On October 21, 2026, Fhenix made its confidential computing capabilities available for live use on the Ethereum and Arbitrum networks. This development permits smart contracts to handle encrypted data while keeping the raw information hidden. The announcement coincided with the production release of CoFHE, a coprocessor built for fully homomorphic encryption (FHE). Built upon this foundation, decentralized applications can now perform tasks using sensitive details without revealing account balances, asset positions, or trading plans.
By tackling a persistent hurdle where public blockchains render transaction and contract details widely visible, thereby hindering adoption for finance reliant on private data, Fhenix positions its technology as foundational infrastructure for confidential decentralized finance and tokenization initiatives. The organization calculates that current privacy constraints restrict access to a potential market valued at $1.5 trillion in tokenized assets.
Production Launch Enables Private Smart Contract Operations
Fhenix facilitates the execution of heavy encrypted calculations off-chain, subsequently delivering outcomes to smart contracts deployed on Ethereum and Arbitrum mainnets. The firm notes that its variable throughput scales with user demand instead of capping applications at a fixed processing speed, while simultaneously aiming to ease developer integration via a Solidity import and encrypted data types that behave like standard variables. This methodology permits creators to embed privacy features into current smart contract development routines.
A key element of the launch is Fhenix's dual-mode token architecture, which enables token holders to switch balances between public and confidential modes within a single transaction without wrapping the asset or routing it through a bridge. Fhenix states that because the token stays on its original blockchain, this approach is engineered to maintain compatibility with existing wallets, exchanges, and decentralized finance protocols.
Guy Zyskind, the founder of Fhenix, stated that he could not have anticipated the project's progress when he began it three years ago. He noted that CoFHE is now operational on the Ethereum and Arbitrum mainnets, offering competitive performance alongside a user experience designed to be simple for any builder seeking privacy within their decentralized applications.
Zyskind also mentioned that Fhenix is collaborating with Tandem on a confidential stablecoin, though no further details regarding its development or release schedule were provided in the announcement. The mainnet launch features two initial design partners whose applications demonstrate distinct uses for confidential computation.
Fluton is constructing a confidentiality engine designed to secure interactions across blockchains, applications, and assets through the use of encrypted intents. Concurrently, Alpha Engine is developing a confidential network for onchain finance that allows strategists to submit encrypted strategies and compete for liquidity without revealing their trading approaches. Fhenix confirmed that both projects underwent technical and security reviews prior to going live.
Prior to its release, the platform underwent a security review conducted by Consensys Diligence. The public statement noted that evaluating such environments requires addressing unique risks, specifically those arising when smart contracts process data they cannot directly inspect. The available information did not disclose the specific name or professional title of the Consensys Diligence individual involved.
Steven Goldfeder, who serves as co-founder and CEO of Offchain, observed that organizations have long struggled to balance the need for shielding sensitive financial data with the desire to tap into the composability offered by public blockchain ecosystems. This initiative marks Fhenix's move to tailor public blockchain infrastructure for use cases demanding financial privacy.
Dual-Mode Tokens and Simplified Developer Integration Arrive
Goldfeder stated that confidentiality represents one of the biggest barriers between institutions and public blockchains, as entities need to keep positions and strategies private while utilizing onchain markets. He added that the launch on Arbitrum provides developers with a method to pursue both confidentiality and composability within the ecosystem.
Fhenix intends to broaden the network's application ecosystem over the next few months, with three additional decentralized applications set to debut on CoFHE in the fourth quarter of 2026, alongside plans to reveal two institutional partnerships within the coming weeks. Additionally, the team is joining the Colosseum hackathon to gauge interest in confidential applications built on Solana, which could lead to expanding their research into encrypted computation beyond networks compatible with Ethereum.
