In today’s fast-evolving cryptocurrency landscape, MetaMask has emerged as one of the most widely used digital wallets. Originally designed for Ethereum and ERC-20 tokens, MetaMask now supports multiple blockchain networks — including Binance Smart Chain (BSC). This flexibility allows users to manage BNB (Binance Coin) directly within their MetaMask wallet, enabling seamless interaction with decentralized applications (DApps), DeFi protocols, and NFT marketplaces built on BSC.
This comprehensive guide walks you through how to add BNB to MetaMask, configure the Binance Smart Chain network, and implement essential security practices to protect your digital assets.
Understanding MetaMask and BNB
MetaMask is a non-custodial cryptocurrency wallet that lets users store, send, receive, and interact with Ethereum-based assets and compatible blockchains. Available as a browser extension and mobile app, it provides direct access to the decentralized web (Web3), allowing secure interactions with DApps without exposing private keys.
BNB (Binance Coin) started as an ERC-20 token on Ethereum but later transitioned to its own blockchain — Binance Chain — and expanded across Binance Smart Chain. Today, BNB powers transactions on BSC, pays for gas fees, participates in token sales, and serves as collateral in various DeFi platforms.
Adding BNB to MetaMask unlocks full functionality on BSC-based ecosystems. Whether you're trading on PancakeSwap, staking in yield farms, or minting NFTs, having BNB readily available in your wallet is essential.

Step-by-Step: How to Add BNB to MetaMask
Follow these clear steps to integrate BNB into your MetaMask wallet by adding the Binance Smart Chain network.
1. Install and Set Up MetaMask
If you haven’t already:
- Visit the official MetaMask website and install the browser extension or download the mobile app.
- Create a new wallet and securely back up your 12-word recovery phrase — this is critical for recovering access if you lose your device.
- Set a strong, unique password to encrypt your wallet locally.
🔐 Never share your seed phrase with anyone. Scammers often pose as support agents to steal it.
2. Add Binance Smart Chain (BSC) Network to MetaMask
MetaMask doesn’t include BSC by default, so you must manually add it:
- Open MetaMask and click the network dropdown (usually shows “Ethereum Mainnet”).
- Select "Add Network" > "Add a Network Manually".
Enter the following BSC Mainnet RPC settings:
- Network Name: Binance Smart Chain
- New RPC URL:
https://bsc-dataseed.binance.org/ - Chain ID:
56 - Currency Symbol:
BNB - Block Explorer URL:
https://bscscan.com
- Click Save.
Once added, your MetaMask will switch to the Binance Smart Chain network, and all subsequent actions will occur on BSC.
3. Acquire and Display BNB in Your Wallet
After setting up the network:
- Purchase BNB from a centralized exchange like Binance or OKX.
- Withdraw BNB to your MetaMask address using the BSC (BEP-20) network — not ERC-20, unless bridging.
- Confirm the transaction on BscScan using your wallet address.
- In MetaMask, ensure you're on the Binance Smart Chain network — your BNB balance should appear automatically.
⚠️ Always double-check withdrawal networks. Sending ERC-20 BNB to a BEP-20 address (or vice versa) without proper bridging may result in lost funds.
Best Practices for Securing Your BNB in MetaMask
Managing crypto assets comes with responsibility. Here are proven strategies to enhance security:
✅ 1. Safeguard Your Recovery Phrase
Your 12-word seed phrase grants full control over your wallet. Store it offline — preferably on metal or paper — and never save it digitally (no screenshots, cloud storage, or messaging apps).
✅ 2. Use Hardware Wallet Integration
For maximum protection, link MetaMask with a hardware wallet like Ledger or Trezor. This setup keeps private keys physically isolated while allowing convenient DApp access through MetaMask.

✅ 3. Beware of Phishing Attacks
Always verify URLs before connecting your wallet. Fake versions of PancakeSwap, Trust Wallet, or MetaMask login pages are common. Bookmark official sites and avoid clicking suspicious links in emails or social media.
✅ 4. Regularly Update Software
Keep your MetaMask extension, browser, and operating system updated to patch vulnerabilities and benefit from enhanced security features.
✅ 5. Limit Exposure with Fund Segregation
Only keep small amounts of BNB in MetaMask for daily use. Store the majority of your holdings in cold storage (hardware wallets) to reduce risk from online threats.
Frequently Asked Questions (FAQ)
Q: How do I check my BNB balance in MetaMask?
A: After adding the Binance Smart Chain network, your BNB balance should display automatically under the "Assets" tab. If not visible, ensure you're on the correct network and that funds were sent via BEP-20.
Q: Can I send BNB from MetaMask to another wallet?
A: Yes. Make sure you're on the Binance Smart Chain network, then click “Send,” enter the recipient’s address, specify the amount, and confirm the gas fee before submitting.
Q: What’s the difference between ERC-20 BNB and BEP-20 BNB?
A: ERC-20 BNB runs on Ethereum; BEP-20 BNB operates on Binance Smart Chain. They’re technically different tokens with separate addresses and networks. Always match the network type when sending or receiving.
Q: Why can’t I see my BNB after transferring?
A: First, confirm the transfer used the BEP-20 (BSC) network. Then check your network selection in MetaMask — if it’s set to Ethereum Mainnet instead of BSC, switch networks manually.
Q: Is it safe to use MetaMask for storing large amounts of BNB?
A: While MetaMask is secure for regular use, it's best suited for smaller transaction balances. For long-term storage of significant assets, use a hardware wallet paired with MetaMask.
Q: Do I need BNB in my wallet for every transaction?
A: Yes — just like ETH on Ethereum, you need native BNB to pay gas fees for any transaction or interaction on Binance Smart Chain.
Final Thoughts
Adding BNB to MetaMask is a straightforward process that opens doors to a vibrant ecosystem of DeFi, gaming, and NFT platforms on Binance Smart Chain. By following the correct configuration steps and adopting robust security habits — such as backing up your seed phrase, avoiding phishing scams, and integrating hardware wallets — you can confidently manage your digital assets.
Whether you're new to Web3 or expanding your multi-chain portfolio, mastering MetaMask’s capabilities empowers you to take full advantage of decentralized finance.
