Connecting your MetaMask wallet to the BNB Smart Chain (BSC) opens the door to a fast, low-cost blockchain ecosystem teeming with decentralized applications (dApps), yield farming opportunities, and token swaps. Originally designed for Ethereum, MetaMask has evolved into a versatile Web3 gateway that supports multiple blockchains — including BSC.
In this guide, we’ll walk you through how to seamlessly configure MetaMask for BNB Smart Chain, whether you're using the browser extension or mobile app. You’ll also learn how to use the BSC testnet to practice transactions risk-free.
Why Use BNB Smart Chain with MetaMask?
BNB Smart Chain combines the security of Proof-of-Staked-Authority (PoSA) with Ethereum Virtual Machine (EVM) compatibility, making it easy for developers and users familiar with Ethereum to transition. With significantly lower transaction fees and faster block times than Ethereum, BSC is ideal for DeFi enthusiasts, NFT traders, and Web3 explorers.
MetaMask serves as your digital identity and asset manager across these ecosystems. By connecting it to BSC, you gain access to popular platforms like PancakeSwap, Venus, and BakerySwap — all without needing a new wallet.

Step-by-Step: Setting Up MetaMask
Before linking to BNB Smart Chain, ensure MetaMask is installed and set up on your device.
1. Install MetaMask
Visit the official MetaMask website and download the version for your platform:
- Browser users: Available as an extension for Chrome, Firefox, Brave, and Edge.
- Mobile users: Download from the App Store (iOS) or Google Play (Android).
Never install MetaMask from third-party sources — always verify the URL is metamask.io.2. Create a New Wallet
Launch the extension or app and select "Create a Wallet". Follow the prompts to set a strong password.
3. Secure Your Seed Phrase
You’ll be shown a 12-word recovery phrase (also known as a seed phrase). This is the master key to your wallet.
- Write it down on paper.
- Store it in a secure, offline location.
- Never share it with anyone — not even support staff.
Re-enter the words to confirm backup.
Once verified, your wallet is ready to use.
Connect MetaMask to BNB Smart Chain (Mainnet)
Now that your wallet is created, let’s switch from Ethereum to BNB Smart Chain.
Option 1: Add BSC via Network List (Recommended)
MetaMask includes pre-configured networks for major blockchains.
- Click the network dropdown (top-left), usually showing “Ethereum Mainnet.”
- Select “Add network”, then choose “BNB Smart Chain” from the list.
- Review the details and click “Approve”, then “Switch Network”.
Your wallet is now connected to BSC mainnet.
Note: If BNB Chain isn't listed, proceed with manual configuration below.
Option 2: Manually Add BNB Smart Chain
If the network isn’t auto-detected, add it manually:
- From the network selector, click “Add network” > “Add a network manually”.
- Enter the following parameters:
- Network Name: BNB Smart Chain
- New RPC URL:
https://bsc-dataseed.binance.org/ - Chain ID:
56 - Currency Symbol:
BNB - Block Explorer URL:
https://bscscan.com
- Click “Save”.
You’re now live on BNB Smart Chain.
Fund Your Wallet on BSC
To interact with dApps, you need BNB for gas fees.
- Transfer BNB from an exchange like Binance using the BEP-20 network.
- Ensure your withdrawal address matches your MetaMask address.
- Always send a small test transaction first.
Once confirmed, you can begin exploring DeFi platforms, staking pools, or NFT marketplaces on BSC.

Test Your Setup: Using BNB Smart Chain Testnet
Before risking real funds, practice on the BSC testnet using free test tokens.
Step 1: Add BSC Testnet to MetaMask
- Go to Settings > Networks > Add Network.
- Enter these testnet parameters:
- 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 URL:
https://testnet.bscscan.com
Click “Save”.
Step 2: Get Free Test BNB
- Copy your MetaMask wallet address.
- Visit the BNB Chain Faucet.
- Paste your address and click “Give me BNB” (0.1 tBNB).
- Wait a few seconds — funds will appear in your wallet.
Step 3: Make a Test Transaction
- In MetaMask, click “Send”.
- Paste any valid BSC testnet address (e.g., from BscScan Testnet).
- Enter an amount (e.g., 0.05 tBNB).
- Confirm gas fee and click “Confirm”.
Check the “Activity” tab — within seconds, your transaction should be confirmed.
This simulates real-world usage without financial risk.
Key Considerations When Switching Blockchains
While MetaMask makes switching networks seamless, remember:
- Tokens are not automatically transferable between chains. Sending ERC-20 tokens to a BEP-20 address (or vice versa) may result in permanent loss.
- Use a trusted cross-chain bridge, such as the BNB Bridge, to move assets between Ethereum and BSC safely.
- Always double-check the active network before confirming transactions.
Frequently Asked Questions (FAQ)
Q: Can I use the same MetaMask wallet for Ethereum and BNB Smart Chain?
Yes. MetaMask supports multiple EVM-compatible chains. Simply switch networks within the app — your private keys remain unchanged.
Q: Is there a difference between BNB Chain and BNB Smart Chain?
BNB Chain refers to the entire ecosystem, including both BNB Beacon Chain (governance) and BNB Smart Chain (smart contracts). When using MetaMask, you're connecting to BNB Smart Chain.
Q: Why can’t I see my tokens after switching networks?
Tokens are chain-specific. If you’ve bridged assets from Ethereum to BSC but don’t see them, ensure you’re on the correct network and try adding the token contract manually via “Add Token” in MetaMask.
Q: Do I need real BNB to use the testnet?
No. The testnet uses tBNB, which is free and only valid for testing purposes.
Q: What should I do if MetaMask shows “Network Error”?
Verify your RPC URL and internet connection. Try switching to a different RPC provider if issues persist.
Q: Are transactions on BSC irreversible?
Yes — like all blockchains, confirmed transactions cannot be undone. Always review recipient addresses carefully.
