- The funding round backs AmericanFortress’s landmark patent filing for quantum-resistant blockchain transactions.
SHERIDAN, WY & DUBAI, UAE – May 5th, 2026 – AmericanFortress™, the builder of the Universal Privacy Layer for blockchain, announced closing its $8m seed round co-led by SAVA Digital Asset Fund, Moon Pursuit Capital, and 0G Labs. Alongside the funding, AmericanFortress™ filed a patent for quantum-resistant cryptographic transaction signing.
The cryptographic foundations of blockchain are under threat and the timeline for that threat has accelerated sharply, with Grayscale Research urgently calling for accelerated efforts to make public blockchains quantum-resistant, noting that decentralized governance, particularly what to do with millions of already-exposed legacy wallets, is the real obstacle.
Every major blockchain – Bitcoin, Ethereum, and the networks built on top of them – relies on elliptic curve cryptography (ECC) to secure wallets and authorize transactions. ECC works because certain mathematical problems are computationally infeasible for classical computers to solve. A sufficiently powerful quantum computer running Shor’s algorithm changes that equation entirely: it can derive a private key from a public key, allowing an attacker to drain any wallet whose public key has appeared on-chain. That is the majority of active wallets in existence.
American Fortress™’s patent filing addresses this directly. The AmericanFortress™ quantum-resistant public derivation scheme is quantum proof signature compatible. For any chain seeking the same protection, AmericanFortress™ will license its quantum-proof signing technology; the company describes it as an easy retrofit. The result: every Send-to-Name™ transaction is quantum-safe end-to-end, and any chain that adopts the technology gains full quantum-proof security, for humans and AI agents alike.
AmericanFortress™ has built the first complete privacy infrastructure for blockchain transactions: human-readable names, stealth address privacy, zero-knowledge balance confidentiality, built-in compliance, and now post-quantum security – in a single system that works across every supported chain.
The seed round will accelerate production deployment of AmericanFortress™’s privacy infrastructure, as well as support the company’s $AF token generation event, targeted for Q2 2026.
“We invented Send-to-Name™ to make crypto as easy and safe as sending a Venmo. Now, with this patent filing, we’re adding a layer of security that protects every transaction against the quantum threat horizon. We’re proud to be the first naming and privacy infrastructure to file for post-quantum transaction signing. Together with 0G, we’re building the infrastructure that the next generation of digital finance actually needs.”
– Michal “MeHow” Pospieszalski, CEO, AmericanFortress™
“At 0G, we’re building the foundational infrastructure for an AI-native economy and that infrastructure must be secure against threats that don’t yet exist at scale but will. AmericanFortress has solved how to make blockchain transactions genuinely quantum-resistant without sacrificing usability, compliance, or privacy. Co-leading their seed round reflects our conviction that post-quantum security isn’t a future feature, but a present necessity. 0G is proud to be the first chain to bring this technology to production.”
– Michael Heinrich, CEO, 0G Labs
The quantum threat to blockchain is no longer theoretical. Google recently published research highlighting quantum vulnerabilities in existing cryptographic schemes, and projects including Circle’s Arc are racing to implement post-quantum protections. AmericanFortress’s patented approach addresses this head-on.
