The Binance Web3 Wallet browser extension supports Chrome, Edge, Brave, and Firefox, and can be downloaded from the Chrome Web Store or the Binance official site. It is an independent wallet from the mobile APP wallet—the two have different addresses and require importing a seed phrase to sync as the same wallet. You need to have a Binance account first; register from the Binance official site, get the APK via the Binance official APP, and see the full-platform process in the Download Center. This article explains the extension installation and its relationship with the mobile app.

Initialization After Installation
When you open the extension for the first time:
Option 1: Create a New Wallet
- Select "Create Wallet".
- Set a transaction password (6 digits or alphanumeric combination).
- Backup the seed phrase (12 English words, write them down by hand).
- Verify the seed phrase.
- Complete creation.
Option 2: Import an Existing Wallet
If you want to sync your mobile APP wallet to your computer:
- Select "Import Wallet".
- Select "Import with Seed Phrase".
- Enter the 12 seed phrases from your mobile wallet.
- Set a new transaction password (independent password for PC).
- Complete import.
After importing, the PC extension and the mobile APP are the same wallet (same address, same assets).
Option 3: Connect Hardware Wallet
- Select "Connect Hardware Wallet".
- Choose Ledger / Trezor.
- Connect your hardware wallet via USB.
- Follow the hardware wallet prompts to complete the connection.
The Relationship Between the Browser Extension and the Mobile APP
Many beginners assume that the Binance wallet automatically syncs between PC and mobile. In fact, they are independent wallets by default:
| Item | Default Status |
|---|---|
| Wallet Address | Different |
| Assets | Not shared |
| Transaction Password | Independent |
| History | Independent |
| Web3 Wallet ID | Different |
To make the two sync, you must import via the same seed phrase:
- Create a wallet on the mobile APP → backup the seed phrase.
- In the browser extension, "Import Wallet" → enter the same seed phrase.
- Now, both sides are the same wallet.
Or, use the MPC mode to log into the same Binance account (supported in some scenarios).
Common Uses for the Browser Extension
1. Large Screen DeFi Operations
- DeFi protocols like Uniswap, Aave, and Curve are more convenient in desktop browsers.
- View different data across multiple windows.
- Complex operations (batch transactions, contract calls).
2. NFT Trading
- NFT platforms like OpenSea, Blur.
- Browsing a large number of NFTs is more comfortable on a large screen.
- Batch listing/purchasing operations are smoother.
3. Blockchain Games
- Some blockchain games require a browser extension to play.
- Web versions of StepN, Pixels require a wallet.
4. Cross-Chain Bridges
- Cross-chain bridges like LayerZero, Wormhole.
- Desktop operations are more precise.
5. Multi-Account Management
- The browser extension can create multiple wallet accounts.
- One account for primary funds, another for exploring unfamiliar DApps.
Safe Usage Tips
1. Only Install From Official Channels
- On the Chrome Web Store, make sure the developer is "Binance".
- It should have a 4.0+ rating and thousands of reviews.
- Do not download .crx files from other IP addresses for offline installation.
2. Beware of "Binance Wallet" Fake Extensions
- Fake extensions usually have suffixes like Pro / Plus / Helper in the developer name.
- The genuine Binance extension developer is exactly "Binance".
- Double check before installing.
3. Lock Screen Password
- After setting the transaction password, the extension will lock automatically after brief inactivity.
- Any operation requires re-entering the password after it locks.
- Even if someone else gets your computer, they cannot directly transfer your assets.
4. Do Not Let Your Browser Remember Your Transaction Password
- Passwords saved in browser password managers could be read by other extensions.
- Memorize your transaction password yourself or write it in a dedicated password manager (do not let the browser autofill).
5. Regularly Review DApp Authorizations
- The browser extension records all DApps you've authorized.
- Regularly clean up authorizations that you no longer use.
- Use revoke.cash to check on-chain authorizations.
Coexisting with MetaMask
If you already have MetaMask installed, can you install the Binance extension at the same time?
Yes. The two extensions do not conflict. Every DApp will let you choose which one to connect when linking a wallet.
Practical usage advice:
- Activate only one wallet extension at a time (to avoid misconnections).
- When not needed, "Disable" it from the extension menu in the upper right corner of your browser.
- Verify which wallet is connected during important operations.
Uninstallation and Data Handling
If you no longer use the browser extension:
Uninstallation Steps
- Chrome / Edge: Right-click the extension icon → "Remove from Chrome / Edge".
- Firefox: Add-ons and themes → find Binance Wallet → Remove.
Data Cleanup
Uninstalling only removes the extension itself; it does not affect:
- Assets on the blockchain (they remain on-chain).
- The seed phrase you safeguarded.
If you want to completely "erase usage traces":
- Transfer your assets out before uninstalling.
- Uninstall the extension.
- Browser: Settings → Privacy → Clear browsing data.
Frequently Asked Questions
Q: Do the extension and the mobile APP have to be synced? A: Not necessarily. You can create separate, independent wallets for different scenarios (e.g., mobile for daily use, PC for DeFi).
Q: Can the extension be installed on multiple browsers? A: Yes. You can install it on Chrome, Edge, and Firefox simultaneously, but they are separate independent wallets by default and require syncing via the seed phrase.
Q: How much storage does the extension use? A: Around 30-50MB, equivalent to the size of a small application.
Q: Is the extension's seed phrase the same as the mobile APP's? A: By default, no. If you use "Import Wallet" in the extension and input your mobile's seed phrase, the two will sync.
Q: What if I forget the transaction password? A: The transaction password can be reset via the seed phrase—you set a new password when you re-import the wallet. Thus, the seed phrase is far more important than the password.
Q: Will the extension steal my money? A: Not if installed from the official channel. But fake or altered extensions might. Always verify the developer is Binance before installing.
Summary
The Binance Web3 Wallet browser extension supports Chrome / Edge / Brave / Firefox; search for "Binance Web3 Wallet" in the corresponding store to install it (the developer must be Binance). It is independent of the mobile APP wallet by default; they do not automatically sync, requiring you to import the same seed phrase to sync the identical wallet. The first thing to do after installation is to set a transaction password and hand-write your seed phrase on paper for safekeeping. Common scenarios involve large-screen DeFi operations, NFT trading, cross-chain bridges, and other on-chain activities requiring complex operations.
