Fhenix

Encrypted smart contracts for Ethereum via FHE

Fhenix brings confidential computation to Ethereum using fully homomorphic encryption. Its CoFHE coprocessor lets smart contracts compute directly on encrypted data, so balances, stakes and positions stay private on existing EVM chains. Mainnet goes live on October 21, 2026 on Ethereum and Arbitrum, together with a Dual-Mode Token Standard that switches a token between public and private balances in one transaction, plus five retail apps picked from around 60 applicants. Fhenix has raised $22M from Multicoin Capital, Hack VC, HashKey Capital, GSR, Amber Group and others, and acquired the Sunscreen FHE team in July 2026. A Fhenix token has not been officially announced yet.
