Coinbase Extension — Secure Browser Access to Your Crypto Wallet
Welcome — this short presentation explains the Coinbase browser extension: what it does, why security matters,
and how teams and individuals can adopt it. The extension is designed to provide a compact, secure, and user-friendly
interface to access your Coinbase-managed crypto assets from any Chromium-based browser without exposing your
private keys or creating unnecessary friction.
Quick Access
Sign in once and unlock a safe, persisted session to authorize transactions, view balances, and manage tokens.
Key Management
Private keys remain encrypted locally and never leave your device. Transactions are signed inside the extension.
Network Support
Compatible with major networks and token standards; supports Ethereum, L2s, and common wallets connectivity.
Developer Tools
Built-in connection inspector for dApp permissions, safe transaction simulation, and clear revoke controls.
Connected: Coinbase Wallet

Security Model & Best Practices
Security centers on three pillars: local encryption of keys, granular permission prompts, and recoverability.
The extension encrypts private keys with a passphrase and stores them in the browser's secure storage. When dApps
request access to accounts, the extension surfaces a clear permission dialog that lists requested accounts,
scopes (signing vs. viewing), and suggested gas limits. Users should enable biometric unlock (if available),
set a strong passphrase, and make regular backups of their recovery phrase.
Encryption AES-256 local encryption for private key material.
Transaction Preview Human-readable previews and simulation before signing.
Revoke One-click revoke for unused approvals and third-party allowances.
Tip: Treat the extension as a secure bridge — keep sensitive operations on hardware wallets when available,
and use the extension for day-to-day interactions with well-known dApps.
User Experience & Interface
The UI focuses on clarity and quick decision-making: large approve/deny actions, clear fee breakdowns,
and readable contract data. The extension groups recurring approvals, surfaces historical actions, and
includes an activity feed so users can audit past authorizations. Accessibility features include keyboard
navigation and screen reader labels.
Transaction Feed See pending, signed, and failed transactions in one place.
Account Switch Fast multi-account switching without re-authenticating.
Notifications Local, browser notifications for important events.
Accessibility ARIA labels, contrast-aware color palette, and keyboard-first flows.
Adoption, Integrations & Roadmap
Coinbase Extension is built for consumers and developers. dApp teams can integrate via standard wallet connectors
(EIP-1193 / WalletConnect compatibility), while enterprises can leverage managed policies for corporate accounts.
The roadmap includes hardware wallet passthrough, advanced multisig UX, and deeper support for rollups and token flows.
Developers Standard connector + sample SDKs for quick onboarding.
Enterprises Policy-driven approvals and shared account visibility.
Roadmap Hardware wallet integration and multi-chain simplification.
Community Open feedback channels and security bounties.
Final note: security is a shared responsibility — use the extension as a hardened interface and combine it with good
operational security: keep software up to date, avoid phishing links, and verify contract addresses before signing.
Get Started — Next Steps
Install the extension from the official Coinbase distribution channel, create or import a wallet using your recovery
phrase, enable optional biometric unlock, and connect to one trusted dApp to test the flow. For teams, evaluate
the enterprise policy features and run an internal security review before broad rollout.
