# Fetch election calls with Solidity

### 🚀  Want a shortcut? 🚀 

[**Start with our boilerplate Solidity smart contract on GitHub**](https://github.com/EveripediaNetwork/everipedia-ap-2020/blob/master/ethereum/contracts/TestnetConsumer.sol). 

### Walkthrough 

1. Begin by starting a [Truffle project ](https://www.trufflesuite.com/)or using [Remix](https://remix.ethereum.org/)
2. Set `pragma` and import the election results contract at the top of your smart contract

```
pragma solidity ^0.6.12;

import "https://raw.githubusercontent.com/EveripediaNetwork/everipedia-ap-2020/master/ethereum/contracts/TestnetConsumer.sol";
```

3\. Paste in this example code and change the `selectWinner` function to do what you need with the data!

```
contract FetchPresidentialWinners {
    struct Winner {
      string winner;
      uint256 resultNow;
      uint256 resultBlock;
    }
    
    ATestnetConsumer internal winners;
    
    constructor() public {
        // the deployed kovan test contract address
        winners = ATestnetConsumer(0x12B7B8Dea45AF31b6303E00C735332A8b6752856);
        
        // the deployed mainnet contract address
        // winners = ATestnetConsumer(0x0792724900B551d200D954a5Ed709d9514d73A9F);
    }
    
    
   function selectWinner(string memory _state) public view returns (string memory winner, uint256 resultNow, uint256 resultBlock)
  {
    (string memory winner, uint256 resultNow, uint256 resultBlock) = winners.presidentialWinners(_state);
    return (winner, resultNow, resultBlock);
  }
}
```

4\. Validate on kovan that you are getting what you expect from the `presidentialWinners` mapping.

If you're using the above solidity code, you can [see here the "already declared states" (all Kovan test data)](https://everipedia-ap-2020.vercel.app/kovan)

5\. Fetch state data for any of all the states you are interested (52 states = 50 + D.C. + US). [See the exact list of states here.](https://github.com/EveripediaNetwork/everipedia-ap-2020/blob/master/src/all-states.js)
