Why Steal

Privacy that actually settles on-chain.

Confidential lending where the math is public and your numbers are not.

Hidden by default

Collateral, debt, and credit scores live on-chain only as Poseidon commitments. The raw numbers never touch the ledger.

Proven, not revealed

Zero-knowledge proofs (Noir + UltraHonk) attest a position is healthy — without exposing a single value.

Client-side proving

Every proof is generated in your browser via WASM. Private inputs never leave your device.

Auditable on demand

Share a view key and an auditor can decrypt the full position. Nobody else can — not even the pool.

Settles on Soroban

Proofs are verified on-chain on Stellar. Confidential, but fast and cheap to settle.

How it works

Borrow without showing your hand.

Four steps, from commitment to settlement — all confidential.

01

Commit privately

Deposit collateral and set a credit score. Only Poseidon commitments go on-chain — never the amounts.

02

Prove in your browser

Generate a zero-knowledge proof that your position is healthy — locally, in WASM. Nothing sensitive leaves your device.

03

Borrow in the dark

Draw USDC against your collateral. The chain sees a valid proof and a commitment — never how much.

04

Liquidate or audit blindly

Liquidators prove a position's health factor is below one without seeing your numbers; auditors decrypt with a view key.

Built with

A zero-knowledge stack, end to end.

Proven in Noir, verified on Soroban, driven from the browser.
