How the fee works

Takers pay fee = feeRate × min(price, 1−price) × shares, charged in USDT. It's symmetric around 0.50, so the closer the price is to a coin-flip the more you pay in absolute terms, while the effective % of your money grows as the price gets cheaper. Makers pay nothing. There's a $1 minimum order value. A 10% discount, when active, just multiplies the fee by 0.9.

Fees you've actually paid to predict

Paste a wallet and pick a window — it reads your on-chain fills and sums the real fees you paid across all predict exchanges. Addresses only, read-only.

Addresses only — never a private key or seed phrase. Reads public on-chain data; it can't move funds and never asks for a key. A very active wallet over a long window may be capped by the time budget (it'll say so).
