What happened
Trezor CTO Tomáš Sušánka says SHRINCS, the leading post-quantum signature proposal for Bitcoin, is difficult for hardware wallet makers because its stateful option needs precise state tracking to prevent fund theft. Trezor is considering making the larger, slower stateless signatures the default and hiding the stateful option in advanced settings. He also said hardware devices need post-quantum firmware authentication, which the Trezor Safe 7 already supports.
