CoinDCX Says Company Will Cover $15.99 Million Legacy Wallet Loss

CoinDCX will absorb a $15.99 million loss after an investigation tied an Oct. 21 security incident to deposits left in a decommissioned wallet system, the Indian crypto exchange said.

CoinDCX said the affected wallet infrastructure had been retired after a security incident on July 19, 2025, but an unknown vulnerability remained. An automated service that normally moved funds from old addresses stopped working for a period, allowing deposits sent to those addresses to accumulate.

The exchange put the resulting loss at 15.99 million USDT and said it would absorb the cost. Users were still able to send funds to the retired addresses while the automated service was unavailable.

CoinDCX said its current trading and wallet systems were not affected. Customer funds are held in segregated cold wallets, and deposits, withdrawals and trading have operated normally over the 72 hours before the update. The company said it plans to strengthen monitoring of its legacy systems in response to the incident.
