Walkthrough

  1. 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!
