- Fhenix Launches CoFHE on Ethereum and Arbitrum for Private DeFi Transactions — this brief
On October 21, 2026, Fhenix introduced its Confidential Fully Homomorphic Encryption (CoFHE) encryption coprocessor on the 
Ethereum and 
Arbitrum mainnets. This tool allows smart contracts to process encrypted data without revealing sensitive information such as account balances, trading positions, or strategies.
The launch aims to enhance privacy and security in decentralized finance (DeFi) by enabling confidential transactions. This is particularly relevant given the increasing concerns over data privacy and security in blockchain applications.
According to Blockonomi, Fhenix's new dual-mode token design is a key feature of the CoFHE coprocessor. This design allows users to switch between public and private balances in a single transaction, providing flexibility and enhanced privacy controls.
Arbitrum, one of the platforms where CoFHE is now live, has a total value locked (TVL) of $1.47 billion, while Ethereum's DeFi TVL stands at $48.59 billion, according to DeFiLlama. These figures indicate the potential market reach of Fhenix's new tool.
In the broader market context, the total crypto market cap is $2.75 trillion, with 
Bitcoin's price remaining relatively stable at -0.03% in the last 24 hours. Ethereum's price is $2325.7, showing a slight decrease of 0.11% in the same period, while Arbitrum's price has increased by 3.76% to $0.170564.
Since this brief published about 1 hour ago, Ethereum (ETH) has moved from $2,325.70 to $2,333.36 — +0.33%.
The chart plots ETH's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 ETH ≈ ₦3.23M (about $2,333.36), down 0.2% over 24 hours. The naira itself trades about 3.6% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
