CrossBar Inc.

We’re now live on X. CrossBar is building secure, verifiable hardware — from ReRAM-based memory to open-source crypto systems. From silicon to firmware, every layer matters. We’ll be sharing regular updates on our progress, insights into our technology, and introductions to our products. Visit our website: crossbar-inc.com

Our Chief Business Officer, Elaine Wang, and VP of Product & Business Development, HP Ong will speak at Network School to explore how open silicon, ReRAM, and MPC can eliminate hardware backdoors and protect user assets end-to-end. 🗓 May 5, 2026 🕓 3:00 PM – 4:00 PM (GMT+8) 📍 NS Library, Forest City Marina Hotel, Jalan Forest City 1, Pulau Satu, 81550 Gelang Patah, Johor, Malaysia We’ll share our work with the Ethereum Foundation, demo our hardware wallet, and host a live Q&A.

“Open-source” hardware isn’t really open. Most systems expose the surface— but hide the critical security layers. That’s where the real risks live. CrossBar is changing that. #OpenSource #HardwareSecurity #CryptoSecurity #Web3 #Blockchain #Ethereum #HardwareWallet #CyberSecurity #Trustless

🤝Great connecting at Network School! Our Chief Business Officer Elaine Wang met Balaji Srinivasan (@balajis) at Network School —exchanging ideas on the future of crypto, hardware, and decentralization. Building what’s next, together. #Network School #Networking #Innovation #TechCommunity #Crypto #OpenSource #Web3 #Hardware #Innovation #Singapore

CrossBar applied for Ethereum Security QF Round on Giveth. 🚀 Open source hardware wallet — from chip to app 🔓 No more black-box security. Just verifiable self-custody. Built for Ethereum。 ReRAM-powered. Support us👇 giveth.io/project/crossb… #Ethereum #OpenSource #CryptoSecurity

Self-custody is supposed to be trustless. But today’s reality: 🔒 Black-box hardware 🐞 Hidden vulnerabilities 👤 Unknown trust assumptions If you can’t inspect the hardware, you don’t truly own your keys. #CryptoSecurity #SelfCustody #Web3 #Blockchain #HardwareWallet #OpenSource

🔥A full room. Engaged audience. Big questions about crypto’s missing layer. 👥On April 17 at Network School, our Chief Business Officer Elaine Wang and VP of Product & Business Development HP Ong shared the vision for open-source hardware—starting from the chip itself. 🌹Great to see such thoughtful questions and discussion from the community. #Crypto #NetworkSchool #Web3 #CryptoSecurity #Builders
