FAQs: Critical User Concerns

Q1: Can I access my Coinbase® exchange funds via the extension?

No. The extension is a separate self-custody wallet. Transfer manually: Exchange → "Send" → Paste wallet address (network fees apply).

Q2: "Transaction failed" despite sufficient balance?

  • Fix 1: Increase gas fee (adjust "Priority" slider)
  • Fix 2: Confirm correct network (e.g., Base ≠ Ethereum)
  • Fix 3: Clear cache: Extension → Settings → "Reset Account"

Q3: How to recover after computer loss?

  1. Install extension on new device
  2. Select "Recover with recovery phrase"
  3. Enter 12 words → Set new password 🚫 Never share phrase with "support" agents

Q4: Why choose this over MetaMask®?

  • ✅ Pros: Built-in fiat purchases + Coinbase® ecosystem integration
  • ❌ Cons: Fewer supported chains (e.g., no Arbitrum Nova)
  • ⚠️ Both: Require equal recovery phrase security

Q5: Are funds FDIC-insured?

No. Self-custody = Your responsibility. Use hardware wallets for >$1k assets.

Q6: Can I connect a Ledger®?

Not natively. For hardware security, use MetaMask® + Ledger® then transfer assets.
