Project Eleven collaborates with Quantus to provide quantum-resistant support for institutional custody

According to CoinDesk, Project Eleven, which focuses on defending against future quantum computing attacks, and the privacy-oriented proof-of-work blockchain Quantus plan to complete integration in the first quarter of 2027. This will connect Quantus to Project Eleven's institutional custody platform Strongpoint, allowing institutions to manage Quantus keys and approve transactions through hardware security modules, internal policies, and audit systems.

The significance of this integration goes beyond a single chain. Networks like Bitcoin and Ethereum are unlikely to adopt the same post-quantum signature schemes or migration paths. Banks holding multiple assets may need to adapt to various new cryptographic forms simultaneously, without weakening control over transaction approval, signing, and auditing. Alex Pruden, co-founder and CEO of Project Eleven, stated that this transition could become a barrier for institutions adopting cryptocurrencies, as they have already prepared for post-quantum transitions outside of blockchain.

Christopher Smith, co-founder and CEO of Quantus, believes that AI is accelerating everything, including quantum hardware and quantum software. The tail risk of sudden quantum attacks must be incorporated into all portfolio decisions, as it falls under fiduciary duty. The design of Strongpoint decouples the institutional control layer from the signature schemes used by the underlying blockchain. Even if different cryptography is adopted on-chain, custodians can still retain approval processes, hardware key storage, and audit trails. Quantus uses the post-quantum signature standard ML-DSA selected by the National Institute of Standards and Technology for key generation and transaction signing.
