Fhenix Mainnet Launch
Fhenix · Releases & Updates · October 21, 2026
Fhenix, the FHE privacy stack for Ethereum, launches mainnet on October 21, 2026, bringing CoFHE and dual-mode public/confidential tokens.
Fhenix, an Ethereum privacy infrastructure project built on Fully Homomorphic Encryption (FHE), launches its mainnet on October 21, 2026 on Ethereum and Arbitrum. The launch brings the CoFHE coprocessor and "dual mode" assets to production: the same token can be held and moved publicly or confidentially, without fragmenting liquidity into isolated privacy pools and without giving up DeFi composability. The mainnet goes live with a first set of apps built on the Dual-Mode Token Standard and follows several years of devnets and public testnets (Helium, Nitrogen). Fhenix positions itself as a quantum-safe privacy stack for Ethereum and EVM chains, targeting confidential DeFi, private payments and RWA use cases.
