Fast wallet extension setup and usage guide

Open the Chrome Web Store and search for the official repository by the development team. Verify the publisher’s name matches the project’s GitHub organization–fraudulent clones often add a single altered letter. Click “Add to Chrome,” then immediately navigate to chrome://extensions. Toggle “Developer mode” (top right) to inspect the loaded module’s ID. This ID must match the one listed on the project’s documentation page, typically a 32-character hex string. If it mismatches, remove the add-on and report the listing.

After confirmation, click the puzzle-piece icon in the toolbar and pin the new icon. Right-click the icon and select “Options.” Here, set a master password of at least 16 characters, mixing uppercase, digits, and special symbols. Do not reuse a password from any other service. Generate a recovery seed phrase and write it on paper–store that paper in a fireproof safe, not on any device. Take a second seed copy and seal it in a safety deposit box. Test the recovery process immediately: log out, reinstall the module, and restore using only the paper phrase. If recovery fails, delete the account and start over with a different seed.

For daily transactions, enable automatic session locking after 60 seconds of inactivity–this prevents exposure if you step away. Disable “auto-connect to dApps” in the preferences; manually approve each connection request. Use a dedicated browser profile solely for this plugin, with no social media or email tabs open. Install a DNS-over-HTTPS extension and set your provider to Cloudflare (1.1.1.1) to block interception of your network calls. Never click “approve” on a pop-up unless you have visually matched the contract address on an independent block explorer like Etherscan, not on the app’s own site.

Fast Wallet Extension Setup and Usage Guide

Begin by downloading the browser module exclusively from the official Chrome Web Store or the developer’s verified GitHub repository. Check the cryptographic hash of the installation file against the published checksum–skip this step only if you want to risk a trojan. After the module installs, right-click the icon and select “Manage extensions” to confirm the permission set is limited to “storage” and “script injection.” Refuse any pop-up requesting access to your clipboard or browsing history.


Open the module’s main panel via the toolbar icon.
Click “Create New Identity” and store the 24-word recovery phrase offline–paper in a fireproof safe, not a screenshot.
Set a local PIN between 6 and 12 digits; this PIN is never sent to any server and unlocks only the local session.


For transaction confirmations, require at least two manual approvals per operation in the settings tab. Navigate to “Security” and enable “Transaction limits per hour” with a default cap of 0.5 ETH or equivalent. If you receive a signed message request that does not display a clear, human-readable amount in the preview pane, reject it instantly–malicious contracts often hide data in raw hex fields.


To load assets, transfer ERC-20 tokens from a cold address to the module’s receiving address found in the “Deposit” section. Do not use the built-in “Buy” feature tied to a third-party fiat on-ramp unless you have verified the partner’s regulatory status in your jurisdiction. Instead, fund the address from an exchange with a separate withdrawal address each time to reduce address clustering risks.


Batch signing: Use this only for airdrop claims or staking rewards where each transaction is identical.
Hardware signing: Pair a Ledger or Trezor via USB to authorize high-value transfers above $1,000.00.
Session lock: Set automatic lock after 5 minutes of inactivity under “Advanced security options.”


When interacting with decentralized applications, always inspect the “permissions” pop-up before clicking “Connect.” A legitimate DeFi interface will request only your public address and the right to suggest transactions. If a site demands access to your address book or the ability to move tokens without confirmation, revoke permissions immediately via the “Connected Sites” panel. Maintain a secondary profile in the module dedicated solely to testing unknown dApps with a minimal balance below $50.


Recovery from a lost device requires the 24-word phrase and the specific derivation path (usually m/44´/60´/0´/0). Enter the phrase directly into a fresh module installation on a clean machine. After restoration, generate a new set of keys and transfer remaining assets to it–assume the old phrase was compromised during the recovery process. Repeat this step every six months or after any device repair.


Monitor network fees manually before each transaction; the module’s “gas estimation” tool tends to underprice during congestion by 10–15%. Set a custom gas multiplier of 1.2x for standard speed or 1.5x for time-sensitive swaps. For batch withdrawals from exchanges, use the module’s “Send to multiple addresses” function with a single transaction, paying only one base fee rather than separate costs for each recipient.

Q&A:
I installed the Fast Wallet extension, but it keeps asking me to create a new wallet instead of letting me import my old one. Where is the "import" option hidden?

You need to look for a small text link, usually gray and located below the big "Create Wallet" button on the startup screen. It often says "Import existing wallet" or "Recover wallet using seed phrase." Click that, and you will be asked for your 12 or 24-word recovery phrase. Note that the extension will clear its local storage and reset if you try to switch modes after setting up, so only use this during the initial setup screen.

Does the Fast Wallet extension work with hardware wallets like Ledger or Trezor, or is it strictly a hot wallet?

Fast Wallet is designed as a pure hot wallet extension. It does not support direct hardware wallet integration through USB or Bluetooth. If you try to use the "Connect Hardware Wallet" menu option, you will get an error saying "Device not recognized." You must keep your private keys inside the browser extension storage. For security against malware, use a dedicated browser profile or an incognito window with the extension enabled. Do not use this wallet if you plan to store large amounts of cryptocurrency.

I accidentally sent ETH to my Fast Wallet address on the Polygon network instead of Ethereum Mainnet. Can I recover those funds?

Yes, you can recover them, but it requires manual steps. First, open the Fast Wallet extension and go to the network dropdown menu at the top. Scroll down and select "Polygon Mainnet." Your same public address will show a balance of zero at first. You need to add the Polygon network manually if it is not listed. Go to Settings > Networks > Add Custom. Enter the Polygon RPC URL (usually https://polygon-rpc.com), the chain ID 137, and the symbol MATIC. Once the network is active, your ETH will appear as wrapped ETH or native ETH depending on the token standard. You can then bridge it back to Ethereum Mainnet using a third-party bridge like the official Polygon Bridge. Make sure you have a small amount of MATIC in that wallet to pay the gas fees for the bridge transaction.

How do I change the default gas fee from "Slow" to "Fast" for a time-sensitive transaction? I missed a price window because my transaction was pending for 20 minutes.

Before you confirm any transaction, look for a small gear icon or a "Gas Settings" button next to the estimated fee. Clicking it opens a slider or three preset options: "Slow," "Average," and "Fast." Select "Fast" to pay a higher gas price (like 50-100 gwei on Ethereum) for priority inclusion in the next block. If the confirmation window is already closed, you cannot retroactively change the gas on the pending transaction within Fast Wallet. You would need to open your wallet list in the extension, find the pending transaction, cancel it (which also costs a small fee), and resubmit with the correct gas settings.

My Fast Wallet extension shows "0 balance" for my tokens, but I can see the transactions on Etherscan and they are confirmed. What did I do wrong?

This is usually a token list mismatch or a corrupted cache. First, click the three dots menu in the Fast Wallet popup and select "Refresh Tokens" or "Reload Balances." If that does not work, go to Etherscan, paste your wallet address, copy the exact token contract address for the missing token (e.g., the USDC contract address). Return to Fast Wallet and use the "Import Token" feature (usually found at the bottom of your token list). Paste the contract address. If the token still does not appear, the extension might have a block height sync error. Go to Settings > Advanced > "Reset Extension State." This will force a full resync without deleting your private keys. After the reset, close and reopen the browser, then log back into the extension. Your balance should update within 30 seconds.

I just installed the Fast Wallet browser extension, but I don't see the icon next to my address bar. Where is it, and how do I actually open the wallet to start using it?

The Fast Wallet extension icon should appear automatically after installation, but sometimes browser settings can hide it. On Chrome, look to the right side of your address bar for a small puzzle piece icon. Click it, and you'll see a list of your extensions. Find "Fast Wallet" and click the pin icon next to it so that it stays visible. On Firefox, you might need to click the menu button (three horizontal lines) and choose "Customize Toolbar..." to drag the extension icon to your toolbar. If the icon still doesn't show, try restarting your browser completely. Once the icon is visible, click it to open the wallet panel. The first time you do this, you'll be prompted to either create a new wallet (which generates a seed phrase) or import an existing one using a recovery phrase or private key. Make sure you are on a secure network and not being observed when writing down your seed phrase—it is the single most important piece of information for accessing your funds.
