Adding a custom network to your MetaMask wallet unlocks access to a wide range of decentralized applications (dApps), tokens, and blockchain ecosystems beyond Ethereum. Whether you're exploring Binance Smart Chain, Polygon, or emerging networks like KuCoin Community Chain, knowing how to manually configure these networks is essential for any crypto user. This guide walks you through the step-by-step process, explains key network parameters, and highlights best practices for secure and seamless integration.
Why Add Custom Networks to MetaMask?
MetaMask started as an Ethereum-only wallet, supporting ETH and ERC-20 tokens. However, the blockchain landscape has evolved dramatically. Today, multiple EVM-compatible (Ethereum Virtual Machine) chains offer faster transactions, lower fees, and unique dApp ecosystems. By adding these networks to MetaMask, you can:
- Swap tokens across different blockchains
- Interact with cross-chain dApps
- Reduce gas costs by using alternative networks
- Access exclusive DeFi and NFT projects

Keep in mind: MetaMask does not support Bitcoin (BTC) natively. You cannot send or swap BTC directly within the wallet. For Bitcoin transactions or BTC/USDT swaps, you’ll need to use a dedicated exchange.
Core Features of MetaMask Wallet
MetaMask is one of the most popular hot wallets in the cryptocurrency space—meaning it requires internet connectivity to operate. Its key functionalities include:
- Secure storage of Ethereum (ETH) and other EVM-based assets
- Built-in token swap feature across supported networks
- Direct connection to thousands of dApps (decentralized applications)
- Management of digital identity and private keys
- Sending and receiving crypto across multiple chains
Because it's a hot wallet, always ensure your device is secure and never share your seed phrase.
Step-by-Step: How to Add a Network to MetaMask
Follow this universal method to add any EVM-compatible blockchain network to your MetaMask wallet.
Step 1: Open MetaMask and Access Settings
Launch MetaMask via browser extension or mobile app. After logging in, click on your profile icon in the top-right corner, then select Settings.
Step 2: Navigate to Network Settings
In the Settings menu, go to Networks, then click Add Network. You’ll be prompted to enter specific configuration details.
Step 3: Enter Network Configuration Details
You must provide accurate information for the following fields:
- Network Name: The official name of the blockchain
- New RPC URL: The remote procedure call endpoint for the network
- Chain ID: A unique identifier for the blockchain (critical for compatibility)
- Currency Symbol: The native token symbol (e.g., BNB, MATIC)
- Block Explorer URL: The public blockchain explorer (e.g., BscScan, PolygonScan)
Once all fields are filled correctly, click Save. The network will now appear in your wallet’s network dropdown.
Frequently Asked Questions
Q: Is it safe to add custom networks to MetaMask?
A: Yes, as long as you use verified RPC URLs from official sources. Avoid entering network details from untrusted websites to prevent phishing attacks.
Q: Can I remove a network after adding it?
A: Absolutely. Go to Settings > Networks, find the network under "Custom Networks," and click "Delete."
Q: Why can’t I see my tokens after adding a network?
A: You may need to manually add the token contract address under the "Assets" tab. Also, ensure you're on the correct network in your wallet.
Q: Does adding a network expose my funds?
A: No. Adding a network only allows your wallet to communicate with that blockchain—it doesn’t grant access to your private keys or funds.
Q: What happens if I enter the wrong Chain ID?
A: Transactions may fail or be sent to an incompatible chain. Always double-check Chain IDs before saving.

Best Practices When Adding New Networks
- Verify All Details: Always cross-check Chain IDs and RPC URLs from official documentation.
- Use HTTPS RPC Endpoints: Ensures encrypted communication with the blockchain.
- Bookmark Trusted Sources: Save links to official explorers and developer portals.
- Test with Small Amounts First: Before large transactions, send a small test amount.
- Stay Updated: Networks may update their RPCs or parameters—recheck periodically.
