solidity
uint256 EXCHANGE_PRICES_PRECISION

precision for exchange prices

SECONDS_PER_YEAR ​

bytes32 LIQUIDITY_TOTAL_AMOUNTS_SLOT

LIQUIDITY_USER_SUPPLY_SLOT ​

solidity
bytes32 LIQUIDITY_USER_SUPPLY_SLOT

constructor ​

solidity
constructor(contract IFluidLiquidity liquidity_, contract IFluidLendingFactory lendingFactory_, contract IERC20 asset_) internal

Parameters ​

NameTypeDescription
liquidity_contract IFluidLiquidityliquidity contract address
lendingFactory_contract IFluidLendingFactorylending factory contract address
asset_contract IERC20underlying token address

_getLiquiditySlotLinksAsset ​

solidity
function _getLiquiditySlotLinksAsset() internal view virtual returns (address)

gets asset address for liquidity slot links, extracted to separate method so it can be overridden if needed

Variables ​

_rewardsRateModel ​

solidity
contract IFluidLendingRewardsRateModel _rewardsRateModel

address of the LendingRewardsRateModel.

_liquidityExchangePrice ​

solidity
uint64 _liquidityExchangePrice

exchange price for the underlying assset in the liquidity protocol (without rewards)

_tokenExchangePrice ​

solidity
uint64 _tokenExchangePrice

exchange price between fToken and the underlying assset (with rewards)

_lastUpdateTimestamp ​

solidity
uint40 _lastUpdateTimestamp

timestamp when exchange prices were updated the last time

_status ​

solidity
uint8 _status

status for reentrancy guard

_rewardsActive ​

solidity
bool _rewardsActive

_rebalancer ​

solidity
address _rebalancer

constructor ​

solidity
constructor(contract IFluidLiquidity liquidity_, contract IFluidLendingFactory lendingFactory_, contract IERC20 asset_) internal

Parameters ​

NameTypeDescription
liquidity_contract IFluidLiquidityliquidity contract address
lendingFactory_contract IFluidLendingFactorylending factory contract address
asset_contract IERC20underlying token address

_checkValidAddress ​

solidity
function _checkValidAddress(address value_) internal pure

checks that address is not the zero address, reverts if so. Calling the method in the modifier reduces bytecode size as modifiers are inlined into bytecode

validAddress ​

solidity
modifier validAddress(address value_)

validates that an address is not the zero address
