Cách thêm RPC mạng tùy chỉnh

Có cần dịch bài viết này không?

MetaMask can access many more networks than just Ethereum mainnet: you can add any EVM-compatible network directly within your wallet and browse Snaps for additional non-EVM interoperability.

Ba chữ đầu RPC là viết tắt của gọi hàm từ xa, là một bộ giao thức cho phép một ứng dụng khách (như MetaMask) tương tác với một chuỗi khối. You can add multiple RPC URLs for a single network and edit the default RPC URL from your list of networks in both Extension and Mobile settings.

ghi chú

Adding a custom RPC URL will disable Smart Transaction capabilities. To re-enable this, you'll need to switch back to the default RPC URL from the network dropdown selector.

On both Mobile and Extension, you can easily add several prominent networks with just a click. Những mạng đó bao gồm:

  • Arbitrum
  • Avalanche
  • BNB Chain/BSC
  • Base
  • Optimism
  • Polygon
  • zkSync Era

You can find this using the following steps:

From the homepage of your wallet, click on the network selector in the top left. Scroll down until you see the 'Additional networks' section. Alternatively, you can also search for the network to add in the search bar.

Tap the "Add" button next to the network to add it to your MetaMask instance.

Network switching

MetaMask is in the process of improving the networking switching experience. As of v12.0, you will no longer have to manually switch between networks while connected to multiple dapps at the same time. This feature is currently available in Extension only.

Thêm một mạng bằng cách thủ công

If you don’t see a desired network in the list, you can follow these instructions to establish the network connection manually:

  1. Click on the network selector button. This will display a list of networks that you've added already.

  2. Click "Add custom network":

  3. A screen will appear where you can enter the details of the network you wish to add. Click "Save" to add the network.

The details for the above fields can be found in our network profiles or docs (i.e. developer documentation) or how-to guides for each network. Ví dụ:

Adding or editing RPC URLs

You can add multiple RPC URLs for a single network and edit the default RPC URL from your list of networks in both Extension and Mobile settings.

  1. Click the network icon in the top left of your wallet to show the list of enabled networks.
  2. Locate the desired network you want to edit and click the 3 dots to edit.

  1. Select the Default RPC URL dropdown field and click “Add RPC URL”.
  2. Enter the URL, nickname, and save your configurations.

MetaMask add RPC URL

You can now toggle between various RPC URLs directly from the network drop-down selector when you want to switch providers. To delete any RPC URL, follow the same steps above and click on the trash bin icon to delete.

Also, please note that adding a network on one device does not mean it will appear on another device when accessing the same account. If you add it on Extension, it will not automatically be added to your MetaMask Mobile app yet, and vice versa.

Custom networks will also need to re-added if you uninstall the browser extension or mobile app (after which you'd need to restore your wallet using your Secret Recovery Phrase).
