$482K Trading Bot Loss Tests Lighter's Risk Engine, No Liquidations Triggered

A malfunctioning trading bot on Lighter briefly overwhelmed its HYPE and ZEC markets, resulting in $482,000 in losses but triggering no liquidations. The bot executed $27 million in HYPE trades (74.2% of market volume) in five minutes, pushing the token from $56.31 to $60.96, while $220.8 million in ZEC trades (86.7% of activity) drove the price from $478 to $521. Both tokens returned to normal levels shortly after.

Lighter's risk engine successfully isolated the disruption by employing a fair price mechanism for margin calculations instead of relying on the last traded price, preventing healthy accounts from being liquidated due to temporary spikes. The bot's losses were largely redistributed to liquidity providers: the Lighter Liquidity Pool earned approximately $143,000, with 40 unaffiliated traders each generating over $1,000 by filling limit orders.
