Fhenix brings encrypted smart contract computation to Ethereum, Arbitrum mainnets

Fhenix has moved its confidential computing technology into production on Ethereum and Arbitrum, allowing smart contracts to process encrypted information without directly exposing the underlying data. The company announced the mainnet launch on Oct. 21, 2026, alongside the production release of CoFHE, its fully homomorphic encryption (FHE) coprocessor. The infrastructure is designed to let decentralized applications execute operations involving sensitive information while preserving the confidentiality of balances, positions and trading strategies.
