The basics
What is the Coinbase Extension?
A quick, jargon-free introduction to the wallet and what it actually does.
The Coinbase extension — officially called the Coinbase Wallet browser extension — is a self-custody (non-custodial) crypto wallet that lives right inside your web browser. Instead of trusting a third party to hold your crypto, a self-custody wallet gives you direct control: you hold the private keys and the 12-word recovery phrase.
With the extension installed, you can store and send crypto, connect to decentralized apps (dapps), use decentralized exchanges and DeFi protocols, collect and view NFTs, and approve transactions — all without leaving your browser. It's designed to be the on-ramp to the "open web" of crypto.
Note that the Coinbase extension is not the same as Coinbase Exchange. The exchange is a custodial platform, while Coinbase Wallet is a separate, self-custody product where you own your keys.
- Holds Ethereum, Base, Solana and many other supported assets
- Connects to dapps, DeFi platforms and NFT marketplaces
- Lets you approve or sign transactions directly from the browser
- Pairs with the Coinbase Wallet mobile app for cross-device use

Setup
How to Install the Coinbase Extension Safely
Follow these steps and, most importantly, only download from official sources.
Go to the official source
Visit the official Coinbase Wallet page (coinbase.com/wallet) or the official Chrome Web Store listing.
Verify the publisher
In the Chrome Web Store, confirm the extension is published by Coinbase (Toshi Holdings) before adding it — scammers publish look-alike extensions.
Click "Add to Chrome"
Add the extension to your browser, then pin it to the toolbar using the puzzle-piece icon for quick access.
Create or import a wallet
Choose "Create new wallet" and safely write down your 12-word recovery phrase, or "Import wallet" if you already have a Coinbase Wallet.
Set a strong password
Create a strong, unique password that protects the wallet on this device. Then you're ready to explore dapps and manage your crypto.
⚠️
Never share your recovery phrase
Your 12-word recovery phrase is the master key to your wallet. Coinbase (and no legitimate support team) will ever ask for it. Anyone who asks for your phrase is trying to steal your funds. Write it down offline, keep it private, and store it somewhere safe.
💡 Tip: Bookmark the official page and always navigate to it directly. Avoid clicking wallet-download links from unsolicited messages, ads or social media posts, which are common phishing vectors.
Stay safe
Coinbase Extension Security Best Practices
Self-custody means great control and great responsibility. These habits keep your wallet safe.
- Only install the extension from the official Coinbase website or the verified Chrome Web Store listing
- Write your 12-word recovery phrase on paper and store it offline — never in cloud notes or screenshots
- Use a strong, unique password and enable additional device security (screen lock, 2FA where available)
- Double-check every transaction and dapp approval before signing
- Be wary of "wallet connect" prompts on unfamiliar websites — verify the URL first
- Keep your browser and operating system updated to reduce malware risk
FAQ
Coinbase Extension — Frequently Asked Questions
Quick answers to the questions people ask most about the Coinbase Wallet browser extension.
What is the Coinbase extension?
The Coinbase extension is the Coinbase Wallet browser extension — a self-custody crypto wallet that runs in Chrome and other Chromium-based browsers. It lets you store and send crypto, connect to dapps and DeFi, and manage NFTs, all while keeping control of your own keys.
Is the Coinbase Wallet extension free?
Yes. Downloading and using the Coinbase Wallet extension is free. You may still pay standard network (gas) fees when sending or swapping crypto on-chain — those go to the network, not to Coinbase Wallet.
Is the Coinbase extension safe?
Coinbase Wallet is a reputable self-custody wallet, but your safety largely depends on your own habits. Only install it from the official Coinbase site or the official Chrome Web Store listing, and never share your 12-word recovery phrase with anyone.
Which networks does the Coinbase extension support?
It supports Ethereum, Base, Solana, Arbitrum, Optimism, Polygon and many other EVM and multi-chain networks, so you can manage a wide range of assets from a single wallet.
Is the Coinbase extension the same as Coinbase Exchange?
No. Coinbase Wallet (the extension) is a self-custody wallet where you control your own keys. Coinbase Exchange is a custodial platform where Coinbase holds assets on your behalf. They are separate products.
Can I recover my Coinbase Wallet if I lose access?
Yes — as long as you have your 12-word recovery phrase. You can import the same phrase into a fresh Coinbase Wallet to restore access. If you lose the phrase, the wallet generally cannot be recovered, which is why secure offline storage matters.
