Core wallet extension install and download guide
Open the Chrome Web Store directly from your browser. Search for the official plugin maintained by the Core team. This is the only verified source. Avoid third-party sites offering the firefox extension or brave extension as they often host outdated or malicious code. For Chrome, look for the listing with over 1 million users and the blue verified publisher badge. For Edge, the process is identical–the Microsoft Edge Add-ons store mirrors the Chrome Web Store version, but always confirm the publisher name matches the parent company exactly.
Never use a direct ZIP download from a random GitHub repository or forum link. Legitimate firefox extension releases are exclusively listed on the Firefox Browser Add-ons portal. If you need the brave extension, open Brave’s built-in store or install it through the Chrome Web Store since Brave is Chromium-based. The plugin for Opera or Vivaldi follows the same dependency. A single misstep in the for edge or for chrome selection can expose your seed phrase to clipboard hijackers.
After you complete the initial setup, immediately test the browser integration by refreshing any decentralized application page. The prompt to connect should appear without errors. If the plugin fails to load, reinstall from the official source–do not patch it manually. The recommended sequence: for chrome, add to Chrome; for edge, get from Edge Add-ons; for Firefox, grab the firefox extension; and for Brave, use the Chrome Web Store as a brave extension fallback.
Core Wallet Extension Install and Download Guide
Open the Chrome Web Store directly in your browser and search for the Brave extension that matches the „Core“ suite you want. For Chrome users, the fastest method is to type `chrome:extensions` into the address bar and then toggle „Developer mode“ on before dragging the CRX file from your downloads folder. Do not use the Firefox extension unless you are on a Firefox-based browser; the plugin architecture differs significantly and the Brave extension version may have slightly different naming in the store. To get the plugin for Chrome, navigate to the Chrome Web Store homepage and use the search bar with the exact name of the product. Once located, click „Add to Chrome“ and confirm the permission popup–this triggers the actual download chrome process, which pulls the package from the store servers. For Firefox, visit the Firefox Browser Add-ons portal and search for the same plugin; the install procedure here requires a single click on „Add to Firefox.“ If you prefer a manual method, visit the official repository (typically GitHub) to download chrome the CRX or XPI file directly. For Chrome, open the Extensions page via `chrome:extensions/`, enable „Developer mode,“ drag the downloaded CRX file into the window, and click „Add extension.“ For Firefox, you can drag the XPI file onto the browser window or use the gear menu to „Install Add-on From File.“
After completing the initial install for chrome, check the browser toolbar–look for a puzzle piece icon or the specific button of the Brave extension. If you do not see it, click the puzzle piece icon in Chrome’s toolbar, find the plugin in the list, and pin it to the toolbar for quick access. In Firefox, this option appears under the extensions icon in the address bar.
Verifying the plugin’s correct setup is critical: open a new tab and type `chrome:extensions/` (or `about:addons` for Firefox). Locate the Brave extension entry and ensure there is no error message under „Errors.“ If you see a yellow warning triangle, the plugin may be missing a required permission–click „Details“ and grant all requested access. Should you encounter a „This extension may have been corrupted“ warning during the download chrome process, delete the file immediately and obtain a fresh copy from the Chrome Web Store only. Avoid third-party sites that offer a version of the Brave extension for Chrome; these often contain adware that piggybacks on the plugin code. For enterprise users managing multiple devices, the plugin can be deployed via group policy for Chrome or through the Firefox private network API. Use the Chrome Web Store item ID (a 32-character string in the URL) to push the Brave extension silently to all browsers in your organization. The Firefox extension equivalent uses a similar UUID for forced installation. After you have the plugin running, test it by visiting a site that requires the plugin’s functionality–if the page does not load or prompts you to re-install, return to the Extensions page and toggle the plugin off and on again. This refreshes the connection between the browser and the Brave extension without needing a full download chrome repeat. Q&A: I downloaded the Core wallet extension file, but my browser says it can't install it because it's from an unknown source. How do I make it work? This usually happens because your browser blocks extensions not from its official store. The safest method is to install Core directly from the Chrome Web Store (or your browser's equivalent) rather than using the downloaded file. If you still need to install from a file (for example, an offline version), you must enable „Developer mode“ in your browser's extension management settings (chrome:extensions). Then, drag and drop the downloaded .crx or .zip file onto that page. Be careful with this method—only use files from the official Core website or a trusted GitHub repository to avoid malicious software.
Is the Core wallet extension safe to download, and how do I verify I’m getting the real one from Avalanche and not a fake copy?
Safety is the main concern here. The standard way to install the Core wallet is through your browser’s official extension store—like the Chrome Web Store or the Firefox Add-ons site. In the search bar of that store, type „Core wallet“ by Avalanche. Look for the publisher name: it should be „Ava Labs“ or directly related to „Avalanche.“ Also check the number of users and reviews; a legitimate extension will have a high number of installations and consistent positive feedback. Avoid downloading Core from random websites, Google search ads, or direct links sent by strangers. The official version does not ask for your seed phrase in any pop-up window during installation. If a page asks you to enter your recovery phrase upon setup, you are on a phishing site.
I installed the Core extension, but it keeps asking me to „connect“ to my wallet. It also won’t show my balances. What am I doing wrong?
This is a common point of confusion. Installing the Core extension is only the first step; you also need to create or import a wallet profile inside that extension. After you install it, click the puzzle piece icon in your browser toolbar, pin the Core extension, and open it. You will see a screen asking you to either „Create a new wallet“ or „Import an existing wallet.“ Choose „Create“ to generate a new seed phrase and wallet address. Until you finish that setup process, the extension is like an empty container—it has no accounts, so it cannot show balances or allow transactions. Once you set up your wallet profile, the balances of AVAX and any assets on the Avalanche C-Chain will appear automatically. If they do not, check that you are on the correct network inside the extension settings.
Does the Core wallet extension work with Ledger hardware wallets for cold storage, or is it only for hot wallets?
Yes, it works with Ledger devices, but you need to follow a specific setup. First, install the Core extension normally. Instead of clicking „Create a new wallet,“ look for an option that says „Connect Hardware Wallet“ or „Ledger.“ You need to have the Avalanche app installed on your Ledger device (check Ledger Live for that). Connect your Ledger via USB, unlock it, and open the Avalanche app. In the Core extension, choose the Ledger option, and it will ask you to select the account addresses from the hardware device. Your funds remain on the Ledger’s secure chip; the Core extension only acts as a screen to display balances and to send transactions that you must physically confirm on the Ledger. Without that confirmation, no coins can leave your cold storage.
I’m on a corporate or school laptop and the admin blocks Chrome Web Store downloads. Can I still use the Core wallet extension through a different method?
If your system administrator has blocked access to browser extension stores, you have limited options. The safest path is to talk to your IT department and ask for an exception. Installing the extension manually via a .crx file (from an unofficial source) is not recommended, because that file could be tampered with. A workaround is to use the web-based version of Core at app.core.app (formerly known as the Core web wallet). This site works directly in your browser without needing a downloadable extension. You can connect a hardware wallet like Ledger to this site, or import a wallet using a seed phrase. Just be aware that you must fully trust the device you are using, as web wallets are more exposed to keyloggers and malware than the extension version. For regular browsing on a restricted computer, consider using a personal smartphone as your primary wallet instead.
After installing the Core extension, my browser is slower and it asks for permissions to „read and change data on all websites.“ Why does it need that, and can I block it?
That permission request is standard for almost all browser-based crypto wallet extensions (MetaMask, Phantom, etc.). Core Wallet import wallet needs it to inject a script (a small piece of code) into any webpage so that the website can detect your wallet. For example, when you go to a dApp like Trader Joe or Pangolin, the dApp reads the Core injection to know your address and to trigger a transaction popup. Without that permission, the dApp cannot connect to your wallet. If you deny this permission during installation, the extension will not function. However, Core should not be „reading“ your personal data like emails or banking pages—the permission is technically broad, but the extension only activates its injection on websites that specifically interact with Avalanche smart contracts. If you notice a slowdown, try disabling the extension on sites you do not use for crypto. You can right-click the Core icon and select „This can read and change site data“ and choose „On click“ instead of „On all sites“ to limit its activity.
