Fhenix has launched its mainnet on Ethereum and Arbitrum, putting its CoFHE fully homomorphic encryption coprocessor into production. The setup is designed to let smart contracts work with encrypted data while still keeping rule enforcement onchain.
According to the project, the system is aimed at use cases where balances, positions and trading strategies need to remain private without removing blockchain-based verification. The launch also introduces a dual-mode token feature that allows assets to move between public and confidential states in a single transaction.
Encrypted computation with onchain verification
Fhenix said its mainnet allows smart contracts on Ethereum and Arbitrum to execute operations on encrypted data directly. The goal is to preserve confidentiality for sensitive information while maintaining the logic and enforcement mechanisms that normally happen onchain.
To make that possible, the platform offloads the most demanding encrypted computation offchain and then returns verified results to the smart contract. Fhenix described the design as having dynamic throughput, with the coprocessor handling the heavy processing while onchain contracts receive outcomes that can still be enforced by network rules.
Privacy features aimed at DeFi use cases
The company said the system can keep account balances, market positions and trading strategies private. A central feature is its dual-mode model, which lets token balances switch between public and confidential modes within the same transaction.
Fhenix said this can be done without wrapping or bridging assets. That distinction matters because it allows privacy controls to be added without introducing a separate token representation or moving funds across another network layer.
Early partners and audit work
The initial ecosystem around the launch includes two design partners. Fluton is described as an encrypted cross-chain transaction engine, while Alpha Engine is positioned as a network for encrypted trading strategies and liquidity.
Fhenix also said Consensys Diligence completed a technical audit of the system. According to the project, the audit affirmed that contracts can clear transactions involving unseen numbers while still producing outcomes that can be verified.
Institutional interest and expansion plans
The launch comes with a broader push toward confidential decentralized finance applications. Offchain Labs CEO Steven Goldfeder said CoFHE addresses institutional privacy needs in DeFi, highlighting the demand for systems that can protect sensitive trading and portfolio data while preserving blockchain execution guarantees.
Looking ahead, Fhenix said it plans to deploy three additional decentralized applications on CoFHE in the fourth quarter and expects two institutional partnerships in the coming weeks. The company also said a confidential stablecoin is being developed with Tandem.
What comes next
Beyond Ethereum and Arbitrum, Fhenix said it will join the Colosseum hackathon to explore confidential applications on Solana. That effort suggests the company is testing whether its privacy-focused model can extend beyond the two networks where the mainnet has now gone live.
For now, the confirmed next steps are the planned Q4 dapp launches, the expected institutional partnerships and continued development of the stablecoin project with Tandem. Those milestones should provide the clearest indication of how quickly encrypted smart contract applications move from infrastructure into active use.
