StrategyManager
This contract handles the addition and the update of execution strategies.
Methods​
addStrategy​
function addStrategy(uint16 standardProtocolFeeBp, uint16 minTotalFeeBp, uint16 maxProtocolFeeBp, bytes4 selector, bool isMakerBid, address implementation) external nonpayable
This function allows the owner to add a new execution strategy to the protocol.
Strategies have an id that is incremental. Only callable by owner.
Parameters​
| Name | Type | Description |
|---|---|---|
| standardProtocolFeeBp | uint16 | Standard protocol fee (in basis point) |
| minTotalFeeBp | uint16 | Minimum total fee (in basis point) |
| maxProtocolFeeBp | uint16 | Maximum protocol fee (in basis point) |
| selector | bytes4 | Function selector for the strategy |
| isMakerBid | bool | Whether the function selector is for maker bid |
| implementation | address | Implementation address |
cancelOwnershipTransfer​
function cancelOwnershipTransfer() external nonpayable
This function is used to cancel the ownership transfer.
This function can be used for both cancelling a transfer to a new owner and cancelling the renouncement of the ownership.
confirmOwnershipRenouncement​
function confirmOwnershipRenouncement() external nonpayable
