What Is MetaMask?
MetaMask is the world's most widely used Ethereum-compatible crypto wallet, with over 30 million monthly active users. Originally designed for Ethereum, its EVM (Ethereum Virtual Machine) compatibility means it works seamlessly with any EVM-compatible chain — including Binance Smart Chain (BSC). As a browser extension for Chrome, Firefox, Brave, and Edge, MetaMask integrates directly into your web browser, making it the preferred wallet for desktop DeFi users.
MetaMask is non-custodial — your private keys are stored locally in your browser, encrypted by your password. This means you, and only you, control your funds. No company, including MetaMask's developer ConsenSys, can access or freeze your assets.
For BSC users and BEP-20 token creators, MetaMask is an excellent choice because it provides deep integration with desktop dApps, supports hardware wallets for maximum security, and allows fine-grained control over gas settings. The only initial friction is that BSC isn't pre-configured — you need to add the network manually, which this guide walks you through completely.
Installing MetaMask (Chrome, Firefox, and Mobile)
MetaMask is available as a browser extension and a standalone mobile app. Here's how to install each version.
Browser Extension (Recommended for Desktop)
Visit metamask.io
Always download from the official website metamask.io or directly from your browser's extension store. Never search "MetaMask" on Google and click ads — sponsored results can lead to phishing clones.
Click "Download" and Add to Browser
Select your browser (Chrome, Firefox, Brave, or Edge). You'll be taken to the official extension store. Click "Add to Chrome" (or equivalent) and confirm the permissions dialog.
Pin the Extension
Click the puzzle piece icon in Chrome's toolbar and pin MetaMask for easy access. The fox icon will appear in your browser toolbar.
Create a New Wallet
Click the MetaMask icon, agree to the terms, and click "Create a new wallet." Set a strong password (this encrypts your local wallet data). MetaMask will then display your 12-word Secret Recovery Phrase.
Secure Your Secret Recovery Phrase
Write down all 12 words in exact order on paper. MetaMask will verify you've done this before proceeding. Store the paper securely — this phrase recovers your entire wallet on any device.
MetaMask Mobile (iOS & Android)
MetaMask also has a mobile app available on the App Store and Google Play. The setup process is nearly identical — download, create wallet, save seed phrase. The mobile app includes a built-in browser for dApp access. However, for BSC token creation and heavy DeFi activity, the desktop extension generally provides a better experience.
Security Warning: Your Secret Recovery Phrase (seed phrase) gives complete access to your wallet. Never type it into any website, share it via chat, or store it in screenshots, cloud notes, or email. MetaMask will never ask for your seed phrase inside a website — only in the extension itself during wallet import.
Adding BSC Network to MetaMask Manually
By default, MetaMask only shows Ethereum Mainnet and a few test networks. To use Binance Smart Chain, you must add it manually using the network settings. Here are the exact RPC parameters you need.
Official BSC Network Settings
New RPC URL: https://bsc-dataseed.binance.org
Chain ID: 56
Currency Symbol: BNB
Block Explorer URL: https://bscscan.com
Step-by-Step Instructions
Open MetaMask and Click the Network Dropdown
Click the MetaMask extension icon. At the top of the popup, you'll see "Ethereum Mainnet" (or your current network). Click on it to open the network selector.
Click "Add Network"
In the network dropdown, scroll down and click "Add Network." You'll be taken to the networks settings page in a new tab.
Click "Add a Network Manually"
At the bottom of the popular networks list, click "Add a network manually" to enter custom RPC settings.
Enter the BSC Network Details
Fill in: Network Name = "BNB Smart Chain", RPC URL = https://bsc-dataseed.binance.org, Chain ID = 56, Symbol = BNB, Block Explorer = https://bscscan.com. Click Save.
Switch to BNB Smart Chain
MetaMask will confirm the network was added. Click "Switch to BNB Smart Chain" or select it from the network dropdown. Your wallet address remains the same — only the active network changes.
Faster Alternative — Chainlist.org: Visit chainlist.org, search for "BNB Smart Chain" (Chain ID 56), and click "Add to MetaMask." This automatically fills all the network parameters for you — no manual entry required. Always verify you're on the official chainlist.org site.
Alternative RPC Endpoints for BSC
If the primary RPC (bsc-dataseed.binance.org) is slow or unresponsive, you can switch to one of these alternatives in MetaMask's network settings. Performance can vary by region and time of day.
- https://bsc-dataseed1.binance.org
- https://bsc-dataseed2.binance.org
- https://bsc-dataseed3.binance.org
- https://bsc-dataseed4.binance.org
- https://bsc-dataseed1.defibit.io
- https://bsc-dataseed1.ninicoin.io
To change your RPC, go to MetaMask Settings → Networks → BNB Smart Chain → edit the RPC URL field.
Importing BNB into MetaMask
After adding the BSC network, your MetaMask wallet has a BSC address but zero balance. You need BNB to pay gas fees for transactions. BNB is required for every BSC operation, including creating tokens — learn more about BNB gas fees.
Getting Your BSC Wallet Address
Ensure MetaMask is set to "BNB Smart Chain" network. Your wallet address (starting with 0x) is displayed in the account bar at the top of the MetaMask popup. Click it to copy. This same address works for BNB and all BEP-20 tokens.
Funding Methods
- From Binance Exchange: Withdraw BNB using the BEP20 (BSC) network to your MetaMask address
- Buy with Card: MetaMask has an on-ramp option (Portfolio → Buy). Select BNB Smart Chain and buy BNB directly with a card via Transak or MoonPay
- Transfer from Another Wallet: Send BNB from Trust Wallet or any BSC wallet to your MetaMask address
- Bridge from Ethereum: Use Binance Bridge or Stargate to convert ETH to BNB on BSC
Switching Networks in MetaMask
MetaMask can hold wallets for multiple EVM chains simultaneously. Your address is the same across all EVM chains, but your balances are separate. When using BSC dApps, always verify the network indicator at the top shows "BNB Smart Chain" before confirming any transaction.
Many dApps automatically prompt MetaMask to switch networks when you visit. If a site requests a network switch, review the Chain ID (56 for BSC) before approving. Scam sites sometimes request you add fake networks with misleading names but incorrect Chain IDs.
Connecting MetaMask to CreateBSCToken.com
With BSC configured and BNB in your wallet, connecting to CreateBSCToken.com is simple. MetaMask integrates directly as a browser extension — no QR code scanning needed.
Ensure You're on BNB Smart Chain
Check the MetaMask network indicator shows "BNB Smart Chain" (not Ethereum or another chain). Switch if needed via the network dropdown.
Visit CreateBSCToken.com
Navigate to createbsctoken.com in the same browser where MetaMask is installed. Click "Connect Wallet" on the homepage.
Select MetaMask
In the wallet selection modal, click "MetaMask." A MetaMask popup will appear asking for permission to connect.
Approve the Connection
Review the connection request — it shows the site URL and what permissions are requested (view your address). Click "Connect." Your wallet address will now appear on the site.
Fill in Token Details and Deploy
Complete your token's name, symbol, supply, and features. Click "Create Token" and confirm the gas fee transaction in MetaMask. Your token deploys in under 30 seconds.
For a full walkthrough of the token creation process itself, see our guide on how to create a BSC token.
Adding a Custom Token in MetaMask
After deploying a token on CreateBSCToken.com, you'll want to see it in your MetaMask balance. Most new tokens aren't listed automatically and must be added manually.
- Copy the token's contract address from the deployment confirmation
- In MetaMask, ensure you're on BNB Smart Chain network
- Scroll down to the bottom of the "Tokens" tab and click "Import tokens"
- Paste the contract address — the token symbol and decimals will auto-populate
- Click "Add Custom Token" then "Import Tokens"
- The token will now appear in your MetaMask portfolio
Tip: You can also view your token on BscScan by searching the contract address. BscScan shows the total supply, holder count, transaction history, and verified contract code — invaluable for confirming your token deployed correctly.
Common MetaMask Errors on BSC and How to Fix Them
Error: "Wrong Network"
This happens when you're connected to Ethereum or another chain while trying to use a BSC dApp. Fix: click the network dropdown in MetaMask and select "BNB Smart Chain." If BSC isn't in the list, you haven't added it yet — follow the steps above to add it manually or via Chainlist.
Error: "Insufficient Funds for Gas"
You don't have enough BNB to pay the transaction fee. Even a small amount of BNB (0.002–0.01 BNB) is needed for most transactions. Fund your wallet with BNB using any of the methods described above. Note: having BEP-20 tokens doesn't help — you specifically need BNB (native currency) for gas.
Error: "Transaction Underpriced" or "Replacement Transaction Underpriced"
This occurs when your gas price is too low or you're trying to replace a pending transaction with an insufficient gas bump. In MetaMask's transaction confirmation, click "Edit" on the gas fee and increase it. For stuck transactions, use "Speed Up" in the Activity tab.
Error: "Nonce Too Low"
A nonce mismatch means a previous transaction is pending or there's a sync issue. Try resetting your account in MetaMask: Settings → Advanced → Reset Account (this clears local transaction history but does not affect on-chain funds or tokens).
MetaMask Showing Wrong Balance
Sometimes MetaMask doesn't refresh balances automatically. Click the three dots in your account and select "Refresh list" or simply switch to another network and back to BSC to force a balance refresh.
MetaMask Security Best Practices
MetaMask is a high-value target for attackers because it sits in your browser where malicious websites can interact with it. Follow these guidelines to stay safe.
- Never enter your seed phrase anywhere except MetaMask itself during a fresh wallet import
- Lock MetaMask when not in use — click your account icon and "Lock." Require your password on every browser session
- Verify transaction details before confirming — check the contract address and function name, not just the gas amount
- Review token approvals regularly — use revoke.cash on BSC to remove unlimited approval permissions granted to old dApps
- Use a hardware wallet for large holdings — MetaMask integrates with Ledger and Trezor devices, keeping your keys offline
- Install only the official MetaMask extension — check the Chrome Web Store ID is nkbihfbeogaeaoehlefnkodbefgpgknn
- Enable MetaMask's phishing detection — it's on by default and warns you about known scam sites
- Be cautious of suspicious airdropped tokens — interacting with them can trigger approval scams
Critical: MetaMask will NEVER contact you by email, Discord, Twitter, or Telegram asking for your seed phrase. All "MetaMask Support" accounts in social media asking for your phrase are scammers. The only legitimate MetaMask support is at support.metamask.io.

Frequently Asked Questions
Why can't I see BSC in MetaMask after installing?
MetaMask ships with Ethereum Mainnet pre-configured. BSC (BNB Smart Chain) must be added manually because it's a separate blockchain, not an Ethereum network. Use the exact settings in this guide: RPC URL https://bsc-dataseed.binance.org, Chain ID 56, Symbol BNB. Alternatively, visit chainlist.org and click "Add to MetaMask" next to BNB Smart Chain for one-click setup. Once added, BSC will appear in your network dropdown permanently.
What is Chain ID 56 and why does it matter?
Chain ID is a unique number that identifies a specific blockchain network. BSC Mainnet uses Chain ID 56. MetaMask uses this to prevent replay attacks and ensure transactions are broadcast to the correct chain. If you enter the wrong Chain ID, MetaMask will reject the network or behave unexpectedly. BSC Testnet uses Chain ID 97 and should only be used for testing — never send real BNB to a testnet address. Always double-check you're on Chain ID 56 for real transactions.
Can MetaMask hold both ETH (Ethereum) and BNB (BSC) at the same address?
Yes and no. Your wallet address (0x...) is the same on both chains, but the balances are completely separate and independent. ETH exists on Ethereum, BNB exists on BSC — they're different assets on different blockchains that happen to share address format. You switch between them using the network selector. MetaMask shows your balance for whichever network is currently active. This means you could have 1 ETH on Ethereum and 0.5 BNB on BSC, both accessible from the same MetaMask account.
My transaction has been pending for a long time — what should I do?
Pending transactions usually mean your gas price was too low for current network congestion. In MetaMask's Activity tab, find the pending transaction and click "Speed Up" to resubmit with a higher gas price. Alternatively, "Cancel" submits a zero-value transaction with the same nonce but higher gas to replace it. If neither works, you can reset your account in Settings → Advanced → Reset Account, which clears the local transaction queue (your funds are unaffected). BSC is generally fast and cheap, so pending transactions resolve quickly compared to Ethereum.
How do I know which network my MetaMask is on?
The current network is always displayed in the top-center of the MetaMask popup — it shows the network name (e.g., "BNB Smart Chain" or "Ethereum Mainnet"). When on BSC, the currency symbol will be BNB. You can also check by looking at your balance: if it shows ETH, you're on Ethereum; if it shows BNB, you're on BSC. Always verify you're on the correct network before confirming any transaction, especially when using multiple chains.
Is it safe to create a BEP-20 token using MetaMask on CreateBSCToken.com?
Yes. CreateBSCToken.com uses a standard BEP-20 token factory contract. When you click "Create Token," MetaMask shows you exactly what transaction is being executed, including the gas fee and contract address. You're not giving the site any special permissions — you're simply sending a transaction to a public smart contract. Your private keys never leave MetaMask. The site cannot access your wallet or funds without your explicit approval for each individual transaction. Always review the transaction details before clicking "Confirm."
Can I use MetaMask on mobile for BSC token creation?
Yes. MetaMask's mobile app includes a built-in browser (tap the Browser tab). Navigate to createbsctoken.com, connect your wallet, and proceed exactly as on desktop. The mobile experience is slightly more compact but fully functional. You'll need to add the BSC network in the mobile app separately — go to Settings → Networks → Add Network and enter the same parameters. Make sure you have BNB in your mobile MetaMask wallet to pay gas fees.
What is the difference between a MetaMask "password" and "seed phrase"?
These are two completely different security layers. Your password encrypts your wallet data on your specific device — it's used to unlock MetaMask after closing your browser. If you reinstall your browser, lose your computer, or clear browser data, the password becomes useless. Your seed phrase (Secret Recovery Phrase) is the master key that recreates your entire wallet on any device — it works on MetaMask, Trust Wallet, or any compatible wallet app. The seed phrase never changes and must be stored offline. Your password protects local access; your seed phrase protects your actual funds.
