Small Pools Keep Bleeding From Arithmetic, Not Attackers

A steady stream of small drains caused by accounting and arithmetic logic errors in low-TVL pools and forked contracts — double-counted bonuses, reserve-accrual mismatches — keeps DeFi incident frequency high even as dollar losses stay concentrated in a few large exploits, so incident counts decouple from loss magnitude and unaudited forks of yield logic remain the recurring source.

Why the conviction moved

Oct 8
Strengthened +2
On the same day, a rounding flaw drained a legacy Set Protocol product. It adds another small arithmetic-logic incident that pushes up incident counts without adding much to dollar losses.
Oct 7
Strengthened +1
The latest roundup adds several small incidents (a legacy Set Protocol product, a Perpetual Protocol vault, BNB Chain token contracts including the roughly 1,546 BNB MOKE over-mint). Incident counts keep rising even though individual losses are small, which is the split between frequency and size this thesis describes.
