Binance has established a strong reputation in the cryptocurrency ecosystem, not only as a trading platform but also as a provider of blockchain infrastructure. One of its key offerings is the Binance Smart Chain (BSC), a network that supports smart contracts and decentralized applications. BSC operates alongside Binance Chain and is designed to be compatible with the Ethereum Virtual Machine, allowing users to interact with a wide range of tokens and dApps.
This guide will walk you through the process of adding Binance Smart Chain to your MetaMask wallet. Once configured, you can seamlessly manage BEP-20 tokens, interact with BSC-based dApps, and execute transactions using BNB.
Understanding MetaMask and Binance Smart Chain
MetaMask is a widely-used browser extension and mobile wallet that enables users to securely manage cryptocurrencies and interact with decentralized applications. It serves as a bridge between your browser and the blockchain, eliminating the need to run a full node. While MetaMask is natively designed for the Ethereum ecosystem, its flexible architecture allows connections to other compatible networks like Binance Smart Chain.
Binance Smart Chain is a blockchain platform that supports smart contracts and decentralized applications. It operates in parallel with Binance Chain and is optimized for fast transactions and low fees. BSC is compatible with Ethereum-based tools and standards, making it accessible to developers and users already familiar with the Ethereum ecosystem.
Step-by-Step Guide to Adding BSC to MetaMask
Install and Set Up MetaMask
If you haven't already installed MetaMask, begin by adding the extension to your browser:
- Visit the official MetaMask website and click "Download Now."
- Choose your browser (e.g., Chrome) and follow the prompts to install the extension.
- Once installed, open MetaMask and select "Create a Wallet" if you are a new user. If you have an existing wallet, choose "Import Wallet" and enter your recovery phrase.
- Secure your wallet by noting down the secret recovery phrase and storing it in a safe location. Complete the verification process to finalize the setup.
Configure Network Settings
By default, MetaMask connects to the Ethereum network. To add Binance Smart Chain, you need to manually configure the network settings:
- Open MetaMask and click on the network selection dropdown (usually set to "Ethereum Mainnet").
- Scroll down and select "Add Network."
- You will be prompted to enter the network details. Depending on whether you want to use the mainnet or testnet, enter the following parameters:
For Mainnet:
- Network Name: Binance Smart Chain
- New RPC URL: https://bsc-dataseed.binance.org/
- Chain ID: 56
- Currency Symbol: BNB
- Block Explorer URL: https://bscscan.com
For Testnet:
- Network Name: Binance Smart Chain Testnet
- New RPC URL: https://data-seed-prebsc-1-s1.binance.org:8545/
- Chain ID: 97
- Currency Symbol: BNB
- Block Explorer URL: https://testnet.bscscan.com
- After entering the details, click "Save." Your MetaMask wallet will now display BNB as the default currency, confirming a successful connection to Binance Smart Chain.
Fund Your Wallet
To start transacting on BSC, you need to fund your wallet with BNB:
- Obtain BNB from a cryptocurrency exchange or transfer it from another wallet.
- Send the BNB to your MetaMask wallet address. Ensure you are on the Binance Smart Chain network when receiving or sending funds.
- To add custom BEP-20 tokens, click "Import Tokens" in MetaMask, paste the token contract address, and confirm the addition.
Switch Between Networks
MetaMask allows you to switch seamlessly between Ethereum and Binance Smart Chain:
- Click the network dropdown menu in MetaMask.
- Select "Ethereum Mainnet" or "Binance Smart Chain" depending on your intended activity.
- Always verify the network before executing transactions to avoid errors.

Frequently Asked Questions
Do I need a Binance Chain wallet to use Binance Smart Chain with MetaMask?
No, you do not need a separate Binance Chain wallet. MetaMask can be configured to support Binance Smart Chain directly, allowing you to manage BNB and BEP-20 tokens without additional software.
Can I use the same MetaMask wallet for Ethereum and Binance Smart Chain?
Yes, the same MetaMask wallet can be used for both networks. However, you must manually add Binance Smart Chain as a custom network and switch between networks depending on your intended activity.
Is it safe to connect MetaMask to Binance Smart Chain?
Yes, provided you use official links and correct network parameters. Always ensure you are on the genuine MetaMask website and double-check RPC URLs and chain IDs to avoid phishing scams.
What tokens can I manage on BSC via MetaMask?
You can manage any BEP-20 token on Binance Smart Chain. Popular examples include CAKE, BAKE, and other tokens issued on the BSC network.
How do I switch back to Ethereum after using BSC?
Open MetaMask, click the network dropdown, and select "Ethereum Mainnet." Your wallet will instantly reflect your Ethereum assets and allow interactions with Ethereum-based dApps.
Are there any transaction fees when using BSC?
Yes, but they are generally lower than Ethereum fees. Transactions on BSC require a small amount of BNB to pay for gas costs.
