Project Eleven Launches Post-Quantum Custody Platform With Zcash Foundation

Post-quantum security firm Project Eleven has introduced Strongpoint, an institutional custody platform designed to maintain standard control layers while underlying blockchains migrate to quantum-resistant cryptography, the firm announced on Oct. 7 ¹. The Zcash Foundation has joined as an initial development partner to assist in designing the system's architecture, specifically addressing the technical demands of shielded transactions and evolving cryptographic standards ¹.

Strongpoint acts as an abstraction layer for key management, transaction approvals, and audit infrastructure ¹. Rather than requiring custodians to rebuild security operations for every individual signature scheme, the software enables institutions to maintain consistent security policies even as underlying networks implement different post-quantum standards ¹. At the time of writing, Zcash traded at $1,314, down 2.2% over the last 24 hours.

Fragmentation Across Layer 1 Roadmaps

The initiative addresses an emerging coordination gap across major layer-1 protocols ¹. According to an analysis conducted by Project Eleven on Sept. 25, 2026, only 10 of the top 20 layer-1 networks by market capitalization have published technical proposals, roadmaps, or migration paths for quantum-resistant authentication ¹. Across those 10 networks, proposals span at least six different post-quantum signature schemes, presenting divergent strategies for key rotation, account migrations, and legacy-asset protection ¹.

Project Eleven plans to deploy Strongpoint to production in the fourth quarter of 2026 following an early access phase with select development partners ¹. Founded in 2024 by Alex Pruden and Conor Deegan, the firm previously raised a $20 million Series A round led by Castle Island Ventures in January 2026, bringing total capital to $26 million, and recently acquired engineering firm Riva Labs to bolster protocol-level cryptography research ¹.
