Coinbase Extension® — Getting Started | Coinbase®

The Coinbase Extension® is a browser-based crypto wallet designed to make interacting with decentralized applications (dApps), NFTs, and Web3 services simple and secure. Built by Coinbase®, the extension gives users direct control over their digital assets while staying connected to the broader Coinbase ecosystem.

This guide walks you through everything you need to know to get started with the Coinbase Extension®, from installation to everyday use, while highlighting essential security practices along the way.

What Is the Coinbase Extension®?

The Coinbase Extension® is a non-custodial crypto wallet that lives directly in your browser. Unlike centralized exchange wallets, it allows you to hold your own private keys, meaning you—not Coinbase®—control your crypto assets.

It supports popular blockchains such as Ethereum and other EVM-compatible networks, making it easy to interact with DeFi platforms, NFT marketplaces, and Web3 applications without leaving your browser.

Key features include:

Secure self-custody of digital assets

Seamless dApp and NFT interaction

Integration with the Coinbase® ecosystem

Simple interface for both beginners and experienced users

How the Coinbase Extension® Works

Once installed, the Coinbase Extension® acts as a bridge between your browser and blockchain-based applications. When you visit a supported dApp, the extension allows you to connect your wallet, approve transactions, and sign messages securely.

All sensitive actions—such as sending crypto or approving smart contracts—require your explicit confirmation. This design ensures transparency and prevents unauthorized access to your funds.

Because the wallet is non-custodial, your private keys are stored locally and protected by a password you create during setup.

Installing the Coinbase Extension®

Getting started with the Coinbase Extension® is straightforward:

Visit the official Coinbase® website or your browser’s extension store

Download and install the Coinbase Extension®

Open the extension from your browser toolbar

Choose to create a new wallet or import an existing one

During setup, you’ll be given a recovery phrase (also called a seed phrase). This phrase is critical—it is the only way to restore your wallet if you lose access to your device.

Important: Write the recovery phrase down and store it offline in a secure location. Never share it with anyone.

Creating or Importing a Wallet

When setting up the Coinbase Extension®, you have two options:

Create a New Wallet

This option is ideal for new users. The extension generates a new wallet and provides a recovery phrase unique to you.

Import an Existing Wallet

If you already have a crypto 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 set a strong password to protect access on your device.

Using the Coinbase Extension® Day to Day

Once your wallet is set up, you can start using the Coinbase Extension® immediately.

Common use cases include:

Sending and receiving cryptocurrencies

Connecting to decentralized exchanges (DEXs)

Managing NFTs

Approving smart contract transactions

Switching between supported networks

The extension clearly displays transaction details before you approve anything, helping you understand gas fees, network selection, and contract permissions.

Security Best Practices

While the Coinbase Extension® is built with strong security features, safe usage ultimately depends on the user.

To stay protected:

Never share your recovery phrase

Avoid installing fake or unofficial extensions

Double-check website URLs before connecting your wallet

Review transaction details carefully

Keep your browser and operating system up to date

Remember, because the wallet is self-custodial, you are fully responsible for your assets.

Coinbase Extension® vs. Exchange Wallets

One major difference between the Coinbase Extension® and a Coinbase® exchange account is custody. Exchange wallets are managed by Coinbase®, while the extension gives you full control over your private keys.

This makes the Coinbase Extension® ideal for users who want to explore DeFi, NFTs, and Web3 while maintaining ownership of their funds.

Who Should Use the Coinbase Extension®?

The Coinbase Extension® is well-suited for:

Beginners exploring Web3 for the first time

NFT collectors and traders

DeFi users who want a simple wallet interface

Coinbase® users seeking self-custody

Its balance of usability and control makes it a strong option for anyone looking to move beyond centralized platforms.
