What is Fhenix CoFHE?
Fhenix's CoFHE is an off-chain FHE Coprocessor for EVM chains like Ethereum & Arbitrum. It enables privacy-preserving smart contracts with standard Solidity – just 1 line of code. Data stays encrypted during computation, protecting balances, trades & strategies from public view.
Key Features:
- • Fully EVM-compatible – No new VMs or rollups
- • 50x faster decryption than competitors
- • Live on Ethereum Mainnet, Arbitrum & Base
- • Use cases: Private DeFi, confidential votes, encrypted AI
Live Demo: Encrypted Addition
Enter two numbers below. See them "encrypted" (simulated), computed without decryption, then decrypted result. In real Fhenix, this happens on-chain via CoFHE!
How It Works on Ethereum
Encrypt Inputs
User encrypts data with Solidity library & sends to contract.
Emit Event
Contract emits event for CoFHE. Off-chain coprocessor detects it.
Off-Chain Compute
CoFHE runs FHE ops (add/multiply) on encrypted data.
Return Encrypted Result
Result back to chain. Authorized user decrypts via Threshold Network.
Blockchain sees only 🔒 encrypted payloads. Privacy guaranteed!
