Title: MidnightLib

View helpers that extend the Morpho Midnight contract.

Intended for using MidnightLib for IMidnight.

Functions

computeMaxDebt

Returns the LLTV-weighted collateral value (maxDebt) of borrower, rounded down: the maximum debt the borrower's collateral can support.

Mirrors Morpho Midnight's isHealthy() logic: maxDebt = sum(collateral * price / ORACLE_PRICE_SCALE * lltv / WAD).

function computeMaxDebt(
    IMidnight morphoMidnight,
    bytes32 marketId,
    address borrower,
    CollateralParams[] memory collaterals
) internal view returns (uint256 maxDebt);

Parameters

Name	Type	Description
morphoMidnight	IMidnight
marketId	bytes32
borrower	address
collaterals	CollateralParams[]	The collateral config array from the market.

computeMaxDebtFromAmounts

Returns the LLTV-weighted collateral value (maxDebt) from explicit amounts, rounded down.

Same math as computeMaxDebt but with caller-supplied amounts instead of onchain balances.

function computeMaxDebtFromAmounts(CollateralParams[] memory collaterals, uint256[] memory amounts)
    internal
    view
    returns (uint256 maxDebt);

Parameters

Name	Type	Description
collaterals	CollateralParams[]
amounts	uint256[]	The collateral amounts, indexed by collateral slot (same indexing as collaterals).

computeMaxDebtFromAmounts

Returns maxDebt from explicit amounts, rounded down, lazily fetching and caching oracle prices.

Mutates prices in place: unfetched slots (value 0) are populated on first access.

Callers can pass the same prices array across multiple calls to avoid redundant oracle reads.

Note that 0 is the "not yet fetched" sentinel: if an oracle legitimately returns price 0, it is re-fetched on every call instead of cached.

function computeMaxDebtFromAmounts(
    CollateralParams[] memory collaterals,
    uint256[] memory amounts,
    uint256[] memory prices
) internal view returns (uint256 maxDebt);
