Coinbase Extension® — Getting Started | Coinbase Wallet®

Introduction

The Coinbase Extension®, commonly known as the Coinbase Wallet® browser extension, is designed to provide a secure and seamless way to interact with decentralized applications (dApps), manage digital assets, and maintain full control over private keys directly from your browser. Unlike custodial exchanges, the extension gives users self-custody, meaning you alone control your funds, keys, and on-chain identity.

This comprehensive guide walks you through getting started with the Coinbase Extension®, from installation and setup to advanced usage, security practices, and ecosystem integration. Throughout the guide, you will find interlinking references that connect related sections, helping you navigate topics efficiently and build a complete understanding.

What Is the Coinbase Extension®?

The Coinbase Extension® is a non-custodial Web3 wallet that operates as a browser extension. It allows users to:

Store and manage cryptocurrencies and NFTs
Connect directly to dApps across multiple blockchains
Swap tokens within the wallet interface
Interact with DeFi platforms, NFT marketplaces, and Web3 games

Unlike centralized wallets, the extension does not hold your private keys. These are encrypted and stored locally on your device, ensuring autonomy and privacy.

Supported Browsers and System Requirements

The Coinbase Extension® is compatible with major Chromium-based browsers and Firefox. Before installing, ensure your system meets the basic requirements:

Updated browser version
Stable internet connection
Secure device environment (password-protected OS)

Using the extension on a personal device is strongly recommended to minimize security risks.

Installing the Coinbase Extension®

Installation is straightforward and typically takes only a few minutes:

Open your preferred supported browser
Navigate to the official extension marketplace
Search for “Coinbase Wallet”
Verify the publisher details
Add the extension to your browser

Once installed, the Coinbase icon appears in your browser toolbar, giving you instant access to your wallet.

Interlinking: After installation, proceed directly to Wallet Setup and Account Creation.

Wallet Setup and Account Creation

After installing the extension, you will be prompted to either create a new wallet or import an existing one.

Creating a New Wallet

When creating a new wallet:

Set a strong, unique password
Generate a recovery phrase (seed phrase)
Confirm the recovery phrase in the correct order

This phrase is the only way to recover your wallet if you lose access.

Importing an Existing Wallet

If you already have a wallet:

Select the import option
Enter your existing recovery phrase
Set a new local password

Interlinking: To understand why recovery phrases are critical, see Understanding Recovery Phrases.

Understanding Recovery Phrases

A recovery phrase is a series of randomly generated words that represent your private keys. Anyone with access to this phrase can control your assets.

Best practices include:

Writing the phrase on paper
Storing it offline in a secure location
Never sharing it digitally or verbally

Avoid screenshots, cloud storage, or messaging apps for storing recovery phrases.
