ValueDeFi Incident: Incorrect Weighted Constant Product Invariant CalculationSummary
This incident was due to the mis-calculation by the protocol on the adopted weighted constant product invariant for non 50–50 ratio pools. There is no flashloan or price manipulation involved. The consequence of mis-calculated invariant allows for draining of affected pool funds. Currently, the bug has been exploited to attack 9 non 50–50 ratio pools with the estimated loss of $11M.
