How it works

Four steps. Zero trace.

01 / 0401

Deposit privately

Move USDT or USDG into the shielded pool. You get a secret note that only your device holds. Every deposit looks identical.

02 / 0402

Pick a round

BTC, ETH, BNB or SOL. 5 minutes, 10, 15, an hour or a day. Will the price close higher or lower?

03 / 0403

Bet with a proof

Your browser proves you own funds in the pool without saying which. A relayer submits it, so your wallet never appears.

04 / 0404

Settle and vanish

The oracle settles the round. Winners split the pool and claim to any fresh address, or roll winnings into the next round.

Markets

Always a round about to close.

Four assets, five timeframes: 20 rounds running at all times, aligned to the clock so everyone sees the same countdown.

Privacy

Public odds. Private traders.

On a normal market, every bet is a billboard: whales get copied, winners get front-run, and your history follows your wallet forever. Primar uses zero-knowledge proofs and a shielded pool, so the market sees liquidity, not people.

Pooled payouts

No house on the other side. Winners split the losing side, minus a 2% fee. One-sided rounds refund everyone.

Oracle settled

Start and end prices come from Pyth and Chainlink feeds. Anyone can trigger settlement, so rounds never get stuck.

Two chains, one app

Same contracts on BNB Chain and Robinhood Chain. Switch networks without leaving the board.

Fair cutoffs

Betting closes before the end of every round — 1 minute for 5m, up to 1 hour for daily — so nobody bets on a known answer.
