Sui Co-Founder Plans Bulk Quantum Wallet Cards Under $10

Mysten Labs co-founder Kostas Chalkias scales production of quantum-secure Sui wallet cards, targeting sub-$10 costs and 1-2s NFC signing to enhance user security.

Woofun AI reports that Kostas Chalkias, co-founder and chief cryptographer of Mysten Labs, has secured a dedicated factory to mass-produce quantum-secure hardware wallet cards for Sui. The initiative aims to reduce the cost per card key to below $10 while enabling NFC quantum signature processing in 1 to 2 seconds. Chalkias stated he is developing this project independently and may subsidize cards for users with limited funds.

This effort follows the Coldcard incident where a firmware flaw allowed attackers to bypass hardware random number generators, resulting in losses of approximately 2,055 BTC worth nearly $130 million. On the protocol side, Sui intends to integrate two NIST-approved quantum-resistant signing schemes for regular accounts and high-value Move vaults. Users can transition to quantum-secure keys using existing recovery phrases without migrating wallets.
