Attack Timeline- 23:47 UTC — First suspicious call via front-running
- 23:49 — Series of failed transactions (gas war?)

Their cookie-cutter postmortem will likely credit some "external researcher" for "helping improve security."Maybe someday bridges will implement basic replay protectionReviewing logs now—the exploit leveraged a long-known IBC packet handling vulnerability. But who reads whitepapers before deployment?
