ChainCatcher report: CoinDCX has issued further clarification regarding on-chain activity related to the TQKJQ wallet, stating that after the security incident in July 2025, the affected wallet addresses were deactivated. However, some users continue to deposit funds into the old addresses. The platform’s routine fund aggregation process was temporarily inactive, and this issue was identified this morning, resulting in certain operational losses, which CoinDCX will bear.
CoinDCX stated that, despite some users depositing funds to deactivated addresses, the affected user accounts have been credited accordingly. The platform confirmed that customer assets remain securely stored in independent cold wallets, and current active wallets and user addresses remain unaffected, with platform trading operations continuing normally. CoinDCX also reminded users to verify the latest deposit addresses exclusively through the official app or website to avoid transferring funds to deactivated addresses.
Previously, on-chain detective ZachXBT questioned why the deposit address TQKJQ continued to be used for approximately 10 months after the security incident, with about $15.8 million in user deposits unaccounted for.
