Coinbase Extension® — Getting Started | Coinbase®

The Coinbase Extension® is a browser-based crypto wallet designed to simplify how users interact with digital assets, decentralized applications (dApps), NFTs, and Web3 platforms. Unlike centralized exchange dashboards, the extension gives users direct control over their private keys while still connecting seamlessly to the wider Coinbase ecosystem. This guide explains everything you need to know to get started, from installation to advanced usage, while clearly showing how different topics interlink.

Understanding the Coinbase Extension®

The Coinbase Extension® functions as a non-custodial wallet that lives inside your browser. It allows you to store crypto assets, sign transactions, interact with decentralized finance platforms, and manage NFTs—all without leaving your browser window.

Unlike traditional exchange logins, the extension does not require you to rely on a third party to hold your assets. You retain ownership of your private keys, which are stored securely on your device.

Creating or Importing a Wallet

After installation, users can either create a new wallet or import an existing one.

Creating a New Wallet

When creating a new wallet, the extension generates a unique recovery phrase. This phrase is the only way to restore your wallet if your device is lost or damaged.

Important considerations:

Store the recovery phrase offline
Never share it with anyone
Avoid cloud storage or screenshots

Importing an Existing Wallet

If you already use a Web3 wallet, you can import it using your recovery phrase. This allows continuity across platforms without creating multiple wallets.
