Paperhands has no outside liquidity. The house is funded only by the losses of its traders, and it starts at zero.
Every loss mints paper to the trader who took it: a share of the house that cannot be transferred. Half of every fee and all the surplus above the reserve go to paper holders. The other half of each fee goes to the treasury.

//03_ The queue lineFig.03
Winners the house cannot pay yet wait in line.
When the house holds less cash than a winner is owed, the profit is queued, first in, first out. Every later loss pays the line before anything else, and a claim is paid only once every claim ahead of it is whole.
The margin always comes back at once. Only profit waits.

//04_ One price per tradeFig.04
One price per trade, chosen by nobody.
A request fills at the first 10 second RedStone price after it is made. You cannot see that price when you ask, and the keeper cannot pick another: the contract accepts exactly one timestamp per request.
Anyone can execute a request with that signed price, you included.

//05_ The marketsTab.05
Eleven markets.
Bitcoin and Ether trade around the clock, up to 100x. Nine US stocks trade up to 50x while the New York market is open, 09:30 to 16:00 on NYSE trading days. Positions stay open overnight and on weekends.
//Impact_curve_keep = 0.9 / (1 + 1/(move x 15,000) + 100,000/(1e6 x move x pm))
Gains pass through an impact curve that keeps more of a large move than of a small one. On BTC a 1% move keeps 88.3% of the gain and a 0.1% move keeps 75.7%. Losses are never scaled.
//07_ The paper curveFig.07
Early losses buy more of the house.
Below $25,000 of house equity, every dollar lost mints 100 paper. Above it the rate falls as (S / (S + H))², with S at $1,500,000 and H the equity above the threshold.
A high-water mark holds the rate down once it has fallen, so it never climbs back when the house shrinks.
//08_ RisksPlain words
What can go wrong.
R.01
Leverage
At 100x a move of 0.95% against you loses the whole margin. A bust is final, even if the price comes back a second later.
R.02
The queue
When the house is short, the profit of a winning trade can wait in the line for a long time. It is paid only from later losses and donations.
R.03
The oracle
Prices are signed by five RedStone signers and three are enough. A compromised signer set could post a wrong price inside the 2.5% Chainlink band.
R.04
The keeper
Requests and liquidations need someone to execute them. The keeper does it; if it stops, anyone can, but nobody is obliged to.
R.05
The contract
Smart contracts can contain bugs. This one has no upgrade path, so a bug cannot be patched in place.
R.06
Overnight gaps
Equity positions stay open while the stock market is closed. A stock can open far from its last price, beyond your bust price.
A share of the house, recorded in the contract against your address. It is minted only to traders who lose, on the amount they lost. Paper earns half of every fee charged and all of the surplus above the reserve.
Q.02Can I sell or send my paper?
No. Paper is a ledger entry, not a token. It cannot be transferred, so it cannot be sold. What it earns is claimable in USDG at any time.
Q.03What happens when I win and the house cannot pay?
Your margin comes back at once. The profit joins the queue line and is paid, first in first out, from the next losses and donations. Collect it from the app when it is paid.
Q.04Why does my order not fill instantly?
Every request fills at the first RedStone price published after it, on a 10 second grid. Nobody can see that price in advance, so nobody can trade against the delay. Expect 2 to 12 seconds.
Q.05Do I own the stock?
No. A position is a synthetic exposure settled in USDG. There is no share, no dividend and no vote behind it.
Q.06What does one-click trading do?
Your wallet authorises a key generated in this browser, for at most 30 days, and sends it a little ETH for gas. That key can open and close positions for you and nothing else. Revoke it at any time.
Q.07Who can change the rules?
The owner can add markets, adjust their parameters inside hard limits, pause new opens, retire a market and set the signer set. Nobody can move user balances, claims or rewards. The contract is not upgradeable.
Q.08Is there a fee to deposit or withdraw?
No. You pay the chain its gas, and Paperhands charges fees only when a position closes.
