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.

Ethereum Up or Down - October 28, 12:00PM-12:15PM ET
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.
