How to Add a Network to MetaMask

·

Adding a new blockchain network to your MetaMask wallet unlocks access to a broader range of decentralized applications (dApps), tokens, and ecosystems. Whether you're exploring Layer 2 solutions like Arbitrum or emerging EVM-compatible chains such as the Flare Network, custom network integration is a fundamental skill for any crypto user. This guide walks you through the process step by step, explains key requirements, and ensures you stay secure while expanding your wallet’s capabilities.

Understanding EVM Compatibility

Before attempting to add a new network, it’s essential to understand that MetaMask only supports networks compatible with the Ethereum Virtual Machine (EVM). This includes most modern blockchains designed to run Ethereum-based smart contracts. Examples include:

These chains use similar architecture to Ethereum, allowing seamless dApp interaction through tools like MetaMask. Non-EVM chains such as Solana or Bitcoin cannot be added directly.

Can You Add a Custom Network to MetaMask?

Yes — MetaMask allows users to manually add custom networks using RPC (Remote Procedure Call) details, which include:

However, manually entering these details carries risks if sourced from untrusted websites. An incorrect Chain ID or malicious RPC URL could lead to lost funds or phishing attacks.

For this reason, we recommend using ChainList, a community-vetted platform that verifies and authenticates RPC endpoints for thousands of EVM-compatible networks — both mainnets and testnets.

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

ChainList simplifies the process by eliminating the need to copy-paste sensitive configuration data. Here’s how to use it safely:

1. Visit ChainList.org

Open your browser and navigate to chainlist.org. The site features an intuitive interface listing hundreds of supported networks.

2. Connect Your MetaMask Wallet

Click the “Connect Wallet” button at the top right corner. Select MetaMask when prompted and confirm the connection in your wallet extension.

🔐 Always ensure you’re on the official ChainList website to avoid phishing scams.

3. Search for Your Desired Network

Use the search bar at the top to type in the name of the blockchain you want to add — for example, “Flare Network,” “Arbitrum One,” or “Polygon.”

A dropdown list will appear with matching results. Click on the correct network.

4. Add the Network to MetaMask

Once selected, a “Connect” button will appear. Click it, and MetaMask will automatically prompt you to approve adding the network with pre-verified settings.

Review the details carefully, then click “Approve” followed by “Switch Network” to begin using it immediately.

✅ That’s it — your new network is now active in MetaMask.

👉 Access verified blockchain networks with confidence and ease.

Frequently Asked Questions (FAQ)

Q: Is it safe to add custom networks to MetaMask?
A: Yes, as long as you use trusted sources like ChainList or official project documentation. Avoid entering RPC URLs from forums, social media, or unknown websites.

Q: What happens if I enter the wrong Chain ID?
A: Transactions may fail or become stuck. In rare cases, tokens sent to incompatible networks can be permanently lost. Always double-check configuration data before confirming.

Q: Can I remove a network from MetaMask?
A: Absolutely. Go to MetaMask Settings > Networks > Connected Sites, find the network, and click “Delete.” This removes it from your network list without affecting your funds.

Q: Do added networks affect my private keys or seed phrase?
A: No. Your private keys remain unchanged. Adding a network only changes which blockchain your wallet connects to — not your account security.

Q: Why can’t I see my tokens after switching networks?
A: Tokens are network-specific. If you switch from Ethereum to Polygon, for instance, your Ethereum-based tokens won’t appear until you switch back. Make sure you're on the correct network when checking balances.

Can You Add Multiple Networks to MetaMask?

Yes — you can add an unlimited number of EVM-compatible networks to your MetaMask wallet. There’s no technical limit, and managing multiple chains is part of what makes MetaMask so powerful.

Whether you're testing dApps on Goerli or deploying assets across Avalanche and Optimism, having multiple networks configured lets you switch seamlessly between ecosystems.
