PRICE OF BELIEF / SPORTS LEVERAGE SIMULATION
Pick a game. Make your move.
Bitcoin’s next five minutes, the Fed’s decision, oil and gold — and football, the NFL and NCAA. Choose an outcome and go long or short with paper margin at up to 1000× before or during the game. Trade as a guest and keep your liquidation rewards in SLIP. When claiming opens, you claim them with a wallet. No real money.
Play without a wallet. First use each day grants 100 xUSD, and the balance carries over. This browser holds your guest identity; clearing its data may lose access to an unlinked account.
Choose a game. Open a position.
Crypto and finance markets from Polymarket, sports read from Spocal, reference prices from public prediction markets. Go long or short before and during the game at ×1–1000, using xUSD; receive 100 daily, carry over the balance and open multiple positions.
Opens and closes fill at once, at the Polymarket book’s live midpoint at the moment you click, which can differ from the minute-old price on the page; when the book cannot be read or is one-sided, at the next valid quote. P&L is margin × leverage × the price return; losses stop at the margin.
Prices are reference probabilities, not executable quotes. Missing/stale prices, paused games and unknown status block opens. Existing positions wait through outages; finished games close at the next valid reference price, never an invented stale fill.
First use of each JST day grants 100 xUSD; balances carry over and missed days are not backfilled. At most five active positions. Opens reserve margin; closes return remaining margin and net profit.
The platform never takes the other side: winners are paid only from what losers put in. Lost margin flows into the pool; profits are paid out of it, less 10% of each payment (half a platform fee, half to the SLIP reward pool). When the pool is short, the rest is queued and paid as later losses arrive. A position can win at most 1000× its margin; opens stop near settlement (football from 85′, the last five minutes of the 4th, MLB from the 9th, the last minute of 5- and 15-minute crypto windows, the last ten minutes elsewhere). Daily xUSD is simulation issuance, not pool money.
Open positions are marked, and liquidated, on the book price once a minute; the path between minutes cannot be reconstructed, so liquidations are sampled. Opens and closes themselves use the live price at the click.
Losses and liquidations record SLIP rewards at a rate set by the pool: the full ×10 while it holds under 100,000 xUSD (less what it owes), less as it grows; leverage counts up to ×100. SLIP rewards are not pool shares and receive no automatic dividends. They are recorded now; when claiming opens, you claim them by signing in with a wallet. xUSD cannot be redeemed or withdrawn.

SLIP / WALLET
SLIP rewards
Trade without a wallet. SLIP rewards are recorded to your account; nothing to claim yet. When claiming opens, you sign in with a wallet to claim. You can link one now; your history stays.
Recording only; claiming is not open yet. Linking is a signature to prove the wallet is yours — no transaction, no approval.
This is the existing SLIP contract. Simulation rewards and wallet token balances are separate, with no automatic conversion. On-chain claiming is not open yet; when it opens you claim by signing in with a wallet.
