MetaMask, launched in 2016, has become the go-to wallet for over 30 million monthly active users interacting with EVM-based assets. Its simplicity, cross-device compatibility, and extensive blockchain support make it ideal for both beginners and seasoned crypto enthusiasts (though advanced users may prefer hardware wallets for cold storage).
Understanding MetaMask's Network Compatibility
By default, MetaMask supports:
- Ethereum mainnet
- Testnets (Ropsten, Kovan, Rinkeby, Goerli)
👉 Discover how MetaMask compares to other wallets
Key Limitation: MetaMask only works with EVM-compatible chains. For non-EVM networks like Solana or NEAR, you'll need native wallets—though some offer EVM sidechains (e.g., Aurora for NEAR) that MetaMask can access.
Manual Network Addition: Step-by-Step
To add a new blockchain, you'll need these details:
- Network Name (e.g., "BNB Chain")
- RPC URL (Protocol address for blockchain interaction)
- Chain ID (Unique network identifier)
- Currency Symbol (Native token ticker like BNB)
- Block Explorer URL (Optional; e.g., BscScan for BNB Chain)
Adding Networks via MetaMask Interface:
- Click your profile avatar → Settings → Networks
- Select "Add New Network"
- Enter the required details (see table below for popular chains)
| Blockchain | RPC URL | Chain ID | Currency Symbol |
|---|---|---|---|
| BNB Chain | https://bscrpc.com | 56 | BNB |
| Polygon | https://polygon-rpc.com | 137 | MATIC |
| Avalanche C-Chain | https://api.avax.network/ext/bc/C | 43114 | AVAX |
Automated Network Addition Tools
For easier setup, try these methods:
1. Chainlist.org
- Connect MetaMask
- Search your target network
- Click "Add to MetaMask" → Approve the RPC details
👉 Explore top EVM chains on Chainlist
2. dApp Prompts
Some decentralized apps (like Uniswap on Optimism) automatically prompt you to add their network when you first connect.
Future Upgrades: Bitcoin & Non-EVM Support
MetaMask plans to introduce "Snaps"—isolated extensions that will enable:
- Bitcoin compatibility
- Support for non-EVM chains
- Third-party functionality upgrades
Currently available only on MetaMask Flask (developer beta).
FAQ
Q: Can MetaMask store Bitcoin?
A: Not yet, but Bitcoin support is coming via Snaps.
Q: Is manually adding networks safe?
A: Always verify RPC URLs from official sources to avoid phishing.
Q: Why can't I see my tokens after adding a network?
A: You may need to manually add the token contract address under "Import Token."
Q: Do I need separate wallets for non-EVM chains?
A: Yes—chains like Solana require wallets like Phantom.
Pro Tips
- Bookmark RPC Info for verified network details
- Double-check chain IDs—incorrect IDs can lead to lost funds
- Use testnets first to practice network additions
