Write this phrase down on paper using a pen. Do not store it in a digital file, screenshot, or cloud service. This is your master key; anyone who holds it controls your assets. The software will prompt you to confirm the phrase by selecting words in the correct order. Complete this verification without skipping any words.<br><br>To access existing holdings using a different software client, you must perform the import wallet procedure. Select the "restore from recovery phrase" option during the initial launch. Enter your 12 or 24-word sequence precisely, with spaces only between words and no trailing spaces. The application will scan the blockchain to find associated addresses. This process may take 10–30 minutes depending on network traffic.<br><br>For the tutorial on adding custom token networks, locate the network settings panel within the application interface. Enter the RPC URL, chain ID, and currency symbol provided by the blockchain explorer. Common values include chain ID 56 for BNB Smart Chain or chain ID 137 for Polygon. Save these settings and restart the application to enable transactions on that network.<br><br>A proper guide for securing your keys involves testing a small transaction first. Send $1 worth of tokens to the new address before moving larger sums. Verify the address matches exactly on the receiving device. Delete any test wallets once confirmed. Regularly update the application to obtain critical security patches that protect against newly discovered vulnerabilities.<br><br>Setup Core Wallet Extension Guide for Beginners<br><br>First, download the Core browser plugin exclusively from the Chrome Web Store or Brave Store to avoid phishing traps. After installation, pin the plugin to your toolbar by clicking the puzzle piece icon and selecting the pin symbol next to the Avalanche logo. Next, click the plugin icon and choose "Create a new wallet." The system will generate a 24-word secret phrase–write this on paper, never store it digitally or screenshot it. A hardware wallet like Ledger is safer for sums exceeding $1,000, but for quick testing, software storage suffices.<br><br><br>Create Wallet: Click the plugin, select "Create Wallet," then strongly record the 24-word mnemonic phrase on paper. Confirm three random words to verify your backup. This phrase is your only recovery method–losing it means permanent loss of funds.<br>Import Wallet: If you already have a private key or recovery phrase from another instance, click "Import Wallet" instead. Paste your mnemonic (12, 18, or 24 words) or raw private key (hex string). The plugin instantly restores your balances and transaction history.<br>Network Setup: By default, the plugin connects to Avalanche Mainnet. For test transactions, switch to Fuji Testnet via Settings > Networks. Fuji uses free fake AVAX from a faucet–useful for practicing swaps without real risk.<br><br><br>Open the Faucet link (e.g., https://faucet.avax.network) after switching to Fuji. Paste your X-Chain or C-Chain address (found under "Receive" in the plugin) and request test tokens. Wait 30 seconds, then refresh your balance. This tutorial step is mandatory for testing import or export operations before using real funds.<br><br><br>Security tip: Never interact with random dApps that request full wallet permissions. Use a separate browser profile for DeFi to reduce phishing risk. The plugin can be locked with a strong password–enable this under "Security & Privacy" immediately after creating the wallet.<br>Backup frequency: Re-verify your phrase every quarter by visiting Settings > Security > View Recovery Phrase. If you add new import wallet keys, note them separately. A single paper backup stored in a fireproof safe is sufficient for most users.<br><br><br>For advanced needs, click "Create Wallet" again to generate a hardened derivation path (e.g., m/44'/9000'/0'/0/0). This creates a subordinate account under the same mnemonic. Use this for separating personal funds from work tokens. The plugin supports up to 10 accounts per phrase–rename each under "Account Details" to avoid confusion during this tutorial.<br><br>Q&A:  <br>I downloaded a "core wallet" file from a website. Is that the same as the browser extension? How do I know which one is the real, safe version to install?<br><br>They are two different things. A "core wallet" is usually a full-node desktop program that downloads the entire blockchain to your computer. A wallet extension is a small browser add-on (like for Chrome or Firefox) that connects to a network but does not download the whole chain. For safety: never install a wallet from a random website link. Go directly to the official project website (for example, if it's for Bitcoin, go to bitcoin.org; for Ethereum, go to the official Ethereum site). Look for a "Wallet" or "Get Started" page that lists official browser extensions. Check the browser store ratings and the number of downloads. If the extension has less than 1,000 downloads or zero reviews, it is likely a fake. Only install from the official store page, not from a download link on a blog post.<br><br>I installed the extension and it gave me a 24-word seed phrase. I wrote it down on my computer in a text file. Is that safe enough?<br><br>No, storing your seed phrase as a text file on your computer is very risky. The seed phrase is the master key to every wallet the extension controls. If your computer gets a virus, spyware, or is hacked, that text file can be found and stolen immediately. A safer method: write the words down on paper with a pen. Use at least two separate pieces of paper. Store one in a fireproof safe or a locked drawer at home. Store the second one in a different secure location, like a bank safety deposit box. Do not take a photo of the paper with your phone, do not type it into cloud storage (Google Docs, iCloud, OneDrive), and do not email it to yourself. If you lose the paper, you lose your money. There are no recovery options for lost seed phrases.<br><br>My extension says I need to "create" or "import" a wallet. What is the difference? Which one should a beginner choose?<br><br>If you choose "Create a new wallet," the extension will generate a brand-new, unique seed phrase and wallet address for you. This is the safest option for a beginner because you know no one else has that seed phrase. You are starting fresh. The "Import" option is for people who already have a seed phrase from another wallet (for example, from an old hardware wallet or another app) and want to access that same account on this extension. As a beginner, you almost certainly want to choose "Create a new wallet." This gives you a fresh start and confirms you have control over the new seed phrase. Only use "Import" if you are deliberately moving an existing account.<br><br>After I set up the wallet, it shows a long string of letters and numbers. What is that? Do I need to hide it too, or just the seed phrase?<br><br>The long string is your public wallet address. You use it to receive money or tokens. It is safe to share this address publicly if you want to receive payments. For example, you can post it on a forum or show it on a website. The secret item is the seed phrase (the 12 or 24 words). That must never be shared with anyone. However, the wallet extension also has a "private key" associated with each address. You do not normally need to see or share your private key. As long as you have your seed phrase safely stored on paper, you have full control. Do not post your seed phrase online or give it to anyone who contacts you saying they are "support." No legitimate support person will ever ask for your seed phrase or private key.<br><br>I set up the extension but I can't see any balance. How do I actually put money into it? I don't see a "buy" button.<br><br>Most basic wallet extensions do not have a "buy" button. They are just tools for sending and receiving. To put money into your new wallet, you need to get cryptocurrency from someplace else first. For example: 1) You can buy Bitcoin or Ether on a regulated exchange (like Coinbase, Kraken, or Binance) using a bank transfer or credit card. 2) After you buy it on the exchange, you go to the "Withdraw" or "Send" section of that exchange. 3) You copy your wallet address from the extension (the long string of letters and numbers). 4) You paste that address into the exchange's send field, type the amount, and confirm. The exchange will send the coins to your wallet. The transaction takes a few minutes to several hours depending on network traffic. Once it is confirmed, your balance in the extension will update automatically.<br>
