This guide provides a detailed overview to help users add OP Mainnet to MetaMask. To begin, users must ensure they have access to the MetaMask application, which can be downloaded as an extension for all major web browsers, including Chrome, Edge, Firefox, and Opera.

本指南提供了詳細的概述，以協助使用者將 OP 主網新增至 MetaMask。首先，用戶必須確保他們能夠訪問 MetaMask 應用程序，該應用程式可以作為所有主要網路瀏覽器的擴充功能下載，包括 Chrome、Edge、Firefox 和 Opera。

In the following sections, we will demonstrate how you can effortlessly add Optimism to MetaMask in just a few simple steps.

在以下部分中，我們將示範如何透過幾個簡單的步驟輕鬆地將 Optimism 新增至 MetaMask。

如何為 MetaMask 新增 Optimism？

As a software wallet (also known as a hot wallet), MetaMask enables users to store digital assets on EVM-compatible blockchains, including Optimism. Being available as an extension for popular web browsers, MetaMask provides a highly convenient way to transact on the Optimism blockchain, whose native token is OP.

作為一款軟體錢包（也稱為熱錢包），MetaMask 使用戶能夠將數位資產儲存在與 EVM 相容的區塊鏈上，包括 Optimism。 MetaMask 作為流行網頁瀏覽器的擴展提供了一種非常方便的在 Optimism 區塊鏈上進行交易的方式，其原生代幣是 OP。

However, it's important to note that MetaMask is not the most secure method for on-chain transactions. For optimal security, users are strongly advised to pair MetaMask with a hardware wallet (commonly referred to as a "cold wallet") such as Ledger. Unlike MetaMask, which is inherently internet-connected, Ledger devices store cryptocurrency offline, offering an additional layer of security for your digital assets.

然而，值得注意的是，MetaMask 並不是鏈上交易最安全的方法。為了獲得最佳安全性，強烈建議用戶將 MetaMask 與 Ledger 等硬體錢包（通常稱為「冷錢包」）配對。與本質上連接互聯網的 MetaMask 不同，Ledger 裝置離線儲存加密貨幣，為您的數位資產提供額外的安全層。

Ledger can be directly linked to MetaMask through the application, allowing users to benefit from both wallet types. This combination offers the ease of a hot wallet and the enhanced security of a cold wallet.

Ledger 可以透過應用程式直接連結到 MetaMask，從而使用戶能夠從兩種錢包類型中受益。這種組合提供了熱錢包的便利性和冷錢包的增強安全性。

Hardware wallets manufactured by Ledger are widely regarded as the safest and most reliable way to store Bitcoin and other crypto assets. As long as the seed phrase storage is handled with care, there's no way that any malicious actor or software could endanger the safety of your crypto.

Ledger 製造的硬體錢包被廣泛認為是儲存比特幣和其他加密資產的最安全、最可靠的方式。只要小心處理助記詞存儲，任何惡意行為者或軟體就不可能危及您的加密貨幣的安全。

Here’s a quick breakdown of the steps you’ll need to take to add Optimism to your MetaMask wallet:

以下是為您的 MetaMask 錢包添加 Optimism 所需採取的步驟的快速細分：

1. Go to the “Settings” section of your MetaMask wallet

1. 前往 MetaMask 錢包的「設定」部分

Open your MetaMask wallet, then click the profile icon in the top right corner. From the drop-down menu that appears, select “Settings”.

打開您的 MetaMask 錢包，然後點擊右上角的個人資料圖示。從出現的下拉式選單中選擇“設定”。

Once you’re in the “Settings” menu, select “Networks.”

進入“設定”選單後，選擇“網路”。

Here, you will be able to see the list of networks that your MetaMask is currently configured to work with. Click “Add network” to add Optimism to your MetaMask wallet.

在這裡，您將能夠看到您的 MetaMask 目前配置的網路清單。點擊「新增網路」將 Optimism 新增到您的 MetaMask 錢包。

2. Choose the Optimism (OP Mainnet) network

2.選擇Optimism（OP主網）網絡

As you will be able to see, Optimism is already listed as a popular network for MetaMask users, which makes the process of adding it to your MetaMask even simpler. Simply click “Add” next to “OP Mainnet” and then click “Approve.”

正如您將看到的，Optimism 已被列為 MetaMask 用戶的熱門網絡，這使得將其添加到 MetaMask 的過程更加簡單。只需點擊“OP Mainnet”旁邊的“新增”，然後點擊“批准”。

MetaMask will prompt you whether you want to add the OP Mainnet to the list of supported networks. Click “Approve”.

MetaMask 會提示您是否要將 OP 主網新增至支援的網路清單。按一下“批准”。

Next, you should see the following message appear, notifying you about the successful integration of the OP Mainnet with your MetaMask wallet. You can click the “Switch to OP Mainnet” button to switch to the Optismim network immediately.

接下來，您應該會看到出現以下訊息，通知您 OP 主網與您的 MetaMask 錢包已成功整合。您可以點擊「切換到OP主網」按鈕立即切換到Optismim網路。

3. (Optional) Add the Optimism network manually

3.（可選）手動新增 Optimism 網絡

In case you don’t see the Optismim network on the list, or simply want to add it manually, don’t worry. You can easily do so by clicking on the “Add a network manually” button (check the bottom of the first image in Step 2).

如果您在清單中沒有看到 Optismim 網絡，或者只是想手動新增它，請不要擔心。您可以透過點擊「手動新增網路」按鈕輕鬆完成此操作（檢查第 2 步驟中第一張圖片的底部）。

To add the Optimism network manually, copy the following information into the fields:

若要手動新增 Optimism 網絡，請將以下資訊複製到欄位中：

Next, click “Save.” If you provide the information correctly, MetaMask will inform you that you have successfully added Optimism to your available networks.

接下來，點擊“儲存”。如果您提供的資訊正確，MetaMask 將通知您已成功將 Optimism 新增至可用網路。

If you open your MetaMask wallet again, you will notice that you have automatically switched to using Optimism. The default currency for Optimism, like Ethereum Mainnet, is ETH. If you want to switch back to Ethereum or any other network, you can easily do so using the dropdown list on the top right side of the MetaMask interface.

如果您再次開啟 MetaMask 錢包，您會發現您已自動切換為使用 Optimism。與以太坊主網一樣，Optimism 的預設貨幣是 ETH。如果您想切換回以太坊或任何其他網絡，您可以使用 MetaMask 介面右上角的下拉清單輕鬆完成此操作。

How to add Optimism-based tokens to MetaMask

如何將基於 Optimism 的代幣添加到 MetaMask

You don’t need to manually add ETH to MetaMask after switching to the Optimism network. However, you’ll need to manually add any other Optimism-based tokens that you would like to use. 

切換到 O​​ptimism 網路後，您無需手動將 ETH 新增至 MetaMask。但是，您需要手動添加您想要使用的任何其他基於樂觀的令牌。

1. Find the token’s contract address using a block explorer

1. 使用區塊瀏覽器尋找代幣的合約地址

In our example, we’ll be adding the OP token to the Optimism network in our MetaMask wallet. You’ll need the token’s contract address, which you can find on any Optimism block explorer. We’ll be using OP Mainnet Explorer.

在我們的範例中，我們將把 OP 代幣添加到 MetaMask 錢包的 Optimism 網路中。您需要代幣的合約地址，您可以在任何 Optimism 區塊瀏覽器上找到該地址。我們將使用 OP Mainnet Explorer。

We’ll search for “OP” on the platform and head over to the first result. Under “Overview,” you will be able to see the contract address.

我們將在平台上搜尋“OP”並轉到第一個結果。在「概述」下，您將能夠看到合約地址。
