✔ Re-proven on a forked chain
We re-executed this exploit against the incident state on a forked chain; it moved value, and the patched control resisted. The signed, independently replayable receipt ships with the report.What this class of bug is
Oracle-manipulation attacks corrupt the price or data feed a contract trusts, so downstream logic executes on false inputs and mis-prices collateral or debt.
How to read this page. The dollar figure is the publicly reported loss attributed to this
incident. A ProveWall re-proof reproduces the vulnerability class/mechanism by execution on a forked chain,
with a signed receipt — we say so explicitly only once that execution has passed.

Want your own contract actually proven — not guessed?
Static tools and LLM auditors ask "is there a check here?" and miss the check that exists but is wrong. OmniGuard Labs runs the exploit on a forked chain and sends you a signed pass/fail receipt. Request a proof-backed audit →
