MiningStore + Tangem
Tangem is a self-custody hardware wallet built around NFC cards, simple mobile onboarding, optional seed phrases, and everyday usability.
The primary button goes to the company’s official website.
Key Facts At a Glance
These are the details MiningStore thinks matter most when evaluating fit, traction, and proof.
Tangem says it was founded in Zug, Switzerland in 2017.
The homepage currently says zero out of 6,000,000 cards have been hacked since launch.
Official help pages cite an EAL6+ chip plus 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.
- The company is trying to make hardware custody feel less intimidating for normal users 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's homepage publishes a 6,000,000-card adoption figure and states zero cards have been hacked since launch in 2017.
- The official help center cites an EAL6+ secure element and firmware audits by Kudelski Security in 2018 and Riscure in 2023.
- Tangem's March 2026 mobile-wallet post says the companion app also passed an independent Cure53 audit.
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.
