The Binance Smart Chain (BSC) has become one of the most popular blockchain networks for decentralized applications (dApps), yield farming, and low-cost transactions. For users leveraging MetaMask as their primary wallet, accessing BSC-based dApps requires holding BNB — the native cryptocurrency that powers gas fees on the network.
However, many newcomers face confusion when trying to transfer or acquire BNB for use within MetaMask on the Binance Smart Chain. Since MetaMask defaults to the Ethereum Mainnet (ERC-20), switching to BEP-20 — BSC’s token standard — requires careful setup and understanding of cross-chain mechanics.
This guide walks you through the complete process of adding Binance Smart Chain to MetaMask, acquiring BNB from fiat currency, and safely withdrawing funds back to fiat — all while minimizing fees and avoiding common pitfalls.
Add the Binance Smart Chain Network to MetaMask
Before you can interact with BSC-based tokens or dApps, you must first configure MetaMask to support the Binance Smart Chain.
Here's how:
- Open MetaMask and navigate to Settings > Networks > Add Network.
Enter the following details:
- 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
- Click Save.
Once added, you can switch between Ethereum and Binance Smart Chain directly from the network dropdown in MetaMask.

How to Convert Fiat to BNB for Use on Binance Smart Chain
There are several pathways to convert traditional currency (fiat) into BNB on the Binance Smart Chain. Below are two reliable methods using regulated exchanges: Binance.us and Coinbase, each suited for different user preferences.
Method 1: Buy BNB Directly via Binance
The most efficient way to get BNB into MetaMask is purchasing it directly on a Binance exchange that supports BEP-20 withdrawals.
Steps:
- Create a Binance Account: Sign up at binance.us (U.S. users) or binance.com (international).
- Deposit Fiat: Add funds via bank transfer, debit card, or other supported methods.
- Buy BNB: Navigate to the trading interface and purchase BNB using USD or another available pair.
Withdraw via BEP-20 (BSC):
- Select “Withdraw” > Choose BNB
- Ensure the network is set to BEP20 (BSC) — never use ERC-20 or BEP2 here
- Paste your MetaMask wallet address (same format across networks)
- Confirm the transaction.
Your BNB should appear in MetaMask under the Binance Smart Chain network within 1–5 minutes.
⚠️ Always double-check the withdrawal network. Sending via ERC-20 will route through Ethereum, leading to potential loss if not recoverable.
Method 2: Bridge Funds from Coinbase (ERC-20 to BEP-20)
Coinbase does not support direct BEP-20 withdrawals, so bridging is required.
Steps:
- Buy USDT on Coinbase: Purchase USDT (ERC-20) using fiat.
- Send USDT to MetaMask: Transfer USDT to your MetaMask wallet under the Ethereum network.
- Switch to BSC in MetaMask: Ensure you’ve already added the Binance Smart Chain network.
Bridge USDT from Ethereum to BSC:
- Visit a trusted cross-chain bridge like app.multichain.org
- Connect MetaMask
Select:
- From: Ethereum (ERC-20 USDT)
- To: Binance Smart Chain (BEP-20 USDT)
- Approve and confirm the transaction
💡 Note: Bridging incurs two fees — approval and execution — often totaling $30+ due to high Ethereum gas costs. Consider this method only for larger transfers where fees are proportionally lower.
- Once received on BSC, use MetaMask’s built-in Swap feature to exchange USDT for BNB at competitive rates with minimal fees.

How to Withdraw BNB Back to Fiat
After interacting with dApps or earning rewards on BSC, you may want to cash out your BNB holdings.
Option 1: Sell via Binance
This is the simplest and most cost-effective route.
Steps:
- In your Binance account, go to Wallet > Spot > Deposit.
- Search for BNB and select BEP-20 (BSC) as the network.
- Copy the deposit address provided.
- In MetaMask, send your BNB (on BSC) to this address.
- Once credited, sell BNB for USD directly on Binance.
- Withdraw USD via ACH (for small amounts) or wire transfer (for larger sums).
Option 2: Cash Out via Coinbase (Using a Bridge)
If you prefer Coinbase for fiat off-ramping:
- In MetaMask (on BSC), swap BNB for USDT using the Swap function.
- Use a bridge (e.g., multichain.org) to move USDT from BEP-20 (BSC) back to ERC-20 (Ethereum).
- Send USDT from MetaMask (Ethereum network) to your Coinbase wallet.
- Convert USDT to USD and cash out via linked bank account.
🔍 Tip: This method involves higher fees and longer processing times. Only use it if you don’t have access to a BEP-20-compatible exchange.
Frequently Asked Questions (FAQ)
Q: Can I use the same MetaMask address for both Ethereum and BSC?
Yes. Your public wallet address remains identical across both networks. However, transactions must be sent via the correct network (ERC-20 vs BEP-20) to avoid fund loss.
Q: Why can’t I see my BNB after sending?
Ensure you’re viewing MetaMask on the Binance Smart Chain network, not Ethereum. If still missing, manually add the BNB token under "Import Tokens" using its contract address: 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c.
Q: Is it safe to use cross-chain bridges?
Reputable bridges like Multichain are widely used but come with risks including smart contract vulnerabilities and high fees. Always verify URLs and review transaction details before confirming.
Q: What’s the difference between BEP-2, BEP-20, and ERC-20?
- BEP-2: Native token standard on Binance Chain (not compatible with smart contracts)
- BEP-20: Smart contract-compatible standard on Binance Smart Chain
- ERC-20: Ethereum’s token standard
They are not interchangeable without a bridge or exchange conversion.
Q: How much does it cost to transfer BNB from BSC to MetaMask?
Gas fees on BSC are typically under $1 per transaction. The cost depends on network congestion but remains significantly cheaper than Ethereum.
Q: Can I lose my funds during this process?
Yes — common mistakes include selecting the wrong network, sending to incorrect addresses, or falling victim to phishing sites. Always double-check URLs, networks, and recipient addresses.
Final Thoughts
Getting BNB into MetaMask for use on the Binance Smart Chain doesn’t have to be complicated — especially when using direct purchase and withdrawal methods like those offered by Binance.
While bridging offers flexibility, it introduces complexity and higher costs due to Ethereum’s gas fees. For most users, buying BNB directly on a BEP-20-supporting exchange and withdrawing to MetaMask is faster, safer, and more economical.
As blockchain ecosystems continue evolving, understanding cross-network operations becomes essential for maximizing utility and minimizing risk.
