In a startling development, India's top crypto exchange CoinDCX suffered a $44 million breach, following a “sophisticated server attack” on one of its internal wallets used for liquidity provisioning . CEO Sumit Gupta confirmed the incident, assuring users that customer assets remain secure in cold storage .
🔍 What Exactly Happened?
When: Attack occurred ~17 hours before being disclosed on July 19, 2025 .
How: Hackers breached a “hot wallet” tied to liquidity on a partner exchange, transferring assets via Tornado Cash and cross-chain bridges .
User Impact: Trading and INR withdrawals remain unaffected. CoinDCX emphasized that customer funds are untouched.
📊 Key Highlights
Amount stolen: $44–44.2 million worth of crypto.
Wallet type: Internal operational/hot wallet.

⚠️ Pros & Cons (Point-by-Point)

Large-scale loss of operational funds (risk not fully mitigated).
Temporary service disruptions in Web3 trading could frustrate users.

Consider using hardware wallets for significant holdings.
Apply self-custody and diversify exchange usage when possible.

Potential ripple effects on investor confidence and market perception.
