The Coinbase Extension, commonly referred to as the Coinbase Wallet browser extension, is a powerful tool that allows users to interact directly with the decentralized web (Web3) from their desktop browser. Designed to work seamlessly with the Coinbase Wallet ecosystem, the extension enables you to store crypto assets, manage NFTs, connect to decentralized applications (dApps), and approve blockchain transactions—all without leaving your browser.
This guide walks you through everything you need to know to get started, from installation and setup to everyday use and security best practices.
The Coinbase Wallet extension is a self-custody Web3 wallet. Unlike a centralized Coinbase exchange account, this wallet gives you full control over your private keys and digital assets. It acts as a bridge between your browser and blockchain networks such as Ethereum and other EVM-compatible chains.
With the extension, you can:
Because it’s a self-custody wallet, you—not Coinbase—control your funds.
Before installing the extension, make sure your system meets the basic requirements:
Mobile users should use the standalone Coinbase Wallet mobile app, as the extension is designed specifically for desktop browsers.
Getting started begins with installing the extension in your browser.
Navigate to your browser’s official extension store and search for Coinbase Wallet. Always verify that the publisher is Coinbase to avoid fake or malicious extensions.
Click Add to Browser (or equivalent) and approve the installation. Once installed, the Coinbase Wallet icon will appear in your browser toolbar.
For easy access, pin the extension so it’s always visible in your toolbar.
When you open the extension for the first time, you’ll be prompted to either create a new wallet or import an existing one.

Once connected, the dApp can read your wallet address and request transaction approvals—but cannot move funds without your confirmation.
To receive funds:
Always double-check the network being used (e.g., Ethereum vs. another chain).
To send funds:
Transactions are broadcast to the blockchain and may take time depending on network congestion.
The Coinbase Wallet extension also supports NFTs.
You can:
NFTs are displayed visually, making it easy to manage digital collectibles directly from your browser.
Using a self-custody wallet comes with responsibility. Follow these best practices to protect your assets:
