Overview
- Papertrade went live Saturday, October 10, 2026, on HyperEVM offering up to 1,000x leverage and drew huge early activity including roughly $14.4 billion in minutes‑level notional volume and about $3 billion in Bitcoin open interest.
- The protocol’s Martingaler house pool started at zero and is funded only by realized trader losses; early on‑chain estimates show about $18 million in net realized trader losses and roughly $10 million to $12.6 million paid to PAPER stakers, while the pool balance sat in the low millions.
- Papertrade prices entries and exits using the midpoint of Hyperliquid’s best bid and offer, which is a single‑venue reference that researchers say can move if large orders hit Hyperliquid’s order book and thus can shift every synthetic position on Papertrade.
- Unverified researcher claims reported that two wallets used roughly $20 million of ETH trades on Hyperliquid to nudge quotes by 0.1%–0.2% while holding large Papertrade positions; Papertrade has begun tightening open‑interest caps but independent proof of a successful exploit, total losses, or a compensation plan has not been confirmed.
- The product’s mechanics — immediate minting of PAPER tokens from losses at high initial rates while the pool is small, queued payouts when the pool lacks funds, and reliance on a single mid‑price feed — amplify settlement and incentive risks and could prompt closer technical and regulatory scrutiny across the Hyperliquid ecosystem.
