Pontem wallet setup guide for beginners step by step
Pontem wallet setup guide for beginners step by step
Beginners must first acquire a physical device that stores private keys offline (cold storage). This completely isolates critical data from internet-connected computers. After unboxing your hardware device, install its official companion application (Ledger Live or Trezor Suite) on your desktop. Initialize the device and write down the 12 or 24-word seed phrase on paper only–never photograph it, store it in a cloud file, or type it into any app. This restoration phrase is the absolute backup; without it, all assets are permanently irrecoverable.
With the hardware device initialized, open the companion app and navigate to the “Manager” section. Search for the “Aptos” application and install it directly onto the hardware device. The installer will push the blockchain-specific code into the firmware, consuming about 10–15 KB of memory. Once installed, open the Aptos application on the device. You will see an on-screen prompt: “Aptos Ready.” Simultaneously, ensure your web browser (Chrome or Firefox) has the “Martian” or “Fewcha” browser add-on installed. These are custodial interfaces that Connect Pontem Wallet to dApp to your hardware key via USB or Bluetooth–none of them store your seed phrase.
In the browser add-on, select “Connect Hardware Wallet” from the login dropdown. Choose your device brand (Ledger or Trezor). The add-on will communicate with the hardware device using WebHID or WebUSB protocols. A permissions pop-up appears; allow it. The hardware device screen will flash “Export Public Key.” Press the right button to approve. The add-on then reads only the public address (no private data is exposed). This address is a string of 66 alphanumeric characters starting with “0x.” Copy this address and save it in a password manager–not in a text file on your desktop.
Before transferring any tokens, test the connection. On the browser add-on interface, use the “Receive” function. The add-on displays a QR code and the same 66-character address. Send a minimal amount (e.g., 0.1 APT) from an exchange or another wallet to this address. Wait for two block confirmations (approximately 10–15 seconds on Aptos). Then, execute a small send back to the source. The hardware device will show “Approve Transaction” and the amount in APT. Confirm on the device. This verifies the entire transmission loop–private key signing on the cold device, broadcast through the browser add-on, and balance updates on-chain.
For daily use, keep the hardware device unplugged except when authorizing transactions. Never enter your seed phrase into any mobile app, browser pop-up, or recovery tool. If you lose the physical hardware, use the paper seed phrase to restore onto a new hardware device–never into a software-only environment. This single precaution eliminates the vast majority of theft vectors targeting newcomers.
Pontem Wallet Setup Guide for Beginners Step by Step
Download the official browser extension solely from the Chrome Web Store or the Mozilla Add-ons site, verifying the publisher is "Pontem" and that the extension has at least 10,000 users. Click "Add to Chrome" or "Add to Firefox," then pin the app icon to your toolbar. Open the extension and select "Create a new vault." Write down the 12-word mnemonic seed exclusively on paper using a metal stamping kit (e.g., Billfodl or Cryptosteel), never store this phrase digitally, nor in a screenshot, nor in a cloud service. Confirm the seed phrase order by clicking the words in the correct sequence, then set your strong passcode (minimum 15 characters, mixing upper, lower, digits, and symbols) and lock time to 1 minute.
After creating the vault, immediately activate the "Auto-Lock" toggle and set timeout to 60 seconds. Navigate to "Security & Privacy" and enable "Anti-Phishing Distinguisher" to inject a custom code word on every transaction prompt. Connect to a remote procedure call (RPC) endpoint manually–navigate to "Settings" > "Networks" > "Add Network", input the official Sui Testnet details (RPC URL: https://fullnode.testnet.sui.io:443, Chain ID: 7af94d4e87a2), or use a dedicated public RPC like BlastAPI with API key for production. For token recovery, use the "Import Tokens" function by pasting the contract address (e.g., SUIB: 0x338...f1) and decimal of 9; never accept airdropped tokens without verifying their origin on SuiScan.
For hardware device pairing, use Chrome-based browsers only via a USB cable and install the Sui-specific app on Ledger Live (version 1.2.0 or newer). On the "Connect Hardware Wallet" screen, click "Ledger", wait for the "Ethereum" and "Sui" app icons to appear, and approve the BIP32 path m/44'/784'/0'/0/0 on the Ledger. Test the connection by sending 0.01 SUI to a second address you control; verify the transaction appears on SuiScan within 5 seconds. A below lists the typical durations for each phase:

Downloading the Pontem Wallet Extension from the Chrome Web Store
Open the Chrome browser and navigate directly to the Chrome Web Store. Type "Pontem Wallet" into the search bar located at the top-left corner of the store. Press Enter. The first result should be the official extension published by "Pontem Network". Verify the publisher name before proceeding. Click on the result to open the extension's detail page.
Inspect the extension's rating and number of users. Look for a high rating, ideally 4.5 stars or above, with thousands of downloads. Read through recent user reviews to check for any recurring complaints about functionality or security. A low rating or suspicious reviews are red flags. The extension icon should feature a recognizable blue and white emblem.
Locate the blue "Add to Chrome" button on the right side of the detail page. Click it. A pop-up window will appear listing the permissions the extension requires. Review these permissions carefully. Typical permissions include "Read and change all your data on the websites you visit" and "Manage your downloads". If the permissions seem excessive or unrelated to a crypto tool, do not proceed.
Click "Add Extension" in the pop-up window to confirm the installation.
After a few seconds, the extension icon will appear in the top-right toolbar of your browser.
Pin the extension by clicking the puzzle piece icon in the toolbar and selecting the pin icon next to the new entry.
Check that the extension menu opens correctly. Click the new icon; it should display a clean interface with options to create a new vault or import an existing one. If the menu shows an error message or fails to load, remove the extension and re-download it from the original source. Corrupted downloads are rare but possible.
For maximum security, avoid downloading any "cracked" or modified versions of this tool from third-party websites. Only use the official Chrome Web Store listing. The store's vetting process, while not infallible, reduces the risk of malicious code. After confirmation, the extension is ready for initial configuration.
Close and reopen the Chrome browser after installation to ensure the extension registers correctly. A fresh browser session prevents conflicts with cached data from the store. The icon should remain visible after restarting. If it disappears, repeat the pinning process from the toolbar menu. You are now prepared to proceed with the next phase of the operational initialization.
Creating a New Wallet and Securing Your Seed Phrase
Open the application and select the option to generate a fresh cryptographic vault. The interface will immediately prompt you to create a strong, unique passcode (minimum 8 characters, mixing uppercase, lowercase, numbers, and symbols) that encrypts the local data on your device. Never reuse a password from another service for this device-level lock.
Upon confirming your passcode, the software will display a sequence of 24 distinct words. Write these words exclusively on paper using a permanent ink pen, never a digital medium. Print two physical copies and store them in separate, fireproof safes located in different geographic locations. Avoid storing the phrase in cloud services, screenshots, email drafts, or password managers, as these introduce remote attack vectors.
Verify the sequence by entering the requested words in the correct order on the next screen. If you transpose a word or misplace an index, the generated keys will be invalid, and you must discard the entire session immediately to start from scratch. Do not correct typos; abort and regenerate.
Attach a metal stamping kit to your backup process. Engrave the 24-word sequence onto a set of stainless steel plates using a numeric punch set. This method resists fire damage, water submersion, and physical decay that degrades paper over decades. Purchase plates specifically designed for cryptographic seed storage, not generic metal tags, to ensure durable embossing.
Label each physical backup clearly with the date of creation and a unique identifier that only you recognize (e.g., a personal code unrelated to crypto). Do not write the words "seed phrase," "recovery phrase," or any obvious crypto terminology on the storage container. A casual observer should see only a nondescript metal slab or paper in a box.
Test the recovery process immediately after creating the backup. Close the application completely and reinstall it on a different device. Input the 24-word sequence exactly as written, ensuring capitalization and spacing match the original display. If the restored vault does not show zero balance and zero transaction history, your backup is corrupted–destroy all copies and regenerate.
Store one set of engraved plates in a bank safety deposit box under your individual name. Place the second set in a trusted family member’s home safe, not in your own residence. This split decreases the probability of total loss from a single disaster (burglary, flood, fire) to near zero.
Set a calendar reminder for every six months to verify the physical condition of your backups. Check for rust, ink fading, or plate warping. If any deterioration is found, create a new vault, transfer your assets to it, and destroy the old materials by burning paper and grinding metal to dust.
Q&A:
I’m trying to install the Pontem wallet, but I only see an option for a browser extension. Is there a mobile app for iOS or Android?
Yes, Pontem has a mobile app, but it’s separate from the browser extension. For the phone version, you need to go to the official website (pontem.network) and find the links to the Apple App Store or Google Play Store. A lot of beginners get confused because they search for "Pontem" inside the Chrome Web Store and assume that’s the only option. The extension is mainly for desktop users who want to interact with DeFi apps on their computer. If you want to use it on your phone, just grab the mobile app directly. Both work fine, but they are two different installations, so you’ll have to set up your wallet separately on each device unless you import using your seed phrase.
