We’ve been in talks with Offchain Labs, the people behind Arbitrum and one of the most cracked teams in the crypto space, on how to solve for encryption in Ethereum.

At Fhenix, our mission is to make encrypted computation a first-class primitive onchain. Today, we’re proud to announce a major milestone in that journey: CoFHE is now live on Arbitrum Sepolia.

Mid-2025 check-in: Fhenix is shaping up to be the backbone of encrypted computation on Ethereum. We’re all-in on making FHE the go-to standard for onchain confidentiality. Here’s a look at what we’ve shipped lately — and a sneak peek at what’s coming next as we keep building the Confidential DeFi layer for Ethereum.

Fhenix integrates FHE so smart contracts can compute directly on encrypted data without decryption, keeping data private throughout processing.
