Next-gen hardware wallet tech just dropped.

TANGEM's second generation card brings three major upgrades: EMP-proof construction, fully open-sourced architecture, and private keys that stay completely isolated. Zero-day attack protection built in from day one.

What changed? The new hardware design hardens against electromagnetic pulse interference while maintaining the same card-form factor. Transparency matters—everything's auditable because it's open source. Your keys never touch the internet. Period.

Current promotion runs through January 29th. New TANGEM V2.0 cards are priced 20% lower with the applied code, plus you get an extra $10 worth of BTC on top. That's the kind of incentive that makes upgrading from older hardware wallets actually worth the hassle.

If you're serious about cold storage and want something that doesn't require a hardware hub or recovery phrase risks, this shifts the conversation.
