Lighter Withstands Bot-Driven Market Disruption with Risk Engine

A trading bot malfunction on Lighter caused a $482K loss for the account, but thanks to its risk engine, the damage was limited.

The bot executed $27 million in HYPE trades within five minutes, representing 74.2% of total volume, and also traded $220.8 million in Zcash (ZEC), accounting for 86.7% of market activity.

The rapid price swings caused the value of Hyperliquid (HYPE) to rise from $56.31 per token to $60.96 on Lighter, while on other exchanges it remained near $58, and also pushed up the price of ZEC from $478.00 to $521.00.

The incident tested Lighter's risk engine more than its markets, but it successfully contained the disruption and prevented liquidations, isolating the damage instead of allowing broader market contagion.
