Author: HONKAYOCompiled by: Deep Tide TechFlowDeep Tide Guide: Papertrade bets on replacing LP with "loser losses," launching a perpetual exchange with up to 1000x leverage from a cold start: winners' margins are refunded instantly, and unredeemable profits turn into public debt, replenished by later losers in exchange for PAPER, which is tied to the platform's future earnings. The product's real hard constraint is the payout queue— it can start without external liquidity, but still needs sufficient loss flow to timely pay winners; deposits are set to open on October 8, and trading is scheduled to start on October 10. Before the public contracts and audits are finalized, this model still needs to undergo real volatility testing.TL;DR1000x leverage, no LP, and a queue that pays winners with future traders' losses. Papertrade is attempting to launch a perpetual exchange from a cold start.The protocol will immediately refund the winner's margin, but any profits it cannot temporarily redeem will turn into a public debt. Losing traders replenish the cash pool and receive PAPER—a token tied to the platform's future earnings.This makes the payout queue the core constraint of the product. Papertrade can start without external liquidity, but still needs sufficient loss flow to pay winners on time.This research report is based on information available as of October 3, 2026. Deposits are planned to open on October 8, and trading is set to begin on October 10.How a Papertrade Position WorksPapertrade claims to be a fully on-chain perpetual exchange, with up to 1000x leverage, no funding rates, no slippage, and liquidity pools that can grow from zero. These claims come from the project's initial announcement.From an economic structure perspective, it resembles a casino rather than a typical exchange.On Hyperliquid or Lighter, long and short positions are matched through an order book. Market makers provide liquidity, and traders pay spreads, fees, and funding rates. Papertrade does not match traders against each other. The protocol itself takes on the counterparty for every position.The reference price is provided by Hyperliquid. Papertrade uses the midpoint of its best bid and ask for opening and closing prices, but never hedges on that side. It only records positions, follows the reference price, and settles profits and losses from its own cash pool.The initial market is limited to BTC and ETH. Blurr explained the reason in a founder interview: even the most liquid assets are difficult to manage at 1000x. Faster and better-performing coins might allow traders to withdraw more money from the protocol than what is recovered through liquidation. He mentioned that SOL might reach close to 300x in the future, but that is just a potential future target, not a confirmed market.Positions are per position. Traders cannot use full margin, cannot add margin after opening a position, and cannot close only part of it. The current document sets the single user limit at 10 million dollars, while earlier interviews used 20 million dollars as an example. The final limit will be based on the online contract settings.Leverage is best understood as an integer. Invest 100 dollars, open 1000x, and the nominal value of the position is 100,000 dollars. A price fluctuation of 0.10% results in a profit or loss of 100 dollars, exactly equal to the initial margin. Papertrade expects to liquidate earlier—around a 0.05% fluctuation unfavorable to traders. A few price movements can determine a trade.No funding fees are paid. Blurr believes this is feasible for BTC and ETH because spot and perpetual prices are usually very close. Stocks, gold, and other markets with overnight or weekend closures are more challenging. He directly discussed this limitation in the interview (19:05).Unclear Aspects of "Zero Slippage"Papertrade does not have a local order book, so large orders do not consume multiple price levels layer by layer. Each trade uses the midpoint of Hyperliquid's best bid and ask. This is what the project refers to as zero slippage, although the final payout may still be lower than the original profit.Profitable trades will go through a payout curve. Small fluctuations incur heavier deductions, while large fluctuations are closer to the full original profit. Without this curve, traders could open huge positions and repeatedly extract money from tiny changes in the reference price.A trade might show an original profit of 1000 dollars, but after going through the curve, only 600 dollars are paid out. These are just indicative numbers; actual payouts are determined by online parameters. Blurr mentioned that the team borrowed heavily from Rollbit's mathematical model (23:27).Therefore, "zero slippage" applies to opening and closing price setting, not the final amount received by traders. Before confirmation, the application needs to display the reference price, original profit, post-curve profit, and any queue delays.Fees are not calculated based on position size. In the interview, Blurr described a charge equivalent to 1% of profit and loss (27:15). The contract still needs to specify the exact calculation method and its order relative to the payout curve.Clarifying the Queue Mechanism in Layman's TermsStarting from an empty cash pool.A trader deposits 100 dollars and makes a profit of 100 dollars when closing the position. Papertrade can refund the original margin but does not yet have the additional 100 dollars. The unpaid profit enters the queue.The next trader loses 40 dollars, so the first winner receives 40 dollars first, leaving them with a 60 dollar debt. Another loss of 60 dollars clears this debt. After that, subsequent losses begin to accumulate a positive balance for the protocol.If a second winner arrives before the first debt is cleared, they wait behind in the queue. The queue operates on a first-come, first-served basis.The official risk document allows the cash pool to be negative. Blurr provided a larger example in the interview: if there are 5 million dollars available in the pool but 6 million dollars in profits, the trader first takes 5 million dollars and then waits for the last 1 million dollars.Liquidity risk lies here. Waiting too long can push traders away, and pushing them away also removes the loss flow needed to repay queued debts. The team views the queue as an early safety net and states that the ideal situation is that it hardly needs to be used (23:04).PAPER: Turning Losses into OwnershipPAPER starts with zero supply. The project claims there is no pre-mining, no team or VC shares, no airdrops, and no vesting unlocks. Tokens are only minted when users incur trading losses or are liquidated.The current document states: as long as the cash balance tracked by the protocol remains below 2 million dollars, 100 PAPER will be minted for every 1 dollar lost. Losing 100 dollars will mint 10,000 PAPER.After exceeding 2 million dollars, the minting curve begins to tighten. Its high watermark H tracks cumulative LP earnings above that threshold. The marginal minting rate for each qualifying loss dollar is: 100 × (120M / (120M + H))² PAPER.The curve is extremely biased towards the earliest farmers. When H = 50 million dollars, it is about 50 PAPER per dollar; at 120 million dollars, it drops to 25—by this time, half of the 12 billion tail has been minted. At 260 million dollars, it is about 10, at 420 million dollars it is 5, and at 1.08 billion dollars it is 1. By then, the tail has released 10.8 billion PAPER.12 billion is not a hard cap. It is merely the mathematical limit of the diminishing tail when the high watermark continues to rise. When the tracked LP falls back below 2 million dollars, the flat 100 PAPER/dollar rate will return, thus opening the path to unlimited minting (28:49).The interview had inconsistent exact numbers: Blurr oscillated between 100 and 1000 PAPER per dollar (27:53). The current document states 100, which is a more usable working number
