How to add BSC (Binance Smart Chain) to MetaMask?

2025/07/09 16:50

What is BSC (Binance Smart Chain)?

Binance Smart Chain (BSC) is a blockchain network developed by Binance, designed to enable smart contract functionality and support decentralized applications (dApps). It runs in parallel with the Binance Chain, which focuses on fast and secure cryptocurrency transactions. BSC allows developers to build decentralized finance (DeFi) applications, NFT marketplaces, and other blockchain-based services that can interact with the Binance ecosystem.

For users who wish to interact with dApps built on BSC, such as PancakeSwap or BakerySwap, it's essential to have access to this network through a compatible wallet. MetaMask, one of the most popular Ethereum-based wallets, supports multiple networks, including BSC. Adding BSC to MetaMask enables users to send, receive, and manage BEP-20 tokens and interact with BSC-based platforms seamlessly.

Why Add BSC to MetaMask?

Adding BSC to MetaMask opens up a wide range of opportunities for crypto enthusiasts. Users can participate in yield farming, stake tokens, trade on decentralized exchanges, and even mint or buy NFTs on BSC-compatible platforms. Since MetaMask is non-custodial and easy to use, integrating BSC into the wallet simplifies access to these functionalities without needing a separate wallet like Trust Wallet.

Additionally, many projects deploy their tokens and smart contracts on BSC due to its lower transaction fees compared to Ethereum. By adding BSC to MetaMask, users can save on gas costs while still enjoying the security and flexibility of a trusted wallet interface.

How to Access the Network Settings in MetaMask

Before adding a new network, you must navigate to the correct settings within your MetaMask wallet. If you're using the browser extension version:

• Click on the MetaMask icon in your browser toolbar
• Unlock your wallet if prompted
• In the top-right corner, locate the network dropdown menu
• Scroll to the bottom and click on "Custom RPC" or look for an option labeled "Add Network"

This will open a form where you can input the necessary details for connecting to the Binance Smart Chain. Make sure you are not currently connected to any testnet or unknown network when making these changes.

Required Parameters to Add BSC

To successfully add BSC to MetaMask, you need to enter specific parameters correctly. Any mistake in these fields could result in failed transactions or inability to interact with the network. Below are the required fields and their corresponding values:

• Network Name: Binance Smart Chain Mainnet
• New RPC URL: https://bsc-dataseed.binance.org/
• ChainID: 56
• Currency Symbol: BNB
• Block Explorer URL: https://bscscan.com/

Each of these fields plays a crucial role in establishing a connection between MetaMask and the BSC network. The RPC URL serves as the communication bridge between your wallet and the blockchain. The ChainID ensures that MetaMask recognizes the correct chain and prevents accidental transactions on incompatible networks. The currency symbol helps identify balances within the wallet, and the block explorer URL allows you to view transactions directly from MetaMask.

Step-by-Step Instructions to Add BSC

Follow these steps carefully to ensure a successful configuration:

• Open MetaMask and click on the network selection at the top
• Select "Add Network" or "Custom RPC" depending on your MetaMask version
• Fill in the fields with the exact values provided earlier
• Double-check each entry to avoid typos
• Click "Save" or "Add Network" to confirm

Once added, the selected network should appear in your network dropdown. You can now switch to Binance Smart Chain Mainnet whenever you need to interact with dApps or transfer BEP-20 tokens.

Transferring BNB or BEP-20 Tokens After Adding BSC

After successfully adding BSC to MetaMask, you can begin transferring BNB or BEP-20 tokens to your wallet. To receive funds:

• Switch to Binance Smart Chain Mainnet in MetaMask
• Click on the "Account" section
• Copy your wallet address

When sending BNB or BEP-20 tokens from another wallet or exchange, make sure to select BSC (BNB) or Binance Smart Chain as the network. Sending funds via the wrong network (e.g., Ethereum or Binance Chain) may result in permanent loss of assets.

If you're withdrawing from Binance, for example:

• Choose BSC (BNB) under the network options
• Paste your MetaMask wallet address
• Confirm the transaction

It usually takes a few seconds to a couple of minutes for the transaction to be confirmed on the BSC blockchain.

Frequently Asked Questions (FAQ)

Q: Can I add BSC testnet to MetaMask?

Yes, you can add the BSC testnet by using different RPC URLs and ChainID. For testnet, the ChainID is 97 and the RPC URL is https://data-seed-prebsc-1-s1.binance.org:8443/. This is useful for developers testing dApps before deploying them on the mainnet.

Q: What happens if I send ETH to my BSC address in MetaMask?

Sending ETH to a BSC address will result in the loss of those funds because BSC and Ethereum are separate blockchains. Always ensure the correct network is selected before initiating a transfer.

Q: Do I need BNB to pay for gas fees on BSC?

Yes, just like ETH is used for gas on Ethereum, BNB is required to pay for transaction fees on BSC. Ensure you have a small amount of BNB in your MetaMask wallet to execute transfers or interact with dApps.

Q: Is it safe to use MetaMask with BSC?

Yes, as long as you follow best practices like keeping your seed phrase secure and double-checking network settings, using MetaMask with BSC is safe. Always verify addresses and network selections before sending funds.
