Adding the Avalanche C-Chain to MetaMask is a simple yet essential step for anyone looking to explore decentralized applications (dApps), participate in DeFi protocols, or manage AVAX tokens on one of the fastest-growing EVM-compatible blockchains. With its high throughput and low transaction fees, Avalanche has become a top choice for developers and users alike. This guide walks you through the complete process of integrating the Avalanche C-Chain into your MetaMask wallet—securely and efficiently.
Understanding the Avalanche C-Chain
The Avalanche (AVAX) network is uniquely structured into three interoperable blockchains: the X-Chain for asset creation, the P-Chain for staking and subnet coordination, and the C-Chain, which stands for Contract Chain. The C-Chain is where smart contracts are executed and most dApps reside. It’s fully compatible with the Ethereum Virtual Machine (EVM), meaning developers can easily port Ethereum-based applications to Avalanche with minimal changes.
Because of this EVM compatibility, popular wallets like MetaMask can be configured to interact directly with the Avalanche C-Chain. Once set up, you can seamlessly swap tokens, provide liquidity, stake assets, or engage with NFT marketplaces—all within the familiar MetaMask interface.

Prerequisites Before Adding the C-Chain
Before diving into configuration, ensure your environment is ready:
- Install the latest version of the MetaMask browser extension (available for Chrome, Firefox, Brave, and Edge).
- Have an existing wallet account created in MetaMask.
- Maintain stable internet access to validate network connections.
- Hold a small amount of AVAX tokens to cover gas fees when transacting.
⚠️ Security Note: Never share your seed phrase or private keys with anyone. Legitimate services will never ask for them.
Updating MetaMask ensures compatibility with newer networks and enhances security. Always download the extension from official sources to avoid phishing risks.
Avalanche C-Chain Network Parameters
To add any custom network to MetaMask, you need precise technical details. For the Avalanche C-Chain Mainnet, use the following verified parameters:
- Network Name: Avalanche C-Chain Mainnet
- New RPC URL:
https://api.avax.network/ext/bc/C/rpc - Chain ID:
43114 - Currency Symbol:
AVAX - Block Explorer URL:
https://snowtrace.io/
These values enable MetaMask to communicate securely with Avalanche’s consensus layer. Entering incorrect data—such as a wrong Chain ID or outdated RPC endpoint—can lead to failed transactions or lost funds.
Step-by-Step Guide to Add Avalanche C-Chain to MetaMask
Follow these clear steps to integrate the Avalanche network:
- Open your browser and click on the MetaMask extension icon.
- Click your account name in the top-right corner and select Settings.
- In the left sidebar, go to Networks > Add Network.
- Choose Add a network manually.
Fill in each field carefully:
- Network Name: Avalanche C-Chain Mainnet
- RPC URL: https://api.avax.network/ext/bc/C/rpc
- Chain ID: 43114
- Currency Symbol: AVAX
- Block Explorer URL: https://snowtrace.io/
- Click Save to confirm.
After saving, Avalanche C-Chain will appear in your network dropdown menu. You can now switch between Ethereum, Polygon, or Avalanche with a single click.

Testing Your Connection and Sending AVAX
Once added, test your setup:
- Switch to Avalanche C-Chain Mainnet in MetaMask.
- If your balance shows zero, send a small test amount of AVAX to your MetaMask address.
- Track the transaction on Snowtrace, Avalanche’s official block explorer.
- Confirm that your balance updates correctly in MetaMask.
Successful synchronization means you're fully connected and ready to interact with Avalanche-based dApps.
💡 Tip: Always double-check the active network before sending funds. Sending AVAX to an Ethereum address while on Ethereum network may result in permanent loss.
Common Issues and Troubleshooting Tips
Even with correct settings, users sometimes face issues. Here’s how to resolve them:
- "Unknown Network" or Connection Failure: Verify that all fields match exactly, especially the Chain ID (
43114) and RPC URL. - Slow or No Balance Update: Refresh MetaMask or try switching networks and back again. Clearing cache may also help.
- Transaction Stuck or Failing: Increase gas fees slightly if congestion occurs. Alternatively, check if the dApp supports dynamic fee estimation.
- RPC Endpoint Down: While rare, primary nodes can experience downtime. Consider using a backup RPC like

If problems persist, remove the network and re-add it using the steps above.
Frequently Asked Questions (FAQ)
Can I use the same MetaMask address on both Ethereum and Avalanche C-Chain?
Yes. Since both networks are EVM-compatible, your public address remains the same across chains. However, balances are separate—sending AVAX requires being on the Avalanche network.
What happens if I send AVAX to my wallet while on the Ethereum network?
If you send AVAX tokens while MetaMask is set to Ethereum Mainnet, the transaction will fail or be lost unless recovered via advanced cross-chain tools—often not feasible for average users.
Is there a mobile version of MetaMask that supports Avalanche?
Absolutely. The MetaMask mobile app allows manual addition of custom networks, including Avalanche C-Chain. The process mirrors desktop but uses touch navigation.
Are there alternatives to MetaMask for accessing Avalanche dApps?
Yes. Wallets like Trust Wallet, Coinbase Wallet, and Core Wallet also support Avalanche integration. However, MetaMask remains the most widely adopted due to its developer tools and browser extensions.
Why isn’t my AVAX balance showing after a transfer?
Delays can occur due to network latency or incorrect token selection. Ensure you're viewing the native AVAX token—not an ERC-20 version—and that you’re on the correct network.
Do I need AVAX for gas on the C-Chain?
Yes. All transactions on the Avalanche C-Chain require AVAX as gas, similar to ETH on Ethereum.
