MetaMask is a popular cryptocurrency wallet primarily used for interacting with the Ethereum blockchain. It supports all Ethereum-based tokens, including ERC-20 and ERC-721 standards. However, many users don't realize that MetaMask can also be connected to other blockchain networks, including Binance Smart Chain (BSC).
Connecting your MetaMask wallet to BSC opens up several possibilities. You'll be able to send and receive BNB, the native cryptocurrency of the Binance Smart Chain. Additionally, you can interact with decentralized applications (dApps) on the BSC network, swap tokens on decentralized exchanges like PancakeSwap, and participate in various yield farming opportunities—all through your familiar MetaMask interface.
This comprehensive guide will walk you through the entire process of connecting MetaMask to Binance Smart Chain, whether you're starting from scratch or already have a wallet setup.
Why Connect MetaMask to Binance Smart Chain?
Before we dive into the technical steps, let's explore why you might want to connect MetaMask to BSC in the first place.
Binance Smart Chain offers several advantages that have made it increasingly popular among cryptocurrency users:
- Lower transaction fees: Compared to Ethereum, BSC typically has significantly lower gas fees, making it more economical for smaller transactions and DeFi activities.
- Faster transactions: BSC's consensus mechanism allows for quicker block times, resulting in faster transaction confirmations.
- Ecosystem compatibility: Many Ethereum-based dApps have been ported to BSC, offering similar functionality with improved efficiency.
- Cross-chain opportunities: By connecting to multiple networks, you can take advantage of arbitrage opportunities and diverse yield farming strategies.
Having both Ethereum and Binance Smart Chain accessible through a single wallet interface like MetaMask simplifies managing assets across different blockchain ecosystems.
Prerequisites for Connecting MetaMask to BSC
Before beginning the connection process, make sure you have:
- The Chrome browser (or another Chromium-based browser like Brave)
- A basic understanding of cryptocurrency wallets and blockchain networks
- Your MetaMask recovery phrase (if you're restoring an existing wallet)
- A small amount of BNB for transaction fees (if you plan to perform transactions on BSC)
Step-by-Step Guide: Connecting MetaMask to Binance Smart Chain
Installing MetaMask and Creating a Wallet
If you haven't already installed MetaMask, begin by visiting the official MetaMask website. Always ensure you're downloading from the legitimate source to avoid phishing scams. Click the "Download" button and select "Install MetaMask for Chrome" (or your browser of choice).
After installation, you'll be prompted to either create a new wallet or import an existing one using your secret recovery phrase. If you're new to MetaMask, select "Create a Wallet." During this process, you'll receive a 12-word secret recovery phrase—this is critically important for accessing your wallet in the future. Write it down on paper and store it securely; never share it with anyone or store it digitally in an unsecured manner.
Complete the setup by verifying your recovery phrase when prompted. Once your wallet is created, you'll automatically be connected to the Ethereum Mainnet by default.
Accessing Network Settings
With your MetaMask wallet ready, you'll need to access the network settings to add Binance Smart Chain. Click on your profile icon in the top-right corner of the MetaMask interface. From the dropdown menu that appears, select "Settings."
In the Settings menu, navigate to the "Networks" option in the left sidebar. This section displays all the blockchain networks currently configured in your MetaMask wallet. By default, you'll see several Ethereum-based networks including the Ethereum Mainnet and various test networks.
Since Binance Smart Chain isn't preconfigured in MetaMask, you'll need to manually add it by clicking the "Add Network" button.
Configuring Binance Smart Chain Network Parameters
After clicking "Add Network," you'll see several fields that need to be filled with specific information to properly connect to Binance Smart Chain:
- Network Name: Enter "Smart Chain"
- New RPC URL: Use "https://bsc-dataseed.binance.org/"
- Chain ID: Enter "56"
- Currency Symbol: Enter "BNB"
- Block Explorer URL: Enter "https://bscscan.com"
Double-check all information for accuracy, as incorrect network parameters could lead to failed transactions or loss of funds. Once verified, click "Save" to add the Binance Smart Chain network to your MetaMask wallet.
Upon successful addition, your MetaMask will automatically switch to the BSC network. You can confirm this by checking the network dropdown in the top center of your wallet interface—it should now display "Smart Chain" instead of "Ethereum Mainnet."
Verifying Your Connection
After connecting to Binance Smart Chain, it's important to verify that everything is working correctly. Your wallet should now display BNB as the default currency instead of ETH. If you already have BNB in your wallet, your balance should appear correctly.
To further verify your connection, try viewing your wallet address on the BSCScan block explorer by clicking the three dots next to your account name and selecting "View on block explorer." This should open your wallet address on bscscan.com, confirming that you're properly connected to the Binance Smart Chain network.
Switching Between Networks
One of MetaMask's strengths is its ability to easily switch between different blockchain networks. After adding Binance Smart Chain, you can toggle between Ethereum and BSC by clicking the network dropdown at the top of your MetaMask interface and selecting your desired network.
Remember that each network has its own native currency (ETH for Ethereum, BNB for BSC) and you'll need the appropriate cryptocurrency to pay for transaction fees on each network. Assets exist separately on each chain—your Ethereum-based tokens won't appear when you're connected to BSC, and vice versa.
Troubleshooting Common Connection Issues
Sometimes users encounter problems when connecting MetaMask to Binance Smart Chain. Here are some common issues and their solutions:
- Incorrect network parameters: Double-check that you've entered all fields correctly, particularly the RPC URL and Chain ID.
- Pending transactions: If transactions seem stuck, try resetting your account in MetaMask's Advanced Settings (note: this will clear your transaction history but won't affect your balances or keys).
- Balance not showing: If your BNB balance isn't appearing, ensure you're connected to the correct network and that you've added the custom BEP-20 token if necessary.
- RPC URL issues: If the primary RPC URL is experiencing issues, try using an alternative BSC RPC endpoint.

Frequently Asked Questions
Can I use the same MetaMask address for both Ethereum and Binance Smart Chain?
Yes, your MetaMask address remains the same across all networks. The same public and private keys control your addresses on every blockchain. However, your assets and transaction history are separate on each network.
Why isn't my BNB balance showing after connecting to BSC?
If you had BNB in your wallet before adding the BSC network, it should appear automatically. If you recently transferred BNB to your address, try refreshing MetaMask or checking your address on BSCScan to confirm the transaction was successful.
Do I need different cryptocurrencies for gas fees on Ethereum vs. BSC?
Yes, Ethereum transactions require ETH for gas fees, while Binance Smart Chain transactions require BNB. Make sure you have the appropriate cryptocurrency for the network you're using.
Can I transfer assets directly between Ethereum and Binance Smart Chain?
Not directly through MetaMask. To move assets between chains, you'll typically need to use a bridge service or exchange that supports both networks.
Is it safe to add custom networks like BSC to MetaMask?
Yes, as long as you use the correct network parameters from official sources. Always verify network details through multiple reputable sources before adding any custom network to your wallet.
What should I do if I entered wrong network parameters?
