Details
According to the post, CoinDCX’s reported hot wallet and several deposit addresses sent funds to a single TRON address late on October 21 (UTC+8). The outflow totaled roughly 15.99 million USDT and 5,783.81 TRON (TRX).
The largest single transfer moved about 15.82 million USDT. The receiving address then split the money across multiple wallets.
After several rounds of splitting, the funds reached deposit addresses on Binance, OKX, Gate, and other exchanges, Darcy said.
However, CoinDCX’s leadership disputed that any of those wallets still belonged to the exchange.

Gupta replied to Darcy’s post less than three hours after it went live.
“Thanks for highlighting but this is incorrect and CoinDCX wallets are not breached. Pls don’t spread rumours,” he said.
He explained that Arkham had tagged the addresses to CoinDCX. However, the exchange generated them in January 2025, and they were compromised during the July 2025 attack.
None of them had sent funds to the flagged addresses, he said. Gupta also noted that all CoinDCX addresses are public on its proof-of-reserves (PoR) page.
