> The exchange tied the failure to wallet infrastructure involved in a 2025 security incident and said customer balances and active trading were unaffected.

CoinDCX linked a 15.99 million Tether (USDT) loss to a breakdown in its automated deposit-sweep system that left old wallets holding funds, while saying it absorbed the loss and customer balances were unaffected.

The India-based exchange outlined the failure in an Oct. 25 update. CoinDCX said it detected unusual activity Oct. 21 and irregular fund movements the next day.

CoinDCX said deposits reaching deprecated addresses were credited to users, then moved to primary wallets by a separate service. Funds accumulated in older infrastructure when that service failed. The company did not specify how long the service was down.

CoinDCX tied the older infrastructure to a July 2025 security incident. It said customer balances, active trading and current wallet systems were unaffected.

The July 2025 incident involved about $44 million in exposure tied to an internal operational account. The update adds an explanation and a loss figure to the Oct. 21 outflows.
