Written by

MetaMask is a popular cryptocurrency wallet that provides access to a wide range of blockchain applications and decentralized finance (DeFi) platforms. Originally designed for the Ethereum network, MetaMask can also be configured to work with other blockchains, including BNB Smart Chain (BSC).

This guide will walk you through the process of setting up MetaMask and connecting it to BNB Smart Chain, allowing you to explore decentralized applications (DApps) on the BSC ecosystem.

What Is MetaMask?

MetaMask is a non-custodial wallet available as a browser extension (Chrome, Firefox, Brave) and a mobile app (iOS & Android). It enables users to:

  • Store and manage crypto assets
  • Interact with decentralized applications (DApps)
  • Conduct secure transactions on supported blockchains

👉 Learn more about MetaMask and its features

Step 1: Install MetaMask

  1. Visit the official MetaMask download page.
  2. Select your preferred platform (browser extension or mobile).
  3. Follow the installation instructions.

Note: Ensure you download MetaMask only from the official website to avoid phishing scams.

Step 2: Create or Import a Wallet

Once installed:

  1. Click “Create a New Wallet.”
  2. Set a strong password (this protects your device but does not recover funds).
  3. Back up your Secret Recovery Phrase (seed phrase)—this is crucial for wallet recovery.
  4. Write it down on paper (never store it digitally).
  5. Never share it with anyone.
  6. Confirm your seed phrase by entering the words in order.
  7. Your wallet is now ready!

Step 3: Connect MetaMask to BNB Smart Chain

By default, MetaMask connects to the Ethereum Mainnet. To switch to BNB Smart Chain, follow these steps:

Method 1: Add BSC Automatically

  1. Click the network dropdown (top-left, usually shows “Ethereum Mainnet”).
  2. Select “Add Network.”
  3. Find “BNB Chain” in the list and click “Add.”
  4. MetaMask will auto-fill these details:
Parameter Value for BNB Smart Chain (Mainnet)
Network Name BNB Smart Chain
New RPC URL https://bsc-dataseed.binance.org/
Chain ID 56
Currency Symbol BNB
Block Explorer https://bscscan.com
  1. Click “Save.”

Method 2: Add BSC Manually

If BSC doesn’t appear in the list:
1. Click “Add Network Manually.”
2. Enter the details from the table above.
3. Click “Save.”

Step 4: Using BNB Smart Chain Testnet

For testing without real funds, you can connect to the BNB Smart Chain Testnet:

  1. Follow the same steps as above but use these parameters:
Parameter Value for BSC Testnet
Network Name BNB Smart Chain Testnet
New RPC URL https://data-seed-prebsc-1-s1.binance.org:8545/
Chain ID 97
Currency Symbol tBNB
Block Explorer https://testnet.bscscan.com
  1. Get free testnet BNB from the BNB Faucet.

Step 5: Send a Test Transaction (Optional)

  1. Copy your MetaMask wallet address.
  2. Request testnet BNB from the faucet.
  3. Send a small amount of tBNB to another testnet address.
  4. Verify the transaction on BscScan Testnet.

FAQs

1. Can I use the same wallet for Ethereum and BSC?

Yes! MetaMask supports multiple networks. You can switch between Ethereum, BSC, and others.

2. Why do I need BNB in my wallet?

BNB is used to pay gas fees for transactions on BSC. Without BNB, you can’t send tokens or interact with DApps.

3. Is BNB Smart Chain safe?

BNB Smart Chain is a reputable blockchain, but always verify contracts and DApps before interacting with them.

4. Can I transfer ETH directly to BSC?

No. You must use a blockchain bridge (like Binance Bridge) to move assets between Ethereum and BSC.

5. What if I lose my seed phrase?

Without the seed phrase, you cannot recover your wallet. Always store it securely offline.

6. How do I add custom tokens (e.g., BEP-20 tokens)?

  • Go to “Assets” > “Import Tokens.”
  • Enter the token contract address (find it on BscScan).

Conclusion

Connecting MetaMask to BNB Smart Chain unlocks access to a thriving DeFi ecosystem. Whether you’re trading, staking, or exploring DApps, BSC offers fast and affordable transactions compared to Ethereum.

Remember:
– Secure your seed phrase at all costs.
– Always verify transaction details before confirming.
– Use testnet for practice before using real funds.
