Adding Binance Smart Chain to MetaMask

·

Integrating Binance Smart Chain (BSC) with MetaMask is a straightforward process that unlocks access to a high-speed, low-cost blockchain ecosystem. Originally designed for Ethereum, MetaMask supports multiple EVM-compatible networks—including BSC—making it one of the most versatile crypto wallets available today. By adding Binance Smart Chain (now rebranded as BNB Chain), users can interact with decentralized applications (DApps), trade tokens on decentralized exchanges (DEXs), and manage BEP-20 assets directly from their MetaMask wallet.

This guide walks you through each step of connecting MetaMask to Binance Smart Chain, ensuring secure and seamless cross-chain functionality.

Why Connect Binance Smart Chain to MetaMask?

Binance Smart Chain offers faster transaction speeds and significantly lower fees compared to Ethereum. It’s fully compatible with the Ethereum Virtual Machine (EVM), meaning Ethereum-based tools like MetaMask can easily integrate with it. This compatibility allows developers and users to deploy or use DApps across both chains without rebuilding infrastructure.

With MetaMask configured for BSC, you gain access to:

Step-by-Step Guide: Adding Binance Smart Chain to MetaMask

Step 1: Install the MetaMask Extension

To begin, install MetaMask as a browser extension. It’s supported on Chrome, Firefox, Brave, and Edge, and also available as a mobile app for iOS and Android. For this tutorial, we’ll use the Chrome desktop version.

  1. Open Google Chrome and go to the official MetaMask website.
  2. Click "Download" in the top-right corner.
  3. Select "Install MetaMask for Chrome".
  4. Confirm the installation in the Chrome Web Store.

After installation, click the puzzle icon in Chrome’s toolbar, pin MetaMask for quick access, and launch it.

If you're new to MetaMask:

If you already have a wallet:

Step 2: Open Your MetaMask Wallet

Once installed:

  1. Click the fox icon in your browser toolbar to open MetaMask.
  2. Enter your password to unlock the wallet.
  3. To view more details, click the three dots in the top-right corner and select "Expand View".
  4. This opens your full wallet interface in a new tab.

You’ll notice that by default, MetaMask is connected to the Ethereum network. To use BSC, we need to manually add it.

Step 3: Add Binance Smart Chain Network

MetaMask doesn’t include BSC by default, so you must add it manually using specific network parameters.

  1. In the expanded view, click your network dropdown (e.g., "Ethereum Mainnet").
  2. Select "Add Network" → "Add a Network Manually".
  3. Enter the following details for the BSC Mainnet:

Click "Save" to confirm.

💡 Tip: Always double-check these values. Entering incorrect details may result in lost funds.

After saving, MetaMask will switch to the "Smart Chain" network, confirming successful integration.

For testing purposes, you can also add the BSC Testnet:

Step 4: Transfer BNB to Your MetaMask Wallet

To interact with BSC-based DApps or pay transaction fees (gas), you’ll need BNB in your wallet.

Here’s how to send BNB from an exchange like Binance:

  1. Copy your MetaMask wallet address by clicking on the address in the top-left corner.
  2. Log into your Binance account.
  3. Go to Wallet → Spot → Withdraw.
  4. Select BNB as the withdrawal asset.
  5. Paste your MetaMask address.
  6. Choose the BEP-20 (BSC) network—never use BEP2 or ERC20 unless sending to another chain.
  7. Enter the amount and confirm the transaction.

Wait a few minutes for confirmation. Once received, your BNB balance will appear in MetaMask under the Smart Chain network.

Frequently Asked Questions

Q: Is Binance Smart Chain compatible with MetaMask?
Yes, Binance Smart Chain (BNB Chain) is fully compatible with MetaMask because it uses the Ethereum Virtual Machine (EVM). You can connect it manually using custom RPC settings.

Q: What is the difference between BEP20 and ERC20?
BEP20 is Binance Smart Chain’s token standard, similar to Ethereum’s ERC20. BEP20 tokens typically have lower transaction fees and faster processing times but may offer slightly less decentralization than ERC20.

Q: Can I lose my funds if I send them to the wrong network?
Yes—sending tokens via the wrong network (e.g., withdrawing ERC20 tokens to a BEP20 address) can result in permanent loss. Always verify the network before confirming any transaction.

Q: Do I need BNB in my wallet to use BSC?
Yes, you need BNB to pay gas fees when interacting with DApps or transferring tokens on BSC.

Q: Can I switch back to Ethereum after adding BSC?
Absolutely. Use the network dropdown in MetaMask to toggle between Ethereum Mainnet, Smart Chain, and any other added networks.

Q: Is there a fee to add BSC to MetaMask?
No, adding a network is free. You only pay gas fees when making transactions on-chain.

Adding Binance Smart Chain to MetaMask expands your access to decentralized finance (DeFi), NFTs, and gaming platforms with minimal cost and maximum flexibility. With proper configuration and security practices, you can safely navigate both Ethereum and BSC ecosystems using a single wallet interface.
