Sui Co-Founder Leases Factory to Mass-Produce Quantum-Safe Hardware Wallet Cards, Targeting Key Cost Below $10 Per Card

Odaily News: Kostas Chalkias, co-founder and chief cryptographer of Mysten Labs, the development company behind the Sui blockchain, stated that he has leased a dedicated factory at a secret location and plans to scale up production of quantum-safe hardware wallet cards for Sui. The project aims to keep the cost of a single quantum card key under $10, with NFC quantum signing expected to take 1 to 2 seconds.
Chalkias noted that the project is being advanced in his personal time outside of work and may include funding to provide cards for users who cannot afford them. The initiative is partly driven by a recent incident involving Coldcard hardware wallets, though the vulnerability was not a quantum attack.
Coldcard manufacturer Coinkite disclosed that a firmware vulnerability in Coldcard, traceable to a 2021 update, bypassed the hardware random number chip and generated keys using a predictable software process linked to device serial numbers. Attackers have been moving funds since July 30, with losses climbing to approximately 2,055 BTC, affecting over 7,700 addresses and nearing a value of $130 million.
At the protocol level, Sui plans to integrate two quantum-resistant signature schemes approved by the U.S. National Institute of Standards and Technology (NIST), designed for everyday accounts and high-value Move vaults, respectively. Existing accounts can be rotated to quantum-safe keys based on their original recovery phrases, without needing to migrate to new wallets. (Bitcoin.com News)
