Controller

The Controller is the risk management portal of the dForce Lending & Synthetic Protocol, it determines how much collateral a user is required to maintain, whether (and how much) a user can be liquidated, and control the protocol risk by adjusting supply/borrow capacity and risk parameters.

Methods

enterMarkets()

Enter into a list of markets. In order to supply collateral or borrow in a market, it must be entered first.
function enterMarkets(address[] calldata iTokens)
external
returns (bool[] memory);

exitMarkets()

Exit a market, exited markets will not count towards account liquidity calculations.
function exitMarkets(address[] calldata iTokens)
external
returns (bool[] memory);

getAlliTokens()

Get all markets already added into the protocol.
function getAlliTokens() external view returns (address[] memory);

hasiToken()

Return the status whether an iToken is listed in the controller.
function hasiToken(address _iToken) external view returns (bool);

getEnteredMarkets()

Get all markets already entered from one account.
function getEnteredMarkets(address account)
external
view
returns (address[] memory);

getBorrowedAssets()

Get all assets already borrowed from one account.
function getBorrowedAssets(address account)
external
view
returns (address[] memory);

calcAccountEquity()

Account liquidity represents the USD value with the specific asset/amount-continue-redeeming or amount-continue-borrowing before it reaches liquidation. Returns Tuple of values (equity, shortfall, collaterals, borrows). A non-zero equity value indicates the account has available borrowable value, a non-zero shortfall value indicates the account is currently below the collateral requirement and is subject to liquidation. At most one of equity or shortfall shall be non-zero. Collaterals and borrows represent the current collateral and borrow value is USD with 36 integer precision which for example, 360000000000000000000000000000000000000000 indicates 360000 in USD.
function calcAccountEquity(address _account)
public
view
override
returns (
uint256 equity,
uint256 shortfall,
uint256 collaterals,
uint256 borrows
)

liquidateCalculateSeizeTokens()

Compute the amount of collateral iToken available to seize after repaying a specific amount of borrow asset.
function liquidateCalculateSeizeTokens(
address _iTokenBorrowed,
address _iTokenCollateral,
uint256 _actualRepayAmount
)
external
view
override
returns (uint256 _seizedTokenCollateral)
