Highlights

Project Eleven and Quantus will launch institutional custody support for Quantus in Q1 2027, enabling hardware-based key management and approvals.
Strongpoint platform lets custodians maintain internal controls and audit trails even as underlying blockchains transition to post-quantum cryptographic standards.
Quantus implements ML-DSA, a NIST-selected post-quantum signature standard, as AI accelerates quantum advances and raises portfolio tail-risk for institutional holders.

Custody integration targets 2027 readiness

As first reported by CoinDesk, Project Eleven and privacy-focused blockchain Quantus plan to add institutional custody support for Quantus in the first quarter of 2027, allowing organizations to manage keys and approve transactions through hardware security modules, internal policies and audit systems.

The companies say the integration is meant to help banks and custodians maintain existing control frameworks as blockchains adopt different quantum-resistant cryptographic standards. The issue extends beyond a single network, because bitcoin, ethereum and other chains may not adopt the same post-quantum signature schemes or migration paths.

Project Eleven’s custody platform, Strongpoint, is designed to separate the institutional control layer from the signature scheme used by an underlying blockchain. That structure means a custodian can keep approval processes, hardware-based key storage and audit trails in place even if a blockchain moves to a different cryptographic standard.

Project Eleven co-founder and CEO Alex Pruden says such a transition could become an impediment to institutional cryptocurrency adoption. He adds that institutions are already preparing for a post-quantum transition outside blockchains to avoid an emergency migration later.

Portfolio risk rises for banks and asset managers

Debate in the crypto sector is intensifying over whether holders should move funds before advances in AI or quantum computing expose wallet keys, but banks and custodians face a more complex challenge in adapting key management, approval and audit systems across several assets. For institutions holding multiple cryptocurrencies, differing security standards could complicate governance without weakening controls over who can approve, sign and review a transaction.

Quantus co-founder and CEO Christopher Smith says AI is accelerating both quantum hardware and quantum software, increasing the urgency of contingency planning. He says the tail risk of a surprise quantum attack needs to be factored into portfolio decisions and treated as part of fiduciary responsibility.

Quantus uses ML-DSA, a post-quantum signature standard selected by the U.S. National Institute of Standards and Technology, for key generation and transaction signatures. Although the timing of quantum computers capable of attacking bitcoin or ether remains uncertain, researchers, developers and companies are increasingly treating the next few years as a window to prepare migration paths rather than wait for a disruptive event.

Our earlier coverage on scam losses in the Philippines highlighted how widespread fraud has become and how heavily it now relies on direct messaging channels such as SMS and chat apps. The report also noted that victims increasingly send money via digital wallets and other instant payment methods, underscoring how operational and security risks around digital asset transfers are rising for users and financial services alike.
