Avalanche (AVAX) is a leading platform for deploying smart contracts, building decentralized applications (dApps), and creating custom blockchains or subnets. While the native Avalanche Wallet supports storing AVAX tokens (ARC20) and transferring assets across chains, interacting with dApps requires a Web3 wallet like MetaMask.
MetaMask is a widely used cryptocurrency wallet that enables secure connections to decentralized applications, key management, and transaction execution. This guide provides a step-by-step process to connect the Avalanche network to your MetaMask wallet.
Why Connect Avalanche to MetaMask?
Integrating Avalanche with MetaMask allows you to:
- Access Avalanche dApps directly from your wallet.
- Manage ARC20 tokens alongside other cryptocurrencies.
- Execute transactions on a high-speed, low-cost blockchain.
- Utilize a familiar interface for cross-chain interactions.
MetaMask defaults to the Ethereum mainnet, so manual configuration is required to add Avalanche’s Contract Chain (C-Chain), which is compatible with the Ethereum Virtual Machine (EVM).
Step-by-Step Setup Guide
Install MetaMask
If you haven’t already, install the MetaMask extension for your browser or download the mobile app. Create a new wallet or import an existing one using your seed phrase.
Add Avalanche Network Manually
- Open MetaMask and click the network dropdown menu (usually显示 "Ethereum Mainnet").
- Select "Add Network" or "Custom RPC."
Enter the following Avalanche Mainnet settings:
- Network Name: Avalanche Mainnet C-Chain
- New RPC URL: https://api.avax.network/ext/bc/C/rpc
- ChainID: 43114 (or 0xa86a in hexadecimal)
- Currency Symbol: AVAX
- Block Explorer URL: https://cchain.explorer.avax.network
- Click "Save" to add the network.
Verify Connection
After saving, select "Avalanche Mainnet C-Chain" from the network dropdown. Your MetaMask is now connected to Avalanche’s C-Chain, ready for transactions and dApp interactions.
Transferring AVAX to MetaMask
Sending from Exchanges
Platforms like Binance and KuCoin support direct withdrawals to Avalanche C-Chain addresses:
- Copy your MetaMask Avalanche address.
- Paste it into the exchange’s withdrawal address field.
- Ensure the network is set to "AVAX C-Chain."
- Initiate the transfer with a small test amount first.
Cross-Chain Considerations
Avalanche has multiple chains: Exchange Chain (X-Chain), Platform Chain (P-Chain), and Contract Chain (C-Chain). MetaMask only interacts with the C-Chain. Always verify you’re using a C-Chain address for deposits or withdrawals to avoid lost funds.
Using Avalanche dApps with MetaMask
Once connected, you can:
- Swap tokens on decentralized exchanges (DEXs) like Pangolin.
- Provide liquidity in yield farming protocols.
- Mint and trade NFTs on Avalanche marketplaces.
- Participate in governance or staking platforms.

Troubleshooting Common Issues
- Tokens Not Showing? Confirm MetaMask is set to the Avalanche network. Add custom tokens manually if necessary.
- Transaction Failures? Ensure you have enough AVAX for gas fees, which are typically lower than Ethereum’s.
- Wrong Chain? Double-check RPC settings if connectivity issues persist.
Frequently Asked Questions
What is the Avalanche C-Chain?
The Contract Chain is Avalanche’s EVM-compatible blockchain, enabling Ethereum-like smart contracts and dApps. It uses AVAX for gas fees and supports fast, low-cost transactions.
Can I use the same address for Avalanche and Ethereum?
Yes, MetaMask uses the same address across all networks. However, assets are chain-specific—AVAX on the C-Chain is separate from Ethereum assets.
Is Avalanche more scalable than Ethereum?
Avalanche processes transactions in under 3 seconds with a throughput of ~4,500 TPS, offering greater scalability and lower fees than Ethereum’s current base layer.
How do I secure my Avalanche assets?
Use hardware wallets with MetaMask for enhanced security. Never share your seed phrase and verify all transaction details before confirming.
Can I stake AVAX through MetaMask?
Not directly. Staking requires sending AVAX to the P-Chain via the Avalanche Wallet. MetaMask is primarily for C-Chain dApp interactions.
What are subnets?
Subnets are custom blockchains within Avalanche that allow projects to define their own rules, tokens, and governance models while leveraging the network’s security.
Conclusion
Connecting Avalanche to MetaMask unlocks a vibrant ecosystem of dApps and DeFi opportunities. By configuring the C-Chain RPC settings correctly and transferring funds cautiously, you can seamlessly manage assets and engage with Avalanche’s high-performance network. Always start with small test transactions and prioritize security when interacting with decentralized platforms.
