Manual process
If you can't or don't want to use ChainID, you can add the Filecoin network to your MetaMask manually.
Prerequisites
Before we get started, you’ll need the following:
A Chromium-based browser, or Firefox.
A browser with MetaMask installed.
Steps
The process for configuring MetaMask to use Filecoin is fairly simple but has some very specific variables that you must copy exactly.
Open your browser and open the MetaMask plugin. If you haven’t opened the MetaMask plugin before, you’ll be prompted to create a new wallet. Follow the prompts to create a wallet.
Click the user circle and select Settings.
Select Networks.
Click Add a network.
Scroll down and click Add a network manually.
Enter the following information into the fields:
| Field | Value |

New RPC URL | Either:

Pick one block explorer from the Networks section, and enter the URL into the Block explorer (optional) field.
Review the values in the fields and click Save.
The Filecoin network should now be shown in your MetaMask window.
Done!
You can now use MetaMask to interact with the Filecoin network.
Ledger hardware wallet
MetaMask is compatible with the Ledger hardware wallet. Follow these instructions to connect your Filecoin addresses within MetaMask to your Ledger wallet. This guide assumes you have Ledger Live and MetaMask installed on your computer.
Install the Ledger app
Before you can connect MetaMask to your Ledger, you must install the Filecoin Ledger app on your Ledger device.
Open Ledger Live and navigate to My Ledger.
Connect your Ledger device and unlock it.
Confirm that you allow My Ledger to access your Ledger device. You can do that by clicking both buttons on your Ledger device simultaneously.
Go back to Ledger Live on your computer.
In My Ledger, head over to App catalog and search for Filecoin.
Click Install.
For more details on the official Filecoin Ledger app, check out the Ledger documentation.
Enable expert-mode
MetaMask requires that the Filecoin app on your Ledger device is set to Expert mode.
Open the Filecoin app on your Ledger device.
Use the buttons on your device to navigate to Expert mode.
Press both buttons simultaneously to enable Expert mode.
Connect to MetaMask
Once you have installed the Filecoin app on your Ledger device and enabled expert mode, you can connect your device to MetaMask.
Open your browser and open the MetaMask extension.
In the Accounts menu, select Add hardware wallet.
Select Ledger
A list of accounts should appear. Select an
0x...account.Done!
That's it! You've now successfully connected your Ledger device to MetaMask. When you submit any transactions through MetaMask using this account, the Filecoin Ledger app will prompt you for a confirmation on the Ledger device.
You may see a blind signing warning on your MetaMask device. This is expected, and is the reason why Expert Mode must be enabled before you can interact with the Filecoin Ledger app.
