Ethereum Builders Live, the community conference focused on Ethereum infrastructure, will feature a dedicated discussion on the PQ1 — a new post-quantum hardware wallet. The session is set to explore how the device could help secure crypto assets against the eventual arrival of powerful quantum computers.
What is the PQ1?
The PQ1 is a hardware wallet built with post-quantum cryptography. Unlike traditional wallets that rely on elliptic-curve signatures, the PQ1 uses algorithms designed to resist attacks from quantum machines. The device is still in its early stages, but the team behind it plans to demo the hardware and walk through the cryptographic choices during the event.
Why post-quantum matters now
Quantum computing isn't here yet, but the crypto industry is already thinking about the transition. If a large-scale quantum computer ever breaks current signature schemes, funds stored in standard wallets could be at risk. Post-quantum hardware wallets like the PQ1 are one proposed solution — they let users store keys in a format that quantum algorithms can't easily crack. The discussion at Ethereum Builders Live will likely cover the timeline, the trade-offs in speed and cost, and whether the ecosystem is ready to adopt new signature standards.
The PQ1 session is scheduled for the second day of Ethereum Builders Live, which runs from August 12–14 in Denver. No firm release date for the wallet has been announced, but the talk could give developers and users a clearer sense of when post-quantum hardware might hit the market. For now, the conversation is about awareness — and making sure the next generation of wallets doesn't get caught off guard.
