Project Eleven has introduced Strongpoint, a custody platform designed to help digital-asset operators manage wallets and transaction approvals through the fragmented transition to post-quantum cryptography, with the Zcash Foundation joining as an initial development partner.
The company plans to deploy Strongpoint in production during the fourth quarter of 2026 after a development period with a limited group of partners. The platform is intended to give custodians, funds, protocols and other multi-asset operators one control layer for key management, approvals and audit records, even as blockchains adopt different cryptographic standards.
Project Eleven estimates that more than $1 trillion in digital assets remains exposed to the eventual threat from quantum computers capable of breaking the signature systems used to control many blockchain accounts. Strongpoint’s pitch is less about replacing a network’s cryptography itself and more about helping organizations operate during and after an uneven upgrade cycle.
That distinction places the product in a difficult but potentially useful part of the market. A custodian may hold assets across networks that choose different post-quantum signatures, require users to rotate keys in different ways, or offer distinct procedures for recovering assets tied to older addresses. Each variation could create operational and security risks for firms managing large numbers of wallets.
Zcash Foundation focuses on shielded ZEC custody
The Zcash Foundation will work with Project Eleven on custody support for shielded ZEC, the privacy-focused form of the Zcash cryptocurrency. Shielded transactions obscure information such as the sender, recipient and amount, creating custody requirements beyond those for transparent blockchain accounts.
Custody providers handling shielded ZEC must account for the keys and viewing permissions required to authorize transactions and maintain appropriate records without undermining the asset’s privacy properties. Project Eleven said the collaboration will test whether Strongpoint can support network-specific rules while retaining a common operational model across different digital assets.
The partnership gives Strongpoint an early use case that is more demanding than standard wallet support. A platform that can accommodate shielded transaction workflows may be better placed to address other networks whose post-quantum migrations introduce distinct account models, signing procedures or recovery rules.
Zcash has long been associated with advanced cryptography, making the Foundation a relevant partner for work involving a future change in signature technology. The announcement does not state that Zcash has adopted a particular post-quantum scheme or set a network migration date. Instead, the work centers on how a custody system would support shielded ZEC as cryptographic requirements evolve.
Network migration plans remain uneven
Project Eleven said its review of the 20 largest assets in CoinGecko’s Layer 1 category found that only 10 had published a network-specific technical proposal, roadmap or implementation path for moving transaction or account authentication toward post-quantum cryptography.
The company conducted the review on Sept. 25, 2026. Its methodology counted a network only when an official organization, foundation, core development team or recognized protocol-improvement process had issued a network-specific plan. General research programs, broad statements of intent and unspecified cryptographic work were excluded. Draft proposals counted as published paths, though Project Eleven did not treat them as evidence of approval or deployment.
Among the networks with published plans, the company identified at least six proposed post-quantum signature schemes. Those approaches differ on issues with direct implications for wallet operators: whether existing accounts can migrate in place, when users must rotate keys, how assets locked to legacy signatures can be recovered, and whether old and new authentication methods can coexist during a transition period.
That variety limits the usefulness of a one-size-fits-all custody upgrade. Operators will need to follow each chain’s governance process and technical milestones, then adapt their internal approval systems without creating gaps between old and new wallet infrastructure. Strongpoint is aimed at reducing that operational burden, though its effectiveness will depend on the range of networks it ultimately supports and the details of their eventual migration rules.
Custody becomes part of the quantum-readiness challenge
Post-quantum cryptography refers to cryptographic methods designed to resist attacks from sufficiently capable quantum computers. In blockchain systems, the central concern is that a future machine could derive a private key from a publicly exposed key under certain widely used signature schemes, potentially allowing an attacker to authorize fraudulent transactions.
The timing of such an attack remains uncertain, and major blockchain networks have not moved in lockstep. Some ecosystems have published exploratory proposals or technical roadmaps, while others remain in research or governance stages. For holders of multiple assets, the practical challenge is likely to be managing a series of separate migrations rather than responding to a single industry-wide switch.
Project Eleven’s approach treats custody as a continuity problem. Key policies, access controls, approval processes and audit systems would need to remain functional while the cryptography beneath them changes. A poorly coordinated migration could leave organizations operating parallel wallet systems, relying on manual procedures or exposing themselves to errors during key rotation.
The company was founded in 2024 by Pruden and Conor Deegan. In January 2026, it raised a $20 million Series A led by Castle Island Ventures, bringing its total funding to $26 million, according to Project Eleven. The firm also acquired Riva Labs, an engineering group focused on post-quantum signatures, wallet infrastructure and blockchain cryptography.
Strongpoint’s planned fourth-quarter launch will test whether custody providers want to adopt a dedicated layer for quantum-transition operations before network standards are settled. Early-access requests are available through Project Eleven’s website, while the company continues development with its initial partners.
