ORCA事件的实时跟踪

在本文中，我们将探讨使用 Shyft Callback API 实时监听 Orca 上的事件的过程。

ORCA事件的实时跟踪

在今天的文章中，我们将探索跟踪 Orca 事件的最简单方法之一，包括使用 Shyft Callback API 创建池、交换代币、添加流动性和删除流动性。

Orca 是在 Solana 区块链上交换加密货币的最简单方法。 在这里，你可以以最低的交易费用和比以太坊上任何 DEX 更低的延迟来交换代币，同时知道你得到的是公平的价格。 此外，你可以向交易池提供流动性，以赚取一部分交易费用。

请在此处阅读 SHYFT API 文档。

1、开始之前的准备工作

首先，我们需要一些东西。

注册你的 Shyft 帐户并获取你自己的 Shyft API 密钥。

x-api-key 是一个身份验证参数，可让你访问 Shyft API。 你可以从 Shyft 网站获取自己的 API 密钥。 只需在此处使用你的电子邮件 ID 注册即可免费获取。 如果已有 Shyft API 密钥，请跳过此步骤。

我们的教程将分为三个步骤：

  • 注册 Orca 程序地址的回调。 在此过程中，我们将利用 Shyft JS SDK 注册 Orca 程序地址的回调。
  • 建立一个 API 来监听来自 Shyft 的回调。 该 API 将负责接收来自 Shyft 的回调数据。
  • 回调数据分析：收到Shyft的回调数据后，我们将分析该数据的结构。 相信我，回调数据结构非常容易阅读和理解。

2、注册回调API

Shyft 允许我们为特定地址设置回调。 这意味着每当这些地址发生任何链上事件时，Shyft 都会及时通知我们相关事件数据。 在我们的场景中，我们为 Orca 程序地址设置了回调。 这使得 Shyft 能够在发生池创建、互换、增加流动性或消除流动性等事件时及时通知我们。

你可以选择通过手动调用 Shyft 的回调注册 API 或使用 Shyft JS SDK 并提供必要的数据来注册回调。 在我们的教程中，我们将选择 Shyft JS SDK 以增加便利。 有关回调 API 的更多详细信息，可以参考此链接。

// setup Shyft client
import { Network, ShyftSdk } from "@shyft-to/js"

const ORCA_SHIRLPOOLS_ADDRESS = "whirLbMiicVdio4qvUfM5KAg6Ct8VwpYzGff3uctyCc";

const registerCallback = async () => {
  const shyft = new ShyftSdk({
    apiKey: process.env.NEXT_PUBLIC_SHYFT_API_KEY!,
    network: Network.Mainnet,
  });

  await shyft.callback.register({
    network: Network.Mainnet,
    addresses: [ORCA_SHIRLPOOLS_ADDRESS],
    // The URL of your API that listens for the callback event.
    // We will be set up in the next step.
    callbackUrl: `${window.location.href}api/callback`,
    // In our tutorial, we are only interested in four events, but you can provide as many events as you like.
    events: [TxnAction.CREATE_POOL, TxnAction.SWAP, TxnAction.ADD_LIQUIDITY, TxnAction.REMOVE_LIQUIDITY],
  });

  console.log("success");
};

3、设置API接收回调

该 API 是标准的 POST API。 我们在上一步中向 Shyft 提供了该 API 的 URL。 当事件发生时，Shyft 会调用该 API 并将数据发送给我们。 我们的责任包括检查和分析数据。 在我们的文章中，我们仅呈现数据，但你可以随意将其用于任何您想要的用途，例如在前端显示此数据或将其存储在数据库中以供以后使用。 要进一步了解回调数据的结构，可以参考此链接。

import { CallbackDataType } from "@/types";
import { NextApiResponse } from "next";
import { NextRequest } from "next/server";
import { TxnAction } from "@shyft-to/js";

const ACTIONS = [
  TxnAction.CREATE_POOL,
  TxnAction.ADD_LIQUIDITY,
  TxnAction.REMOVE_LIQUIDITY,
  TxnAction.SWAP,
];

export async function POST(req: NextRequest, res: NextApiResponse) {
  const body = (await req.json()) as CallbackDataType;
  if (
    !body.type ||
    !body.actions ||
    body.status !== "Success" ||
    !ACTIONS.includes(body.type as TxnAction)
  )
    return res.status(400).json({ message: "Invalid callback data" });

  // You can store the callback data into database for later use.
  console.dir(body, { depth: null });

  return Response.json({ success: true });
}

4、回调数据分析

我们的后端服务器现已全面运行，每当发生重大链上事件（包括 Orca 上的代币交换、流动性增加或删除）时，都可以无缝接收来自 Shyft 的实时数据。 此数据流对于你的去中心化应用程序 (dApp) 具有巨大的价值，使你能够在前端编排动态、实时更新，从而确保你的用户保持知情和参与。

现在，让我们来看看我们收到的一些事件。

我们收到每笔链上交易的人类可读数据。

  • timestamp：时间戳，交易发生的日期和时间。
  • type：类型字段指示交易的操作，在本例中为“交换”。
  • Fee、fee_payer 和 Signers 字段是不言自明的：它们代表交易的 Gas 费、支付费用的钱包以及为交易签名的钱包。
  • protocol字段包含执行事务的程序的名称和地址。
  • status：状态，交易的结果。
  • actions 字段是提供详细信息的操作列表。 在这种情况下，可以观察交换器（即钱包）执行此交换。 此外，还可以查看换入和换出的代币的详细信息，包括代币地址、名称、符号、图像 URL 和数量。

上面我们已经解释了一些字段，所以我们只需要明确 actions 字段即可。 在这种情况下，操作字段包括有关流动性提供者地址和池地址的信息。 此外，我们可以观察添加到池中的代币对。

与添加流动性事件类似，此 JSON 包含操作字段，其中包括有关流动性提供者地址和池地址的信息。 此外，我们可以观察从池中删除的代币对。

5、结束语
