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. The launch addresses a longstanding challenge for blockchain applications: public networks make transactions and contract activity broadly observable, which can complicate their use for financial services that depend on private information. Fhenix is positioning the technology as infrastructure for confidential decentralized finance and tokenization, with the company identifying a potential $1.5 trillion tokenization opportunity currently constrained by privacy limitations.
