Binance Smart Chain MetaMask: How to Add BNB Chain and Use It Safely
Use MetaMask with BNB Smart Chain (BSC) to hold tokens, sign transactions, and use BSC dapps—after adding the network.
What “Binance Smart Chain MetaMask” means
“Binance Smart Chain MetaMask” means using the MetaMask wallet to connect to BNB Smart Chain (BSC) so you can hold tokens, sign transactions, and use BSC dapps with the same wallet interface you use on Ethereum.
BNB Smart Chain is the current name for what older guides call Binance Smart Chain. MetaMask is a multi-network EVM wallet, so it can switch between Ethereum and BNB Smart Chain once you add the network.
What you need before you add BNB Smart Chain to MetaMask
You need MetaMask, a safe backup of your recovery phrase, and the correct BNB Smart Chain network settings.
- MetaMask installed (browser extension or mobile app)
- Secret Recovery Phrase backed up offline (never saved in screenshots, cloud notes, or email)
- A small amount of BNB for gas on BNB Smart Chain
- Network settings (RPC URL, Chain ID, and explorer), either from a trusted list or entered manually

How to add BNB Smart Chain to MetaMask (recommended methods)
Adding BNB Smart Chain to MetaMask is done by creating a network entry with the correct Chain ID and RPC endpoint, then switching to that network.
Method 1: Add the network from a trusted chain list
A trusted chain list reduces typos, but you still need to review what gets added.
- Open MetaMask and unlock it.
- Go to a reputable chain list (for example, Chainlist) and search for BNB Smart Chain.
- Select the network entry, then choose Add to MetaMask.
- Review the details in the MetaMask pop-up, then confirm.
Cancel if any field looks wrong, then use the manual method below.
Method 2: Add the network manually (mainnet)
Manual setup is best when you want to verify each field yourself.
- In MetaMask, open the network selector at the top.
- Choose Add network, then select Add a network manually (wording varies).
- Enter the BNB Smart Chain (Mainnet) values below, then save.
- Switch your active network to BNB Smart Chain.
BNB Smart Chain (Mainnet) network settings (verify current values before saving):
- Network Name: BNB Smart Chain
- New RPC URL (examples):
- Chain ID: 56
- Currency Symbol: BNB
- Block Explorer URL: https://bscscan.com
Safety tip: treat unsolicited “custom RPC” URLs sent via DMs as suspicious. An untrusted RPC can mislead you about what you are signing or where a transaction was broadcast.
Optional: Add BNB Smart Chain Testnet to MetaMask
BNB Smart Chain testnet is a separate network used for testing, and it will not show your mainnet funds.
- Open MetaMask’s Add network flow again.
- Add a new network using the testnet values below.
- Switch to the testnet only when you are intentionally testing.
BNB Smart Chain (Testnet) network settings (verify current values before saving):
- Network Name: BNB Smart Chain Testnet
- New RPC URL (example): https://data-seed-prebsc-1-s1.binance.org:8545/
- Chain ID: 97
- Currency Symbol: tBNB
- Block Explorer URL: https://testnet.bscscan.com
Keep testnet and mainnet clearly separated in your own notes to avoid sending funds to the wrong chain.
How to use BNB Smart Chain with MetaMask
Using BNB Smart Chain in MetaMask is a four-part process: switch networks, add BNB for gas, connect to a dapp, then confirm transactions.
Step 1: Switch MetaMask to BNB Smart Chain
Switching networks is the action that tells MetaMask which chain to query and where to broadcast transactions.
- Open the network selector in MetaMask.
- Choose BNB Smart Chain (not Ethereum, not a testnet).
Step 2: Fund your MetaMask address with BNB for gas
BNB is required to pay gas on BNB Smart Chain, even when you are swapping or moving other tokens.
- Copy your MetaMask public address.
- Send BNB to that address from an exchange or another wallet.
- Select BNB Smart Chain (BEP-20) as the withdrawal network if you want the funds on BSC.
- Confirm arrival by searching your address on BscScan.
Wrong network quick triage (fast checks before you panic):
- Look up your address on the relevant explorer (BscScan for BSC, Etherscan for Ethereum).
- Switch MetaMask to the network where the explorer shows the funds.
- If it is a token, import it using the token contract address on that network.
- Confirm the sending platform’s withdrawal network (BEP-20 vs ERC-20) from the receipt.
Wrong-network transfers are often recoverable, but steps depend on where they were sent. Reference: how to fix a crypto transfer sent on the wrong network.
Step 3: Connect to a BSC dapp and approve the connection
A dapp connection only shares your public address, but it sets up future transaction prompts.
- Open the dapp site and click Connect Wallet.
- Select MetaMask, then approve the connection request.
- Confirm the network indicator in the dapp shows BNB Smart Chain.
A good habit is to check the URL again right before you approve the connection request.
Step 4: Swap, stake, or interact with smart contracts
Every on-chain action creates a MetaMask confirmation screen, and that screen is your last line of defense.
- Confirm the network is BNB Smart Chain.
- Review the recipient address and the amount.
- Read any contract warning text, especially for token approvals.
- Keep enough BNB available for gas, or the transaction will fail.
Safer approvals: see how token approvals work and how to revoke them.
Common network settings and what they do
MetaMask network fields determine how MetaMask talks to the chain and what explorers you use to verify activity.
- RPC URL: The node endpoint MetaMask uses to read balances, fetch nonces, and broadcast transactions.
- Chain ID: The network identifier embedded in signatures so transactions cannot be replayed on a different chain (BSC mainnet is 56).
- Currency symbol: The display label for gas (BNB on BSC).
- Block explorer URL: The explorer MetaMask links to for transaction and address views (BscScan for BSC).
If you see unexpected balances or missing transactions, the RPC URL is often the first thing to sanity-check.
Benefits and drawbacks of using BNB Smart Chain in MetaMask
BNB Smart Chain in MetaMask is appealing for cost and familiarity, but it comes with different risk patterns than Ethereum.
Benefits
- Fees are often lower for common actions like swaps and transfers, especially compared with Ethereum mainnet during peak demand.
- EVM compatibility means many Ethereum-style dapps and tokens have BSC versions.
- One wallet UI: you can manage Ethereum and BNB Smart Chain from the same MetaMask interface by switching networks.
Drawbacks
- Higher scam risk in some areas, including fake tokens, copycat sites, and misleading airdrops.
- RPC issues can look like wallet problems, such as balances not loading or transactions failing to broadcast.
- Bridge and cross-chain risk increases if you move assets between Ethereum and BSC using third-party bridges.
Moving assets across chains adds bridge risk. Read a beginner-to-intermediate guide to crypto bridges before you transfer more than you can afford to lose.
BNB Smart Chain vs Ethereum in MetaMask (side-by-side)
BNB Smart Chain and Ethereum both work inside MetaMask, but they differ in gas token, fee profile, and ecosystem maturity.
| Category | BNB Smart Chain (BSC) | Ethereum Mainnet |
|---|---|---|
| Gas token | BNB | ETH |
| Chain ID | 56 | 1 |
| Typical fees | Often lower | Often higher |
| App compatibility | EVM dapps, many forks and clones | EVM dapps, more established DeFi base layer |
| Common risk patterns | Fake tokens, risky approvals, spoof sites | Phishing, high-fee mistakes, complex transaction ordering |
| Explorer | BscScan | Etherscan |
Takeaway: choose BNB Smart Chain when low fees and BSC-native apps matter; choose Ethereum when you need Ethereum-native protocols, deeper liquidity, or assets that primarily live on mainnet.
How to troubleshoot common Binance Smart Chain MetaMask issues
Most MetaMask problems on BSC come from four causes: you are on the wrong network, you have no BNB for gas, your RPC endpoint is acting up, or the token is not imported.
Pending transaction that will not confirm
A stuck transaction is commonly an RPC display issue or a nonce issue, and the explorer view tells you which one it is.
- First check BscScan: open the transaction hash.
- Not found on BscScan: your wallet likely did not broadcast it. Try switching to another RPC and refresh MetaMask.
- Found and pending: it is on-chain and waiting. Consider speeding it up in MetaMask, or replacing it using the same nonce (advanced).
Example scenario: you confirm a swap, MetaMask shows “Pending” for 20 minutes, and BscScan shows no record. That usually points to the RPC endpoint, not the chain.
Tokens not showing in MetaMask
Tokens often need to be imported manually on BNB Smart Chain.
- Open BscScan and search your address to confirm the token balance exists on-chain.
- In MetaMask, choose Import tokens.
- Paste the token’s contract address from BscScan and add it.
Skip “token lists” sent by strangers. Import the contract address only after verifying it on the explorer.
Funds “missing” after a transfer
Funds are usually on a different network than the one you are viewing.
- Check your address on BscScan and Etherscan.
- Identify the network used for the transfer (BEP-20 for BSC, ERC-20 for Ethereum).
- Switch MetaMask to that network and re-check.
“Wrong network” message in a dapp
A dapp shows “wrong network” when it expects BNB Smart Chain but your wallet is set to something else.
- Switch MetaMask to BNB Smart Chain.
- Refresh the page.
- Disconnect and reconnect the wallet if the dapp still shows the old network.
Gas estimation failed
Gas estimation fails when a contract call is likely to revert, the token has restrictions, or your RPC is unstable.
- Verify the token and contract activity on BscScan (recent swaps, holders, and contract verification help).
- Try another RPC endpoint and repeat the action.
- Test with a smaller amount to confirm whether the failure is size-related or contract-related.
Safety checklist for using BNB Smart Chain with MetaMask
Safer BNB Smart Chain usage in MetaMask comes down to careful site access, careful approvals, and separating risk.
- Bookmark the dapps you use and open them from bookmarks, not ads.
- Verify the domain before you connect a wallet.
- Confirm token contract addresses on BscScan before you import anything.
- Limit token approvals when the dapp allows it, and revoke old approvals.
- Separate wallets: one for long-term holdings, one for higher-risk dapps.
- Protect your Secret Recovery Phrase and never share it with anyone.

FAQ
How do I add Binance Smart Chain to MetaMask?
You add Binance Smart Chain to MetaMask by adding the BNB Smart Chain network in MetaMask, either via a trusted chain list or by entering the mainnet settings (Chain ID 56, BscScan explorer, and a valid RPC URL), then switching to that network.
What RPC should I use for BNB Smart Chain in MetaMask?
A common mainnet RPC example is https://bsc-dataseed.binance.org/, and you can also use other official dataseed endpoints, but you should verify current RPC values from BNB Chain sources before saving them.
Can I add BNB Smart Chain testnet to MetaMask?
Yes, you can add BNB Smart Chain testnet by creating a separate MetaMask network entry (commonly Chain ID 97 with the testnet BscScan explorer) and switching to it only for testing.
What network do I choose to send BNB to MetaMask?
Choose BNB Smart Chain (BEP-20) if you want BNB on BSC for BSC gas fees, and choose Ethereum (ERC-20) only if you intend to use BNB on Ethereum and pay ETH gas there.
Why is my BSC token not showing in MetaMask?
A BSC token may not show because MetaMask has not imported it, so you need to add the token using the correct BNB Smart Chain contract address and confirm the balance on BscScan first.
Can I use the same MetaMask address on Ethereum and BNB Smart Chain?
Yes, the same MetaMask address works on both networks, but assets exist per network, so you must switch MetaMask networks to see and use the right balances.
Next steps
Start with a small test transfer when moving assets between Ethereum and BNB Smart Chain, and verify every step on the explorer before you repeat it at a larger size. Keep your own short list of trusted dapps, your preferred BSC RPC endpoint, and a recurring reminder to review and revoke old approvals.
