Fhenix Brings Encrypted Smart-Contract Computing to Existing EVMs
Fhenix is developing a coprocessor that lets smart contracts process encrypted data while remaining compatible with existing EVM chains.
Fhenix is developing a coprocessor that lets smart contracts process encrypted data while remaining compatible with existing EVM chains. This is an original TLT brief based on reporting by Brave New Coin, with live market data added, as of Mon, 09 Nov 2026 05:45:02 UTC.
The approach could extend privacy-preserving computation to applications already deployed on EVM networks without requiring users or developers to migrate to a separate blockchain. It also connects Fhenix’s work with broader efforts to bring fully homomorphic encryption into practical systems.
- Fhenix’s CoFHE coprocessor targets smart contracts across existing EVM chains.
- Encrypted computation is presented without requiring migration to a new chain.
- CEO Guy Itzhaki previously led Intel’s FHE and blockchain initiatives.
- Bitcoin fell 1.57% over 24 hours as Fear & Greed registered 29.
Brave New Coin profiled Fhenix and its fully homomorphic encryption technology, describing a CoFHE coprocessor designed to let smart contracts on existing EVM chains calculate over encrypted data. According to the report, Fhenix’s approach does not require users to move their activity or applications to a new blockchain.
Fhenix CEO Guy Itzhaki has extensive experience in confidential computing and encryption infrastructure. He spent much of his career at Intel, where he helped bring the SGX and TDX trusted execution environments to market and later led initiatives involving fully homomorphic encryption and blockchain. Before joining Fhenix founder Guy Zyskind to launch the company three years ago, Itzhaki also worked as a technology adviser for the Tokyo and Paris Olympic Games.
The sole available account comes from Brave New Coin, which presented Fhenix as extending encrypted computation to established EVM environments rather than introducing a standalone execution chain. No second outlet was supplied to independently confirm the technical claims, corporate background or product positioning, and no token, user count, deployment figure or commercial result was provided.
The wider crypto market was broadly lower at the time of the report. Total market capitalization stood at $2.56T, 
Bitcoin was down 1.57% over 24 hours, and the Fear & Greed index registered 29, corresponding to Fear. No Fhenix-linked coin was included in the supplied market snapshot, so the available data does not show an asset-specific market reaction. The development is significant for its proposed mechanism: encrypted information could be processed by compatible smart contracts without exposing the underlying data or requiring a chain migration.
Fhenix Brings Encrypted Smart-Contract Computing to Existing — questions & answers
What does Fhenix’s CoFHE coprocessor enable?
It lets smart contracts on existing EVM chains compute over encrypted data, according to Brave New Coin. Users would not need to move to a new chain for that functionality.
Who leads Fhenix and what is his background?
Guy Itzhaki leads Fhenix. He previously worked at Intel on SGX and TDX, led FHE and blockchain initiatives, and advised on technology for the Tokyo and Paris Olympic Games.
What was the broader crypto market backdrop?
Total crypto market capitalization was $2.56T, Bitcoin was down 1.57% over 24 hours, and the Fear & Greed index stood at 29, indicating Fear.
