What is MetaMask?
MetaMask is a crypto wallet available as a browser extension (Chrome, Firefox, Brave) and mobile app (iOS, Android). It is the most widely used wallet for DeFi, with over 30 million monthly active users. MetaMask stores your private keys locally and allows you to interact with any EVM-compatible blockchain.
Setting up MetaMask for BNB Smart Chain
By default, MetaMask connects to Ethereum. To use BSC DeFi protocols like TurboLoop:
- Open MetaMask → Settings → Networks → Add Network
- Enter BSC network details:
- Network Name: BNB Smart Chain
- RPC URL: https://bsc-dataseed.binance.org/
- Chain ID: 56
- Symbol: BNB
- Block Explorer: https://bscscan.com
Or use Chainlist.org to add BSC automatically.
MetaMask security best practices
- Never share your seed phrase — MetaMask support will never ask for it
- Use a hardware wallet with MetaMask for large holdings
- Check URLs carefully — phishing sites mimic MetaMask's interface
- Review transaction details before signing — check the contract address and what you're approving
MetaMask vs Trust Wallet
Both work for BSC DeFi. MetaMask is better for desktop users; Trust Wallet is better for mobile-first users. Both support BNB Smart Chain and all BEP-20 tokens.
