Coinbase Extension® — Getting Started | Coinbase Wallet®
The Coinbase Extension® is a browser-based crypto wallet that lets you store, manage, and interact with digital assets directly from your desktop. Built as part of Coinbase Wallet®, the extension gives users full control of their crypto while making it easy to connect to decentralized apps (dapps), NFTs, and Web3 services. This guide walks you through the basics of getting started, from installation to everyday use.
What Is the Coinbase Extension?
The Coinbase Extension is a self-custody wallet, meaning you—not Coinbase—control your private keys and funds. Unlike a centralized exchange account, the wallet operates independently and allows you to interact directly with blockchain networks such as Ethereum, Polygon, and others. The extension is designed for convenience, enabling secure access to crypto assets and Web3 experiences right from your browser.
Installing the Extension
To get started, install the Coinbase Extension from your browser’s official extension store (such as Chrome Web Store). Once installed, the Coinbase Wallet icon will appear in your browser toolbar. Clicking it opens the wallet interface, where you can either create a new wallet or import an existing one.
Creating or Importing a Wallet
When setting up the extension, you’ll have two options:
- Create a new wallet: This generates a brand-new wallet with a unique recovery phrase.
- Import an existing wallet: If you already use Coinbase Wallet on mobile or another wallet provider, you can restore access using your recovery phrase.
During setup, you’ll be shown a 12-word recovery phrase. This phrase is the only way to recover your wallet if you lose access to your device. Store it securely offline and never share it with anyone.
Securing Your Wallet
After setup, you’ll create a password to protect the extension on your device. This password adds a layer of security but does not replace your recovery phrase. For additional protection, enable features such as auto-lock timers and biometric authentication (if supported by your system).
Because the Coinbase Extension is a self-custody wallet, Coinbase cannot recover lost passwords or phrases. Security is entirely in your hands, so taking these steps seriously is essential.
Adding and Managing Assets
Once your wallet is set up, you can start adding crypto assets. The extension supports a wide range of tokens across multiple networks. You can receive funds by copying your wallet address or using a QR code. Sending crypto is just as simple—enter the recipient’s address, choose the amount, and confirm the transaction.
The wallet also allows you to switch between networks easily, making it straightforward to manage assets on different blockchains from one interface.
Connecting to dapps and Web3
One of the key benefits of the Coinbase Extension is seamless access to decentralized applications. When visiting a supported dapp—such as an NFT marketplace or DeFi platform—you can connect your wallet with a single click. The extension will prompt you to approve connections and transactions, giving you full visibility and control over what you’re authorizing.
This makes activities like swapping tokens, staking assets, or buying NFTs fast and secure without leaving your browser.
NFTs and Digital Collectibles
The Coinbase Extension includes built-in NFT support, allowing you to view, send, and receive NFTs directly in your wallet. Your collectibles are displayed visually, making it easy to manage your digital assets without relying on third-party tools.
Transaction Fees and Network Costs
While the extension itself is free to use, blockchain transactions require network fees (often called gas fees). These fees are paid to the blockchain network, not Coinbase, and can vary depending on network congestion. The wallet shows estimated fees before you confirm any transaction so you can make informed decisions.
Keeping Your Wallet Updated
Coinbase regularly releases updates to improve security, performance, and compatibility with new networks and dapps. Keeping your browser and extension up to date ensures you have access to the latest features and protections.
Final Thoughts
The Coinbase Extension® offers a powerful yet user-friendly way to explore crypto and Web3 from your desktop. By combining self-custody, strong security features, and seamless dapp integration, it’s well suited for both beginners and experienced crypto users. As long as you protect your recovery phrase and stay mindful of permissions, the extension provides a safe and flexible gateway into the decentralized web.
