Functions

constructor

constructor(
    INineLivesFactory _factory,
    ILongtail _longtail,
    address _fusdc,
    IWETH10 _weth,
    ICamelotSwapRouter _camelotSwapRouter
) ;

mint

Mint some shares at the trading id and outcome given, using Longtail to make a swap to fUSDC from the asset given.

function mint(
    address _tradingAddr,
    address _asset,
    bytes8 _outcome,
    uint256 _minShareOut,
    uint256 _maxSharesOut,
    uint256 _amount,
    address _referrer,
    uint256 _rebate,
    uint256 _deadline,
    address _recipient
) external payable returns (uint256);

mintTwice

Mint more than one outcome at once, without any protections for slippage. Best used when the market was created for the first time.

function mintTwice(address _tradingAddr, MintTwice[] memory _outcomes, address _recipient) external;

burn

function burn(
    address _tradingAddr,
    bytes8 _outcome,
    uint256 _minFusdc,
    uint256 _sharesToBurn,
    uint256 _minShareOut,
    uint256 _maxShareBurned,
    address _referrer
) external returns (uint256, uint256);

getShareAddr

function getShareAddr(INineLivesFactory _factory, address _tradingAddr, bytes8 _outcomeId)
    public
    view
    returns (IERC20);

addLiquidity

function addLiquidity(
    address _tradingAddr,
    address _asset,
    uint256 _amount,
    address _recipient,
    uint256 _minLiquidity,
    uint256 _maxLiquidity,
    uint256 _rebate,
    AddLiquidityTokens[] calldata _tokens,
    uint256 _deadline
) external payable returns (AddLiquidityRes memory res);
