How to add Optimism to MetaMask?

如何向 MetaMask 添加 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.

作为一款软件钱包（也称为热钱包），MetaMask 使用户能够将数字资产存储在与 EVM 兼容的区块链上，包括 Optimism。 MetaMask 作为流行网络浏览器的扩展提供了一种非常方便的在 Optimism 区块链上进行交易的方式，其原生代币是 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 并不是链上交易最安全的方法。为了获得最佳安全性，强烈建议用户将 MetaMask 与 Ledger 等硬件钱包（通常称为“冷钱包”）配对。与本质上连接互联网的 MetaMask 不同，Ledger 设备离线存储加密货币，为您的数字资产提供额外的安全层。

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 可以通过应用程序直接链接到 MetaMask，从而使用户能够从两种钱包类型中受益。这种组合提供了热钱包的便利性和冷钱包的增强安全性。

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 制造的硬件钱包被广泛认为是存储比特币和其他加密资产的最安全、最可靠的方式。只要小心处理助记词存储，任何恶意行为者或软件就不可能危及您的加密货币的安全。

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

以下是向您的 MetaMask 钱包添加 Optimism 所需采取的步骤的快速细分：

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

1. 转到 MetaMask 钱包的“设置”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”.

打开您的 MetaMask 钱包，然后单击右上角的个人资料图标。从出现的下拉菜单中选择“设置”。

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

进入“设置”菜单后，选择“网络”。

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.

在这里，您将能够看到您的 MetaMask 当前配置的网络列表。单击“添加网络”将 Optimism 添加到您的 MetaMask 钱包。

2. Choose the Optimism (OP Mainnet) network

2.选择Optimism（OP主网）网络

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.”

正如您将看到的，Optimism 已被列为 MetaMask 用户的热门网络，这使得将其添加到 MetaMask 的过程更加简单。只需单击“OP Mainnet”旁边的“添加”，然后单击“批准”。

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

MetaMask 会提示您是否要将 OP 主网添加到支持的网络列表中。单击“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.

接下来，您应该看到出现以下消息，通知您 OP 主网与您的 MetaMask 钱包已成功集成。您可以点击“切换到OP主网”按钮立即切换到Optismim网络。

3. (Optional) Add the Optimism network manually

3.（可选）手动添加 Optimism 网络

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).

如果您在列表中没有看到 Optismim 网络，或者只是想手动添加它，请不要担心。您可以通过单击“手动添加网络”按钮轻松完成此操作（检查第 2 步中第一张图片的底部）。

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

要手动添加 Optimism 网络，请将以下信息复制到字段中：

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

接下来，单击“保存”。如果您提供的信息正确，MetaMask 将通知您已成功将 Optimism 添加到可用网络中。

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.

如果您再次打开 MetaMask 钱包，您会发现您已自动切换为使用 Optimism。与以太坊主网一样，Optimism 的默认货币是 ETH。如果您想切换回以太坊或任何其他网络，您可以使用 MetaMask 界面右上角的下拉列表轻松完成此操作。

How to add Optimism-based tokens to MetaMask

如何将基于 Optimism 的代币添加到 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. 

切换到 Optimism 网络后，您无需手动将 ETH 添加到 MetaMask。但是，您需要手动添加您想要使用的任何其他基于乐观的令牌。

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

1. 使用区块浏览器查找代币的合约地址

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.

在我们的示例中，我们将把 OP 代币添加到 MetaMask 钱包的 Optimism 网络中。您需要代币的合约地址，您可以在任何 Optimism 区块浏览器上找到该地址。我们将使用 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.

我们将在平台上搜索“OP”并转到第一个结果。在“概述”下，您将能够看到合约地址。
