Adding Binance Smart Chain (BSC) to your MetaMask wallet unlocks a powerful gateway to faster, low-cost decentralized applications and token transactions. As one of the most widely used crypto wallets, MetaMask supports multiple blockchain networks beyond Ethereum — and Binance Smart Chain is among the most valuable to integrate due to its speed, affordability, and thriving dApp ecosystem.
This comprehensive guide walks you through everything you need to know about connecting Binance Smart Chain to MetaMask, from understanding the basics to troubleshooting common issues — all while keeping your experience secure and seamless.
Understanding MetaMask and Binance Smart Chain
Before diving into the setup process, it’s essential to understand the two core components involved: MetaMask and Binance Smart Chain.
What Is MetaMask?
MetaMask is a non-custodial cryptocurrency wallet available as a browser extension and mobile app. It allows users to store, send, receive, and interact with decentralized applications (dApps) on Ethereum-compatible blockchains. Originally designed for Ethereum, MetaMask supports any network that runs on the Ethereum Virtual Machine (EVM) — including Binance Smart Chain.
With its intuitive interface and strong security model, MetaMask has become a go-to tool for both beginners and experienced users in the Web3 space.

What Is Binance Smart Chain?
Binance Smart Chain (now known as BNB Smart Chain) is a parallel blockchain developed by Binance that enables smart contract execution and supports EVM-based dApps. It operates alongside the Binance Chain but focuses on programmability and decentralized finance (DeFi) innovation.
Key advantages of BSC include:
- Low transaction fees compared to Ethereum
- Fast block times (around 3 seconds)
- Full EVM compatibility, making it easy to port Ethereum dApps
- Native token BNB used for gas fees and staking
By adding Binance Smart Chain to MetaMask, you can access popular DeFi platforms like PancakeSwap, stake tokens, participate in yield farming, and more — all with significantly lower costs than on Ethereum.
Step-by-Step Guide: Adding Binance Smart Chain to MetaMask
Follow these simple steps to connect Binance Smart Chain to your MetaMask wallet manually.
Step 1: Prepare Your MetaMask Wallet
Ensure your MetaMask extension or app is installed and set up. If you're new:
- Install MetaMask from metamask.io
- Create a new wallet
- Securely back up your 12-word recovery phrase
Never share your seed phrase with anyone — it grants full access to your funds.
Step 2: Add Binance Smart Chain Network Manually
Since BSC isn’t preloaded in older versions of MetaMask, you’ll need to add it as a custom RPC network:
- Open MetaMask
- Click the network dropdown at the top (e.g., "Ethereum Mainnet")
- Select "Add Network" > "Add a Network Manually"
Enter the following details:
- Network Name: BSC Mainnet
- New RPC URL:
https://bsc-dataseed1.binance.org/ - Chain ID:
56 - Currency Symbol:
BNB - Block Explorer URL:
https://bscscan.com
- Click "Save"
Once saved, MetaMask will switch to the BSC network automatically.
🔐 Pro Tip: Always verify the RPC URL and Chain ID from official sources. Entering incorrect details may result in lost funds or failed transactions.

Switching Between Ethereum and Binance Smart Chain
One of MetaMask’s key features is the ability to switch between different blockchain networks effortlessly.
To change networks:
- Open MetaMask
- Click the current network name (e.g., "Ethereum Mainnet")
- Select "BSC Mainnet" from the list
You’ll now be operating on the Binance Smart Chain. Your wallet address remains the same across chains, but your token balances differ depending on the network.
⚠️ Important: Assets do not automatically transfer between chains. For example, ETH cannot be used on BSC, and BNB on Ethereum (as BEP-20) must be bridged properly.
Managing BNB Tokens in MetaMask
BNB is the native cryptocurrency of Binance Smart Chain and is required to pay transaction fees (gas). Here's how to use it effectively:
How to Receive BNB
- Switch MetaMask to BSC Mainnet
- Click "Receive"
- Share your wallet address with the sender
Ensure the sender sends BEP-20 BNB (not BEP-2 or ERC-20), as only BEP-20 works natively on BSC via MetaMask.
How to Send BNB
- Switch to BSC Mainnet
- Click "Send"
- Enter recipient address and amount
- Confirm transaction (fee paid in BNB)
Always keep a small amount of BNB in your wallet when using BSC dApps — without it, you won’t be able to execute any transactions.
Interacting With dApps on Binance Smart Chain
With BSC added to MetaMask, you can now explore thousands of decentralized applications.
Accessing dApps
- Visit a BSC-compatible dApp (e.g., PancakeSwap, Venus, or Beefy Finance)
- Click “Connect Wallet”
- Choose MetaMask
- Approve connection and ensure network is set to BSC Mainnet
You’re now ready to trade, stake, farm, or lend directly through the dApp interface.
Why BNB Is Crucial for dApp Usage
Beyond gas fees, many dApps require BNB for:
- Paying service fees
- Participating in token sales
- Staking for rewards
- Providing liquidity
Having sufficient BNB ensures uninterrupted interaction across the BSC ecosystem.
Common Issues and Best Practices
While integrating BSC into MetaMask is straightforward, users often encounter avoidable pitfalls.
Issue 1: Network Not Loading or Transactions Failing
Cause: Incorrect RPC URL or unstable node connection
Solution: Try alternative RPC endpoints like:
https://bsc-dataseed2.defibit.io/https://bsc-dataseed3.ninicoin.io/
You can edit the RPC URL under Network Settings in MetaMask.
Issue 2: Unable to See BNB Balance
Cause: Wallet still set to Ethereum network
Fix: Switch network to BSC Mainnet — balances are network-specific.
Issue 3: Accidental Transactions on Wrong Network
Never send tokens meant for one chain (e.g., ERC-20) to a wallet address on another (e.g., BEP-20) without using a bridge. Doing so may result in permanent loss.

Frequently Asked Questions (FAQ)
Q: Can I use the same MetaMask wallet for both Ethereum and BSC?
A: Yes! Your wallet address works across both chains, but balances and transactions are separate.
Q: Do I need BNB even if I’m not trading?
A: Yes — any action on BSC (sending tokens, connecting dApps, approving contracts) requires gas paid in BNB.
Q: Is adding Binance Smart Chain safe?
A: Yes, as long as you enter correct network details from trusted sources. Avoid copy-pasting from unverified websites.
Q: Can I add other EVM-compatible chains the same way?
A: Absolutely — this method works for Polygon, Avalanche, Fantom, and others.
Q: What happens if I send ETH to my wallet on BSC?
A: ETH cannot be sent directly to BSC. You must use a bridge (like the official Binance Bridge) to convert ERC-20 ETH into BEP-20 WETH.
Q: How do I remove a network from MetaMask?
A: Go to Settings > Networks > Connected Sites, find the network, and click "Delete."
Final Thoughts
Adding Binance Smart Chain to MetaMask is a simple yet transformative step for anyone exploring DeFi, NFTs, or Web3 applications beyond Ethereum. With lower fees, faster speeds, and access to a vibrant ecosystem of dApps, BSC enhances both functionality and cost-efficiency.
Just remember: always double-check network settings, secure your seed phrase, and keep enough BNB for gas when active on-chain.
By mastering cross-chain navigation today, you position yourself at the forefront of the evolving decentralized web.
