Coinbase Extension® | Getting™ Started — Complete Access & Setup Guide

The Coinbase Extension® is designed to help users securely access Web3 applications, manage crypto assets, and interact with decentralized finance (DeFi) platforms directly from their browser. As Web3 adoption grows, browser extensions have become essential tools for fast, secure, and convenient crypto management.

This guide explains how the Coinbase browser extension works, how to set it up, and how to use it safely for everyday crypto and Web3 activities.

What Is Coinbase Extension®?

The Coinbase browser extension is a non-custodial Web3 wallet extension that allows users to:

  • Store and manage cryptocurrencies
  • Connect to decentralized applications (dApps)
  • Send and receive digital assets
  • Manage NFTs
  • Access DeFi platforms and Web3 services

Unlike exchange accounts, the extension wallet typically gives users direct control over private keys and recovery phrases.
