img width: 750px; iframe.movie width: 750px; height: 450px; Portal wallet extension setup and usage guide Portal wallet extension setup and usage guide Download the ZIP archive from the official GitHub releases page, verify the SHA-256 checksum against the published hash, and unpack it to a dedicated directory. Open Chromium-based browsers (Chrome, Brave, Edge) and navigate to chrome://extensions; enable "Developer mode" via the toggle in the top-right corner. Click "Load unpacked" and select the unzipped folder. The application icon will appear in the toolbar. Pin it for immediate access via the puzzle-piece icon menu. On first launch, click the icon and select "Create new identity." The system generates a 12-word mnemonic phrase displayed in a single read-only window. Copy these words onto a paper document using a physical pen–never store them in a cloud or screenshot them. Confirm three random words from the sequence to finalize creation. The interface then shows your receiving address (a 42-character hexadecimal string starting with "0x") and an encrypted keystore file prompt. Back up this keystore file to an encrypted USB drive labelled with the date. For token operations, click "Send" and paste the destination address; the gas estimator automatically pulls current network fees via the integrated Ethereum RPC endpoint (default mainnet URL: https://eth-mainnet.g.alchemy.com/v2/your-api-key). Replace the placeholder with your personal Alchemy or Infura endpoint for non-custodial control. The "Settings" tab allows you to switch networks–Sepolia for testing (chain ID 11155111) or Arbitrum One (chain ID 42161) for cheaper transactions. Adjust the slippage tolerance to 0.5% when interacting with decentralized exchanges; values above 2% expose you to sandwich attacks. Transaction signing uses deterministic ECDSA (secp256k1) curved signatures. Each outgoing transfer requires explicit approval through the pop-up interface–no batch signing is supported by default. The "Activity" log records every signed message hash with the corresponding block timestamp from Etherscan. To revoke a contract approval, input the spender address into the custom transaction field with a 0-token value and a high gas price (50 Gwei for mainnet congestion). Portal Wallet Extension Setup and Usage Guide Immediately install the application from the official Chrome Web Store listing, verifying the developer identity as “Portals HQ” and checking the total number of user reviews before clicking “Add to Chrome.” After the icon appears in your toolbar, click it once to generate a twelve-word recovery phrase; do not photograph, scan, or store this phrase digitally. Write it down on a physical medium using a pen, keep it in a fireproof safe, and do not share any portion of it with third-party websites or support agents. To deposit funds, press the “Receive” button and copy the alphanumeric address or scan the QR code from a reliable source such as Coinbase or Binance. Confirm the displayed network matches the token’s native chain; for example, use Base for USDC and Ethereum mainnet for the native currency. Initiate a test transaction of 0.001 ETH first, waiting for two network confirmations on a block explorer like Etherscan, before processing larger amounts. For interacting with decentralized applications, navigate to the dApp’s interface, click “Connect,” select this browser module from the pop-up, and approve the signature request without revealing your private key. When authorizing token swaps, adjust slippage to 0.5% for highly liquid pairs, or 2% for low-liquidity tokens, to avoid failed transactions. Monitor gas fees on sites like Etherscan Gas Tracker and set a maximum priority fee of 1.2 gwei during off-peak hours to minimize transaction costs. Downloading and Installing the Portal Wallet Extension from the Official Source Only use the Chrome Web Store for this specific plugin. Search for “Portal” by its developer name “Portal” listed under “Blockchain to Bitcoin Bridge.” Confirm the publisher is verified and the total user count exceeds 100,000. Click “Add to Chrome” and select “Add extension” in the pop-up dialog. The icon will appear in your toolbar immediately after installation. For Firefox users, navigate to the Firefox Browser Add-ons store. Type “Portal” into the search bar. Flag any clones or misspellings by checking the developer’s URL–the legitimate version is published by “portalhq.io.” Hit “Add to Firefox” and approve the requested permissions. A notification will confirm the component has been pinned to your extensions bar. No restart is required. Brave and Edge browsers also support this tool via their respective Chromium-based stores. Open the Edge Add-ons site or Brave’s extensions panel. Look for a combined rating above 4.5 stars and at least ten thousand installs. Click “Get” or “Install.” Grant permissions to access page data only. This action enables the local vault to generate seed phrases and private keys directly on your machine. Reject all third-party download sites distributing .crx or .zip files. Only the official storefront guarantees an unaltered binary signed by the developer. After installation, right-click the toolbar badge and select “Manage extension.” Enable “Site access” set to “On click.” This restricts the component from reading browser tabs without your explicit authorization. Pin the icon for immediate access. Creating a New Wallet: Setting Up Your Seed Phrase and Master Password Disconnect your device from any network before generating a new seed phrase. A hardware-generated mnemonic, following the BIP-39 standard, produces 12 or 24 words from a 2048-word list. Select 24 words for the highest entropy (256 bits), as 12-word phrases (128 bits) are theoretically more vulnerable to brute-force attacks over decades. Write the words on a fireproof, waterproof steel plate–not paper, which degrades or burns. Never type them into any connected device, screenshot them, or store them in cloud services. Verify each word immediately: after writing, confirm the spelling, capitalization (lowercase only), and sequence number against the displayed list. A single miswritten word renders the recovery useless. Test the recovery process: before funding the address, wipe the software instance, reinstall it, and attempt to restore using your mnemonic. This proves your backup works under stress. Master password creation rules: use a minimum of 16 characters, mixing uppercase, lowercase, digits, and symbols. Avoid dictionary words, personal dates, or keyboard patterns (e.g., "qwerty123!"). A password manager generating a random 24-character string is optimal. The master password encrypts the local data file containing your keypairs. If this password is weak (under 12 characters or common phrases), an attacker with file access can brute-force it using tools like Hashcat at billions of attempts per second. Do not reuse this password across any other service. Write the password down on a separate metal plate from the seed phrase, stored in a different physical location (e.g., one in a bank safe deposit box, the other at home). Critical operational sequence: generate the mnemonic offline, store the steel plates, then set the master password. Only after these steps, reconnect to the internet and fund the public address derived from the seed. Use a passphrase (BIP-39 optional 25th word) added to your mnemonic for a hidden wallet layer–this prevents physical theft of your plates from compromising funds. The passphrase should be memorized, never stored. Without it, the seed phrase alone generates a completely different set of keys. Test this layered recovery twice with small test amounts before depositing real assets. Importing an Existing Wallet Using a Private Key or Seed Phrase Open your vault interface and select the option to import an existing account. For a private key, locate the 64-character hexadecimal string (0x prefix optional) or the Base58 encoded format (typically 51-52 characters for Bitcoin-based chains). Paste it directly into the designated field. If using a seed phrase, ensure you have the complete BIP-39 mnemonic list of 12, 18, or 24 words in the correct order. Verify each word against the BIP-39 English wordlist (2048 words) to avoid typos from similar-sounding terms like “steak” versus “stake” – a single error invalidates the entire derivation path. Select the correct derivation path for your specific blockchain: m/44'/60'/0'/0/0 for Ethereum mainnet, m/44'/0'/0'/0/0 for Bitcoin, or m/44'/118'/0'/0/0 for Cosmos-based chains. Do not use an internet-connected device to store clipboard content after pasting keys; manually re-type sensitive data when possible. Choose the target network before pasting your key or seed to trigger correct address derivation. For HD wallets, specify the account index (starting at 0) to access funds stored on alternate paths like m/44'/60'/1'/0/0. Validate the generated address against your known public address using a separate trusted block explorer before executing any transactions. If importing a legacy wallet (pre-BIP39), convert your seed to the BIP39 format using a tool like bx mnemonic new from the Bitcoin Core suite, offline. Always clear the input field and restart the software after a single import to prevent residual seed data in RAM snapshots. Connecting the Portal Wallet Extension to a Specific Blockchain Network Open the extension’s main menu and click the network selector icon, typically located at the top of the interface. From the dropdown, choose "Custom Network" or "Add Network" depending on your client version. You will need to input the exact RPC URL, Chain ID, Symbol, and Block Explorer URL for your target chain. For example, to [https://extension-web3.com/portal-dex-extension-guide.php Connect Portal Wallet to dApp] to Base Sepolia, enter: RPC URL: https://sepolia.base.org, Chain ID: 84532, Symbol: ETH, Explorer: https://sepolia.basescan.org. Double-check each parameter against the network’s official documentation–incorrect Chain IDs will result in transaction rejection or data display errors. ParameterExample Value (Polygon zkEVM Cardona)Source for Verification RPC URLhttps://rpc.cardona.zkevm-rpc.comPolygon zkEVM docs Chain ID2442Chainlist.org SymbolETHNative token of the L2 Block Explorer URLhttps://cardona.zkevm.etherscan.ioOfficial block explorer After saving the custom network, the interface will automatically switch to it. Verify the connection by checking the displayed chain name and ID in the top bar. For testnets, ensure you have adequate test tokens–on Ethereum Sepolia, you can obtain free ETH via the Alchemy faucet (0.05 ETH per request) or Infura faucet (0.1 ETH daily). For Optimism Sepolia, use the Optimism faucet which requires a GitHub account and limits to 0.5 ETH every 24 hours. If the network does not appear in the dropdown, restart the extension from your browser’s extensions settings and re-add it. For chains requiring EIP-1559 compliance (most Ethereum L2s post-2022), the extension will automatically use fee estimation based on base fee and priority fee parameters. On Arbitrum One, for instance, the extension calculates gas using the Sequencer’s L1 data fee–on the network addition screen, leave "Max Priority Fee" empty unless you are debugging high-congestion scenarios. Ignore any pre-filled fields from previous manual entries; always clear form cache by clicking "Reset" or closing the modal before inputting fresh data. A common error: using the wrong Chain ID for BNB Smart Chain (56 for Mainnet, 97 for Testnet) will cause all transactions to fail immediately. To switch between networks already configured, click the network icon, select from the list, and wait 2–3 seconds for the provider to update. For production mainnets (Ethereum, Avalanche C-Chain, Polygon PoS), verify the RPC URL uses HTTPS and comes from a trusted provider (Infura, Alchemy, QuickNode). Avoid free public RPCs like those from Ankr or Pokt for high-value transactions–they have rate limits of 100 requests per second and may throttle during peak gas times. For local development nodes like Ganache or Hardhat Network, set Chain ID to 1337, RPC URL to http://127.0.0.1:8545, and disable SSL verification if prompted. Q&A: I just installed the Portal wallet extension on Chrome, but when I click the icon, it only shows a blank white screen. I’ve tried refreshing the page and restarting the browser twice. Any idea what’s going wrong? This is a known issue with some Chromium-based browsers if the extension doesn’t have the correct permissions or if there’s a corrupted cache for the extension itself. First, go to `chrome://extensions` in your address bar (or `brave://extensions` if you use Brave), find the Portal wallet, and click the "Details" button. Scroll down and ensure the "Allow access to file URLs" toggle is off, and that "Site access" is set to "On all sites" (temporarily for testing). If that doesn’t work, remove the extension completely, clear your browser’s cache (not just cookies), and reinstall the latest version from the official Chrome Web Store. For a small percentage of users, the issue is caused by a hardware acceleration conflict. Try disabling hardware acceleration in Chrome’s settings (`chrome://settings/system`) after reinstallation. If the screen is still white after these steps, check if a VPN or ad-blocker is interfering—disable them one by one. One user fixed this by uninstalling a "noads" extension. I just installed the Portal Wallet extension. After creating a new wallet, it showed me a 12-word recovery phrase. I didn't write it down because I thought it was stored in the browser. Can I just log in again later using my email or password? No, you cannot log in again using an email or password. The 12-word recovery phrase (also called a seed phrase) is the only way to restore access to your wallet if you clear your browser data, switch computers, or reinstall the extension. The Portal Wallet extension does not store your private keys on a central server, and there is no "forgot password" option. Without that phrase, your funds are permanently inaccessible. Write it down on paper and store it in a safe place immediately. Do not save it in a text file, take a screenshot, or type it into any website. I have two browser profiles on the same computer. If I install Portal Wallet on both profiles, will they share the same wallet, or will each profile have its own separate wallet? Each browser profile will have its own independent instance of Portal Wallet with its own local storage. Installing the extension on a second profile does not automatically duplicate your wallet. You will have to either create a new wallet or import your existing wallet using the 12-word recovery phrase on the second profile. If you import the same phrase, both profiles will control the same blockchain address. However, keep in mind that transaction history and settings are not synced between profiles. This setup is useful for testing, but be aware that if your recovery phrase is compromised, both instances are at risk.
