How to Add a Network to MetaMask

·

Adding a new network to your MetaMask wallet unlocks access to a broader range of decentralized applications (dApps), tokens, and blockchain ecosystems. Whether you're exploring Layer 2 solutions like Arbitrum or emerging EVM-compatible chains such as the Flare Network, custom network integration enhances your crypto experience. This guide walks you through the process step by step, ensuring a secure and seamless setup.

Understanding Custom Networks in MetaMask

MetaMask is more than just an Ethereum wallet — it's a gateway to the decentralized web. By default, it connects to the Ethereum mainnet, but its real power lies in its flexibility. You can add custom networks to interact with other blockchains that support the Ethereum Virtual Machine (EVM).

However, not all blockchains are compatible. Only EVM-based networks — including both Layer 1 and Layer 2 chains — can be added. Examples include Binance Smart Chain, Polygon, Avalanche C-Chain, Optimism, and Fantom. Each requires specific configuration details known as RPC (Remote Procedure Call) settings, which tell MetaMask how to communicate with the network.

Can You Add a Custom Network to MetaMask?

Yes, absolutely. MetaMask allows users to manually or automatically add EVM-compatible networks using:

While manual entry is possible, it carries risks if incorrect details are used — such as lost funds or phishing attacks. That’s why experts recommend using trusted tools like ChainList for safe and verified network connections.

Step-by-Step: How to Add a Network to MetaMask

The safest and most user-friendly method to add a network is via ChainList, a community-vetted platform that curates official RPC endpoints for thousands of EVM chains.

Step 1: Open ChainList

Go to chainlist.org in your browser. Make sure you're on the legitimate site to avoid scams.

Step 2: Connect Your MetaMask Wallet

Click “Connect Wallet” and select MetaMask from the options. Confirm the connection request in your wallet extension.

Step 3: Search for Your Desired Network

Use the search bar at the top to find the blockchain you want — for example, "Avalanche", "Polygon", or "Fantom". The list includes both mainnets and testnets.

Step 4: Add the Network

Once you locate the correct network, click the “Add to MetaMask” button. A pop-up will appear in your wallet asking for confirmation. Review the details and click “Next”, then “Add Network”.

That’s it! The network is now active in your MetaMask wallet, and you can begin interacting with dApps on that chain.

🔐 Always double-check Chain IDs and RPC URLs even when using trusted platforms. Security starts with awareness.

Frequently Asked Questions

Q: Is it safe to add custom networks to MetaMask?
A: Yes, as long as you use verified sources like ChainList or official documentation from the blockchain team. Avoid entering RPC details from untrusted websites or social media posts.

Q: What happens if I enter the wrong Chain ID?
A: Transactions may fail or not be broadcasted to the correct network. In rare cases, tokens could be sent to non-existent addresses. Always verify Chain ID before confirming.

Q: Can I remove a network from MetaMask?
A: Yes. Go to MetaMask Settings > Networks > Connected Sites, find the network, and click “Remove”. This won’t affect your funds — only the connection.

Q: Do I need separate ETH for each network?
A: Yes. Each EVM chain operates independently. For example, Ethereum gas fees require ETH on Ethereum, while BSC uses BNB for gas. Cross-chain bridges are needed to move assets between networks.

Q: Why doesn’t my token show up after switching networks?
A: Tokens are network-specific. If you’ve bridged assets correctly but don’t see them, manually add the token contract address under the "Tokens" tab in MetaMask.

Can You Add Multiple Networks to MetaMask?

Absolutely. MetaMask supports an unlimited number of custom networks. You can switch between them instantly using the network dropdown at the top of your wallet interface.

This flexibility allows you to:

Over time, many users accumulate dozens of networks. To keep things organized, consider renaming unfamiliar entries or removing unused ones periodically.
