An informational overview of the Coinbase Extension® browser wallet

Introduction

The Coinbase Extension® is a browser-based cryptocurrency wallet designed to help users interact with decentralized applications (often called “dApps”) and manage digital assets directly from a supported web browser. This page provides a general, educational overview of the Coinbase Extension®, its purpose, and its core concepts.

This content is intended to explain features and high-level functionality only. It does not provide financial advice, investment guidance, or step-by-step instructions for trading or account creation.

Age Requirement Notice:

Coinbase products and services are generally intended for users who are 18 years of age or older, depending on local laws and regulations. If you are under 18, you should not attempt to create or use a Coinbase account on your own. Always speak with a parent or legal guardian and review official Coinbase policies before engaging with any cryptocurrency-related services.

What Is the Coinbase Extension®?

The Coinbase Extension® is a self-custody wallet that runs as a browser extension. A self-custody wallet means that the user is responsible for safeguarding their wallet credentials, such as recovery phrases and private keys. Unlike centralized platforms, a self-custody wallet allows users to interact directly with blockchain networks.

The extension is commonly used to:

  • View and manage supported digital assets
  • Connect to decentralized applications (dApps)
  • Review transaction requests before approval
  • Interact with Web3 services through a browser

The Coinbase Extension® is designed to integrate with modern blockchain ecosystems while maintaining a user-friendly interface.

Core Features Overview

Browser-Based Access

As a browser extension, the Coinbase Extension® allows users to access wallet functionality without switching between multiple applications. Once installed in a supported browser, it can interact directly with compatible websites.

<h3>Self-Custody Wallet Model</h3>
<p>
  The self-custody model places responsibility on the user rather than a centralized service.
  This approach offers more direct control but also requires careful security practices.
</p>

<h3>dApp Connectivity</h3>
<p>
  Many decentralized applications request wallet connections to function. The Coinbase
  Extension® provides a way to review and approve these connection requests before any
  interaction occurs.

Security Principles and Best Practices

Security is a critical aspect of any digital wallet. While the Coinbase Extension® includes built-in safeguards, users are responsible for following good security habits.

  • Never share recovery phrases or private keys
  • Be cautious when connecting to unfamiliar websites
  • Review transaction details carefully before approval
  • Keep browsers and extensions up to date

Understanding these principles helps reduce the risk of unauthorized access or accidental loss of digital assets.

Understanding Transactions and Approvals

When interacting with blockchain applications, users are often asked to approve actions such as connections or transactions. The Coinbase Extension® displays these requests so users can review relevant information before making a decision.

Taking time to understand what a request is asking for is an important habit, especially in decentralized environments where actions may be irreversible.
