1.打开Remix,创建一个空白模板，命名abc.sol

[https://remix.ethereum.org/](https://remix.ethereum.org/)

2\. 将以下代码粘贴至abc.sol，编译器选择0.8.7，右键点击 complie

    pragma solidity ^0.8.0;
    
    // import "hardhat/console.sol";
    
    contract Comments {
      // Exposed data structure
      struct Comment {
        uint32 id;
        string topic;
        address creator_address;
        string message;
        uint256 created_at;
      }
    
      // Notify users that a comment was added
      event CommentAdded(Comment comment);
    
      uint32 private idCounter;
      mapping(string => Comment[]) private commentsByTopic;
    
      // Fetch a list of comments for a topic
      function getComments(string calldata topic) public view returns(Comment[] memory) {
        return commentsByTopic[topic];
      }
    
      // Persist a new comment
      function addComment(string calldata topic, string calldata message) public {
        Comment memory comment = Comment({
            id: idCounter,
            topic: topic,
            creator_address: msg.sender,
            message: message,
            created_at: block.timestamp
        });
        commentsByTopic[topic].push(comment);
        idCounter++;
        emit CommentAdded(comment);
      }
    
      // Delete comment
      function deleteComment(string calldata id) public {}
    }
    

3.如下图所示进行合约部署，切换到condor链，连接Metamask, 单击deploy. 支付gas后复制生成的合约代码，下一步用到。

3\. 打开[replit](https://replit.com/@phantum/Condor-User-Comment?v=1) , 点击fork

4\. 找到 hooks>useCommentsContract.ts 文件，用刚刚生成的合约，替换第160行的合约，之后运行

5.复制url 去discord提交（提交时候，repl得处于运行状态，等拿到角色后可以关闭网页）
