Connecting your MetaMask wallet to BNB Smart Chain (BSC) opens the door to a fast, low-cost ecosystem of decentralized applications (dApps), yield farming platforms, and token swaps. Originally built for Ethereum, MetaMask now supports multiple blockchains — including BSC — making it one of the most versatile Web3 wallets available today.
Whether you're using the MetaMask browser extension or mobile app, the process is simple and takes just a few minutes. This guide walks you through every step — from setting up your wallet to adding both the BSC mainnet and testnet, sending test tokens, and understanding cross-chain limitations.
Why Connect MetaMask to BNB Smart Chain?
BNB Smart Chain offers high-speed transactions with minimal fees compared to Ethereum, especially during peak network congestion. By connecting MetaMask to BSC, you gain access to:
- Thousands of dApps in the BNB ecosystem
- Lower gas fees when swapping or staking tokens
- Faster transaction confirmations
- Interoperability with Binance’s broader infrastructure

Setting Up Your MetaMask Wallet
Before connecting to BNB Smart Chain, ensure you have MetaMask installed:
- Visit the official MetaMask download page and install the extension for Chrome, Firefox, Brave, or use the iOS/Android app.
- Click "Create a Wallet" and follow the setup instructions.
- Secure your wallet by writing down your Secret Recovery Phrase (also known as a seed phrase). This acts as the master key to your funds.
- Store this phrase securely — never share it with anyone.
- Re-enter the recovery phrase to confirm it's correctly saved.
- Once confirmed, your wallet is ready for use.
Your wallet will default to the Ethereum Mainnet. To interact with BSC-based dApps, you’ll need to add the BNB Smart Chain network manually.
How to Add BNB Smart Chain Mainnet to MetaMask
Follow these steps to connect MetaMask to the BSC mainnet:
- In MetaMask, click the network dropdown (top-left, usually showing "Ethereum Mainnet").
- Select "Add Network".
- Search for BNB Chain in the list and click "Add".
Review the network 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 "Confirm" to save.
You’ll now see BNB Smart Chain listed in your network options. Click "Switch to BNB Chain" to begin using it.
Important: Assets on one blockchain (e.g., Ethereum) cannot be directly transferred to another (e.g., BSC). To move funds between chains, you must use a trusted blockchain bridge.
To pay transaction fees on BSC, you’ll need BNB in your wallet — specifically in the BEP-20 format. You can transfer BNB from an exchange like Binance to your MetaMask address via the BEP-20 network.

Adding BNB Smart Chain Testnet for Practice
The BNB Smart Chain Testnet lets you experiment with transactions using free test tokens (tBNB), which have no real monetary value. It's perfect for learning how wallets and dApps work without risking funds.
To add the testnet:
- In MetaMask, go to Settings > Networks > Add Network.
- Choose "Add a Network Manually".
Enter the following 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
- Click "Save" — the network will now appear in your list.
Testing Transactions on BSC Testnet
Now that you’re connected to the testnet, let’s simulate a transaction:
- Copy your MetaMask wallet address by clicking on it.
- Visit the BNB Smart Chain Faucet.
- Paste your address into the field and click "Give me BNB" > "0.1 tBNB".
- Wait a few seconds for 0.1 tBNB to appear in your wallet.
Once received:
- Click "Send" in MetaMask.
- Paste any valid BSC testnet address (you can find sample addresses on BscScan Testnet).
- Enter an amount (e.g., 0.05 tBNB) and proceed.
- Confirm the transaction details and click "Confirm".
After a few seconds, the transaction will be processed. You can view it under the Activity tab in MetaMask or track it on the BscScan testnet explorer.
This hands-on experience helps build confidence before handling real assets.
Frequently Asked Questions
Can I use the same MetaMask wallet for both Ethereum and BNB Smart Chain?
Yes. Your MetaMask wallet uses the same private keys across all blockchains. Switching between Ethereum and BSC doesn’t require creating a new wallet — just change the active network.
Do I need BNB to make transactions on BSC?
Yes. Like Ethereum requires ETH for gas, BSC requires BNB (in BEP-20 format) to cover transaction fees.
What happens if I send ERC-20 tokens to a BEP-20 address?
Sending tokens to the wrong chain can result in permanent loss of funds. Always double-check the network and token standard before confirming any transfer.
Is there a difference between BNB Chain and BNB Smart Chain?
BNB Smart Chain is part of the larger BNB Chain ecosystem, which also includes the BNB Beacon Chain. When people refer to interacting with dApps or using MetaMask, they typically mean BNB Smart Chain (BSC).
How do I switch back to Ethereum after using BSC?
Simply open MetaMask, click the current network name (e.g., "BNB Smart Chain"), and select "Ethereum Mainnet" from the dropdown menu.
Can I lose my funds while adding a new network?
No. Simply adding a network doesn’t risk your funds. The danger lies in sending assets to incompatible networks or revealing your seed phrase.
Final Thoughts
MetaMask remains one of the most user-friendly gateways into Web3, supporting not only Ethereum but also powerful alternatives like BNB Smart Chain. With just a few clicks, you can unlock access to a thriving ecosystem of DeFi protocols, NFT markets, and gaming platforms — all while maintaining full control over your digital assets.
By following this guide, you’ve learned how to securely set up MetaMask, connect it to both mainnet and testnet versions of BSC, and safely test transactions using tBNB.
As blockchain technology evolves, being able to navigate multiple networks becomes increasingly valuable. Start exploring today — safely, confidently, and with clarity.
