Fhenix launches CoFHE coprocessor on Ethereum and Arbitrum

The encrypted computation layer lets smart contracts work with hidden balances and positions, starting with a permissioned rollout and five retail apps Fhenix says its CoFHE coprocessor is now running in production on Ethereum and Arbitrum . Smart contracts on both networks can now operate on encrypted balances and positions. According to the project, CoFHE went live on the Ethereum and Arbitrum mainnets on October 21, 2026. The name is short for an FHE coprocessor, with FHE standing for fully homomorphic encryption. Fhenix says developers can tap into this with a single line of Solidity import.
