Install and download core wallet extension
Install and download core wallet extension
You need the plugin for your browser. Open the Chrome Web Store directly from your Chrome browser, or use the equivalent storefront for Edge or Brave. Search for the official Core software–do not select any third-party copy. For Edge users, the same Chrome Web Store listing works seamlessly; Brave users can also integrate it via their Web3-ready browser. Avoid any pop-ups offering a fast download from an external site; always proceed through the official store.
For Firefox users, a dedicated Firefox extension is available on Mozilla’s add-ons portal. This version is optimized for Firefox’s architecture and does not rely on the Chrome Web Store. If you prefer a Chromium-based environment, installing the plugin for Chrome or for Edge ensures full compatibility with decentralized applications. The Brave extension will function identically once added from the Chrome Web Store, as Brave is built on Chromium. Always verify the publisher is verified and review the permission requests before adding any plugin to your browser.
Do not download a separate installer file from any website claiming to offer a faster setup. The only safe method is to add the plugin through your browser’s official extension market. After confirming the listing, click “Add to [Browser].” The system will prompt you to review required permissions, such as access to website data for transaction signing. Once added, the plugin icon appears near your address bar. For Edge and Brave, the process mirrors the Chrome Web Store procedure, requiring no extra steps. Avoid using generic search results; type “Chrome Web Store Core plugin” directly into your address bar.
Install and Download Core Wallet Extension
For a direct setup, acquire the Core plugin exclusively through the chrome web store if you use Google Chrome or a Chromium-based browser. Open your browser, navigate to the store, and search for "Avalanche Core" by Ava Labs. Click "Add to Chrome" and confirm the permission prompt–this triggers a silent background setup, with the icon appearing on your toolbar. For brave extension support or for edge deployment, the same store link works seamlessly, as both browsers are Chromium-based. Avoid third-party sites entirely; only the official store listing guarantees a secure, signed copy. The plugin itself is a self-contained binary, roughly 5-7 MB, and will auto-update via the browser’s background services.
For Firefox users: Open the firefox extension repository (addons.mozilla.org) and search for the same plugin–its architecture differs, but it offers identical functionality for managing tokens.
For Chrome or its derivatives: After the initial chrome web store fetch, the plugin requests network permissions for RPC endpoints; allow those to enable chain interactions.
Brave extension users: Ensure Shields are set to "Disable" for the store domain during setup–otherwise the fetch might be blocked.
Always verify the publisher: Only "Ava Labs" is legitimate. The plugin size must match the official release notes.
Do not skip the seed phrase step post-install–this is your sole recovery method; store it offline.
How to Verify the Official Download Source for Your Browser
Directly navigate to the Chrome Web Store by typing `chrome.google.com/webstore` into your address bar. For any plugin claiming to be a compatible tool, check that the publisher name matches the official project’s website. Avoid clicking sponsored search results; these often redirect to fraudulent copies designed to steal your data.
For users who prefer to work on a Brave browser, the process remains identical. Brave is built on Chromium, so it directly integrates with the Chrome Web Store. Pull up the store, search for the specific software, and scrutinize the “Offered by” field. If the developer’s name is a random string of letters or a misspelled version of the real project, it is a fake. Brave also checks all plugins against its built-in phishing filter, but this is not a substitute for your own verification.
When you download software optimized for Edge, do not use third-party aggregator sites. Microsoft Edge has its own dedicated add-ons marketplace. Go to `microsoftedge.microsoft.com/addons` to find the official listing. Double-check the “Version” history and the “Last updated” date. An infrequently updated add-on on Edge may indicate an abandoned copy that has no security patches. Always compare the number of user reviews against the official website’s traffic; a huge discrepancy signals a fraudulent page.
Never copy a download link from a random forum post. Even if a user claims to have checked the hash of a file, you cannot trust a shared hash. Instead, locate the official project repository on GitHub or the main product site. From that page, follow the direct link to the Chrome Web Store or the Firefox browser add-ons portal. This single step eliminates 99% of phishing attempts. If the official site points you to a “Get it on Firefox” button, click that button, not a search engine result.
To download Chrome-compatible software safely, use the exact URL from the official documentation. Open a new tab, paste that URL, and hit enter. Once the store page loads, verify the security badge: a green lock icon in the address bar. Also, examine the permissions list. Legitimate apps rarely ask for “Read and change all your data on all websites” unless they are a password manager or a VPN. If a simple utility demands that access, reject it immediately. For a Firefox extension, the same rules apply, though Mozilla’s review team typically flags overtly malicious code faster than Google’s.
Scammers often register domains that look identical to the official project name. For instance, a fake site named `your-project.io` might offer a direct download file ending in `.crx`. Never double-click a `.crx` file you found on a random website. Modern browsers block side-loaded plugins by default, and forcing the install via developer mode is a high-risk move. The only safe acquisition path is via the Chrome Web Store or the Firefox add-ons portal. If the source says “download the .crx here and drag it into your browser,” that is a red flag.
Cross-reference the developer’s email address listed in the store. A legitimate open-source project often has a support email tied to a verified domain, like `support@projectname.org`. Gmail or Protonmail addresses are suspicious unless the project is very new. Also, look for a published privacy policy. The Chrome Web Store requires a privacy policy for any plugin that handles user data. If the policy is a generic template or missing entirely, do not proceed. For a Brave extension, the same policy applies because Brave enforces Chromium’s store rules.
Finally, audit the permissions after the plugin is active. Go to your browser’s extension management page (type `chrome://extensions` in the address bar for Chrome or Edge, or `about:addons` for Firefox). Review the “Site access” settings. Set the add-on to “On click” if it does not need to run on every page. If you notice any unauthorized activity–like unexpected redirects or pop-ups–remove the plugin immediately. The official source is the only safe source; there are no exceptions for convenience.
Q&A:
Why can't I find the correct "core wallet" extension in the Chrome Web Store?
The most common reason is that the name "core wallet" is very generic and multiple apps might show up. Often, scammers create fake extensions with similar names to steal your funds. To find the right one, you need to search using the exact, official name of the blockchain’s wallet. For example, if you are looking for the Avalanche Core Wallet extension tutorial wallet, search for "Avalanche Core" (made by Ava Labs). Look at the publisher name and download count before clicking "Add to Chrome". A legitimate wallet extension from a major project will have thousands or millions of users and a clear website link in the description. If you are unsure, go directly to the official project website (like avalanche.org) and click the download link from there, as it will redirect you to the correct store page.
After downloading the extension, it says I need a "seed phrase". What happens if I lose my phone or computer after that?
That is the single most important part of the process. The seed phrase (usually 12 or 24 random words) is the master key to your wallet. If you lose your computer or phone, you will not lose your money. You will need to download the exact same wallet extension on a new device and choose the "Import wallet" option. You will then type in that exact seed phrase, and your entire wallet, including all balances and transaction history, will be restored. However, if you lose the seed phrase itself and then lose your device, your money is gone forever. There is no "forgot password" button for crypto wallets. Write the seed phrase down on paper and store it somewhere safe and offline (like a safe or a drawer at home). Never type it into a random website or take a photo of it with your phone.
I downloaded the extension, but my browser is telling me it can "read and change all your data on websites". Should I be worried?
Yes, that warning sounds scary, but it is standard for almost all crypto wallet extensions. The reason for this permission is that the wallet needs to interact with decentralized applications (dApps). For example, if you go to a trading website like Uniswap or OpenSea, the wallet extension needs to read the page's code to know how much you want to trade and then change the page to show a confirmation pop-up. It must also read the website address to prevent you from signing a transaction on a fake phishing site. Legitimate wallets only inject code when you click on the extension icon or visit a specific dApp. You should be worried only if the extension asks for this permission after you installed it, or if it has very few reviews. Always download from the official store to ensure this permission is used safely.
How do I actually set up the extension after I click "Install"? Do I need a hardware device first?
No, you do not need a hardware device to set up the extension. The installation process usually takes 2–3 minutes. After clicking "Add to Chrome", you will see a small fox or icon appear in the top right corner of your browser. Click that icon. The program will give you two options: "Create a new wallet" or "Import wallet". Choose "Create a new wallet". It will ask you to create a strong password (this is just for local access on your current browser). After that, it will show you your seed phrase. Write it down immediately. The final step is a confirmation test, where the extension will ask you to click on the words of your seed phrase in the correct order to prove you saved them. Once you pass that test, your wallet is active. You can add a hardware device (like a Ledger or Trezor) later for additional security for large amounts, but it is not required to receive or send small amounts of crypto.
