Regional availability

While we want to make MetaMask's features accessible to as many people around the world as possible, buying crypto in MetaMask (also referred to as on-ramp) is not available in every country or region.

This is because the companies we partner with cannot operate in every jurisdiction, as their operations are affected by varying laws and regulations.

When you buy crypto in MetaMask, we will automatically show you your options based on what region or country you are in.

I can't buy crypto in my country/region.

If your country/region isn't supported, you may still be able to get tokens into your wallet through other means.

1. One route, for example, could be to buy tokens on a centralized exchange (CEX) and deposit them into MetaMask. See our guide for more information. Also, bear in mind that this route, like on-ramps themselves, will usually require KYC (know your customer) steps, such as proving your identity, and availability may also vary by region. CEXs also differ from MetaMask in that they are custodial — meaning you don't have control of your accounts' private keys.

2. You could also arrange a P2P (peer-to-peer) deposit into your wallet by sending simple transactions.

Regardless of the method you choose, please do your own research before handing over any money, and make sure the platform you're using is safe. Always practise good web3 security habits.

如何购买加密货币

购买加密货币的工作原理

Buying crypto in MetaMask involves using an aggregator of on-ramp providers, making the process accessible, fast, and scalable.

When you enter how much of a token you want to buy, MetaMask's integrations with our vetted providers will spring into life, and fetch you quotes from each. These quotes automatically refresh every 10 seconds to account for gas price fluctuations, minimizing the potential for failed transactions (if gas prices rise after submitting the transaction, your quoted total may be too low to cover transaction costs by the time the transaction is picked up by the network).

Since you input your region and currency during the process, the quotes you're presented with are automatically configured for your circumstances: so no need to worry about whether you'll be able to use the available payment methods in your region, or whether your region is supported by that provider. If it appears on the quote list, you will be able to buy as quoted. Easy.

• Extension and Portfolio
• Mobile

在扩展程序中，点击“买入和卖出”进入 MetaMask Portfolio。

在 MetaMask Portfolio 上，选择所在地区和付款方式后，您将在一个屏幕中完成购买流程，您可以在其中输入金额，调整付款方式（如果您愿意），并选择您的报价。

在移动应用程序上，点击选项卡栏中心的钱包操作按钮。 此操作将打开弹出菜单，您可以在其中选择“买入”按钮。

note

您无法从移动设备访问 MetaMask Portfolio 的买入功能。 因此，请确保您直接转到应用内的买入功能，而不是尝试从 Portfolio.metaask.io买入。

1. 前往您的钱包主页并找到按钮：在扩展程序上，您可以在钱包视图左侧找到“买入/卖出”按钮，该按钮会将您重定向到 MetaMask Portfolio。 如果您已经在 MetaMask Portfolio 上，请选择“转移加密货币”选项卡，然后点击“买入”。

2. 如果您是首次使用，则必须选择您的地区，该地区通常默认为您的当前位置。 如果您以前使用过此功能，MetaMask 将跳过此步骤，并使用上次选择的区域，该区域保存在本地存储中。

从下拉菜单中搜索或滚动，直到找到您的付款方式（卡/银行账户）所注册的国家/地区。 美国用户将能够选择所在州。 如果我们的提供商和付款方式组合至少其中之一目前尚未覆盖您的地区，我们会在此时通知您。 更多有关购买加密货币的其他方式，请参阅此处。

3. 在下一个屏幕，选择付款方式（如果您改变主意，始终可以稍后更改）：

可以选择 Apple Pay/Google Pay（这将根据您的设备来调整）、借记卡/信用卡、PayPal（仅限美国，不包括夏威夷）和银行转账。银行转账机制因您的地区、实名认证（KYC）详情和货币而定，例如英国的快速付款系统 (UK Faster Payments) 、美国的 ACH、巴西的 Pix 和欧洲的 SEPA。 确保您对每个选项旁详细列出的预计持续时间和付款限额感到满意。

4. 使用屏幕顶部的 您想购买 字段选择要购买的代币。

5. 输入所需金额，即您要购买的代币价值（以法币计算）。

6. 选择您的报价。 稍作等待后，您将看到根据您的喜好提供的报价。 报价根据您收到的加密货币数量按降序排列，最高价值选项位于顶部。 从屏幕顶部下拉以强制刷新报价。

您选择供应商时，如果以前从未用过其服务，则可能必须完成实名认证（KYC）。

订单完成后，您将看到以下屏幕：

故障排除

如果我的交易失败了该怎么办？

Since MetaMask does not execute your transaction, the provider will likely be better placed to support than our team. In these situations, we recommend you contact their support teams first.

For any issues you encounter with MetaMask itself (such as problems selecting your region or currency, or with the buying process), get in touch with MetaMask Support via the 'start a Conversation' button on the Support page.

If you're facing problems using a provider's platform, such as payment limits, payment methods, or KYC, we recommend you get in touch with their support teams directly.

为什么我的交易仍然待定？

To get your ordered crypto into your MetaMask wallet, the provider you choose must execute transactions on-chain. This means that, as a minimum, you will need to wait as long as it takes for the transactions to be processed by the network (block time).

Once you submit your request, you can see the pending transaction in your MetaMask activity.

If your bank account was charged and there are delays in receiving your crypto, we recommend you contact the provider's support team directly. Pending purchases (not yet confirmed on the blockchain) are usually caused by the on-ramp provider's pre-authorization processes.
