Setting Up and Using the Trust Wallet Browser Extension
The Trust Wallet browser extension is NOT the same as the mobile app and has different security considerations:
Separate Seed Phrase: The extension creates a new wallet with a new seed phrase by default
No Mobile Sync: It doesn't automatically sync with your mobile Trust Wallet
Impersonator Risk: Many fake Trust Wallet extensions exist - only download from official sources
Phishing Targets: Browser extensions are common targets for phishing attacks
