Sui Developer Mysten Labs Co-Founder Pushes Low-Cost Quantum-Resistant Hardware Wallet

TechFlow news, on August 12, Kostas Chalkias, Co-founder and Chief Cryptographer of Mysten Labs, the developer behind the Sui blockchain, stated that it is advancing the development of quantum-resistant hardware wallet cards for the Sui ecosystem and has rented a factory to support mass production. The product targets a cost of less than $10 per key card and supports Near Field Communication signatures within 1 to 2 seconds.

This plan comes against the backdrop of the ongoing Coldcard hardware wallet firmware vulnerability incident. The vulnerability led to predictability risks in the key generation process of some Bitcoin wallets, and related attacks have caused losses of approximately $130 million. Sui also stated that the protocol layer plans to introduce quantum-resistant signature schemes approved by the National Institute of Standards and Technology to enhance the long-term security of accounts and high-value asset vaults.
