What happened

  • 21 Oct 2026: analysts flagged about 15.99M USDT moving from a CoinDCX-linked wallet. The CEO first called it a possible false alarm. CoinDCX later confirmed it absorbed a 15.99M USDT loss.
  • Root cause per CoinDCX: users kept depositing to addresses compromised in the July 2025 incident. CoinDCX “sweeps” those addresses, and that sweep process failed for a period, so funds accumulated and were taken. ZachXBT disputed that the wallet was retired, saying it was still sweeping user deposits in April and May 2026.
  • Attribution: none stated.
  • Response: CoinDCX says all affected deposits were credited and the loss was absorbed from its own reserves. A USD 2.2M Tether freeze is reported by one outlet only.
