A per-trade fee makes us want to push you toward more baskets — even marginal ones. A flat subscription pays the same whether you execute zero or fifty. The engine is rewarded for being right, not for being noisy.
The subscription contract on Polygon is immutable and public. It can only pull the fixed monthly amount on a fixed cadence, never more. You can cancel() from a block explorer if our website is down. There's no Stripe dashboard we can use to charge extra.
Polymarket lets builder apps charge a per-trade fee on the orders they route. We attach our builder code (for attribution + gasless trading via their Relayer) with the maker and taker fee fields both set to zero. The full Polymarket spread goes to whoever matched against you.
Users placing enough Polymarket volume that the engine pays for itself many times over — typically a few hundred to a few thousand dollars in baskets per month. If your volume is below that, hedgehog is probably the wrong tool. Email us before subscribing if you're unsure.
