What this measures, and what it does not Incidents, classes, techniques and amounts are DefiLlama's record. Its dashboard and documentation give no method note: they do not say how incidents enter the record, which date's prices an amount uses, or whether amounts are before or after any recovery. If the record depends on public reporting, it will be most complete for the largest events on the most watched chains, so a chain's count may reflect where value and attention concentrate as much as where code is weakest. Chain figures overlap: a multi-chain incident counts in full on every chain it touched. Absence from this record is not evidence of safety.
