Project Eleven Launches Strongpoint for Post-Quantum Custody with Zcash Foundation as Initial Development Partner Zcash Foundation joins Project Eleven to shape institutional custody infrastructure for the post-quantum and AI era as more than $1 trillion in digital assets remain at risk of attack by sufficiently powerful quantum computers. Project Eleven, the post-quantum security company for digital assets, today introduced Strongpoint, its flagship custody platform built for navigating the transition to post-quantum cryptography. @ZcashFoundation joins Project Eleven as an initial development partner, helping shape Strongpoint’s institutional custody architecture. Strongpoint is designed to give institutions a consistent control layer for securing and managing digital assets as networks change the cryptographic standards underneath them. Rather than rebuilding key-management, transaction approval, and audit infrastructure for each new signature scheme or network migration, institutions can maintain a common set of security controls while the underlying cryptography evolves. “Institutional digital asset custody was built for a world where the cryptography underneath it rarely changed,” said Alex Pruden, CEO of Project Eleven. “Quantum computing is upending that model. If every network adopts a different solution, institutions could be forced to rebuild their security infrastructure again and again. Strongpoint is built around crypto-agility, so the cryptography can change without the infrastructure changing with it.” “Institutions holding shielded ZEC need custody infrastructure that respects Zcash’s privacy model today and can adapt as cryptographic standards change,” said Alex Bornstein, Executive Director of Zcash Foundation. “Project Eleven is building Strongpoint with the crypto-agility and technical foundation needed to support those requirements over time, helping strengthen custody infrastructure for the broader ecosystem.” Zcash Foundation Joins as an Initial Development Partner Zcash Foundation joins as an initial development partner for Strongpoint, bringing its expertise in privacy-preserving cryptography and protocol engineering to Strongpoint’s institutional custody architecture. Zcash’s privacy-preserving design introduces sophisticated key-management and transaction requirements, making it a valuable environment for developing custody infrastructure capable of supporting evolving cryptographic standards. The collaboration will help inform how Strongpoint handles network-specific requirements while maintaining a consistent institutional control framework across assets and cryptographic schemes. Post-Quantum Migrations Are Taking Different Paths The digital asset industry’s post-quantum transition is becoming a coordination challenge. Among the networks represented by the 20 largest assets in CoinGecko’s Layer 1 (L1) category by market capitalization, Project Eleven found that only 10 have published a network-specific technical proposal, roadmap or implementation path for migrating transaction or account authentication to post-quantum cryptography. Those approaches span at least six proposed post-quantum signature schemes and vary significantly in how they address account migration, key rotation and legacy-asset recovery. Even where technical roadmaps exist, operational readiness remains uneven, leaving institutions to navigate different standards and requirements across networks. For institutions operating across multiple networks, that fragmentation means accommodating different cryptographic standards and migration requirements without losing a consistent security model. Strongpoint is designed to provide that common operating layer while allowing the cryptography beneath it to change independently. Early Access and Deployment Project Eleven targets production deployment in Q4 2026 and is working with a limited group of development partners ahead of general availability. Additional development partners and supported networks will be announced. Institutions interested in early access can request more information at projecteleven.com/strongpoin…. Founded in 2024 by Alex Pruden and Conor Deegan, Project Eleven raised a $20 million Series A led by Castle Island Ventures in January 2026, bringing its total funding to $26 million. The company recently acquired Riva Labs, a specialized engineering firm with deep expertise in post-quantum signatures, wallet infrastructure and blockchain cryptography, expanding Project Eleven’s in-house research and protocol-engineering capabilities. Methodology: Project Eleven reviewed the 20 largest assets in CoinGecko’s Layer 1 (L1) category by market capitalization on September 25, 2026. A network was counted only where an official network organization, foundation, core development team or recognized protocol-improvement process had published a network-specific technical proposal, roadmap or implementation path for migrating transaction or account authentication to post-quantum cryptography. General research programs, statements of intent and post-quantum work that did not specify such a migration path were not counted. Draft technical proposals were included and do not imply network approval or adoption.

Quantum Vault - An audited reference implementation for account abstraction Post-quantum readiness must be achieved at all layers of the stack. We’ve worked with protocols on post-quantum testnets and hybrid signing models, deployed yellowpages as an attestation service for Bitcoin migration, proposed and optimized PQC algorithms, and proved BIP32 HD Wallets can work in a post-quantum world. Today, we are releasing our latest contribution to the open-source blockchain community: two repositories on GitHub under Project Eleven. Libqc is a TypeScript SDK for ERC-4337 account abstraction with parallel Bitcoin support, and quantum-vault is a browser-extension vault built on libqc. Both are MIT-licensed and have been audited by Cure53. They are reference implementations; not production wallets. Try out Quantum Vault today! ⬇️⬇️⬇️
