TL;DR: Fhenix says CoFHE is available on Ethereum and Arbitrum mainnets, giving approved applications a way to perform computations involving encrypted data.
A major weakness of public blockchain applications is that transparency is often the default, even where participants would prefer to keep commercial details private. Fhenix is trying to address that with CoFHE, its fully homomorphic encryption-powered computation system.
The company’s public developer information now describes CoFHE as live on Ethereum and Arbitrum mainnet. Applications can use its coprocessor to work with encrypted inputs instead of revealing every sensitive value to the wider network. That is relevant to private trading, financial positions and other cases where full public disclosure can be a drawback.
The important limitation is access. Fhenix says its early mainnet deployment uses an allowlist for contracts submitting CoFHE workloads, while open testnets remain available for experimentation. Its technical materials also distinguish research throughput measurements from results achieved in live production.
The development doesn’t magically make all Ethereum transactions private. It provides an additional tool to developers prepared to adopt encrypted computation and work within the initial deployment restrictions. If it proves practical under real workloads, confidential finance could move closer to established smart contract ecosystems rather than demanding a wholly separate chain.
