The open stack for private & composable Ethereum execution
Building privacy into Ethereum's native application model. Open specifications. Composable infrastructure. No silos.
The Problem
Privacy on Ethereum is still too fragmented
Many approaches are powerful in isolation, but hard to compose into a shared application model for tokens, DeFi, coordination, and general-purpose contract systems.
Fragmented Liquidity
Current privacy solutions often create isolated pools, breaking composability with the broader Ethereum ecosystem.
Hard to Compose
Private state doesn't flow naturally across applications. Each solution becomes its own silo.
External Services
Privacy is often an external layer—a rollup, a mixer, a separate network—rather than native to the application model.
Private computation should be easier to reason about, easier to build with, and easier to plug into existing sources of liquidity.
On-chain privacy through off-chain computation
We achieve on-chain privacy by leveraging verifiable, private computation executed off-chain. Combined with selective disclosure, applications can maintain privacy while preserving composability and scalability on Ethereum.
Off-chain Execution
Private computation at the edge
Selective Disclosure
Reveal only what is necessary
Verifiable Results
Cryptographic proofs of correctness
Ethereum Native
Composable with existing protocols
Open Source First
Built in the open
Transparent specifications, documented tradeoffs, working code, and reusable components for anyone to learn from, implement, and build on.
Open Specifications
Clear, documented interfaces that anyone can implement.
Transparent Tradeoffs
Every design decision comes with documented reasoning.
Iterative Prototypes
Working code that evolves through public feedback.
Reusable Components
Building blocks others can use in their own systems.
Credibly Neutral Privacy
A credibly neutral privacy layer for Ethereum: open, composable infrastructure that many applications can share—rather than a privacy system tied to a single product, operator, or silo.
