MetaMask Network Adder Tool – Add Any EVM Chain
Add Any EVM Network to MetaMask in Seconds
If you’ve ever tried to add a network manually in MetaMask, you already know how easy it is to make a small mistake. A wrong Chain ID or RPC link can stop the network from working entirely. This tool removes that friction. You just search for the network, confirm the request inside MetaMask, and you’re ready to use it. It works for major Layer 1 and Layer 2 chains, and it also lets you add custom EVM networks when needed.
How to Use the MetaMask Network Adder
Instead of entering technical details manually, you can use the tool above to add a network in just a few clicks. The process is straightforward and works the same way for most EVM chains. Just search for the network, confirm the request, and switch to it inside your wallet.
Step 1: Search for the Network
Type the network name or symbol into the search box. For example, you can enter “Polygon”, “ARB,” or “Base”. The tool will display the correct network details automatically.
Step 2: Click “Add to MetaMask”
Once the network appears, click the Add to MetaMask button. A wallet prompt will open, showing the network details. Review them and confirm the request.
Step 3: Switch to the Network
After the network is added, you can switch to it directly using the Switch button or from the network selector inside MetaMask.
Supported Networks in the Tool
The tool includes several widely used EVM chains so you can connect without entering details manually.
Major Layer 1 Networks
These are the base networks where transactions are validated directly on the main chain. Examples include Ethereum, BNB Smart Chain, Avalanche, and Polygon. They are commonly used for token transfers, staking, and DeFi applications.
Popular Layer 2 Networks
Layer 2 chains are built to improve speed and reduce transaction costs. Networks like Arbitrum, Optimism, Base, and zkSync fall into this category. They are widely used for trading, bridging, and on-chain applications with lower fees.
What Happens When You Add a Network to MetaMask
Once a network is added, it appears in your MetaMask network list. Your wallet address stays the same across all EVM chains, so you do not need a new wallet for each network. After switching, you can send tokens, interact with dApps, and pay transaction fees using the native token of that chain.
Manual Method: Add a Custom EVM Network
Some newer or smaller networks may not appear in preset lists. In those cases, you can still add them manually using the custom network form. This requires entering a few technical details provided by the network’s official documentation.
Required Details
To add a custom network, you need:
- Network name
- Chain ID
- RPC URL
- Native currency symbol
- Block explorer URL (optional)
Always copy this information from the official network website to avoid errors.
EVM vs Non-EVM Networks Explained
Not every blockchain works with MetaMask in the same way. Some follow the Ethereum Virtual Machine standard, while others use completely different architectures.
What Are EVM Networks
EVM networks follow the same core design as Ethereum. This means they share wallet compatibility, smart contract standards, and address formats. Examples include Ethereum, Polygon, Arbitrum, and Base. You can use the same MetaMask wallet across all of them.
What Are Non-EVM Networks
Non-EVM chains use different technologies and are not directly compatible with MetaMask. Bitcoin, Solana, XRP, and Cosmos are common examples. These usually require their own wallets or additional integrations such as MetaMask Snaps.
Common Issues When Adding Networks
Most network additions work instantly, but small mistakes or wallet settings can sometimes cause issues. These are the most common problems users run into and how to fix them.
MetaMask Not Detected
If the tool cannot detect MetaMask, make sure the extension is installed and unlocked. Refresh the page and reconnect your wallet if needed.
Network Already Added Error
If MetaMask shows that the network already exists, you do not need to add it again. Just switch to it from the network selector.
Wrong Chain ID or RPC
Incorrect network details can prevent the chain from working. Always copy the Chain ID and RPC from the official documentation instead of random sources.
Is It Safe to Add Networks to MetaMask
Adding a network is safe when the information comes from official sources. The main risk comes from malicious RPC endpoints, which can display incorrect balances or transaction data. To stay safe, always verify the Chain ID and RPC from the network’s official website or trusted documentation.
FAQs
How do I add a network to MetaMask?
Search for the network in the tool, click Add to MetaMask, and confirm the request inside your wallet.
Why can’t I see the network in MetaMask?
The network may not be added yet, or your wallet may still be connected to a different chain. Add the network and switch to it.
Can I use the same wallet on different networks?
Yes. All EVM networks use the same wallet address, so you can access multiple chains with one MetaMask wallet.
Do I need gas tokens for each network?
Yes. Every network uses its own native token for transaction fees, such as ETH on Ethereum or POL on Polygon.
