:\\n *\\n * - `healAccount()`: This function is called to seize all of a given user\\u2019s collateral, requiring the `msg.sender` repay a certain percentage\\n * of the debt calculated by `collateral/(borrows*liquidationIncentive)`. The function can only be called if the calculated percentage does not exceed\\n * 100%, because otherwise no `badDebt` would be created and `liquidateAccount()` should be used instead. The difference in the actual amount of debt\\n * and debt paid off is recorded as `badDebt` for each market, which can then be auctioned off for the risk reserves of the associated pool.\\n * - `liquidateAccount()`: This function can only be called if the collateral seized will cover all borrows of an account, as well as the liquidation\\n * incentive. Otherwise, the pool will incur bad debt, in which case the function `healAccount()` should be used instead. This function skips the logic\\n * verifying that the repay amount does not exceed the close factor.\\n */\\ncontract Comptroller is\\n Ownable2StepUpgradeable,\\n AccessControlledV8,\\n ComptrollerStorage,\\n ComptrollerInterface,\\n ExponentialNoError,\\n MaxLoopsLimitHelper\\n{\\n // PoolRegistry, immutable to save on gas\\n /// @custom:oz-upgrades-unsafe-allow state-variable-immutable\\n address public immutable poolRegistry;\\n\\n /// @notice Emitted when an account enters a market\\n event MarketEntered(VToken indexed vToken, address indexed account);\\n\\n /// @notice Emitted when an account exits a market\\n event MarketExited(VToken indexed vToken, address indexed account);\\n\\n /// @notice Emitted when close factor is changed by admin\\n event NewCloseFactor(uint256 oldCloseFactorMantissa, uint256 newCloseFactorMantissa);\\n\\n /// @notice Emitted when a collateral factor is changed by admin\\n event NewCollateralFactor(VToken vToken, uint256 oldCollateralFactorMantissa, uint256 newCollateralFactorMantissa);\\n\\n /// @notice Emitted when liquidation threshold is changed by admin\\n event NewLiquidationThreshold(\\n VToken vToken,\\n uint256 oldLiquidationThresholdMantissa,\\n uint256 newLiquidationThresholdMantissa\\n );\\n\\n /// @notice Emitted when liquidation incentive is changed by admin\\n event NewLiquidationIncentive(uint256 oldLiquidationIncentiveMantissa, uint256 newLiquidationIncentiveMantissa);\\n\\n /// @notice Emitted when price oracle is changed\\n event NewPriceOracle(ResilientOracleInterface oldPriceOracle, ResilientOracleInterface newPriceOracle);\\n\\n /// @notice Emitted when an action is paused on a market\\n event ActionPausedMarket(VToken vToken, Action action, bool pauseState);\\n\\n /// @notice Emitted when borrow cap for a vToken is changed\\n event NewBorrowCap(VToken indexed vToken, uint256 newBorrowCap);\\n\\n /// @notice Emitted when the collateral threshold (in USD) for non-batch liquidations is changed\\n event NewMinLiquidatableCollateral(uint256 oldMinLiquidatableCollateral, uint256 newMinLiquidatableCollateral);\\n\\n /// @notice Emitted when supply cap for a vToken is changed\\n event NewSupplyCap(VToken indexed vToken, uint256 newSupplyCap);\\n\\n /// @notice Emitted when a rewards distributor is added\\n event NewRewardsDistributor(address indexed rewardsDistributor);\\n\\n /// @notice Emitted when a market is supported\\n event MarketSupported(VToken vToken);\\n\\n /// @notice Thrown when collateral factor exceeds the upper bound\\n error InvalidCollateralFactor();\\n\\n /// @notice Thrown when liquidation threshold exceeds the collateral factor\\n error InvalidLiquidationThreshold();\\n\\n /// @notice Thrown when the action is only available to specific sender, but the real sender was different\\n error UnexpectedSender(address expectedSender, address actualSender);\\n\\n /// @notice Thrown when the oracle returns an invalid price for some asset\\n error PriceError(address vToken);\\n\\n /// @notice Thrown if VToken unexpectedly returned a nonzero error code while trying to get account snapshot\\n error SnapshotError(address vToken, address user);\\n\\n /// @notice Thrown when the market is not listed\\n error MarketNotListed(address market);\\n\\n /// @notice Thrown when a market has an unexpected comptroller\\n error ComptrollerMismatch();\\n\\n /// @notice Thrown when user is not member of market\\n error MarketNotCollateral(address vToken, address user);\\n\\n /**\\n * @notice Thrown during the liquidation if user's total collateral amount is lower than\\n * a predefined threshold.

`VToken` contract. As outlined in the protocol overview,\\n * each isolated pool creates its own `vToken` corresponding to an asset. Within a given pool, each included `vToken` is referred to as a market of\\n * the pool. The main actions a user regularly interacts with in a market are:\\n\\n- mint/redeem of vTokens;\\n- transfer of vTokens;\\n- borrow/repay a loan on an underlying asset;\\n- liquidate a borrow or liquidate/heal an account.\\n\\n * A user supplies the underlying asset to a pool by minting `vTokens`, where the corresponding `vToken` amount is determined by the `exchangeRate`.\\n * The `exchangeRate` will change over time, dependent on a number of factors, some of which accrue interest. Additionally, once users have minted\\n * `vToken` in a pool, they can borrow any asset in the isolated pool by using their `vToken` as collateral. In order to borrow an asset or use a `vToken`\\n * as collateral, the user must be entered into each corresponding market (else, the `vToken` will not be considered collateral for a borrow). Note that\\n * a user may borrow up to a portion of their collateral determined by the market\\u2019s collateral factor. However, if their borrowed amount exceeds an amount\\n * calculated using the market\\u2019s corresponding liquidation threshold, the borrow is eligible for liquidation. When a user repays a borrow, they must also\\n * pay off interest accrued on the borrow.\\n * \\n * The Venus protocol includes unique mechanisms for healing an account and liquidating an account. These actions are performed in the `Comptroller`\\n * and consider all borrows and collateral for which a given account is entered within a market. These functions may only be called on an account with a\\n * total collateral amount that is no larger than a universal `minLiquidatableCollateral` value, which is used for all markets within a `Comptroller`.\\n * Both functions settle all of an account\\u2019s borrows, but `healAccount()` may add `badDebt` to a vToken. For more detail, see the description of\\n * `healAccount()` and `liquidateAccount()` in the `Comptroller` summary section below.\\n */\\ncontract VToken is\\n Ownable2StepUpgradeable,\\n AccessControlledV8,\\n VTokenInterface,\\n ExponentialNoError,\\n TokenErrorReporter\\n{\\n using SafeERC20Upgradeable for IERC20Upgradeable;\\n\\n uint256 internal constant DEFAULT_PROTOCOL_SEIZE_SHARE_MANTISSA = 5e16; // 5%\\n\\n /*** Reentrancy Guard ***/\\n\\n /**\\n * @dev Prevents a contract from calling itself, directly or indirectly.\\n */\\n modifier nonReentrant() {\\n require(_notEntered, \\\"re-entered\\\");\\n _notEntered = false;\\n _;\\n _notEntered = true; // get a gas-refund post-Istanbul\\n }\\n\\n /// @custom:oz-upgrades-unsafe-allow constructor\\n constructor() {\\n // Note that the contract is upgradeable.

Authorized users can set the reward token borrow and supply speeds for each market in the pool. This sets a fixed amount of reward token to be released each block for borrowers and suppliers, which is distributed based on a user’s percentage of the borrows or supplies respectively. The owner can also set up reward distributions to contributor addresses (distinct from suppliers and borrowers) by setting their contributor reward token speed, which similarly allocates a fixed amount of reward token per block. The owner has the ability to transfer any amount of reward tokens held by the contract to any other address. Rewards are not distributed automatically and must be claimed by a user calling `claimRewardToken()`.
