We scan live Polymarket sports events and surface hedge baskets — multi-leg positions across the outcomes of one event — that clear a configurable minimum-EV filter. You pick which basket to take. You sign each leg in your own wallet. We forward the signed orders to Polymarket.

The engine is deterministic. Same event, same prices, same config → same basket. There is no machine learning predicting outcomes; the math is about exploiting the overround that Polymarket's order book exposes.

Direct betting picks one outcome. A hedge basket spreads across multiple outcomes of the same event, structured so the cost of the basket is below the guaranteed payout from any single winning position. You give up potential upside on a single big win in exchange for materially lower variance.

Non-US Polymarket users who already understand how prediction markets work and want a tool that does structured, mathematical position-building rather than picks or signals. If you're looking for tips on which team will win, this is not the right product.

No. There is no deposit, no withdrawal, no on-platform balance. Your USDC and CTF tokens live in your Polymarket account on Polygon throughout. We sign orders against them; we never move them.

We use it to forward your already-signed orders to Polymarket's order book on your behalf. The L2 key authenticates the HTTP request; the signed order itself is what authorises any actual position change. Without your EIP-712 wallet signature, the L2 key alone cannot place, cancel, or move anything.

Encrypted at rest with libsodium secretbox (XChaCha20-Poly1305), one nonce per field, master key held in Infisical. The plaintext only enters server memory for the microsecond it takes to attach an HMAC header to one of your order submissions. Never logged, never persisted.

No. Every order placement requires a fresh EIP-712 signature from your wallet — a MetaMask prompt that shows you the exact order being placed. If you stop signing, nothing gets traded.

We use Fill-Or-Kill order type, which means each leg either fills in full at the price you signed or doesn't fill at all. The basket math depends on every leg landing; partial fills would break it. If a leg can't fill, it comes back as failed on /app/positions and the other legs that did land are available to cancel.

Click Cancel next to the order on /app/positions. Polymarket cancellations don't require a fresh wallet signature — they go through the L2 API and are usually instant. Cancellations cost no gas.

For most accounts (Polymarket proxy or Gnosis Safe funder), Polymarket sponsors gas through their Relayer when an order carries a Builder code — and ours does. For plain EOA accounts, you pay Polygon gas yourself, which is usually a fraction of a cent.

NBA, NFL, MLB, NHL, soccer, tennis, League of Legends, CS2, Valorant, Dota 2. The engine picks up any event Polymarket tags with those sport codes.

Defaults are min $50 and max $100 per basket, configurable in /app/settings. The maximum is also capped by the depth available on each leg — the engine walks the live order book and won't propose a basket that would walk prices past the slippage budget you set.

Per-trade fees would create the wrong incentive — we'd be motivated to push you toward more (and more marginal) baskets. A flat subscription pays the same whether you execute zero baskets or fifty. The engine is rewarded for being right, not for being noisy.

It's priced for the user who's placing enough volume that the engine pays for itself many times over, while staying low enough to feel reasonable for someone running a few hundred dollars in baskets per month. If that's not your volume profile, hedgehog is probably the wrong tool.

We deployed an immutable Solidity contract on Polygon — HedgehogSubscription— that anyone can read. You give it permission to pull $90 USDC every 30 days. You can cancel any time on-chain; cancellation stops future pulls but doesn't refund the current period. The contract address is on /app/subscription.

Yes, five days from your first sign-in. No card / no wallet authorization required to start. You can run scans and look at baskets during the trial; the subscription contract only activates when you click Subscribe.

We don't do partial refunds — once a monthly pull completes you have access for that period. If you cancel, your subscription stays active until the period ends, then doesn't renew. If there's ever an issue with a charge, email hello@hedgehog.bet and we'll sort it.

No. Polymarket's Terms of Service exclude US persons, and hedgehog inherits that restriction — we're a layer on top of Polymarket, not a replacement for it. If you can't legally use Polymarket, you can't usefully use hedgehog.

No. We're an independent third-party app participating in Polymarket's public Builder program. Polymarket has not endorsed, audited, or vetted us.

No. The engine surfaces positions that look favourable given the prices on the board; that's not the same as a prediction or a recommendation. Markets reprice, strategies fail, you can lose your stake. Manage risk accordingly.
