About CrossBar — Company

Security you can see, innovation you can feel.

Founded in 2010, CrossBar pioneers filament-based ReRAM—non‑volatile memory that can live inside your SoC or ship as a standalone device. From chip to wallet, we build security that is open, verifiable, and delightfully usable.

200+ patents Santa Clara, CA Open ethos

Our Vision

Open, community-driven standards for modern wallet security.

Community consortium

Establish an open, community-driven consortium to define and certify modern crypto wallet security standards.

Real-world use cases

Address real-world use cases including MPC-based wallets, cold devices, and mobile-first self-custody.

Transparent by design

Emphasize transparency, reproducibility, and open-source tooling in all certification processes.

ReRAM, reimagined

Compute + storage on one die.

ReRAM enables an all-in-one die solution giving users the utmost confidence in security from the chip level onwards. ReRAM is poised to be a key factor in the future of security with applications from traditional IoT to crypto wallet security.

Embedded or standalone memory—manufactured on standard CMOS lines

PUF‑grade entropy for key material and trust anchors

EMPC: enhanced MPC with hardware‑backed key shares—no single point of failure
