Briefing

500,000 USDC of exploit proceeds went through a laundering route this morning.

Every hop took a cut. This operator always takes exactly one percent.

Halfway down, the route split. A copycat crew took the other half.

Find where the operator's trail ends.

Objective

Identify the final wallet in the operator's 1% skim chain — the last wallet to receive a 1%-skimmed transfer.

Clues

4/4

01
The operator takes exactly 1% at every hop. Not 1.5%. Not 'about one'.
02
The operator's skims always land in the same wallet.
03
The trail ends at the first wallet that forwards without taking a cut.
04
At the split, the operator's half kept paying the same fee wallet as the source.
