Constants

PERMIT2

contract IAllowanceTransfer PERMIT2

permit2 contract, deployed to same address on EVM networks, see https://github.com/Uniswap/permit2

EXCHANGE_PRICES_PRECISION

uint256 EXCHANGE_PRICES_PRECISION

precision for exchange prices

SECONDS_PER_YEAR

uint256 SECONDS_PER_YEAR

Ignoring leap years

MAX_REWARDS_RATE

uint256 MAX_REWARDS_RATE

max allowed reward rate is 50%

LIQUIDITY

contract IFluidLiquidity LIQUIDITY

address of the Liquidity contract.

LENDING_FACTORY

contract IFluidLendingFactory LENDING_FACTORY

address of the Lending factory contract.

ASSET

contract IERC20 ASSET

address of the underlying asset contract.

DECIMALS

uint8 DECIMALS

number of decimals for the fToken, same as ASSET

LIQUIDITY_EXCHANGE_PRICES_SLOT

bytes32 LIQUIDITY_EXCHANGE_PRICES_SLOT

slot ids in Liquidity contract for underlying token. Helps in low gas fetch from liquidity contract by skipping delegate call with readFromStorage

LIQUIDITY_TOTAL_AMOUNTS_SLOT

bytes32 LIQUIDITY_TOTAL_AMOUNTS_SLOT

LIQUIDITY_USER_SUPPLY_SLOT

bytes32 LIQUIDITY_USER_SUPPLY_SLOT

constructor

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

Parameters

_getLiquiditySlotLinksAsset

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

contract IFluidLendingRewardsRateModel _rewardsRateModel

address of the LendingRewardsRateModel.

_liquidityExchangePrice

uint64 _liquidityExchangePrice

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

_tokenExchangePrice

uint64 _tokenExchangePrice

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

_lastUpdateTimestamp

uint40 _lastUpdateTimestamp

timestamp when exchange prices were updated the last time

_status

uint8 _status

status for reentrancy guard

_rewardsActive

bool _rewardsActive

flag to signal if rewards are active without having to read slot 6

_rebalancer

address _rebalancer

rebalancer address allowed to call rebalance() and source for funding rewards (ReserveContract).

constructor

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

Parameters

_checkValidAddress

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

modifier validAddress(address value_)

validates that an address is not the zero address
