Solidity Tutorial

🚀  Want a shortcut? 🚀 
​Start with our boilerplate Solidity smart contract on GitHub. 
Walkthrough 
1.Install the contract via npm 
npm install oraqle-contracts
# OR
yarn add oraqle-contracts
2. Set pragma and import the senate contract at the top of your smart contract
pragma solidity 0.6.11;
​
import "oraqle-contracts/contracts/associated-press/Jan2021SenateRunoffs.sol";
3. Paste in this example code and change the parts your need! Don't forget to change the deployed contract address for production.
contract IsPerdueWinner {
    Jan2021SenateRunoffs internal senateRunoffContract;
​
    constructor() public {
        senateRunoffContract = Jan2021SenateRunoffs(
            0x0792724900B551d200D954a5Ed709d9514d73A9F
        );
    }
​
    function isPerdueWinner() public view returns (bool) {
        return
            keccak256(
                bytes(senateRunoffContract.winners("U.S. Senate Class II"))
            ) == keccak256(bytes("Perdue"));
    }
}
4. Validate on kovan that you are getting the following results:
5. Replace the smart contract address on line 6 above with the production contract address and get ready for January 5th!
