Coinbase Extension® — Getting Started
The Coinbase Extension® is a powerful browser-based crypto wallet designed to help users securely store, manage, and interact with digital assets directly from their web browser. Built for Web3 users, the Coinbase Extension enables seamless access to decentralized applications (dApps), NFTs, DeFi platforms, and crypto transactions — all while keeping control in the user’s hands.
This getting started guide explains what the Coinbase Extension is, how it works, and how to set it up safely for everyday crypto use.
What Is Coinbase Extension®?
The Coinbase Extension® is a self-custody wallet extension available for supported web browsers. Unlike centralized exchange accounts, this extension allows users to fully control their private keys and interact directly with blockchain networks.
It acts as a bridge between your browser and the decentralized web, making it easy to connect to dApps, manage tokens, store NFTs, and sign transactions securely.
Why Use Coinbase Extension®?
The Coinbase Extension® is designed for users who want convenience without sacrificing security.
Key Benefits:
- Self-custody wallet (you control your keys)
- Easy dApp and Web3 access
- Clean and beginner-friendly interface
- NFT and token support
- Secure transaction approvals
- Seamless connection to decentralized platforms
Whether you are new to crypto or an experienced Web3 user, the Coinbase Extension® offers a reliable way to explore blockchain technology.
Supported Browsers
The Coinbase Extension® is compatible with popular browsers such as:
- Google Chrome
- Chromium-based browsers
Always install the extension from the official browser extension store to avoid fake or malicious copies.
How to Get Started with Coinbase Extension®
Step 1: Install the Coinbase Extension®
Visit the official browser extension store and search for Coinbase Extension®. Confirm the publisher is Coinbase before installing.
Once installed, the extension icon will appear in your browser toolbar.
Step 2: Create a New Wallet or Import an Existing One
When you open the extension for the first time, you will see two options:
- Create a new wallet
- Import an existing wallet
If you are new, choose “Create a new wallet.” If you already have a wallet, you can restore it using your recovery phrase.
Step 3: Secure Your Recovery Phrase
The extension will generate a recovery phrase (also called a seed phrase). This phrase is the only way to recover your wallet if you lose access.
Important security tips:
- Write it down on paper
- Store it offline
- Never take screenshots
- Never share it with anyone
Coinbase will never ask for your recovery phrase.
Step 4: Set a Strong Password
Create a strong password to protect your wallet locally on your browser. This password is required to unlock the extension but does not replace your recovery phrase.
