Trezor Weighs Stateless Signatures for a Potential Bitcoin Upgrade

Trezor is weighing a stateless-signature default for its Bitcoin (BTC) wallets if the network adopts SHRINCS, a proposal that could reduce risks from mishandled one-time keys. In that scenario, Trezor is considering making stateless signatures the standard choice and placing the stateful option in advanced settings. The plan responds to the risk of asking users to manage signature state themselves, a task Trezor CTO Tomáš Sušánka said should remain the wallet maker’s responsibility. SHRINCS is a proposed hash-based signature design from Blockstream Research Director Jonas Nick and cryptographer Mikhail Kudinov.
