Coinbase Wallet extension: frequently asked questions

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.

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.

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.

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.

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.

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.

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.

The extension itself is a legitimate, widely used wallet, but self-custody means the security decisions are yours. The two biggest risks are phishing — fake extension listings and lookalike websites that ask for your recovery phrase — and a compromised computer. Install only from the official source and treat your 12-word phrase like the key to a safe deposit box.

Coinbase Wallet focuses on Ethereum and other EVM-compatible networks, and Coinbase has added further networks over time, including Solana. The exact list of supported assets grows and changes, so check the official Coinbase Wallet documentation for what is supported today.

Browser extensions are desktop-only, since mobile browsers do not run them. On a phone you use the Coinbase Wallet mobile app instead, and you can pair the app with desktop sites by scanning a WalletConnect QR code.

Coinbase Wallet supports connecting certain hardware wallets so that transaction approvals happen on the device rather than in the extension — the strongest setup if you hold larger amounts. Hardware support depends on the wallet model, so confirm current compatibility in the official documentation.

Most problems are solved by unlocking the wallet, reloading the page, checking that the extension is enabled in your browser, and confirming the site is asking the right network. Our troubleshooting page walks through the common fixes in order, and the official Coinbase Wallet help centre covers account-specific issues.

No. This is an independent educational guide to how the extension works and how to use it safely. It is not affiliated with Coinbase, and nothing here is financial, tax or legal advice.
