Factory
ACO Factory is an implementation of an upgradable proxy that follows the EIP-897. The proxy code is available in
ACOProxy.sol. The implementation of the factory is responsible to create all the ACO tokens. The factory serves as a public registry and is used to look up all ACO tokens added to the system. It is also used to set the ACO tokens' implementation address used to deploy a new one. It also contains logic to turn on the protocol charge. At the moment there are no protocol fees. The proxy for
ACOFactory.sol is deployed at 0x176b98ab38d1aE8fF3F30bF07f9B93E26F559C17 on the Ethereum mainnet. event SetFactoryAdmin(address indexed previousFactoryAdmin, address indexed newFactoryAdmin); Emitted when the factory admin address has been changed.

function factoryAdmin() external view returns(address);Returns the factory admin address.
function acoTokenImplementation() external view returns(address);Returns the ACO token implementation address.
function acoFee() external view returns(uint256);Returns the ACO fee value used on creating new ACO tokens. It is a percentage value (100000 is 100%).
function acoFeeDestination() external view returns(address);Returns the ACO fee destination address used on creating new ACO tokens.
function init(address _factoryAdmin, address _acoTokenImplementation, uint256 _acoFee, address _acoFeeDestination) external;Function to initialize the contract. It should be called through the
data argument when creating the proxy implementation. It must be called only once. The assert is to guarantee that behavior.function setFactoryAdmin(address newFactoryAdmin) external;Function to set the factory admin address. Only can be called by the factory admin.
newFactoryAdminAddress of the new factory admin.
function setAcoTokenImplementation(address newAcoTokenImplementation) external;Function to set the ACO token implementation address. Only can be called by the factory admin.
newAcoTokenImplementationAddress of the new ACO token implementation.
function setAcoFee(uint256 newAcoFee) external;Function to set the ACO fee. Only can be called by the factory admin.
newAcoFeeValue of the new ACO fee. It is a percentage value (100000 is 100%).
function setAcoFeeDestination(address newAcoFeeDestination) external;Function to set the ACO fee destination address. Only can be called by the factory admin.
newAcoFeeDestinationAddress of the new ACO fee destination.
function createAcoToken( address underlying, address strikeAsset, bool isCall, uint256 strikePrice, uint256 expiryTime, uint256 maxExercisedAccounts ) external;Function to create a new ACO token. It deploys a minimal proxy for the ACO token implementation address. Currently, only can be called by the factory admin.
underlyingAddress of the underlying asset (0x0 for Ethereum).strikeAssetAddress of the strike asset (0x0 for Ethereum).isCallWhether the ACO token is the Call type. (False for Put)strikePriceThe strike price with the strike asset precision.expiryTimeThe UNIX time for the ACO token expiration.maxExercisedAccountsThe maximum number of accounts that can be exercised by a transaction.
