What is the Tandem Wallet?
Before we begin the setup, let’s understand what the Tandem wallet is. The Tandem wallet is a hardware wallet designed like a physical card, akin to a credit card. It utilizes NFC (Near Field Communication) to interact with your smartphone. This card securely stores your private keys offline, which significantly reduces the risk of hacking. Unlike traditional USB hardware wallets, such as Ledger or Trezor, Tandem does not require any cables or a computer, making it a fully mobile-native solution.
Unboxing the Tandem Wallet
When you receive your Tandem wallet, it typically includes two or three physical Tang cards (depending on your package), a user guide, and a QR code to download the Tandem application. Alternatively, you can visit the official website to download the app. Each card is identical and acts as a backup for the same wallet, providing convenience and redundancy.
Setting Up the Tandem Application
- Download the Application: Get the Tandem app from the App Store or Google Play Store.
- Open the App: Launch the application on your smartphone.
- Create a Wallet: Tap on the ‘Create Wallet’ button.
- Scan Your TAM Card: Hold your first TAM card to the back of your smartphone to initiate the NFC scan. Ensure that your phone’s NFC feature is enabled.
- Secure Wallet Generation: The application will automatically generate a wallet address and key pair securely within the card after the scan. Notably, the private key does not leave the card at any point, offering increased security.
Activating Backup Cards
After your main card is activated, the app will prompt you to scan each backup card individually. Once added, all cards are equal, meaning you can use any of them to access your wallet at any time. If you lose one card, you can still use another. However, if you lose all cards, your wallet becomes unrecoverable. Therefore, it’s essential to store them safely.
Securing Your Wallet
Tandem employs a unique security approach, eliminating the need for a password or PIN unless you choose to enable one for app access. If you’re concerned about physical theft, consider using an app like App Lock to secure the application.
Your Tandem cards are designed to be waterproof, tamper-resistant, and shockproof. For maximum security, store your cards separately and enable biometric security features like fingerprint or Face ID on your phone.
Sending and Receiving Crypto
To receive crypto on your Tandem wallet:
- Navigate to the App: Open the Tandem application.
- Select Your Asset: Choose the cryptocurrency you want to receive (e.g., Bitcoin).
- Receive Funds: Click on the ‘Receive’ button and copy your wallet address. Paste this address in the crypto wallet or exchange (like Robinhood or Coinbase) from which you are sending funds.
Note: Since the private key signs the transaction directly on the card, no sensitive data touches your phone.
Supported Assets and Networks
Tandem supports over 6,000 tokens across more than 30 blockchains, including Bitcoin, Ethereum, Polygon, Solana, Binance Smart Chain, and Avalanche. The list is constantly updated, so be sure to check the app for the most recent assets.
Recovery Plan for Tandem Wallet
Unlike traditional wallets that utilize recovery phrases, Tandem employs a multi-card redundancy system. If you selected two cards during setup and lose one, you still have a backup. If you have three cards, you can lose one and remain secure. It’s important to note that you must have at least one functioning card for recovery; this setup protects against phishing attacks and cloud hacks.
