How PolyYard Works — Decentralized Prediction Markets on Polygon

What Is PolyYard?

PolyYard is a non-custodial, multi-venue trading terminal. From one screen you can discover and monitor markets across three venues:

• Polymarket — on-chain prediction markets on Polygon, tradable directly from PolyYard.
• Kalshi — regulated US event contracts (live data and charts; order entry coming soon).
• Hyperliquid — perpetual futures with up to 50x leverage (live data and charts; order entry coming soon).

How Prediction Markets Work

Each market asks a verifiable question, and every outcome trades between $0.00 and $1.00. A price of 72¢ means the market estimates a 72% chance. When the event resolves, winning shares redeem for $1.00 each and losing shares expire worthless.

Many events offer multiple outcomes — for a football match you may see "Liverpool wins", "Draw", "Over 2.5 goals" and more. PolyYard lists every outcome the venue offers so you can pick exactly the contract you want.

The Terminal

Everything happens in the Terminal:

1. Venue tabs — switch between Polymarket, Kalshi and Hyperliquid.
2. Watchlist — search and browse live markets, sorted by 24h volume.
3. Outcomes panel — browse all contracts of the selected event and choose Yes/No on any of them.
4. Contract rules — the official resolution rules from the venue, updated as you change market or outcome.
5. Pro chart — candles or line view, 15m to 1D intervals, zoom in/out, SMA, EMA, Bollinger Bands, RSI, plus horizontal and trend-line drawing tools.
6. Live order book — real-time bids, asks, spread and feed latency.
7. Blotter — your positions, trade history, risk overview and referral rebates in one place, with Excel export.

Non-Custodial Wallets

Sign in with an external wallet (MetaMask, Coinbase, Trust, OKX, Rainbow and more) or with email/social login, which creates a secure self-custodial wallet for you. Every account uses a dedicated Polymarket deposit wallet that you control — PolyYard can never move your funds. Trading actions such as wallet setup and approvals are gasless.

Funding

Use the Deposit button in the header to move USDC.e from your wallet to your trading wallet with 0% fees. Withdrawals go back to your connected wallet at any time.

Transparent Fees

Every Polymarket order carries a 50 bps fee: a 20 bps builder fee and a 30 bps PolyYard markup, plus any market fee set by Polymarket. All fees are shown in the order ticket before you sign. The minimum order is $10.

Getting Started

1. Connect a wallet or sign in with email.
2. Deposit USDC.e into your trading wallet.
3. Open the Terminal, choose a market and outcome.
4. Place an order — Buy or Sell, Limit or Market — and sign in your wallet.
5. Track positions and P&L in the blotter below the chart.
