SlowMist's Yu Xian: The root cause of over $100 million being stolen from Balancer is that, in the implementation of Balancer v2's Composable Stable Pool, scaling factor calculation errors can be amplified and exploited through low-liquidity swaps.
Golden Finance reports that SlowMist's Yu Xian released an analysis stating that the reason behind over $100 million being hacked from Balancer is due to a precision loss issue in its v2 composable stable pool implementation. The problem stems from the use of scaled integer fixed-point calculations, which allow attackers to amplify price discrepancies through small, low-liquidity exchanges and secure significant profits.
