01 — SHIELDED POSITIONS
Your side never touches the chain
A bet becomes a Poseidon commitment. Only its fingerprint is stored — the Yes/No side, and the link back to you, stay hidden. Two identical bets look nothing alike.
Privacy-preserving prediction markets

A prediction market that's private to place and proven to pay.
Your position is shielded the moment you take it. The whole book is settled by a zero-knowledge proof — so nobody sees your side, and nobody has to trust the house.
The protocol — five guarantees
Everything hidden. Nothing unaccounted for.
02 — PROVEN SOLVENCY
The pool proves it can pay
Before any payout, an SP1 zkVM proves the totals are correct and the book is solvent — computed from every note, revealing none.
03 — NO TRUSTED OPERATOR
Permissionless settlement
Anyone can submit the settlement proof. No admin posts the numbers; the proof is the only authority.
04 — UNLINKABLE CLAIMS
Payouts can't be traced
Winners withdraw with a proof and a one-time nullifier — no double-claims, and no link from payout to deposit.
05 — REAL RESOLUTION
Chainlink decides outcomes
Markets resolve against a live price feed with a staleness guard — deterministic, no discretionary verdict.
How it works — deposit to payout
Four steps. Two proofs.
You escrow ETH and submit a Poseidon commitment to your bet. The chain records a fingerprint, not your side.
Two identical bets produce different commitments, so nothing can be correlated.

Three integrations doing one honest job.
Chainlink CRE
Settled confidentially, proven correct
Node operators sum everyone's private positions inside a TEE and reveal only the totals; an SP1 proof makes that settlement trustlessly correct on-chain. Confidential and verifiable — we keep both.

A risk oracle that refuses to guess
A subgraph indexes only public aggregates — never your position. An AI oracle reasons over it with a pinned deployment and a freshness gate, and benchmarks the book against live mainnet DeFi.

Dollars in, dollars out — cross-chain
Escrow is USDC, and on Arc, USDC is the gas. Bridge USDC from another chain with CCTP and open a shielded position in one journey; winners claim in USDC.
Bet in USDCThe differentiator — verify, don't trust
The totals stay hidden until the proof checks out.
Other markets ask you to trust that the pool adds up. Obscura settles a batch of markets with one zkVM proof. Until it verifies, the numbers are dark.
