Fhenix and Canopy have announced a technical partnership to integrate confidential computation directly into the Canopy Stack, enabling developers to build sovereign onchain applications that preserve user data encryption throughout processing. The collaboration eliminates the need for development teams to assemble a standalone cryptography stack or hire specialist cryptographers before deploying private application logic.

At the core of the integration is a new Canopy Confidential App template powered by Fhenix's CoFHE coprocessor, which handles fully homomorphic encryption. Fully homomorphic encryption, or FHE, is a cryptographic technique that allows mathematical operations to be performed on ciphertext without decrypting it first — a capability long considered a milestone goal in cryptography research. Developers can incorporate encrypted computation using a TypeScript library, embedding confidentiality into applications from the ground up rather than retrofitting it as an add-on. The integration extends Canopy's existing platform model, where the stack manages underlying infrastructure so builders can focus on application development.

While public-by-default infrastructure serves many onchain use cases well, it falls short when applications handle commercially sensitive, personal, or strategic information. The visibility of all transaction data on public networks has been a recurring barrier to enterprise and institutional adoption of blockchain technology. Some teams have retreated to closed networks in response. Fhenix and Canopy propose a different approach: maintaining network openness while keeping data encrypted across its entire lifecycle.

Technical Architecture, Deployment Status, and Application Scenarios

The architecture operates through Canopy's plugin and runtime layer without modifying base consensus. A user's input is encrypted within the Canopy wallet and submitted as a standard transaction. Fhenix's CoFHE system then processes the encrypted data offchain. When a result needs to be disclosed, a trust-minimized mechanism returns a signed value that Canopy verifies before settling state. Developers access this workflow through familiar tooling without managing a separate privacy stack or encryption keys.

Several of Canopy's core components are already operational, including plugin lifecycle hooks, the state bridge, plugin scaffolding, and the wallet runtime. Fhenix has deployed CoFHE across Ethereum, Arbitrum, and Base. Development of the remaining encrypted-transaction components is ongoing.

The architecture supports concrete applications across multiple sectors. In an onchain game, a player's hand, units, and map knowledge can remain hidden — participants submit moves privately and learn only the outcome, such as who prevailed, how much damage was dealt, or which territory changed control.

The same model extends to business workflows. A buyer can issue a request for proposals, receive encrypted bids from multiple suppliers, and publish only the winning bid and price once the deadline closes. Unsuccessful bids remain private and are never exposed to other participants.

"Every team we talk to hits the same wall. They have a real use case, and it requires not publishing their users' data to the world," said Adam Liposky, CEO of Canopy, in a written statement. "Until now the answer was to hire a cryptographer. Now it's a plugin."

"Open networks should not require open data. By bringing CoFHE into the Canopy Stack, developers can build sovereign apps that compute on sensitive information while it stays encrypted," said Guy Itzhaki, CEO of Fhenix, in a written statement. "Confidentiality becomes part of the application architecture, not a separate system teams have to build around."

The Fhenix integration is currently under development and scheduled for release in the fourth quarter of 2026. Canopy is live on public testnet, where it has recorded 16,800 forks and maintains over 100,000 daily active wallets.
