PaperTrade tightens controls after manipulation attempts on Hyperliquid price feeds

PaperTrade has responded to manipulation attempts on Hyperliquid's best-bid/offer (BBO) prices, which are used for synthetic execution of BTC and ETH trades. The manipulation affected ETH quotes, prompting PaperTrade to tighten open-interest limits both on-chain and via relayers to enhance security. This incident raises concerns about PaperTrade's reliance on external price feeds and its exposure controls, though Hyperliquid's native system remains secure. Market watchers will be focused on PaperTrade's upcoming token launch and any further security measures to restore investor confidence.

PaperTrade's recent tightening of controls after manipulation attempts on Hyperliquid's BBO prices is contextually set against a mixed market breadth on Pluang, where 30 of 50 major cryptocurrencies rose and 19 fell as of Oct 21, 2026 21:43 WIB. Among notable movers, SXP dropped sharply by 46.27% to Rp37, contrasting with BAL which gained 11.14% to Rp16,297, while BAT fell 14.45% to Rp3,213 with a strong 84% sell order activity. Typical hold times range from 85 to 94 days across these assets, highlighting varied investor engagement.
