Fhenix
Fhenix is a fully homomorphic encryption (FHE) coprocessor that brings private computation to EVM chains, starting with private DeFi.

What is Fhenix?
Fhenix is an FHE coprocessor designed to add confidential computation to EVM-based applications. Developers write Solidity contracts that call out to Fhenix to do math on encrypted inputs, private DeFi balances, sealed-bid auctions, confidential voting, without exposing the underlying values. It plugs into Arbitrum and other EVM chains as a coprocessor rather than a standalone L1.
