ZUG, Switzerland, August 4, 2026 (Chainwire) — Casper, the Layer 1 blockchain designed for regulated real-world assets and the machine economy, and AmericanFortress, the company behind quantum-proof, compliant privacy infrastructure for existing blockchains, have announced a strategic technology partnership to integrate AmericanFortress's security and privacy stack into the Casper ecosystem.

The partnership covers four key areas:

Quantum-safe wallets. Casper plans to adopt ZKPoSP, AmericanFortress's newly published post-quantum zero-knowledge scheme for hierarchical deterministic wallets. This complements the quantum-safety initiative already underway under the Casper Manifest. ZKPoSP is designed to protect existing accounts before quantum computers become a practical threat, with no address migration and no user action required.

Zero-knowledge compliance infrastructure. Every shielded transaction will carry a zero-knowledge proof of sender, enabling Know Your Transaction (KYT) capability and Travel Rule readiness without exposing user identities. This selective-disclosure architecture mirrors what institutions already require from traditional finance rails. It also addresses a tension that has challenged the broader crypto industry: how to offer transaction privacy without creating tools that regulators flag as money-laundering vectors. By embedding compliance proofs directly into shielded transactions, the design aims to let regulators verify origin and legitimacy without exposing participant identities — a balance rarely achieved in production blockchain privacy systems.

Cross-chain naming interoperability. The companies will explore interoperability between AmericanFortress's FortressNames and Casper's established CSPR.name on-chain naming system. The initial integration will support named destinations in Casper's forthcoming cross-chain bridge, allowing users on either platform to send to a human-readable — and potentially fully confidential — name rather than a raw address.

Built for Regulated Real-World Assets

The partnership directly targets Casper's core market: regulated real-world asset tokenization. As a member of the ERC-3643 Association, Casper is delivering the first non-EVM implementation of the compliant tokenization standard and participates in the T-REX Ledger, the institutional reference infrastructure for compliant tokenization. For issuers and institutions bringing regulated instruments on-chain, confidentiality combined with auditability and cryptography designed for decade-plus asset horizons are prerequisites rather than optional features. This partnership addresses both requirements within a compliance framework that institutions already recognize.

The timing aligns with accelerating institutional interest in tokenized real-world assets. Major financial institutions — including BlackRock, Franklin Templeton, and JPMorgan — have launched or piloted tokenized funds and settlement systems over the past two years, and industry analysts project the RWA tokenization market could reach trillions of dollars in value over the coming decade. As that market matures, the infrastructure layer beneath it faces growing scrutiny: instruments such as private equity, real estate, and debt funds require confidentiality for competitive and legal reasons, yet regulators expect the same level of traceability that applies to their off-chain counterparts.

Quantum Safety Without a Second Migration

Casper is uniquely positioned to adopt quantum safety ahead of the broader industry. The protocol natively supports multiple cryptographic key algorithms — currently both Ed25519 and secp256k1 — a flexibility most blockchains lack. ZKPoSP's curve-agnostic key-derivation scheme, QBIP32, works uniformly across both, meaning the entire Casper account base qualifies for quantum protection without exception.

The approach is designed for long-term durability. Early post-quantum signature schemes typically force users onto new address formats, and if those relatively young algorithms are later found to be vulnerable, users face yet another migration. ZKPoSP instead relies on well-studied hash functions and zero-knowledge techniques that run in parallel with existing signatures. Users retain their addresses, keys, and funds permanently.

This matters because the cryptocurrency industry has lagged behind traditional finance in post-quantum preparedness. While NIST finalized its first post-quantum cryptography standards in 2024 — selecting CRYSTALS-Kyber and CRYSTALS-Dilithium after a multi-year global evaluation — most blockchains still rely on elliptic-curve signatures that sufficiently powerful quantum computers could break. The concern is not immediate, but "store now, decrypt later" attacks — where adversaries harvest encrypted data today for future decryption — mean that assets with long time horizons are exposed to threats that have not yet materialized.

"Institutions tokenizing real-world assets need confidentiality that regulators can audit and cryptography that outlives the assets themselves," said Michael Steuer, President and CTO of the Casper Association. "AmericanFortress delivers both without forcing anyone to migrate. Their non-mixing architecture means privacy that chain analysis can still verify — exactly what regulated finance requires. And because Casper natively supports multiple key algorithms, we can adopt quantum safety across our entire account base well ahead of the curve, without requiring users to move. That is how it should be done."

"Casper built the chain institutions actually need for real-world assets — deterministic finality, upgradeable contracts, and compliance embedded at the protocol level through standards like ERC-3643," said Michal Pospieszalski, CEO of AmericanFortress. "AmericanFortress built the privacy and quantum-security layer those same institutions require. Our SDK drops into the Casper stack with no migration, and every account on Casper can be quantum-proof before Q-Day rather than after. Casper is exactly the kind of forward-looking ecosystem this technology was built for."

The technical foundation for the quantum-safety pillar is detailed in the paper "ZKPoSP: Post-Quantum Zero-Knowledge Proofs for Hierarchical Deterministic Wallets," which was published to the IACR ePrint archive on July 21. The paper introduces a split-proof architecture that secures existing wallets against quantum attackers with no address migration, no protocol changes, and no user action required.

Integration milestones will be announced through official Casper and AmericanFortress channels in the coming months.

About Casper

Casper Network (CSPR) is a Layer 1 Proof-of-Stake blockchain engineered for regulated real-world assets and the machine economy. With deterministic transaction finality, a multi-VM execution layer supporting both WebAssembly and soon EVM smart contracts, and fixed-cost operations enforced at the protocol level, Casper delivers the infrastructure for compliant asset tokenization, frictionless consumer experiences, and autonomous machine-to-machine commerce.

The Casper Manifest — the network's multi-year technical roadmap — advances nine coordinated protocol initiatives spanning developer access, user experience, institutional compliance, privacy, micropayments, and quantum safety.

The Casper Association, a non-profit organization based in Zug, Switzerland, oversees protocol development and ecosystem growth.

About AmericanFortress

AmericanFortress builds quantum-proof, compliant privacy infrastructure for the blockchains institutions already use. Its drop-in SDK — powered by two patented technologies, the Confidentiality Machine and FortressNames — delivers private, compliant, quantum-safe transactions with no migration required.

Headquartered in Jackson Hole, Wyoming, AmericanFortress has raised over $9 million and holds a portfolio of 14 patents granted, allowed, or pending across privacy transactions, zero-knowledge identity, custody, and quantum-proof cryptography. The company has won five consecutive international pitch competitions, including first place at Token2049 Dubai and Bitcoin 2025 Las Vegas. Its partners include MetaMask, whose Snap integration places the technology within reach of more than 30 million monthly active wallets, along with 0G, LitVM, and others.
