For users
Reveal less, retain more privacy, and avoid repeatedly sharing raw credentials.
What We Build
Composable privacy infrastructure.
Turn trusted credentials and private conditions into minimal, EVM-verifiable statements for people, applications, and autonomous agents.
Private input

For services
Collect and store less sensitive data while still verifying the condition an action requires.
Don’t store sensitive data better. Avoid receiving what you never needed.
Proof Portals
One infrastructure. Distinct proving paths.
Browser, mobile, and managed agent proving use the same open proof core. Agent proving remains a distinct TEE-based trust model.
Human / Browser
Web proof runner
A browser-based interface for supported proof generation and EVM verification flows, designed to be invoked by applications through the SDK.
Human / Local
Mobile proving
Supported flows generate proofs on the user’s device with React Native, mopro, and Noir / UltraHonk. Private witness data can remain on device for these flows.
Built on mopro from Ethereum’s Privacy & Scaling Explorations ecosystem.
Agent / TEE
Programmatic agent proving
An agent should not need your full identity. It may only need to know whether KYC passed, a country is allowed, an organization matches, or an asset threshold is satisfied.

Architecture
From trusted data to usable proof.
CIPs define proof semantics, circuits implement them, and EVM verifiers make the result composable inside applications and agent actions.
STEP 01
Trusted data
Private data enters the flow under an explicit trust model.
Human path · local
A person selects a trusted credential or private condition in the web or mobile experience.
AI agent path · TEE
An agent sends an end-to-end encrypted request; sensitive inputs are handled inside the configured TEE boundary.
private data→verified predicate→composable action
Coinbase EAS + Base
Coinbase / EAS → ZKProofport private proof → application / agent
Existing Coinbase EAS credentials become privacy-preserving predicates that applications and agents can verify and act on.
Composable Conditions
KYC ✓ + Country ✓ + Balance ≥ X (future) → eligible action
Proofs can become conditions for access, agent actions, payments, and possible future trade, RWA, or financing flows.
Open Source + Security
Inspect the proof. Not the promise.
The open-source privacy stack is live today. Broader consumer distribution is intentionally controlled while privacy-critical components are hardened and prepared for independent review.
Live today: open-source Noir circuits, Base Mainnet and Ethereum Sepolia verifiers, published SDK and MCP packages, and independently inspectable deployment records.
