AmericanFortress has rolled out a beta privacy layer on Arbitrum aimed squarely at institutional and high-frequency DeFi users — promising mixer-free transaction shielding that keeps counterparties private while preserving auditability between participants.
What it does
- The system introduces a Send-to-Name flow using human-readable FortressNames and auto-generated one-time stealth addresses. Users can send assets to an @name; behind the scenes the protocol creates a unique stealth address so on-chain observers cannot easily link flows to persistent wallet strings. Counterparties retain cryptographic access to transaction records, enabling bilateral auditability without exposing balances or trading behavior to third parties.
- AmericanFortress bills FortressNames as “the first human-readable, send-to-name wallet and secure transaction infrastructure for digital assets,” designed to replace fragile wallet strings with one-time, quantum-resistant addresses. The company also says its cryptographic design includes a patent-pending, post-quantum security architecture for hierarchical deterministic wallets.
Why Arbitrum?
Arbitrum has emerged as one of Ethereum’s dominant Layer 2s for DeFi, making it an attractive place to target institutional trading and liquidity activity. According to an Arbitrum Foundation transparency report, the network processed more than 2.1 billion cumulative transactions in 2025, with total value locked (TVL) hovering near $20 billion and almost $10 billion held in stablecoins. Major perpetual venues like GMX have long anchored derivatives liquidity on Arbitrum — Bitquery found GMX held more than $450 million in TVL on Arbitrum V2 by early 2024, and prior reporting showed GMX has generated millions in daily fees (one day in January 2023 produced $2.74 million).
Positioning: privacy as operational risk management
AmericanFortress frames the product as a tool for operational security rather than secrecy. “Financial infrastructure cannot scale institutionally if every transaction exposes counterparties, balances, and trading behavior in real time,” CEO and CTO Michal Pospieszalski said, calling Arbitrum “one of the most important execution environments in crypto markets.” The beta is designed to be compatible with existing systems and to blunt vectors such as frontrunning, copy trading and surveillance that exploit address-level visibility.
Rollout and incentives
As part of the launch, AmericanFortress is running a “Receive on Arbitrum Privately” campaign inviting Arbitrum traders, liquidity providers and market makers to test private receiving flows via the beta wallet. The first 500 eligible participants will receive a lifetime FortressName — a permanent handle that anchors their send-to-name identity on the network. The initiative is targeting Arbitrum-native communities where address-level privacy is especially sensitive.
Industry reaction and roadmap
Offchain’s senior partnerships manager Chase Allred described the combination of privacy and usability as a growing need: infrastructure that boosts operational security while remaining compatible with compliant blockchain ecosystems is “an important area of development for the wider industry.” AmericanFortress says the stack couples privacy-preserving transaction rails, naming infrastructure and quantum-resistant wallet security into a broader custody and settlement framework designed for automated finance, including AI-driven agents that will transact autonomously in DeFi.
Why this matters
As algorithmic capital allocation and machine-driven trading expand, AmericanFortress argues that privacy-preserving execution environments will be necessary to protect sensitive strategies and counterparties — and to keep institutional participants comfortable moving bigger pools of capital on-chain. For Arbitrum, the launch bolsters its evolution toward institutional DeFi alongside other integrations like Chainlink oracles and yield-bearing stablecoins, and it highlights privacy as a competitive battleground among Ethereum Layer 2s.
The beta is live on Arbitrum now; AmericanFortress is inviting qualified participants to try the system and claim early FortressNames as part of the campaign.
