Following accusations that the Hyperliquid prices powering its exchange were being manipulated, Papertrade has moved to tighten its trading limits. On October 11, 2026, the platform announced it had started limiting new trading exposure, affecting both onchain activity and transactions routed through relayers that send user instructions to the blockchain.
Key takeaways
- Papertrade’s restrictions target new exposure, not confirmed wallet-specific closing bans.
- Synthetic BTC and ETH trades offer leverage of up to 1000x.
- A cited wallet recorded about $1.28 million in realized trading gains.
- PaperDash showed a $4.30 million pool with no queued payout debt.
According to The Defiant, the platform’s response concerns how much exposure traders can open against its own pool. Its statement does not confirm claims that a particular wallet was blacklisted or prevented from closing positions.
Papertrade’s trading limits target new exposure
The tighter controls apply both to the blockchain contracts and to the approved relayers used during the exchange’s restricted launch. According to the team, unusually loose exposure limits set at launch were behind the alleged manipulation attempts.
Under the rollout plan, users submit trades through the website and approved relayers rather than interacting directly with trading contracts. The plan described transaction ordering as “always indiscriminate of user/account,” while permitting changes to priority weightings.
The published market-freeze mechanism allows existing positions to close using the paused midpoint price. It is not described as a wallet-specific prohibition on closing trades.
How synthetic BTC and ETH trades use Hyperliquid prices
Papertrade offers synthetic BTC and ETH positions with up to 1000x leverage, using the midpoint between Hyperliquid’s highest buying quote and lowest selling quote. The counterparty is a protocol-owned pool, not another trader.
The protocol does not execute a matching perpetual trade on Hyperliquid. Instead, it records the reference price when a position opens and calculates profit or loss against the updated price when it closes.
Crypto.news reported that Boblob (@Dr_bobo54) alleged two wallets placed approximately $20 million each in Hyperliquid trades, moving ETH quotes by 0.1%–0.2%, while holding Papertrade long positions with a combined nominal value in the hundreds of millions of dollars.
That report distinguished Papertrade’s midpoint pricing from Hyperliquid’s own oracle and mark-price systems. Hyperliquid uses its mark price for unrealized profit and loss, margin requirements and liquidations; Papertrade’s synthetic contracts reference the order-book midpoint.
Multisig controls and the money available for payouts
Papertrade’s administrative powers sit with two-of-three multisigs comprising @izebel_eth, @blurr and @UngusTrade. Among the tools available to them are pausing new positions, freezing markets, configuring relayers, and adjusting opening headroom—all measures tied to tightening Papertrade’s trading limits.
Money available to pay profitable trades remains separate from customer collateral. According to administrator @izebel_eth, losses realized by traders go into the pool, whereas profits that cannot be covered right away are placed in a payout queue, with closing a profitable trade returning the trader’s original collateral while only the outstanding gain joins that queue.
This distinction also applies to deposit totals. Ahead of the October 10 opening, DefiLlama tracked approximately $85.3 million in deposits, including both customer balances and the house-side pool, as reported by crypto.news. That figure was not solely the reserve available to pay winners.
PaperDash’s October 11 snapshot put the pool at about $4.30 million, compared with $3.14 million in the earlier report. Both snapshots showed no queued payout debt.
Cited wallet recorded $1.28 million in trading profits
The wallet ending in 840e showed approximately $1.28 million in cumulative realized trading profit on PaperDash. Pseudonymous observer El33 linked the wallet to the alleged strategy; the recorded profit itself does not establish manipulation.
The platform separately said one user had lost almost all earlier profits through new accounts. The cited wallet’s realized gains stood below the approximately $1.73 million recorded in the earlier report, and its dashboard showed no open positions or queued profits.
