Private finance
on any chain.
StealthOS gives the wallet you already use a private balance. Send, receive, swap, and trade — all invisible to others. Every transaction is proven in zero knowledge and verified on-chain.
Connect your wallet, approve one signature and your private wallet is ready.

Fully private.
Still verified.
Every payment carries a zero-knowledge proof that the chain checks before anything settles. It proves the funds exist, are yours and add up, without revealing the sender, the recipient or the amount.
Proven on your device.
Verified on-chain.
StealthOS uses a shielded UTXO model with Groth16 zero-knowledge proofs, on every network it runs on.
Shield
Every deposit becomes a UTXO: a cryptographic commitment recorded in an on-chain Merkle tree.
Prove
To spend, your device generates a Groth16 proof that the UTXOs exist, that you’re authorised and that value is conserved, without revealing which UTXOs or who owns them.
Verify
StealthOS verifies the proof on-chain before any state changes. A unique nullifier per spend means no UTXO is spent twice.
Non-custodial
At no point does StealthOS take custody of your funds.

Privacy Policy
Last updated: March 2026
StealthOS is built on the principle that financial privacy is a right. This policy explains how we handle information when you use our platform.
1. Information We Do Not Collect
StealthOS does not collect, store, or transmit your private keys, spending keys, or shielded note data. Proof generation can occur entirely client-side in your browser.

By design, StealthOS obscures on-chain transaction details including balances, amounts, and participant identities using zero-knowledge proofs. Only constant-size commitments are published on-chain.
3. Analytics & Cookies
This website may collect anonymised usage analytics (e.g. page views) to improve the product. No personally identifiable information is linked to analytics data.
4. Third-Party Integrations
Institutional deployments may include third-party wallet screening providers for compliance purposes. Any data shared with such providers is governed by their respective privacy policies.
5. Data Security
We implement industry-standard security practices. However, no system is completely secure, and we cannot guarantee absolute security of information transmitted to our platform.
6. Changes
We may update this policy as the platform evolves. Material changes will be communicated via this page.
