Coinbase Wallet Extension – Complete Guide

Coinbase Wallet Extension is a browser-based wallet developed by Coinbase that allows users to securely manage their cryptocurrencies, access decentralized applications (dApps), and interact with DeFi protocols directly from their browser. Unlike the standard Coinbase app or exchange accounts, the Coinbase Wallet Extension is self-custodial, meaning you control your private keys.

This guide explains how the Coinbase Wallet Extension works, how to install and set it up, and best security practices for managing digital assets.

What Is Coinbase Wallet Extension?

The Coinbase Wallet Extension is a browser extension available for Chrome, Firefox, Edge, and other Chromium-based browsers. It provides a seamless interface for interacting with cryptocurrencies and decentralized applications (dApps) directly from your web browser.

Key features include:

  • Self-custody of funds – You retain full control of your private keys.
  • dApp integration – Connect to Ethereum, Binance Smart Chain, Polygon, and other blockchain networks.
  • Secure transactions – All transactions must be approved within the extension.
  • Multi-asset support – Manage ETH, ERC-20 tokens, NFTs, and other assets.
