Constants

_DEX_POOL

address _DEX_POOL

_RESERVES_CONVERSION_ORACLE

contract IFluidOracle _RESERVES_CONVERSION_ORACLE

external IFluidOracle used to convert token0 into token1 or the other way around depending on _QUOTE_IN_TOKEN0.

_RESERVES_CONVERSION_INVERT

bool _RESERVES_CONVERSION_INVERT

_QUOTE_IN_TOKEN0

bool _QUOTE_IN_TOKEN0

if true, convert all reserves token1 into token0. otherwise all token0 into token1.

_RESERVES_PEG_BUFFER_PERCENT

uint256 _RESERVES_PEG_BUFFER_PERCENT

if Dex is e.g. USDC / USDT a peg can be assumed instead of fetching the price at the Dex Oracle (which might not even be active in such a case). If so, this var defines the peg buffer to reduce collateral value (and increase debt value) by some defined percentage for safety handling of price ranges. in 1e4: 10000 = 1%, 1000000 = 100%

_DEX_SHARES_DECIMALS

uint8 _DEX_SHARES_DECIMALS

_DEX_TOKENS_DECIMALS_PRECISION

uint8 _DEX_TOKENS_DECIMALS_PRECISION

X128

uint256 X128

_LIQUIDITY

contract IFluidLiquidity _LIQUIDITY

internal immutables read from DEX at time of deployment

_BORROW_TOKEN_0_SLOT

bytes32 _BORROW_TOKEN_0_SLOT

_BORROW_TOKEN_1_SLOT

_EXCHANGE_PRICE_TOKEN_1_SLOT

bytes32 _EXCHANGE_PRICE_TOKEN_1_SLOT

_TOKEN_0_NUMERATOR_PRECISION

uint256 _TOKEN_0_NUMERATOR_PRECISION

_TOKEN_0_DENOMINATOR_PRECISION

uint256 _TOKEN_0_DENOMINATOR_PRECISION

_TOKEN_1_NUMERATOR_PRECISION

uint256 _TOKEN_1_NUMERATOR_PRECISION

_TOKEN_1_DENOMINATOR_PRECISION

uint256 _TOKEN_1_DENOMINATOR_PRECISION

DexViews

_getDexTotalBorrowShares

function _getDexTotalBorrowShares() internal view returns (uint256 totalBorrowShares_)

_getLiquidityDebt

function _getLiquidityDebt(bytes32 borrowTokenSlot_, bytes32 exchangePriceSlot_, bool isToken0_) internal view returns (uint256 debtAmount_)

Retrieves debt amount from liquidity layer for a given token

Parameters

Name	Type	Description
borrowTokenSlot_	bytes32	The storage slot for the borrow token data
exchangePriceSlot_	bytes32	The storage slot for the exchange price of the token
isToken0_	bool	Boolean indicating if the token is token0 (true) or token1 (false)

Return Values

Name	Type	Description
debtAmount_	uint256	The calculated liquidity debt amount adjusted to 1e12 decimals

_getDexDebtReserves

function _getDexDebtReserves() internal view returns (uint256 token0Reserves_, uint256 token1Reserves_)

Get the debt reserves at the Dex adjusted to 1e12 decimals

DexSmartDebtPegOracleImpl

constructor

constructor(address dexPool_, address reservesConversionOracle_, bool quoteInToken0_, bool reservesConversionInvert_, uint256 reservesPegBufferPercent_) internal

Parameters

Name	Type	Description
dexPool_	address	The address of the DEX pool
reservesConversionOracle_	address	The oracle used to convert reserves. Set to address zero if not needed.
quoteInToken0_	bool	The asset to quote in. If true then quote in token0. Can be skipped if no reservesConversionOracle is configured. This should be set to the pegged to asset: E.g. for token0 = WSTETH, token1 = ETH, this should be set to false! if true -> this oracle outputs how much WSTETH one Dex debt share is worth if false -> this oracle outputs how much ETH one Dex debt share is worth
reservesConversionInvert_	bool	Whether to invert the reserves conversion. Can be skipped if no reservesConversionOracle is configured.
reservesPegBufferPercent_	uint256	The percentage buffer for pegged reserves.

_getDexSmartDebtOperate

function _getDexSmartDebtOperate() internal view returns (uint256 rate_)

_getDexSmartDebtLiquidate

function _getDexSmartDebtLiquidate() internal view returns (uint256 rate_)

dexSmartDebtOracleData

Returns the configuration data of the DexSmartDebtOracle.

Return Values

Name	Type	Description
dexPool_	address	The address of the Dex pool.
reservesPegBufferPercent_	uint256	The percentage of the reserves peg buffer.
