Project Eleven and Quantus Partner to Bring Post-Quantum Custody to Quantus Network

Project Eleven and Quantus announced a partnership to integrate the Quantus Network with Strongpoint, Project Eleven's post-quantum custody platform for institutional users ¹. Under the agreement, Quantus joins as a development partner to help guide institutional key management, governance rules, and transaction approval flows across its blockchain ¹.

Quantus is a privacy-focused layer-1 proof-of-work blockchain featuring a 21 million coin supply cap ¹. The network implements Module-Lattice-Based Digital Signature Algorithm (ML-DSA) for generating keys and signing transactions, combined with zero-knowledge proofs for scaling and privacy controls ¹. The integration aims to connect these protocol-level post-quantum protections to institutional operations, allowing organizations to manage Quantus keys via dedicated hardware, policy frameworks, and auditing mechanisms ¹.

Crypto-Agile Infrastructure

The initiative focuses on bridging legacy operational setups with emerging cryptographic standards ¹. Strongpoint utilizes a crypto-agile model that decouples high-level approval controls, key management, and auditing systems from the underlying network-level cryptographic schemes ¹. This design allows institutional teams to interact with evolving signature algorithms without rebuilding their compliance and governance pipelines for individual networks ¹. The partnership follows Project Eleven's earlier deployment work, including its post-quantum custody platform collaboration with the Zcash Foundation.

"Quantus was designed around the security requirements of a post-quantum world," stated Christopher Smith, co-founder and CEO of Quantus, emphasizing that the deployment seeks to lower friction for organizations adopting novel cryptography ¹. Alex Pruden, co-founder and CEO of Project Eleven, noted that institutions will require consistent control layers as alternative blockchains transition toward distinct post-quantum standards ¹.

The teams plan to collaborate on technical support, transaction infrastructure, and institutional key-management workflows leading into the launch ¹. Quantus support inside Strongpoint is scheduled for rollout in the first quarter of 2027, with formal availability dates expected ahead of the release ¹.
