Adding Binance Smart Chain to MetaMask
MetaMask is a free web and mobile crypto wallet with over ten million active monthly users. MetaMask was launched in 2016 to provide support for the Ethereum network, allowing users to store and swap cryptocurrencies, host a rich suite of decentralized applications like yield farming protocols and NFT marketplaces, token swap applications, and play blockchain-based games.Â
Binance Smart Chain (BSC), rebranded as BNB Chain in 2022, has gained traction as an Ethereum alternative due to the low transaction costs and high speeds. BSC is equipped with Ethereum Virtual Machine (EVM) and smart contracts to support non-fungible tokens (NFTs) and Ethereum applications.
With the MetaMask wallet, you can switch freely between your Ethereum and Binance crypto wallets, access DApps operating on both ecosystems, and trade on DEXs from either network.

How to Integrate Binance Smart Chain With MetaMask?
Follow our step-by-step guide for connecting MetaMask to Binance Smart Chain:
Step #1: Install MetaMask Wallet
If you don’t have a wallet, the first step is downloading and installing MetaMask, which is available as a browser extension for Chrome, Firefox, Brave and Edge and as a mobile app for Android and iOS. For this article, we’ll focus on MetaMask’s browser version for Chrome.
- Launch Chrome, then navigate to the official Metamask website and click on the “Download” button in the top right corner.
- Navigate to the “Install MetaMask for Chrome” button at the bottom of the download page.
- After installation, you’ll be asked whether you’re “New to MetaMask.”
- If this is your first time using MetaMask, select “Create a Wallet” or select “Import Wallet” for your secret recovery phrase.
- To create a wallet, you must create a password and write down your backup seed phrase somewhere secure (preferably not on an Internet-connected device). This phrase will help recover your funds if your device is damaged or lost.
Step #2: Sign In to MetaMask
You can access your freshly installed MetaMask wallet (MM) by clicking the three dots in the screen’s upper-right corner.
To open MetaMask on an extended screen, click on the “Expand View.”
You’ll then be redirected to your wallet in a new tab.
Step #3: Configure the Wallet
You might notice straight away that we’re still working with an Ethereum wallet. At best, this won’t function with Binance Smart Chain DApps, and at worst, you can lose funds by sending them to invalid addresses.
Let’s fix it. We must go to the Settings page to route the wallet toward Binance Smart Chain nodes.
Select settings from the dropdown menu, then go to the “Networks” menu.
Click on the “Add Network” in the top-right corner to manually add the Binance Smart Chain.
You’ll be redirected to a new screen to add the technical information needed to connect MetaMask to the Binance Chain network. You can choose between the two networks – the testnet or the mainnet; the parameters of each can be found below:
Click “Add Network,” enter the required information, and click “save”:
Binance Smart Chain Mainnet
​​Network Name: Smart Chain
New RPC URL: https://bsc-dataseed.binance.org/
ChainID: 56
Currency Symbol: BNB
Block Explorer URL: https://bscscan.com
Testnet
Network Name: Smart Chain – Testnet
New RPC URL: https://data-seed-prebsc-1-s1.binance.org:8545/
ChainID: 97
Symbol: BNB
Block Explorer URL: https://testnet.bscscan.com
After entering the network information, you’ll be redirected to the wallet screen. The two red boxes in the screenshot below prove that the Binance Smart Chain has been successfully added to your MetaMask wallet. The first box indicates the BNB token standard, while the bottom right says “Smart Chain was successfully added.”
Step #4: Transfer BNB to Your MetaMask Wallet
After successfully configuring the BSC network on your MetaMask wallet, you can easily transfer BNB between other Binance wallets (including your Binance exchange account or the Binance Chain wallet) and the MetaMask wallet. Simply go to your exchange, pick “Withdraw crypto” from your wallet, and select BNB as your coin.
To transfer BNB coins, you must first copy your MetaMask wallet address. Simply click on your account address (in MetaMask), and it will be copied to your clipboard.
Head back to the Binance page and paste your wallet address. Binance will most likely automatically select the network over which the BNB can be sent. And as you can see, in this example, it has already selected the BEP-20 network.
Remember that you must only select the BSC network; otherwise, your assets will be lost!
Now, input the amount to be transferred and click “Withdraw.” You must accept the agreement, warning you that your digital assets will be lost if you choose the wrong network. Ensure that you’ve selected the BSC network.
Your transaction will be finalized, and you must wait for the network to process it.
Frequently Asked Questions
Is Binance Smart Chain Compatible With MetaMask?
MetaMask is mainly used to interact with the Ethereum blockchain, but you can also link it to the Binance Smart Chain to make BNB transactions using MetaMask. Additionally, BNB can be exchanged for other tokens on decentralized exchanges.
Is the Binance Smart Chain BEP20?
Binance Smart Chain has a BEP20 token standard that functions similarly to Ethereum’s ERC20 standard in many aspects. All tokens produced on BSC must adhere to the BEP20 standard.
Which Is Better, ERC20 or BEP20?
BEP20 coins are subject to higher standards than ERC20 tokens and have lower transaction fees. BEP20 coins allow for speedier transactions, while ERC20 tokens are more secure.
