AmericanFortress Launches Privacy Infrastructure on Arbitrum for Institutional DeFi

Sheridan, Wyoming, May 28th, 2026, Chainwire

AmericanFortress today announced the launch of the AmericanFortress beta on Arbitrum, introducing a compliant privacy infrastructure designed for institutional and high-volume decentralized finance activity on the Layer 2 network.

The system integration allows users to send assets using human-readable @names while automatically generating stealth addresses that obscure recipient exposure on-chain. The system is designed to preserve auditability between counterparties while avoiding mixers or custodial transaction obfuscation.

Arbitrum currently secures more than $15 billion in total value locked and supports some of decentralized finance’s largest perpetuals and trading ecosystems, including GMX and other high-volume applications. As institutional participation on-chain continues to grow, transaction visibility and wallet transparency have emerged as operational concerns for traders, funds, and automated systems operating in public blockchain environments.

"Financial infrastructure cannot scale institutionally if every transaction exposes counterparties, balances, and trading behavior in real time," said Michal Pospieszalski, CEO and CTO of AmericanFortress. “Arbitrum has become one of the most important execution environments in crypto markets, and this implementation delivers a privacy layer designed for serious financial activity without relying on mixers or compromising compliance requirements.”

The AmericanFortress beta introduces Send-to-Name functionality on Arbitrum, allowing users to transact via FortressNames rather than directly exposing recipient wallet addresses. According to the company, the infrastructure has been designed to maintain compatibility with existing blockchain systems while reducing transaction visibility that can contribute to front-running and trade surveillance.

The launch follows recent cryptographic research published by AmericanFortress detailing a patent-pending post-quantum security architecture for hierarchical deterministic wallets. The company said its wider infrastructure stack combines privacy-preserving transaction systems, naming infrastructure and quantum-resistant wallet security into a comprehensive framework for digital asset custody and settlement.

As part of the launch, AmericanFortress is introducing the “Receive on Arbitrum Privately” campaign, encouraging Arbitrum users to test private receiving functionality through the beta wallet experience. The first 500 eligible participants will receive a lifetime FortressName. The campaign will initially focus on Arbitrum-native DeFi communities, including perpetual traders, liquidity providers, and active on-chain market participants.

"Privacy and usability are increasingly important as more sophisticated financial activity moves on-chain,” said Chase Allred, Senior Partnerships Manager at Offchain, the service provider for Arbitrum. "Infrastructure that improves operational security while remaining compatible with compliant blockchain ecosystems represents an important area of development for the wider industry."

AmericanFortress said the infrastructure is intended to support the next generation of automated financial systems, including AI-driven agents transacting autonomously on-chain. The company believes privacy-preserving execution environments will become increasingly necessary as algorithmic capital allocation and machine-driven trading activity continue to expand across decentralized networks.
