Tangem launches version 2.0 with some serious upgrades. Word is Saylor just picked one up himself.

The standout feature? They're calling it the world's first EMP-proof cold wallet ring. That electromagnetic pulse resistance is no joke—basically designed to survive scenarios that would brick most hardware wallets. They've also baked in zero-day protection, which addresses vulnerabilities that haven't even been discovered yet.

The form factor is interesting too. Moving beyond the traditional card design into a ring format could appeal to users who want something more wearable. Tangem's second-generation cards are hitting the market now, and the timing with institutional players like Saylor showing interest suggests the custody hardware space is heating up again.

Whether the EMP-proof claim holds up under real stress testing remains to be seen, but it's definitely positioning itself as a bunker-grade solution for serious holders.
