You want self-custody, but you don't want the complexity of a hardware wallet. Tangem solved this: Create a self-custody wallet on your phone for free in 2 clicks. If you later want ultimate security, upgrade to the hardware card without losing your funds. No seed phrase. No recovery codes. No complicated backup.
Today, crypto wallets force a false choice:
Pro: Instant access, easy setup. Con: One phishing link and you're drained. Security is a constant anxiety.
Pro: Ultra-secure. Con: higher upfront hardware cost, 30-minute setup, backup 12-word seed phrase. Overkill for smaller holdings.
What if you could start with a hot wallet's simplicity, then graduate to a hardware wallet's security—without re-importing, re-backing up, or starting over?
Tangem cracked it. You can:
Your mobile wallet's encryption key migrates to the card's secure chip. Your phone erases the key. Same addresses, same funds. Zero gas fees. Zero complexity. You now have a card with hardware-level protection that significantly reduces remote attack surface. (This is the natural path for most people.)
You create a separate wallet on the Tangem card. You transfer funds from your mobile wallet to the card's addresses. (This costs gas and takes more steps—only do this if you want a separate cold wallet for some reason.)
Setup (30 seconds):
No backup required (yet). Your keys live in your phone's encryption layer (Secure Enclave on iOS, StrongBox on Android). Only you can sign transactions. Tangem can't access it. Your phone's OS protects it.
If you upgrade to hardware later: You'll be prompted to create a backup during the upgrade process. You can choose:
Your keys migrate to the card. The card becomes your backup. No mandatory seed phrase workflow for standard card setup. Your family can inherit by tapping the card.
If you want the traditional backup, you can write down a 12-word seed phrase. Then use it to restore on any device. But Tangem doesn't require this.
Tangem's mobile wallet was audited by Cure53, the security firm used by Mozilla, Coinbase, and NordVPN.
The audit confirmed:
Same security audit firm used by Mozilla, Coinbase, and NordVPN. Your keys are genuinely self-custody, encrypted at the OS level.
Month 1: You create a Tangem mobile wallet. You deposit $2,000 USDC. You use it for swaps, Yield Mode, staking—all from your phone. It works great.
Month 6: You've increased to $15,000. You decide you want stronger hardware isolation. You order a Tangem card. It arrives in 3 days.
Day 1 (Card arrives): You tap the card to your phone. The app says "Upgrade wallet to card?" You tap yes. Your key migrates to the card's chip. Your phone erases the key. You now have a physical long-lifespan card holding $15,000 with zero battery, zero internet, zero updates required. Your funds are in the same addresses. Nothing moved. No gas fee.
Year 1-5: You keep your Tangem mobile wallet. You use it daily. You earn yield. You send crypto to friends. You may not feel the need to buy a hardware wallet.
Reality: Your mobile wallet is genuinely secure. Your keys are protected by your phone's OS. Tangem has no access. You're safer than 99% of people using MetaMask.
Cost: $0 to start. Upgrade only if you want the long-lifespan card.
No. The mobile wallet can be secure long-term when device hygiene and recovery practices are strong. Upgrade only if you want physical cold storage or inheritance planning.
Yes, but not with the same wallet. You can create a separate wallet on the card if you want multiple storage layers. Most people just upgrade the mobile wallet to the card (one wallet, one address set, increasing security tier).
No. Zero access. Your keys are encrypted on your device (or card). Tangem sees the same thing everyone else does: your public address and transaction history (which is on the blockchain anyway). They cannot sign transactions, cannot freeze funds, cannot access your recovery phrase.
If you haven't upgraded to hardware yet, you'll need to restore from a recovery phrase (if you created one). If you upgraded to the hardware card, just tap the card to a new phone and restore from the card. Your funds are safe either way.
Mobile: Keys encrypted in your phone's OS. Card: Keys encrypted in a tamper-proof chip. Same security model, different physical location. Mobile is more convenient. Card is more durable (long design lifespan, no battery, minimal updates).
