What is the Coinbase Wallet Extension?
The Coinbase Wallet Extension is a browser-based crypto wallet that enables users to access decentralized apps (dApps), manage assets, and interact with the Ethereum and other blockchain networks securely—all without leaving the browser.

Key security features include:
- Encrypted storage of private keys within the browser.
