Ghost fills are back ! exploiters found a new way to cancel their orders after they got filled. They are printing over 6 figs/day across a range of new wallets. It's yet unknown how the exploit work but the signs are there : - total absence of adverse fill - impossible rewards/fills ratio - multiple reports traders having their ordered cancelled post fills - multiple new accounts printing $5k every day then being cycled through Right now it's affecting mostly weather markets, because that's where adverse fills are most prominent, but the exploit is probably general Ghost fills had been fixed by the deposit wallet update a few months ago, but it seems attackers found a new way @mustafap0ly @williamlegate look this up

This is due to a bad state not staying in sync with the chain all the time, causing a trade not to be taken down when it would revert. The percentage of affected trades is small, but it's more prominent in markets with lower liquidity, like weather. We are working on a fix for this now. This fix will also fix the reward issue, as it’s related to it.

@Autonomous_Chad honestly weird how this can even happen. polymarket should fix with ultra high priority, makes the platform unsusable

@Autonomous_Chad *this time they are cancelling the orders before it’s filled it’s arguably worse than the previous exploit x.com/prathwik0/stat…

@Autonomous_Chad It never left tbh

@Autonomous_Chad And me lping .. Everyday get bad filled

@Autonomous_Chad The same is happening on e-sports too

@Autonomous_Chad Which chain is this happening on or everywhere at once?

@Autonomous_Chad Polymarket is vibe coded. This is all I have to say.

@Autonomous_Chad Interesting find 👀

@Autonomous_Chad No, Taker delay 250ms

@Autonomous_Chad Market structure is only as strong as its execution guarantees. Reliability compounds trust.

@Autonomous_Chad That's why fully onchain prediction markets matters !

@Autonomous_Chad i noticed some weird cancellations too
