How to Add Avalanche Network to MetaMask

·

MetaMask is a popular cryptocurrency wallet available as a browser extension for Chrome and Firefox, as well as a mobile app for iOS and Android. It offers a user-friendly interface for storing digital assets and executing transactions across multiple blockchain networks.

Beyond Ethereum, MetaMask supports various blockchain ecosystems, including Binance Smart Chain, Polygon, and Avalanche. This guide provides a step-by-step walkthrough for connecting your MetaMask wallet to the Avalanche network.

Prerequisites for Using Avalanche on MetaMask

To interact with Avalanche decentralized applications (DApps), you need a compatible Web3 wallet like MetaMask. However, before using Avalanche tokens (AVAX) within MetaMask, you must manually add the Avalanche network to your wallet.

It is essential to note that MetaMask only supports the Avalanche Contract Chain (C-Chain). Always ensure that your AVAX tokens are on the C-Chain before attempting to transfer them to MetaMask. Using an incorrect chain may result in permanent loss of funds.

Creating a MetaMask Wallet

If you already have a MetaMask wallet set up, proceed to the next section. If not, follow these steps to create one:

  1. Visit the official MetaMask website to download and install the browser extension or mobile app. Always verify that you are using the legitimate source to avoid phishing attempts.
  2. Open MetaMask and click "Get Started."
  3. Select "Create a Wallet" to generate a new wallet. Alternatively, choose "Import Wallet" if you already have a seed phrase.
  4. You may be asked to share anonymous usage data to help improve MetaMask. Your choice here does not affect functionality.
  5. Create a strong and unique password for your wallet.
  6. Back up your seed phrase. This is crucial for recovering your wallet if you lose access. Watch the provided educational video to understand best practices.
  7. Write down the seed phrase in the correct order and store it securely offline. Never share it with anyone.
  8. Confirm your backup by correctly re-entering the seed phrase when prompted.
  9. Your wallet is now ready. Click "All Done" to access it.
  10. For easier access, pin the MetaMask extension to your browser’s toolbar.

Adding Avalanche Network to MetaMask

By default, MetaMask is connected to the Ethereum Mainnet. To add the Avalanche network:

  1. Open your MetaMask extension and click the network selection dropdown at the top.
  2. Select "Add Network."

  3. You will be redirected to a settings page. Enter the following network details manually:

    • Network Name: Avalanche Network
    • New RPC URL: https://api.avax.network/ext/bc/C/rpc
    • Chain ID: 43114 or 0xa86a
    • Currency Symbol: AVAX
    • Block Explorer URL: https://snowtrace.io/
  4. Click "Save." Your MetaMask wallet is now connected to the Avalanche C-Chain.

Transferring AVAX to Your MetaMask Wallet

Once the network is added, you can transfer AVAX tokens into your MetaMask wallet. You can do this from another Avalanche wallet or a supported exchange.

Method 1: From an Avalanche Wallet

The Avalanche network consists of three chains: Exchange Chain (X-Chain), Contract Chain (C-Chain), and Platform Chain (P-Chain). MetaMask only interacts with the C-Chain.

  1. Log in to your Avalanche Wallet.
  2. Check your Balance tab to see which chain your AVAX is on.

  3. If your funds are on the X-Chain, you must first cross-chain transfer them to the C-Chain:

    • Click Cross Chain in the left menu.
    • Select C Chain as the destination.
    • Enter the amount and click Confirm. A small transaction fee will apply.
  4. To send AVAX to MetaMask, go to the Send tab.
  5. Ensure C Chain is selected as the source chain.
  6. Enter the amount you wish to send.
  7. Open MetaMask, copy your wallet address.
  8. Paste your MetaMask address into the To Address field in the Avalanche wallet.
  9. Review the gas fee and click Confirm. Once the transaction is confirmed, the AVAX will appear in your MetaMask wallet.

Method 2: From a Centralized Exchange (e.g., Binance)

You can also withdraw AVAX directly from a supported exchange to your MetaMask wallet.

  1. Log in to your exchange account and navigate to the Wallet Overview or Spot Wallet.
  2. Click Withdraw and select AVAX.
  3. Copy your MetaMask wallet address from the extension.
  4. On the exchange, paste your address into the withdrawal field.
  5. Critically Important: Select the Avalanche C-Chain network for withdrawal. Selecting an incorrect network (like Ethereum ERC-20) will result in lost funds.
  6. Enter the amount and click Withdraw.
  7. Review all transaction details carefully and acknowledge any risk warnings.
  8. Complete any two-factor authentication (2FA) steps required by the exchange.
  9. Submit the withdrawal. The funds will be sent to your MetaMask address after processing.

Frequently Asked Questions

Why can’t I see my AVAX tokens in MetaMask after sending them?
First, ensure you have successfully added the Avalanche network to MetaMask and not just the token. Then, confirm the transaction was sent to the C-Chain and that the receiving address is correct. Transactions can take a few moments to confirm on the blockchain.

What is the difference between Avalanche’s X-Chain and C-Chain?
The X-Chain is used for trading and creating assets, while the C-Chain is for smart contracts and is Ethereum Virtual Machine (EVM) compatible. This EVM compatibility is what allows MetaMask to interact with it.

Can I use the same seed phrase for my Avalanche and Ethereum wallets?
Yes. Your seed phrase恢复s your private keys for all assets and networks accessed through your MetaMask wallet. The same seed phrase works across all EVM-compatible chains added to MetaMask.

Is there a risk of losing funds when adding a custom network?
The risk is low if you enter the correct RPC details from a trusted source. However, entering incorrect information could lead to failed transactions or make you vulnerable to phishing. Always double-check network parameters.

What can I do once Avalanche is added to MetaMask?
You can interact with all Avalanche-based decentralized applications (DApps), including decentralized exchanges (DEXs) like Trader Joe and Pangolin, lending protocols, NFT marketplaces, and more.

Do I need to pay gas fees on Avalanche?
Yes, transactions on the Avalanche C-Chain require gas fees paid in AVAX. However, fees are typically much lower than on the Ethereum network.
