Mound Inc. — The Company Behind the Hack
Mound Inc. (마운드) is the South Korean technology company that built and operated both PancakeBunny ($45M hack, May 2021) and Qubit Finance ($80M hack, January 2022). The company received $1.6M in seed funding from Binance Labs in April 2021 — nine months before the $80M exploit that Binance has never been held accountable for.
