# ComptrollerStorage ## ComptrollerStorage Storage layout for the `Comptroller` contract. ## Solidity API ```solidity struct LiquidationOrder { contract VToken vTokenCollateral; contract VToken vTokenBorrowed; uint256 repayAmount; } ``` ```solidity struct AccountLiquiditySnapshot { uint256 totalCollateral; uint256 weightedCollateral; uint256 borrows; uint256 effects; uint256 liquidity; uint256 shortfall; } ``` ```solidity struct RewardSpeeds { address rewardToken; uint256 supplySpeed; uint256 borrowSpeed; } ``` ```solidity struct Market { bool isListed; uint256 collateralFactorMantissa; uint256 liquidationThresholdMantissa; mapping(address => bool) accountMembership; } ``` ```solidity enum Action { MINT, REDEEM, BORROW, REPAY, SEIZE, LIQUIDATE, TRANSFER, ENTER_MARKET, EXIT_MARKET } ``` #### oracle Oracle which gives the price of any given asset ```solidity contract ResilientOracleInterface oracle ``` *** #### closeFactorMantissa Multiplier used to calculate the maximum repayAmount when liquidating a borrow ```solidity uint256 closeFactorMantissa ``` *** #### liquidationIncentiveMantissa Multiplier representing the discount on collateral that a liquidator receives ```solidity uint256 liquidationIncentiveMantissa ``` *** #### accountAssets Per-account mapping of "assets you are in" ```solidity mapping(address => contract VToken[]) accountAssets ``` *** #### markets Official mapping of vTokens -> Market metadata ```solidity mapping(address => struct ComptrollerStorage.Market) markets ``` *** #### allMarkets A list of all markets ```solidity contract VToken[] allMarkets ``` *** #### borrowCaps Borrow caps enforced by borrowAllowed for each vToken address. Defaults to zero which restricts borrowing. ```solidity mapping(address => uint256) borrowCaps ``` *** #### minLiquidatableCollateral Minimal collateral required for regular (non-batch) liquidations ```solidity uint256 minLiquidatableCollateral ``` *** #### supplyCaps Supply caps enforced by mintAllowed for each vToken address. Defaults to zero which corresponds to minting not allowed ```solidity mapping(address => uint256) supplyCaps ``` *** #### isForcedLiquidationEnabled Flag indicating whether forced liquidation enabled for a market ```solidity mapping(address => bool) isForcedLiquidationEnabled ``` *** #### prime Prime token address ```solidity contract IPrime prime ``` *** #### approvedDelegates Whether the delegate is allowed to borrow or redeem on behalf of the user ```solidity mapping(address => mapping(address => bool)) approvedDelegates ``` *** --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs-v4.venus.io/technical-reference/reference-isolated-pools/comptroller/comptroller-storage.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
