Stacks Labs says it completed first post-quantum sBTC transfer on mainnet

Stacks Labs said it completed the first post-quantum sBTC transfer on the Stacks mainnet, marking a live test of quantum-resistant cryptography for the Bitcoin-linked asset. The transfer used sBTC, Stacks' Bitcoin-backed token, and was executed on mainnet rather than in a test environment. The milestone matters because quantum computing is seen as a long-term threat to the elliptic-curve signatures securing most blockchain assets, and sBTC's design ties Stacks' security claims directly to Bitcoin. Details on transaction size, fees and the specific signature scheme were not disclosed in the article. Next, watch for broader wallet and protocol support for post-quantum signatures and whether Stacks extends the approach to other assets and bridges.
