Primary security firms like CertiK warn of potential billions more in losses without enhanced protection measures. Dr. Ronghui Gu, Co‑founder, CertiK, stated, "While the overall figures are alarming, it is important to point out that the majority of the funds lost in H1 were attributable to two concentrated, high‑impact events." Historical comparison indicates similar incidents, such as Ronin Bridge, however, 2025 marks unprecedented scale and focus on individual victims.
