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
一键发币： SOL | BNB | ETH | BASE | Blast | ARB | OP | POLYGON | AVAX | FTM | OK

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
