Mission
Why I Build This
I believe financial privacy is a fundamental right, not a feature.
Every blockchain transaction today creates a permanent trail, your salary, subscriptions, donations, everything is public.
That's not transparency, that's surveillance.
My goal is not to build a product, it's to build an ecosystem.
Mobile app, browser extension, developer SDKs.
Every layer covered.
One person, zero compromises.

Scope
What One Dev Can Build
On-Chain Infrastructure
- Solana programs in Anchor and Rust
- Shielded pool with a STARK-gated unshield
- On-chain STARK verifier over Goldilocks, FRI included
- Registry, relayer and fee-splitter programs
Client Applications
- Mobile app in Expo and React Native
- Chrome extension on MV3
- This web app, on Next.js 16
- Merchant SDK demo and documentation
Privacy Layer
- Stealth addresses: X25519 + ML-KEM-768 (FIPS 203)
- Denominated notes in one shielded pool
- p01_relayer, which submits the transaction on the payer's behalf
- A deposit can still be matched to the withdrawal that spends it
Quantum Resistance
- Proofs from Poseidon and Merkle trees, no elliptic curves
- Winternitz one-time signature vault (WOTS+)
- Hash-timelock vault
- Transaction signatures stay Ed25519: Solana verifies nothing else
