Fhenix and Canopy integrate confidential computation to simplify private onchain app development.
Summary
- Fhenix and Canopy integrate confidential computation, enabling developers to build privacy-preserving onchain apps with encrypted data.
- The two projects have launched a confidential app template, bringing fully homomorphic encryption to sovereign blockchain applications.
- Fhenix brings encrypted computation to the Canopy Stack, simplifying confidential onchain app development with familiar tooling.
Fhenix and Canopy are integrating confidential computation into the Canopy Stack, giving developers a direct way to build sovereign onchain apps that keep user data encrypted while it is being used. The integration removes the need for teams to assemble a separate cryptography stack or hire specialist cryptographers before they can ship private application logic.
The new Canopy Confidential App template is powered by Fhenix’s CoFHE coprocessor for fully homomorphic encryption (FHE). Developers will be able to add encrypted computation through a familiar TypeScript library, making confidentiality part of the app from the start rather than a feature added later. The approach extends Canopy’s existing platform model: the stack handles the underlying infrastructure so builders can focus on the application.
Public-by-default infrastructure works for many onchain use cases, but it breaks down when applications handle commercially sensitive, personal, or strategic data. Some teams respond by moving to closed networks. Fhenix and Canopy are taking a different approach: keep the network open while keeping the data encrypted.
Confidential operations are added through Canopy’s plugin and runtime layer without changing its base consensus. A user’s input is encrypted in the Canopy wallet and submitted as a standard transaction. CoFHE processes the encrypted data offchain, and when a result must be disclosed, a trust-minimized process returns a signed value for Canopy to verify before state is settled. Builders access the flow through familiar tooling, without managing a separate privacy stack or encryption keys.
The core Canopy components are already live, including plugin lifecycle hooks, the state bridge, plugin scaffolding, and the wallet runtime. CoFHE is currently deployed across Ethereum, Arbitrum, and Base. Work on the remaining encrypted-transaction components is in progress.
What it enables
In an onchain game, a player’s hand, units, and map knowledge can remain encrypted. Players submit moves privately and learn only the outcome of each encounter, such as who won, how much damage was dealt, or which territory changed hands.
The same model applies to business workflows. A buyer can open an RFP, receive encrypted bids from multiple suppliers, and publish only the winner and winning price at the deadline. The losing bids do not need to be revealed to the other participants.
The Fhenix integration is in development and is scheduled to roll out in Q4 2026. Canopy is currently live on public testnet, with 16.8k forks and more than 100,000 daily active wallets.
