IFluidLendingResolver

LENDING_FACTORY

function LENDING_FACTORY() external view returns (contract IFluidLendingFactory)

returns the lending factory address

LIQUIDITY_RESOLVER

function LIQUIDITY_RESOLVER() external view returns (contract IFluidLiquidityResolver)

returns the liquidity resolver address

getAllFTokenTypes

function getAllFTokenTypes() external view returns (string[])

returns all fToken types at the LENDING_FACTORY

getAllFTokens

function getAllFTokens() external view returns (address[])

returns all created fTokens at the LENDING_FACTORY

isLendingFactoryAuth

function isLendingFactoryAuth(address auth_) external view returns (bool)

reads if a certain auth_ address is an allowed auth or not. Owner is auth by default.

isLendingFactoryDeployer

function isLendingFactoryDeployer(address deployer_) external view returns (bool)

reads if a certain deployer_ address is an allowed deployer or not. Owner is deployer by default.

computeFToken

function computeFToken(address asset_, string fTokenType_) external view returns (address)

computes deterministic token address for asset_ for a lending protocol

Parameters

Name	Type	Description
asset_	address	address of the asset
fTokenType_	string	type of fToken: - if underlying asset supports EIP-2612, the fToken should be type EIP2612Deposits - otherwise it should use Permit2Deposits - if it's the native token, it should use NativeUnderlying - could be more types available, check fTokenTypes()

Return Values

Name	Type	Description
[0]	address	token_ detemrinistic address of the computed token

getFTokenDetails

function getFTokenDetails(contract IFToken fToken_) external view returns (struct Structs.FTokenDetails fTokenDetails_)

gets all public details for a certain fToken_, such as fToken type, name, symbol, decimals, underlying asset, total amounts, convertTo values, rewards. Note it also returns whether the fToken supports deposits / mints via EIP-2612, but it is not a 100% guarantee! To make sure, check for the underlying if it supports EIP-2612 manually.

Parameters

Name	Type	Description
fToken_	contract IFToken	the fToken to get the details for

Return Values

Name	Type	Description
fTokenDetails_	struct Structs.FTokenDetails	retrieved FTokenDetails struct
