Whitehat satya0x reported a critical vulnerability in @wormholecrypto on Feb 24 via Immunefi.
The bug was quickly patched, no user funds were affected, and satya0x received a $10 million payout from Wormhole, the largest bounty payout on record.

It is a small coup that fairness is so associated with "fair ordering" / time based ordering
There is no single notion of "fair." These protocols privilege a different set of actors and MEV extraction is a different "game" to play on them

In reality SPOs have always full control over transaction ordering, not exposing the API of the tx management is just wishful thinking, in reality you can always patch the node, hook up debugger to it or find some other way, to order, prioritize, or exclude transactions in block.
