According to @deanmlittle, he posted the note Winternitz vaults for solana and linked to a related X post by @aeyakovenko on Oct 30, 2025, source: @deanmlittle on X. Winternitz one-time signatures (W-OTS) are hash-based and regarded as post-quantum secure in standardized schemes such as XMSS and LMS, which are documented by NIST, source: NIST SP 800-208. The post does not provide implementation details, code references, or a timeline for integrating Winternitz-based vaults on Solana, source: @deanmlittle on X. Traders seeking verifiable signals should monitor Solana Labs and Solana Foundation official channels, including public GitHub repositories and core developer communications, for any proposals or commits related to W-OTS vaults before adjusting SOL positioning, source: Solana Labs GitHub and Solana Foundation announcements.
