Trader Rune: PaperTrade's document mentions the risk of BBO price manipulation at the agreement level

X platform user Rune pointed out that PaperTrade official documents revealed the risk of "loopholes" in its agreed pricing mechanism. According to a screenshot of the document provided by Rune, attackers can implement price manipulation through BBO (Best Bid Price) in the Hyperliquid order book. This risk is related to unfixed contract economic mechanisms, risk exposure control flaws, insufficient operational protection measures, and rights management loopholes. In addition, Rune forwarded a tweet from community member boblob, revealing that two suspected offensive wallets were conducting large-scale transactions on the PaperTrade platform, causing abnormal fluctuations in ETH prices on the Hyperliquid platform through a transaction size of approximately US$20 million.
