# 從 Sim 遷移至 Alchemy 的 Data APIs

[Dune 將於 2026 年 8 月 1 日終止 Sim API](https://dune.com/blog/sunsetting-sim)。如果你的應用程式使用 Sim 來取得錢包餘額、交易紀錄、代幣資料或 DeFi 部位，你需要在期限前找到替代方案。

大多數餘額、NFT、代幣與活動相關的工作流程，都能對應到[Alchemy 的 Data APIs](https://www.alchemy.com/docs/data)。少數項目沒有直接對應的產品化端點，這些會在下方標註出來，方便你在搬移正式環境流量前先評估範圍。

## Alchemy 涵蓋的範圍

下方表格將最常用的 Sim 端點對應到最接近的 Alchemy 端點。標註「No equivalent」的列沒有直接對應的產品化端點，這類工作流程請在切換正式環境流量前先與 Alchemy 團隊溝通。

### 代幣與餘額

## 四步驟完成搬遷

### 1. 取得你的 Alchemy API key

[在 Alchemy Dashboard 建立應用程式](https://dashboard.alchemy.com/)並複製你的 API key。每個端點的確切請求 URL 不盡相同，請依照各對應列的文件連結，取得目前的路徑與請求格式。

### 2. 更新驗證方式與請求格式

Sim 使用 `X-Sim-Api-Key` 標頭，並在其中內嵌 chain ID。Alchemy 則以 API key 進行驗證，且請求與回應格式依產品而異。

搬遷前，Sim 的請求大致如下：

<CodeSnippet
  language="bash"
  code={`curl https://api.sim.dune.com/v1/evm/balances/0xYOUR_ADDRESS \\
  -H "X-Sim-Api-Key: YOUR_SIM_KEY"`}
/>

搬遷時，請依各 Alchemy 端點的文件取得該產品確切的請求主體、驗證方式與回應欄位。

### 3. 更新 chain 識別碼

Sim 使用數字形式的 chain ID。Alchemy 使用字串形式的 network slug，若同一請求要查詢多條鏈，則以陣列傳入。

<EmbeddedTable
  table={{
    columns: [
      { key: "chain", width: 180, title: "Chain", dataType: "object" },
      {
        key: "simChainId",
        width: 180,
        title: "Sim chain ID",
        dataType: "object",
      },
      {
        key: "alchemyNetwork",
        width: 220,
        title: "Alchemy network",
        dataType: "object",
      },
    ],
    data: [
      {
        id: 0,
        chain: { title: "<p>Ethereum</p>", tooltip: "", icon: "" },
        simChainId: { title: "<p>1</p>", tooltip: "", icon: "" },
        alchemyNetwork: {
          title: "<p><code>eth-mainnet</code></p>",
          tooltip: "",
          icon: "",
        },
      },
      {
        id: 1,
        chain: { title: "<p>Base</p>", tooltip: "", icon: "" },
        simChainId: { title: "<p>8453</p>", tooltip: "", icon: "" },
        alchemyNetwork: {
          title: "<p><code>base-mainnet</code></p>",
          tooltip: "",
          icon: "",
        },
      },
      {
        id: 2,
        chain: { title: "<p>Arbitrum</p>", tooltip: "", icon: "" },
        simChainId: { title: "<p>42161</p>", tooltip: "", icon: "" },
        alchemyNetwork: {
          title: "<p><code>arb-mainnet</code></p>",
          tooltip: "",
          icon: "",
        },
      },
      {
        id: 3,
        chain: { title: "<p>Polygon</p>", tooltip: "", icon: "" },
        simChainId: { title: "<p>137</p>", tooltip: "", icon: "" },
        alchemyNetwork: {
          title: "<p><code>polygon-mainnet</code></p>",
          tooltip: "",
          icon: "",
        },
      },
      {
        id: 4,
        chain: { title: "<p>Solana</p>", tooltip: "", icon: "" },
        simChainId: {
          title: "<p><code>solana</code></p>",
          tooltip: "",
          icon: "",
        },
        alchemyNetwork: {
          title: "<p><code>solana-mainnet</code></p>",
          tooltip: "",
          icon: "",
        },
      },
    ],
  }}
/>

每個產品支援的鏈不盡相同。搬遷各端點前，請先查看 [Alchemy 鏈支援頁面](https://dashboard.alchemy.com/chains)。

### 4. 更新分頁方式

Sim 使用 offset 式分頁。Alchemy 使用 cursor 式分頁：你需要將前一次回應中的 token 傳回。確切的參數名稱依端點而異，請查閱你要搬遷的產品文件。

<CodeSnippet
  language="bash"
  code={`# Sim
?limit=100&offset=YOUR_NEXT_OFFSET`}
/>

## 為什麼選擇 Alchemy

從 Sim 搬遷，也能讓你把更多技術堆疊整合到單一平台上。

- **單一平台：** Data APIs、Node APIs、Wallet APIs 與 Transaction Simulation 都在同一把 key 底下，讓你在擴充資料功能之外，不必再拼湊更多供應商。
- **Solana 支援：** 原生 Solana RPC、支援 SPL 餘額的 Portfolio，以及支援更豐富 Solana 查詢的 DAS API。
- **交易模擬：** 在交易上鏈前預測資產變化、解碼 trace，並模擬 bundle。
- **企業級支援：** 企業團隊在關鍵搬遷期間可獲得專屬支援與正式環境穩定性保障。
- **針對 Sim 客戶的特別定價：** 在 Sim 逐步退場期間，從 Sim 搬遷的團隊可享 Alchemy 優惠定價。[聯繫我們](https://www.alchemy.com/contact-sales)並告知你的 Sim 帳號。

## 開始使用

Sim 將於 2026 年 8 月 1 日關閉。請現在就開始，讓你有足夠時間在期限前並行運作兩套整合，並驗證回應是否一致。
