State Variables

flashFee

Retrieves the global flash fee, denoted as a fixed-point number where 1e18 is 100%.

Notes:

• This fee represents a percentage, not an amount. Do not confuse it with {IERC3156FlashLender.flashFee}, which calculates the fee amount for a specified flash loan amount.
• Unlike the protocol fee, this is a global fee applied to all flash loans, not a per-asset fee.

UD60x18 public override flashFee;

isFlashAsset

Retrieves a flag indicating whether the provided ERC-20 asset can be flash loaned.

mapping(IERC20 asset => bool supported) public override isFlashAsset;

protocolFees

Retrieves the protocol fee for all streams created with the provided ERC-20 asset.

mapping(IERC20 asset => UD60x18 fee) public override protocolFees;

Functions

constructor

Emits a {TransferAdmin} event.

constructor(address initialAdmin);

Parameters

initialAdmin	address	The address of the initial contract admin.

setFlashFee

Updates the flash fee charged on all flash loans made with any ERC-20 asset.

function setFlashFee(UD60x18 newFlashFee) external override onlyAdmin;

Parameters

Name	Type	Description
newFlashFee	UD60x18	The new flash fee to set, denoted as a fixed-point number where 1e18 is 100%.

setProtocolFee

Sets a new protocol fee that will be charged on all streams created with the provided ERC-20 asset.

Emits a {SetProtocolFee} event. Notes:

• The fee is not denoted in units of the asset's decimals; it is a fixed-point number. Refer to the PRBMath documentation for more detail on the logic of UD60x18.
• Does not revert if the fee is the same. Requirements:
• msg.sender must be the contract admin.

function setProtocolFee(IERC20 asset, UD60x18 newProtocolFee) external override onlyAdmin;

Parameters

Name	Type	Description
asset	IERC20	The contract address of the ERC-20 asset to update the fee for.
