Coinbase Wallet Extension
The Coinbase Wallet extension is a self-custody crypto wallet that lives in your desktop browser. It keeps your keys on your own device, holds your tokens and NFTs, and lets Web3 apps ask you to approve each transaction. This guide explains what it does, how to install it safely, and how to avoid the scams that target browser wallets.

The basics
What the Coinbase Wallet extension actually is
The extension is a browser add-on built by Coinbase that adds a wallet to your desktop browser. Once it is installed and unlocked, it can hold crypto, show your balances, sign transactions and connect to decentralized applications (dApps) on the open web. Think of it as the desktop counterpart to the Coinbase Wallet mobile app: the same self-custody idea, wrapped in a browser panel instead of a phone screen.
Self-custody is the part worth understanding. When you set the wallet up, it generates a private key and a 12-word recovery phrase on your device. Those are encrypted with a password you choose and are never handed to Coinbase. In practice that means nobody at Coinbase can move your funds, freeze them or restore your wallet for you — the trade-off for full control is that the recovery phrase is your only backup.
That is different from a Coinbase exchange account, where Coinbase holds the assets on your behalf and you sign in with an email address, password and two-factor code. Most people end up using both: the account for buying and selling, the extension for connecting to Web3 apps. Our comparison of the extension and the exchange account explains where each one fits.
| Coinbase Wallet extension | Coinbase exchange account | |
|---|---|---|
| Who holds the keys | You, on your device | Coinbase, on your behalf |
| How you sign in | A password on that browser plus your recovery phrase as backup | Email, password and two-factor authentication |
| Who can recover funds | Only you, using the recovery phrase | Coinbase support, within its own rules |
| Best for | dApps, tokens, NFTs, on-chain activity | Buying, selling and holding with a familiar interface |
In one sentence
A browser add-on that keeps your crypto keys on your own device and lets websites ask you to approve transactions — with no custodian standing behind it.Use cases
What you can do with it in a normal browsing session
Hold and send tokens
Keep balances in a wallet you control, view activity, and send funds to any address or ENS name. Every transfer is confirmed by you first.
Swap between assets
Trade one token for another without leaving the wallet, with the route and network fee shown before you approve.
Connect to dApps
Use DeFi dashboards, marketplaces and games by connecting your wallet instead of creating yet another username and password.
Manage NFTs
View the collectibles held by your address, see their details, and move them to another wallet when you need to.
Move between networks
Switch between Ethereum and other supported networks so you can use apps on the chain they run on.
Link your Coinbase account
Optionally connect a Coinbase account so buying, selling and moving funds between the two is a couple of clicks rather than a manual transfer.

How it works
From install to first transaction in four moves
- 1
Install it from the official source
Add the extension to a Chromium-based browser from the official Coinbase Wallet page — never from a sponsored search result or an advert, which is where counterfeit listings live.
Step-by-step installation guide → - 2
Create a new wallet or import one
A new wallet generates a fresh recovery phrase. Importing an existing phrase gives this browser the same funds as your other wallet — only do that on a computer you trust.
- 3
Write the recovery phrase down offline
Twelve words, written by hand, stored somewhere a burglar and a hacker both cannot reach. No screenshots, no cloud notes, no email to yourself.

Fund it and connect your first dApp
Send a small test amount first and confirm it arrives before moving anything larger. Then connect to a site you trust and approve the transaction when it looks right.
Security essentials
Four habits that prevent almost every loss
- Never type your recovery phrase into a website, chat or form. No legitimate service ever asks for it.
- Install only from the official listing. Bookmark the official Coinbase Wallet page and use it every time.
- Check what you approve. Read the network, amount and recipient in the confirmation window before you sign.
- Keep the device clean. A computer full of pirated software and sketchy extensions is not a safe place for keys.
The full security guide covers phishing patterns, token approvals, and what to do if you think a wallet has been exposed.
The one rule that matters most
Whoever holds the 12 words holds the money. Anyone who asks you for them — support agent, giveaway, “wallet validation” page, friend in a hurry — is trying to empty your wallet.What the wallet protects, and what it cannot
The extension encrypts your keys behind a local password and keeps them inside the extension rather than on the open web. It cannot protect you from approving a malicious transaction, from a phishing site that imitates a real one, or from malware already running on your computer.
When something goes wrong
Common problems, in order of how often they happen
A site says no wallet detected
Usually the extension is locked, disabled, or the page was loaded before the wallet was ready. Unlock, reload, and check the site is on the network you are connected to.
The icon has disappeared
Browsers hide or disable extensions after updates and profile changes. Check the extensions page and pin the wallet back to the toolbar.
A transaction is stuck
A pending transaction is a network fee problem rather than a wallet problem — look at the explorer, wait, or replace it with a higher fee from the wallet.
Questions
Coinbase Wallet extension FAQ
What is the Coinbase Wallet extension?
It is a free browser add-on from Coinbase that puts a self-custody crypto wallet inside your desktop browser. It holds your private keys on your own device, so you approve transactions yourself instead of Coinbase holding the funds for you. It is a different product from a Coinbase exchange account, where Coinbase holds the assets.
Is the Coinbase Wallet extension free to use?
Installing and using the extension costs nothing. You still pay blockchain network fees (gas) on the transactions you send, and Coinbase may charge a fee or spread when you buy crypto with a card or bank transfer inside the wallet. There is no subscription.
Is the Coinbase Wallet extension the same as my Coinbase account?
No. A Coinbase exchange account is custodial: you sign in with an email address and password, and Coinbase holds the assets for you. Coinbase Wallet is self-custody: your keys live on your device and only you can move the funds. You can link the two so it is easy to move crypto between them, but they are separate products with separate support paths.
Which browsers support the Coinbase Wallet extension?
It is built for Chromium-based desktop browsers, which includes Google Chrome, Brave, Microsoft Edge and Opera. Support lists do change, so check the official Coinbase Wallet page before assuming a particular browser version is supported.
Can I import an existing wallet instead of creating a new one?
Yes. When you first open the extension you can either create a brand new wallet, which generates a new recovery phrase, or import a wallet you already own by entering its 12-word recovery phrase. Importing gives the extension access to the same on-chain funds as your other wallet, so only do it on a device you trust.
Where is my recovery phrase stored?
Only on your device, encrypted behind the password you set, and anywhere you deliberately wrote it down. Coinbase does not keep a copy, so nobody at Coinbase can restore your wallet. If you lose the device and the phrase, the funds in that wallet are permanently unreachable.
Why does the extension ask for permission to connect to a website?
Connecting a site shares your public wallet address and lets that site ask you to sign transactions. It never hands over your private keys, and every transaction still needs your approval. You can disconnect a site at any time from the wallet's connected-apps list.
