Project Eleven announced that Quantus has joined as a development partner for Strongpoint, an institutional custody platform designed to support the transition to post-quantum cryptography. The companies plan to integrate the Quantus Network into Strongpoint, with support targeted for the first quarter of 2027.
Strongpoint addresses a specific challenge posed by the potential emergence of quantum-resistant blockchain systems. Different networks are likely to adopt different cryptographic standards on different timelines, requiring different procedures for key migration and transaction authorization. Institutions cannot realistically rebuild their entire security and governance infrastructure each time an underlying blockchain changes its signature scheme.
Crypto-Agility Approach
Strongpoint separates institutional controls from cryptographic implementation. Authentication, transaction approval policies, key management, governance, and audit trails sit in a common control system, while the cryptographic layer beneath can change based on network requirements. Project Eleven calls this approach "crypto-agility."
Quantus will help shape how this architecture functions with a network designed around post-quantum security. The partnership follows Strongpoint's launch with the Zcash Foundation as an initial development partner, allowing the platform to be tested against networks with varying requirements rather than being built around a single chain.
Long-Term Risk Management
Quantum computing remains a long-term risk rather than a present-day threat to existing blockchain cryptography. No known machine can currently extract private keys at scale from major blockchains like Bitcoin.
However, the concern centers on what occurs if sufficiently powerful quantum systems emerge while trillions of dollars in digital assets remain protected by cryptographic assumptions that are no longer trustworthy. Retail holders may eventually move funds to new address types through a network upgrade, but institutional migration is significantly more complex, involving policies, hardware, compliance procedures, signers, approvals, and audit systems that may all depend on existing key architecture.
Custody providers are treating quantum readiness as an operational problem before it becomes an emergency. The Strongpoint and Quantus integration is not yet live, and no immediate quantum threat requires immediate institutional migration. However, this is precisely why the work is proceeding now rather than waiting for cryptography to become urgent.
