Real words from real wallets.
From first unboxings in the mountains to Tangem Pay in the wild, our community keeps showing us what self-custody looks like in practice.
Thank you for the feedback, the photos, and the trust. Keep them coming🖤

What EAL Certification Guarantees and What It Doesn't
If you've compared hardware wallets, you've seen EAL ratings used as selling points. EAL6+ implies the highest security standard achievable. The ratings are real. The certification process is rigorous. The chips that carry these labels have genuinely been…

Tangem Pay runs on Polygon. Gas is free during the launch for all users. 💰
Most crypto cards liquidate your holdings through a custodian before the transaction even reaches the payment network. With Tangem Pay, your USDC stays in your wallet until the moment of payment. Settlement happens onchain, in real time.
We built on Polygon for three reasons: speed, cost, and scale. Fast finality + predictable fees = self-custody payments that work at everyday frequency. No waiting, no surprise costs. As a result, your crypto actually feels like money.
Eligible users in the US, Latin America, and select Asia-Pacific countries can activate a virtual Visa card directly in the Tangem app.

Secure Elements explained by people who break chips for a living
Secure Elements are embedded in hardware wallets, passports, payment cards, and SIM cards. They come with certifications and assurance levels that imply near-invincibility. However, a growing body of hardware security research tells a more complicated story.…

A lecture at Neu-Ulm University of Applied Sciences this week 🇩🇪
Wallets, keys, and what self-custody actually means in practice. Every student in the room left with a Tangem in hand to try it for themselves.
Theory is one thing. Holding your own keys is another.
