Install and download core wallet extension



Install and download core wallet extension

Use the official Brave plugin if your browser is Brave. For Firefox users, the Firefox extension integrated directly into the browser’s add-on manager. Avoid third-party clones. Always verify the publisher name matches the project’s official GitHub repository.


For those using Chrome or Brave, the path is identical: open the Chrome Web Store and search for the plugin by its verified developer name. Do not fall for promoted ads or sponsored results. The Chrome web store listing shows a blue “Add to Chrome” button; pressing this installs the add-on into your browser’s toolbar instantly. The same button works for download Chrome and brave extension installations–both use the Chromium engine.


Firefox users must go to the Mozilla Add-ons site, not the Chrome web store. The Firefox extension file is a single XPI package. Click “Add to Firefox” and authorize the permissions. No additional software is required; your browser handles the full setup. The plugin will appear in the upper-right corner of the interface post-deployment.


If you require a portable version or an offline backup, download the CRX file from the publisher’s official site, then drag it onto the browser extensions page (chrome://extensions). Enable “Developer mode” first to load unpacked or crx files. This method bypasses the store entirely, useful for air-gapped machines or strict network environments.

Install and Download Core Wallet Extension

To acquire the Core application for your web navigator, begin by opening a new tab in your browser and going straight to the official Core DAO website. The sole secure method to download chrome’s version is through the Chrome Web Store listing. Any other source poses a risk of malware. Locate the "Add to Chrome" button–this action initiates the process to install the plugin into your specific browser.


If you are a user of Mozilla’s software, select the firefox extension option from the same official site. The process is identical: click the permit button, and the add-on will integrate seamlessly into your browser. Note that the firefox extension often receives feature updates a day later than the Chrome version due to Mozilla’s review queue.


Navigate to the official Core Wallet import wallet DAO webpage.
Click the download link that matches your operating system (Windows, macOS, Linux).
For Edge users, pick the brave extension or for edge link, which redirects to the Chromium Web Store–Edge is Chromium-based, so it accepts the same package. Brave extension compatibility is identical.


After the download finishes, a pop-up window will appear asking for permission. Grant it. The plugin icon will appear in your toolbar–typically a circular symbol. Click this icon to open the setup wizard. Do not close the browser tab until the process confirms the plugin is active. A common mistake is switching tabs during the final 10-second verification step, which can corrupt the installation.


Use download chrome only if you run the Chrome navigator. For Opera or Vivaldi, the same download chrome package works.
Select for edge if you rely on Microsoft’s navigator; the download source is the same Edge Add-ons store.
For Brave users, the brave extension link is redundant unless you prefer direct installation from Brave’s own store–functionality is identical.


Post-installation, create a new secure phrase. Write it on paper–never store it digitally. The plugin will then prompt you to set a password. Use 12+ characters mixing symbols and numbers. Without this, the download is useless. After completing the setup, test the plugin by connecting to a testnet dApp to verify functionality. Reboot your browser if the icon fails to respond.


Firefox extension users must ensure their browser version is 115 or higher. Older versions lack the WebExtensions API required. Similarly, the for edge route demands Edge version 100+. To confirm success, check the plugin’s settings menu–it should display your wallet address. If the address field is empty, delete the download and repeat the process from scratch. Do not rely on backup extensions; each install must be independent.

Verify the Official Download Source for Your Browser

Always initiate the process directly from the official storefront for your specific browser. For chrome, this is exclusively the chrome web store. Any site prompting you to download chrome software from a third-party page is a phishing attempt. The only authoritative repository for a chrome web store listing is Chrome.google.com/webstore.


For a firefox extension, the sole legitimate source is Mozilla’s own Add-ons site (addons.mozilla.org). If a webpage instructs you to "save file" or run an executable to get a firefox extension, stop immediately. Mozilla enforces strict review policies; anything outside their marketplace bypasses security scanning and likely contains malware, particularly for crypto-related plugins.


On Microsoft edge, the only safe repository is the Edge Add-ons website. Microsoft Edge users must navigate to the official Add-ons page within the browser’s settings menu (edge://extensions) or use the store inside the browser. Never accept a "one-click plugin" offer from a pop-up ad or a search result claiming to be a "faster" chrome web store mirror–those are fraudulent.


Searching for a brave extension requires extra caution because Brave Browser defaults to the chrome web store for its add-ons. However, Brave also has its own curated list on its official website. Scammers frequently target Brave users by creating fake pages that mimic the official store. Confirm the URL starts with "chrome.google.com" before you proceed.


A common attack vector uses deceptive search ads. If you type "download chrome [product name]" and click the first result, it may lead to a page pretenting to be the store but hosting a malicious plugin. Verify the domain in the address bar: the real chrome web store URL contains "chrome.google.com/webstore" and nothing else. Any variation is a fake.


Legitimate browser stores never ask you to disable antivirus or grant permissions to a website. When you locate a firefox extension or a brave extension, check its publisher name, number of downloads, and review ratings directly on the store page. A new listing with zero ratings and mismatched developer names is a red flag, even if the plugin appears on a seemingly correct domain.


Finally, use your browser's built-in extension manager to search for the add-on. For chrome and edge, type "chrome://extensions" or "edge://extensions" into the address bar and click "Get more extensions" to reach the official store. This guarantees you bypass fake websites entirely. Never trust a third-party site that offers a direct plugin file for download; only the official storefront provides a secure acquisition channel.

Q&A:
Is it safe to download a core wallet extension from a third-party website, or should I only use the official project site?

You should always download a core wallet extension from the official project website or a trusted, verified source like the official browser extension store (e.g., Chrome Web Store, Firefox Add-ons). Third-party websites can host modified versions that include malware or phishing scripts designed to steal your private keys. Even a slightly altered version might look identical but could send your transactions to a different address. Most projects list their official download links on their GitHub repository or main page. If you use a third-party site, check the extension's developer name against the project's official announcement and read recent user reviews to spot warnings about fake copies. Switching sources just because a site looks cleaner might cost you access to your funds.

I downloaded a core wallet extension, but my browser says it can “read and change data on all websites.” Why does it need that permission? Is it dangerous?

That permission request is common for browser wallet extensions, and it often worries new users. The extension needs this access to interact with decentralized applications (dApps) that run in your browser. For example, when you visit a swapping site like Uniswap, the extension must read the page to detect a connection request and then inject a “Connect Wallet” button. It also needs to modify the page temporarily to show transaction confirmation pop-ups. However, this permission does mean a malicious extension could read your passwords or bank pages. That is why caution is required. A legitimate core wallet extension like MetaMask or Ronin Wallet does not collect or send your browsing data; it only acts when you click on it or when a dApp requests a signature. To stay safe, only install extensions that are open-source and well-audited. You can revoke permissions later in your browser settings if you stop using the extension.

How do I move my wallet from a desktop software client to a browser extension without losing my coins? I have a backup phrase from the desktop app.

If you have the 12- or 24-word recovery phrase (seed phrase) from your desktop wallet, you can restore it directly into the browser extension. Start by installing the core wallet extension from the official source. Then, instead of choosing “Create a new wallet,” select “Import wallet” or “Restore using seed phrase.” Enter your existing recovery phrase exactly as it is written, with the same order and spelling. The extension will generate the same private keys locally on your device, so your balances and transaction history will appear. Your coins never leave the blockchain; only the access tool changes. Do not lose that seed phrase—do not take a screenshot or store it in a cloud text file. If you prefer not to re-enter the phrase on a computer you think might be infected, you can send a small test transaction to the extension's new address first. That way, you only risk a small amount to confirm the setup works correctly.

After installing the core wallet extension, my computer slowed down a lot. Is this normal, and what can I do to fix it?

It is not normal for a wallet extension to significantly slow down your entire system. Wallet extensions are generally lightweight; they are just storing keys and signing transactions. If your computer becomes sluggish after installation, the problem is usually one of three things. First, some extensions have a bug that causes them to keep trying to connect to the network in a loop, using too much CPU. Check your browser's task manager (Shift+Esc in Chrome) to see the extension's memory and CPU usage. Second, you might have downloaded a fake extension that runs hidden cryptocurrency mining scripts in the background; remove it immediately. Third, the extension could be conflicting with another add-on, such as an older wallet or a privacy blocker. Try disabling other extensions one by one. If the issue continues, uninstall the core wallet extension, reboot your computer, and reinstall it from the official source. If it still lags, try a different browser. A correctly installed extension should use less than 100MB of RAM and barely show in the CPU column when idle.
