The current crypto user experience often forces trade-offs between convenience and security. Users either rely on custodial platforms (convenient but with custodial risk) or self-custody (secure but complex). The Coinbase Extension aims to combine simplicity with strong security guarantees, bridging both worlds.
Confusing wallet setups, phishing attacks, and slow on-ramp for new users cause lost funds and poor retention.
Offer a trusted, easy-to-use extension with clear UX and built-in anti-phishing protections to increase adoption and retention.
The extension focuses on three pillars: Secure key management, Fast trading flow, and Transparent account controls.
Hardware-backed encryption, optional passphrase, and secure backup (encrypted cloud backup or seed phrase). Users always own their private keys.
Integrated trading widget, limit / market order support, price alerts, and one-click gas optimization for EVM chains.
Granular site permissions, ephemeral signing sessions, and privacy-preserving analytics that users can opt out of.
At-a-glance portfolio, token performance, tax-friendly exports, and watchlists with alerts.
Security is the top priority. The extension uses modern best practices to minimize attack surface and protect user funds.
Note: Users are encouraged to enable hardware signers for high-value accounts and to store recovery material offline.
Always double-check the active domain before approving signatures.
Design clear flows for new and returning users. Keep friction low while enforcing security best practices.
1) Install the extension.
2) Create or import a wallet (seed phrase) with optional cloud-encrypted backup.
3) Quick guided tour showing how to connect to dApps safely and how to check transaction details.
Fast unlock (biometrics / OS-level PIN) for everyday tasks, with an option to require full re-authentication for high-value actions.
Approve this signature — Confirm you trust app.example.com to view your address and request a signature for a message. Check the message content and gas estimate before approving.
This roadmap is a suggested path to launch and iteratively improve the extension.
Q: Is Coinbase still custodian if I use the extension?
A: No. The extension can operate in self-custody mode where private keys remain under the user’s control. Coinbase services may be offered as optional integrations.
Q: How does backup work?
A: Users can export a standard seed phrase or choose an encrypted cloud backup protected by a separate passphrase — Coinbase does not store the raw seed without user consent.
