Coinbase Extension™ — Getting Started | Coinbase®
The Coinbase Extension™ is a browser-based crypto wallet designed to help users safely access decentralized applications, manage digital assets, and explore the growing Web3 ecosystem. Developed by Coinbase®, this extension combines ease of use with strong security features, making it suitable for both beginners and experienced crypto users.
This guide explains how the Coinbase Extension™ works, how to get started, and what to keep in mind when using it for everyday crypto activities.
What Is the Coinbase Extension™?
The Coinbase Extension™ is a non-custodial wallet that runs directly inside your web browser. Unlike traditional exchange wallets, it gives users full ownership of their private keys, meaning you stay in control of your funds at all times.
The extension allows you to interact with decentralized finance (DeFi) platforms, NFT marketplaces, and blockchain-based apps without relying on a centralized service. It supports Ethereum and other compatible networks, enabling smooth interaction with Web3 platforms.
Key highlights include: • Self-custody of crypto assets • Simple browser integration • Secure transaction approvals • Direct connection to dApps
How Coinbase Extension™ Works
Once installed, the Coinbase Extension™ acts as a secure gateway between your browser and blockchain networks. When you visit a decentralized app, the extension prompts you to connect your wallet and approve actions such as token swaps or NFT purchases.
Every transaction must be manually confirmed, helping prevent accidental or unauthorized activity. Sensitive data, including private keys, stays stored locally on your device rather than on Coinbase® servers.
This approach gives users more transparency and control over how their crypto is used.
Installing the Coinbase Extension™
Getting started with the Coinbase Extension™ takes only a few minutes:
- Open the official Coinbase® website or your browser’s extension store
- Download and install the Coinbase Extension™
- Pin the extension to your browser toolbar
- Launch the extension to begin setup
During installation, always verify that you are downloading the official extension to avoid fake or malicious copies.
Creating a New Wallet or Importing One
When you open the Coinbase Extension™, you’ll be asked to choose between two options:
Create a New Wallet
This option generates a brand-new wallet along with a unique recovery phrase. This phrase is essential for restoring your wallet if your device is lost or damaged.
Import an Existing Wallet
If you already have a wallet, you can import it using your existing recovery phrase. This allows you to manage your assets through the Coinbase Extension™ without creating a new wallet.
In both cases, you’ll create a strong password to protect access on your device.
⚠️ Important: Never share your recovery phrase with anyone. Coinbase® will never ask for it.
Using the Coinbase Extension™ Daily
Once set up, the Coinbase Extension™ can be used for a wide range of Web3 activities.
Common uses include: • Sending and receiving crypto • Connecting to decentralized exchanges • Managing NFTs • Approving smart contract interactions • Switching between supported networks
The interface clearly displays transaction details, including fees and permissions, before you confirm any action. This transparency helps users make informed decisions while navigating decentralized platforms.
Security Tips for Safe Usage
While the Coinbase Extension™ includes built-in security protections, user awareness is critical.
Best practices include: • Store your recovery phrase offline • Avoid clicking unknown links • Check website URLs carefully • Review transaction prompts before approving • Keep your browser updated
Because the wallet is non-custodial, responsibility for asset safety rests entirely with the user.
Coinbase Extension™ vs. Exchange Wallets
A key difference between the Coinbase Extension™ and a Coinbase® exchange wallet is ownership. Exchange wallets are custodial, meaning Coinbase® manages the private keys. The extension, however, gives you full control.
This makes the Coinbase Extension™ ideal for users who want direct access to DeFi, NFTs, and Web3 tools while maintaining self-custody of their funds.
Who Should Use the Coinbase Extension™?
The Coinbase Extension™ is well suited for: • Web3 beginners • NFT collectors • DeFi users • Coinbase® account holders exploring self-custody
Its balance of simplicity and control makes it a strong choice for anyone stepping beyond centralized crypto platforms.
