Mission
Why the Coinbase browser extension exists
The Coinbase Extension makes managing cryptocurrency accessible, secure, and private. This presentation explains how the extension protects users, practical safety practices, and how teams can communicate security best practices to customers. We emphasize clear controls, transaction transparency, and seamless recovery options.

Key Features
What users interact with every day
Secure Key Management
Private keys are encrypted locally with a strong passphrase. The extension never sends private keys to the cloud. Users can opt for hardware-wallet pairing for an added layer of security.
Transaction Review
Before signing, users see a clear summary: destination address, network fees, token amounts, and a human-readable explanation of unusual permissions.
Phishing Protections
Visual site indicators, domain verification, and optional URL-whitelisting reduce the risk of malicious dapps requesting access to funds.
Recovery & Backup
Assisted seed backup flows, optional cloud-encrypted backups, and step-by-step recovery guides make account recovery straightforward while preserving security.
Security Best Practices
Recommended actions for users and teams
Use a unique, strong extension passphrase and enable biometric unlock where supported.
Pair with a hardware wallet for large balances and high-value transactions.
Keep browser and extension updated; enable auto-updates.
Verify dapp permissions and limit approvals to necessary token allowances.
Educate staff and customers about phishing tactics and URL spoofing.

Open the extension and authenticate with passphrase/biometrics.
Review balance, assets, and recent activity on the dashboard.

Extension shows a concise permission panel explaining any token approvals requested by a dapp.
User confirms signature; the extension signs locally and broadcasts the transaction.

Incident Response
How to respond if a user reports compromise
Immediate guidance: instruct user to disconnect extension, revoke dapp approvals, and move funds to a secure wallet.
Support flow: gather device/browser details, timestamped screenshots, and transaction hashes when available.
Forensics: preserve logs, replicate the issue on a test environment, and escalate to engineering/security teams.
FAQ & Closing
Common user concerns answered
Is my seed stored by Coinbase?
No. Seeds and private keys reside locally and are encrypted. Optional cloud backups are encrypted with user-controlled keys.
What if I lose my seed?
Follow the extension’s guided recovery flow; if you cannot recover, funds cannot be restored. Emphasize safe offline backup practices.
