MiningStore + Tangem
Tangem is a self-custody hardware wallet built around NFC cards, simple mobile onboarding, optional seed phrases, and everyday usability.
Key Facts at a Glance
Tangem launched in Zug, Switzerland in 2017.
Tangem has shipped 6,000,000 cards and reports zero hacked since launch.
Tangem secures the wallet with an EAL6+ chip and independent audits from Kudelski, Riscure, and Cure53.
Tangem markets a 25-year limited hardware warranty and a tap-to-use workflow with no cables or batteries.
What They Do
- Tangem provides offline self-custody through NFC cards and a mobile app that lets users manage Bitcoin and other assets from a simple tap-based flow.
- Tangem makes hardware custody feel less intimidating by stripping out cables, desktop setup, and extra maintenance.
- Its wallet experience supports seedless backup by default, with an optional seed phrase for users who prefer a more traditional recovery model.
Problems They Solve
- Many miners and first-time holders know they should leave exchange custody but delay it because the wallet setup feels too complex.
- Traditional hardware wallets can feel slow, cable-heavy, or intimidating for people who want a more mobile-first routine.
- Seed phrase management is a real failure point for new users who understand the risks of custody but are not ready for a highly technical workflow.
Why They’re Unique
- Tangem centers the user experience on NFC tap-to-sign interactions, which lowers the friction of actually using self-custody day to day.
- The wallet is seedless by design while still letting advanced users enable a seed phrase if they want one.
- The product emphasizes portability and durability in a form factor that feels more like a card than a desktop device.
Social Proof & Signals
- Tangem has shipped 6,000,000 cards and reports zero hacked since launch in 2017.
- Tangem uses an EAL6+ secure element and has published audits from Kudelski Security, Riscure, and Cure53.
- Tangem's companion app passed an independent Cure53 audit in March 2026.
Best Fit For
- Miners and Bitcoin buyers graduating from exchange custody into a hardware wallet.
- Users who want a simple mobile-first custody flow with less setup overhead than a traditional device.
- People who care about portability and like the idea of a card-based hardware form factor.
Why MiningStore Recommends Tangem
- Mining helps people accumulate BTC, but the strategy is incomplete if the coins stay on someone else's platform.
- Tangem lowers the barrier for MiningStore clients who know self-custody matters but have postponed the transition.
- It is a practical bridge between convenience and sovereignty for a lot of newer long-term holders.
