Inherits: ERC20, ERC20Permit, Error, Constants

Constants ​

TOKEN_NAME_PREFIX ​

prefix for token name. fToken will append the underlying asset name

solidity
string internal constant TOKEN_NAME_PREFIX = "Fluid "

TOKEN_SYMBOL_PREFIX ​

prefix for token symbol. fToken will append the underlying asset symbol

solidity
string internal constant TOKEN_SYMBOL_PREFIX = "f"

State Variables ​

_rewardsRateModel ​

address of the LendingRewardsRateModel.

solidity
IFluidLendingRewardsRateModel internal _rewardsRateModel

__placeholder_gap ​

solidity
uint96 private __placeholder_gap

_liquidityExchangePrice ​

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

solidity
uint64 internal _liquidityExchangePrice

_tokenExchangePrice ​

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

solidity
uint64 internal _tokenExchangePrice

_lastUpdateTimestamp ​

timestamp when exchange prices were updated the last time

solidity
uint40 internal _lastUpdateTimestamp

_status ​

status for reentrancy guard

solidity
uint8 internal _status

_rewardsActive ​

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

solidity
bool internal _rewardsActive

_staticRateModelActive ​

flag to signal if the wired rewards rate model is a static (TVL-independent) rate model

solidity
bool internal _staticRateModelActive

_rebalancer ​

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

solidity
address internal _rebalancer

Functions ​

constructor ​

forwards config to Constants. ERC20 / ERC20Permit metadata is set by the concrete contract constructor so beacon-proxy implementations can use a fixed EIP-712 domain and resolve name/symbol dynamically while the standard fToken keeps deriving them from the underlying asset.

solidity
constructor(IFluidLiquidity liquidity_, IFluidLendingFactory lendingFactory_, IERC20 asset_)
    Constants(liquidity_, lendingFactory_, asset_);

Parameters

NameTypeDescription
liquidity_IFluidLiquidityliquidity contract address
lendingFactory_IFluidLendingFactorylending factory contract address
asset_IERC20underlying token address

_checkValidAddress ​

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

solidity
function _checkValidAddress(address value_) internal pure;

validAddress ​

validates that an address is not the zero address

solidity
modifier validAddress(address value_) ;
