As blockchain technology evolves, the ability to interact with multiple networks has become essential for crypto users. One of the most popular and efficient blockchains today is BNB Smart Chain (BSC)—known for its fast transaction speeds and low fees. For users leveraging MetaMask, one of the leading cryptocurrency wallets, integrating BSC unlocks access to a thriving ecosystem of decentralized applications (dApps), DeFi protocols, NFT marketplaces, and more.
This comprehensive guide walks you through everything you need to know about connecting BNB Smart Chain to MetaMask, including step-by-step instructions for desktop and mobile, adding BEP-20 tokens, using the BSC testnet, and funding your wallet—all while ensuring security and compatibility.
Why Use BNB Smart Chain?
Before diving into setup steps, it’s important to understand why BNB Smart Chain has gained such widespread adoption:
- Low Transaction Fees: Compared to Ethereum, BSC offers significantly cheaper gas fees, making micro-transactions and frequent trades more affordable.
- High Performance: With a 3-second block time, transactions are confirmed quickly.
- EVM Compatibility: BSC supports Ethereum Virtual Machine (EVM) tools, meaning Ethereum-based dApps can be easily ported over.
- Thriving Ecosystem: From PancakeSwap to BakerySwap, BSC hosts hundreds of DeFi platforms, gaming apps, and NFT projects.
- Developer-Friendly: Strong documentation, grants, and community support make BSC ideal for building and testing new blockchain applications.

How to Add BNB Smart Chain to MetaMask
Adding BSC to your MetaMask wallet is simple and can be done either automatically or manually. Below are detailed methods for both desktop and mobile users.
Method 1: Automatically Add BSC via BscScan
The easiest way to add BNB Smart Chain is through BscScan, the official block explorer for BSC.
- Visit BscScan.com.
- Scroll to the bottom of the homepage and click the "Add BSC Network" button (it features a MetaMask icon).
- Your MetaMask extension will prompt you to approve adding the network.
- Confirm the request—MetaMask will auto-fill all required fields.
- Once added, switch your network from Ethereum to BNB Smart Chain.
This one-click method eliminates manual input errors and ensures accuracy.
Method 2: Manually Add BSC to MetaMask (Desktop)
If you prefer full control or the automatic method fails, follow these steps:
- Open your MetaMask browser extension.
- Click the current network (e.g., "Ethereum Mainnet") at the top.
- Select "Add Network" > "Add a network manually".
Enter the following details:
- 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".
MetaMask will now display BNB Smart Chain as an available network. Switch to it anytime with a single click.
Method 3: Add BSC to MetaMask Mobile App
The process on mobile mirrors the desktop version:
- Open the MetaMask mobile app.
- Tap the network dropdown at the top (e.g., "Ethereum").
- Tap "Add Network".
- Search for "BNB Chain" in the list and tap "Add".
Alternatively, choose "Custom Networks" and enter the same details as above.
Once saved, you can seamlessly switch between Ethereum, BSC, and other connected chains.
Add BSC Testnet to MetaMask for Developers
For developers testing dApps or smart contracts, connecting to the BSC Testnet is crucial.
Follow these steps:
- In MetaMask, go to Networks > Add Network > Add a network manually.
Input the following testnet parameters:
- Network Name: BNB 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
- Save the network.
To get free test BNB (tBNB), visit the BSC Testnet Faucet and connect your wallet.
How to Add BEP-20 Tokens to MetaMask
After setting up BSC, you may want to import custom BEP-20 tokens—the standard token type on BSC (similar to ERC-20 on Ethereum).
Here’s how:
- Ensure your network is set to BNB Smart Chain.
- Scroll down in MetaMask and click "Import Tokens".
- Paste the token’s contract address (found on BscScan or CoinGecko).
- The token symbol and decimals should auto-populate.
- Click "Next" > "Import Tokens".
Your BEP-20 token will now appear in your wallet balance.
💡 Pro Tip: You can also use sites like CoinMarketCap or CoinGecko—many include a “Add to MetaMask” button that auto-imports tokens with one click.

Frequently Asked Questions (FAQ)
Q: Is BNB Smart Chain the same as Binance Chain?
A: No. While both are part of the BNB ecosystem, BNB Smart Chain (BSC) supports smart contracts and dApps, whereas the original Binance Chain was designed primarily for fast trading via its decentralized exchange (DEX).
Q: Can I lose funds if I send ERC-20 tokens directly to my BSC address?
A: Yes—only send tokens that are bridged or natively supported on BSC. Always use the BNB Chain Bridge or a compatible exchange when moving assets between chains.
Q: Why is my transaction failing on BSC?
A: Most failures occur due to insufficient BNB for gas fees. Ensure you have a small amount of BNB in your wallet to cover transaction costs—even when interacting with other BEP-20 tokens.
Q: Do I need a separate wallet for BSC?
A: No. MetaMask allows you to use the same wallet across multiple networks, including Ethereum, BSC, Polygon, and others—just switch networks within the app.
Q: Is adding BSC to MetaMask safe?
A: Yes—as long as you enter the correct RPC URLs and avoid phishing sites. Never share your seed phrase or private keys.
Funding Your MetaMask Wallet on BSC
To interact with dApps on BNB Smart Chain, you’ll need BNB for gas fees.
Here’s how to fund your wallet:
- Switch MetaMask to BNB Smart Chain.
- Copy your wallet address from the top of the interface.
- On a crypto exchange (like OKX or Binance), withdraw BNB using the BEP-20 (BSC) network.
- Paste your MetaMask address and confirm the transfer.
- Wait a few moments—the funds will appear in your wallet.
⚠️ Warning: Sending BEP-20 tokens via the wrong network (e.g., ERC-20 instead of BEP-20) can result in permanent loss.
Using the BNB Chain Bridge
The BNB Chain Bridge enables cross-chain transfers between networks like Ethereum, Polygon, and BSC.
Steps:
- Go to BNB Chain Bridge.
- Connect your MetaMask wallet.
- Select source and destination chains (e.g., Ethereum → BSC).
- Choose asset (e.g., USDT) and amount.
- Confirm transaction in MetaMask.
- Wait for completion—your asset will appear on the target chain.
This tool is essential for accessing liquidity across ecosystems.
👉 Bridge assets securely with advanced cross-chain tools.
