Verify the developer name matches the verified publisher exactly and check that the file size in bytes matches the checksum hash listed on the project’s GitHub releases page. Do not use any third-party sites or promotional links from forums.&lt;br&gt;&lt;br&gt;&lt;br&gt;After installation, pin the icon to your toolbar. Click it and select “Create a new vault.” Write down the 12- or 24-word recovery phrase on paper only–do not store it digitally, screenshot it, or type it into any cloud document. Confirm the phrase by selecting the words in the exact order. Set a strong passphrase (at least 12 characters with lowercase, uppercase, a digit, and a special symbol) that is different from any password you use elsewhere. This passphrase encrypts the vault locally; the vault never sends raw keys over the network.&lt;br&gt;&lt;br&gt;&lt;br&gt;Configure the network endpoints manually. Use a dedicated RPC provider (e.g., Infura, Alchemy) with your own API key instead of the default public nodes. Disable the “automatic block scanning” feature to reduce memory usage; trigger scans only when you initiate a transaction. Assign separate sub-accounts by numbering them, not by labels, to prevent accidental disclosure of balances.&lt;br&gt;&lt;br&gt;&lt;br&gt;Test the recovery process immediately. Before moving any actual assets, delete the vault from the browser, rebuild it from the paper phrase, and verify that all sub-accounts and custom RPC settings are restored. If they are not, contact support with the exact browser version and a debug log from the extension’s settings page–do not share the log publicly because it may contain hashed device identifiers.&lt;br&gt;&lt;br&gt;&lt;br&gt;For every transaction, always enable “simulate before send” in the transaction confirmation window. This runs a dry run on the target chain to detect token approval traps or unexpected gas spikes. Manually set a gas price cap; do not rely on “fast” presets during high network congestion periods. After the transaction broadcasts, monitor the status from a block explorer using the transaction ID provided in the vault’s history tab–do not refresh the vault view repeatedly as this drains the local cache.&lt;br&gt;&lt;br&gt;&lt;br&gt;Store the paper recovery phrase in a fireproof safe with a backup location in a sealed envelope at a separate residence. Rotate the vault passphrase every six months by exporting and re-importing the encrypted keyfile. Never attach the vault to a browser that has auto-fill or form-saving scripts active; use a dedicated browser profile with all extensions disabled except for this one.&lt;br&gt;&lt;br&gt;Portal Wallet Extension Setup and Usage Guide&lt;br&gt;&lt;br&gt;Download the signed binary only from the official GitHub releases page, verifying the SHA-256 checksum against the published hash to confirm file integrity. For Chromium-based browsers, load the unpacked folder via `chrome://extensions` after enabling Developer mode, ensuring the manifest version 3 file is present. Firefox users must sign the add-on through the AMO portal or load a temporary add-on in `about:debugging` for testing. Reject any prompts from unofficial sources or pop-ups asking for seed phrase entry during installation.&lt;br&gt;&lt;br&gt;&lt;br&gt;After installation, click the icon in the toolbar and select &quot;Create new vault&quot;. Write down the provided 24-word recovery phrase on paper using a Stamp (or similar) – never store it digitally, take a screenshot, or transmit it over any network. Confirm the phrase by selecting the words in the correct order from scrambled options. Set a strong password of at least 12 characters, mixing uppercase, lowercase, digits, and symbols; this password unlocks the local vault each session and is not recoverable. Avoid using biometric unlock on shared devices.&lt;br&gt;&lt;br&gt;&lt;br&gt;To send assets, first acquire the recipient’s public key (0x-prefixed hex string for EVM chains, or bech32 for Cosmos/Polkadot). Click &quot;Send&quot;, paste the key, input the amount, and verify the exact token contract address if using a non-native asset. Estimate gas fees manually by checking current network congestion on a block explorer like Etherscan or Polygonscan; the tool’s auto-suggestion often overestimates by 30-50%. For multi-chain transactions, ensure the selected network in the dropdown matches the target chain – sending BSC tokens to an Ethereum address results in permanent loss.&lt;br&gt;&lt;br&gt;&lt;br&gt;For security, periodically export and backup the private key for each account by navigating to Account Details &gt; Export Private Key, storing this in an encrypted, offline container (e.g., a VeraCrypt volume). Revoke token approvals monthly via the integrated approval manager interface; focus on unlimited approvals (uint256 max) to DeFi contracts you no longer use. Disconnect from all dApps after each session using the &quot;Connected Sites&quot; menu, as persistent connections allow dApps to read your address and propose unsigned transactions even when idle. Enable the auto-lock timer to trigger after 5 minutes of inactivity for mobile hardware security.&lt;br&gt;&lt;br&gt;Installing the Portal Wallet Extension from the Chrome Web Store&lt;br&gt;&lt;br&gt;Initiate the process by opening Google Chrome and navigating directly to the Chrome Web Store’s search bar. Enter the exact name of the tool you intend to install, ensuring you select the official listing published by the developer team. Verify the publisher name, total user count, and recent update date before proceeding; a counterfeit copy often lacks detailed permissions descriptions or uses an inconsistent color scheme in its icon.&lt;br&gt;&lt;br&gt;&lt;br&gt;Click the “Add to Chrome” button located in the upper-right corner of the listing page. A pop-up window will appear, detailing the specific permissions this tool requests, such as reading and altering data on visited websites. Review these permissions critically–any request for access to “all data on your computer” or unrelated social media domains is a clear red flag. Confirm only if the permissions align strictly with blockchain interaction functionality.&lt;br&gt;&lt;br&gt;&lt;br&gt;After approval, Chrome initiates a silent download and automatic installation of the browser module. A confirmation dialog will notify you that the new component has been added, and a puzzle-piece icon in the top-right toolbar will display your freshly loaded software. No page refresh is required, though closing and reopening your browser can resolve rare icon visibility glitches.&lt;br&gt;&lt;br&gt;&lt;br&gt;Pin the newly installed module to your toolbar by clicking the puzzle-piece icon (Extensions menu) and selecting the pin icon next to its name. This ensures persistent visibility and one-click access for future transactions. Without pinning, the item remains hidden behind a drop-down menu, adding unnecessary friction to every interaction.&lt;br&gt;&lt;br&gt;&lt;br&gt;Immediately after pinning, click the icon to initialize the software for the first time. You will be prompted to either create a new identifier or recover an existing one using a mnemonic phrase. Choose “Create a new identity” if you have no prior backup; the software will then generate a 12- or 24-word recovery sequence. Write these words on paper using a pen–avoid digital screenshots, cloud storage, or copy-paste operations entirely.&lt;br&gt;&lt;br&gt;&lt;br&gt;Once the identity is created, the system will automatically request a network connection. Confirm the default network selection (typically Ethereum Mainnet) unless you specifically require a test environment. The interface will display your public address and zero balance. Navigate to the software’s settings panel to adjust currency display preferences, gas fee thresholds, and default block explorer URLs before executing any first transaction.&lt;br&gt;&lt;br&gt;&lt;br&gt;Test the installation by sending a micro-transaction (e.g., 0.0001 ETH) to a secondary address you control. Monitor the transaction hash via the built-in history tab; a pending status lasting longer than five minutes indicates either an incorrect network configuration or insufficient gas settings. If the transaction clears, the installation is functionally complete and ready for production use.&lt;br&gt;&lt;br&gt;Creating a New Wallet and Writing Down Your Seed Phrase&lt;br&gt;&lt;br&gt;Click the &quot;Create New&quot; button and immediately prepare a physical medium like a steel plate or fireproof paper–do not rely on screenshots, cloud drives, or digital notes. The seed phrase is a sequence of 12, 18, or 24 words your local device generates using cryptographic entropy; your browser caches this data temporarily but never transmits it over the network. Once the interface displays the list of words, read each one aloud while writing them down sequentially, verifying every third word against the on-screen copy to catch misspellings or transpositions.&lt;br&gt;&lt;br&gt;&lt;br&gt;Use a ballpoint pen on acid-free paper stored in a zip-lock bag with silica gel packets to prevent humidity damage.&lt;br&gt;Number each word (1-12, 1-18, or 1-24) in the same order as presented–reordering them makes recovery impossible even if you remember the correct words.&lt;br&gt;Store the physical copy in a fireproof safe at a second location (not in the same building as your computer) to mitigate burglary and fire risk.&lt;br&gt;&lt;br&gt;&lt;br&gt;After completing the manual backup, the application will prompt you to confirm 2-4 randomly selected words from your phrase. This test detects common errors like swapping &quot;giraffe&quot; with &quot;girafe&quot; or misplacing a word from position 7 into position 8. If you fail this verification, you must restart the process from scratch–do not attempt to guess or correct the sequence manually, as even a single wrong character invalidates the entire derivation path for your future signatures.&lt;br&gt;&lt;br&gt;&lt;br&gt;For long-term custody, consider splitting the seed phrase into three shards using a simple XOR split or a hardware backup device that stores the recovery data offline. Never expose all words to a single camera lens, phone keyboard, or voice-activated assistant–your microphone and webcam are attack surfaces that can be compromised by remote access trojans. A single breach of the full phrase gives an attacker permanent control over every cryptographic identity derived from it.&lt;br&gt;&lt;br&gt;&lt;br&gt;Test your backup immediately after creation by closing the application, reopening it, and selecting &quot;Import Existing&quot; instead of &quot;Create New.&quot; Enter your written words exactly as recorded (lowercase, single spaces between words) and confirm the derived public address matches the one shown during the creation process. If the addresses mismatch, shred the current paper copy and generate a fresh account with a new seed phrase–this verification step takes four minutes but prevents catastrophic loss of assets years later when your memory of the phrase has faded.&lt;br&gt;&lt;br&gt;Q&amp;A: &lt;br&gt;I just installed the Portal Wallet extension. When I try to create a new wallet, it’s asking me to save a 12-word phrase. Can I just take a screenshot of it instead of writing it down on paper?&lt;br&gt;&lt;br&gt;No, you should absolutely avoid taking a screenshot or storing that phrase in any cloud service (like Google Drive or iCloud). A screenshot can be accessed by malware on your device or through a hacked account. That 12-word seed phrase is the only key to your wallet. If you lose it or get it compromised, neither [https://extension-start.io/portal-dex-wallet-extension-guide.php Portal Wallet setup] Wallet nor any support team can help you recover your funds. Write it down on paper with a pen, store it in a safe place (like a fireproof safe), and never type it anywhere except when you are asked by the wallet itself during recovery.&lt;br&gt;&lt;br&gt;I’ve connected Portal Wallet to a dApp on Solana, but when I try to approve a transaction, the pop-up window shows a &quot;Simulation Failed&quot; error. What does that mean and what should I do?&lt;br&gt;&lt;br&gt;This error means the Portal Wallet tried to simulate the transaction (test it without executing it) to see what would happen, and the simulation returned an error. This could happen for a few reasons: the dApp is interacting with a contract that is currently paused or broken, the transaction parameters are invalid (like a very low slippage setting for a swap), or the dApp might be attempting to drain your wallet (a malicious contract). You should never click &quot;Confirm&quot; or bypass this warning. Instead, click &quot;Reject.&quot; Then, double-check the dApp URL (scammers use fake sites). If you are confident the site is real, try adjusting your slippage or transaction speed in the dApp’s settings. If the error persists, contact the dApp’s support team, not Portal Wallet’s support.&lt;br&gt;&lt;br&gt;I want to use Portal Wallet across multiple browsers. I set it up on Chrome, but can I just export my private key from Chrome and import it into Firefox?&lt;br&gt;&lt;br&gt;You can, but the safer method is to use the wallet’s &quot;export seed phrase&quot; option and import that phrase into Firefox. However, importing the seed phrase into a second browser means you will have two separate installations that control the same wallet. If you lose your Firefox installation or it gets compromised, the attacker gains access to the same wallet. A better practice is to use a hardware wallet (like Ledger) connected to Portal Wallet. Then you can use the same Ledger in any browser without ever exposing your seed phrase to the computer. If you must use the software wallet across browsers, store the seed phrase securely offline and only type it to recover the wallet on a clean machine.&lt;br&gt;&lt;br&gt;From the &quot;Usage Guide&quot; part of the article, it says I can stake SOL directly from the Portal Wallet. How does the unstaking process work? Do I need to wait, or is it instant?&lt;br&gt;&lt;br&gt;Staking SOL through Portal Wallet means you are delegating your tokens to a validator on the Solana network. The protocol defines a specific unbonding period (usually a few days to a week, depending on the network). When you click &quot;Unstake&quot; in Portal Wallet, the extension creates a transaction to start that unbonding process. Your tokens do not appear in your wallet immediately. You will see them as &quot;unstaking&quot; in the wallet interface. After the unbonding period ends (Portal Wallet will usually show a countdown), you need to submit another transaction to fully withdraw the SOL back to your spendable balance. The guide should clarify that you cannot cancel the unstaking once it starts, so plan ahead if you need fast liquidity.&lt;br&gt;</div>
