Back to collectionFhenix Opens CoFHE Mainnet on Ethereum and Arbitrum
The launch gives allowlisted developers production access to encrypted computation without moving applications to a separate chain.
Fhenix announced on October 21 that CoFHE is live on Ethereum and Arbitrum mainnet. Developers can add encrypted types and operations to existing Solidity applications, while a distributed offchain network performs the fully homomorphic encryption work and returns verifiable results to the chain. Fhenix says launch access is permissioned through an allowlist.
The release is production infrastructure for selected developers, not a claim that all application state becomes anonymous. Fhenix’s own explanation distinguishes encrypted computation from full privacy: surrounding metadata and application design can still expose information. The main development is that teams can test confidential logic against mainnet contracts without migrating to a dedicated privacy chain.
