function (IStore store) public nonpayable Recoverable

Arguments

Name Type Description
store IStore Provide the store contract instance
Source Code 
constructor(IStore store) Recoverable(store) {}

deploy

Deploys a new instance of cxTokens

function deploy(bytes32 coverKey, bytes32 productKey, string tokenName, uint256 expiryDate) external nonpayable nonReentrant 
returns(deployed address)

Arguments

Name Type Description
coverKey bytes32 Enter the cover key related to this cxToken instance
productKey bytes32 Enter the product key related to this cxToken instance
tokenName string
expiryDate uint256 Specify the expiry date of this cxToken instance
Source Code 
function deploy(
    bytes32 coverKey,
    bytes32 productKey,
    string calldata tokenName,
