In one of India’s most high-profile crypto breaches, CoinDCX has confirmed a theft of approximately ₹368 crore ($44 million) — not from user wallets, but from its internal operational account. The July 19 hack has since exposed critical gaps in backend crypto infrastructure, real-time breach response, and transparency within Indian exchanges.
WireUnwired investigates what went wrong, how the breach was executed, and why this is a red flag for the broader Indian crypto ecosystem.

The CoinDCX Hack: What Was Compromised
According to CoinDCX, attackers exploited a server-side vulnerability to gain access to a liquidity provisioning account connected to a partner exchange. This account, while not holding customer assets, had access to treasury funds used for market operations.
Key facts:
- Entry point: Server-side breach of internal ops account
- Amount lost: ₹368 crore ($44 million)
- User funds affected: None
- Public disclosure: 17 hours after the breach was flagged by independent analyst ZachXBT
The compromised account was not cold-stored, not audited publicly, and lacked the hardened protections typically applied to customer wallets — a critical architectural oversight.
How the CoinDCX Hack Was Executed
This breach followed a pattern increasingly common in global crypto thefts: a combination of hot wallet access, cross-chain laundering, and mixers that obscure the fund trail.
Step-by-step breakdown:
Initial anonymization: Attacker wallet funded via Tornado Cash (1 ETH), a crypto mixing tool that hides identity.
Exploit launch: Server-side breach provided access to CoinDCX’s internal liquidity account.
Fund movement: Stolen assets were bridged from Solana to Ethereum to complicate traceability.
Laundering: Assets further obfuscated via Tornado Cash and privacy protocols.
Public detection: Blockchain investigator ZachXBT flagged suspicious outflows before the exchange acknowledged the breach.
CoinDCX later confirmed that no customer wallets were compromised and pledged full absorption of losses from company reserves.
Blockchain Forensics: Why Recovery Will Be Difficult
The laundering path followed a highly effective pattern designed to resist both real-time analytics and legal intervention.
| Phase | Technique Used |
|---|---|
| Anonymization | Tornado Cash used to fund attacker wallet |
| Cross-chain bridging | Movement from Solana to Ethereum |
| Mixer utilization | Multiple transfers through privacy-preserving protocols |
| Trace obfuscation | High-volume fragmentation into multiple wallets |
CoinDCX has since partnered with cybersecurity experts, exchange partners, and blockchain analytics firms to trace any accessible assets. However, full recovery is unlikely, a fact acknowledged by most security professionals familiar with such laundering paths.
Response Timeline and Industry Criticism
One of the most widely criticized aspects of the incident was the 17-hour delay in public disclosure.
While CoinDCX maintains that user funds were safe and all trading operations remained active, the delay raised serious questions about:
- Lack of real-time incident response protocols
- Absence of transparency standards
- No structured user notification framework
This breach was not just a test of security systems — it was a test of operational maturity, and the exchange’s handling of the crisis showed that India’s crypto industry may not be ready for coordinated, high-velocity attacks.
Lessons for Indian Crypto Exchanges
WireUnwired’s review of the breach indicates that multiple structural weaknesses contributed to the outcome. If not addressed across the ecosystem, these risks could multiply under future attacks.
| Structural Weakness | Risk Introduced | Recommendation |
|---|---|---|
| Non-audited treasury systems | Single point of failure | External audit and real-time monitoring |
| Server-side exposure | Remote breach potential | Hardened perimeters and isolation |
| Lack of live detection | Delayed mitigation and public alert | On-chain analytics integration |
| Poor communication planning | User panic and reputational damage | Breach response playbooks and dashboards |
Broader Implications: Not an Isolated Case
This is the second major Indian crypto exchange hack in a year, following the WazirX ₹1,900 crore theft in 2024. Globally, Chainalysis estimates over $2 billion in stolen assets just in the first half of 2025 — underscoring the growing sophistication of crypto crime.
Despite these high-profile events, India lacks unified crypto security regulations. Each exchange operates under its own internal governance, and most do not publicly disclose their operational security frameworks.
WireUnwired’s Take: A Ticking Clock for Reform
CoinDCX survived the breach with customer trust intact — but only because funds lost were internal. The next exchange may not be so lucky.
If Indian platforms continue to under-prioritize backend infrastructure security, avoid mandatory audits, and lack coordinated disclosure norms, the crypto sector risks losing both user confidence and regulatory goodwill.
India’s Web3 future needs:
- Mandatory disclosure standards
- Security audits of all operational wallets
- Clear timelines for breach notifications
- Greater transparency in cross-chain liquidity operations
The CoinDCX breach should be treated not as an isolated failure, but as a warning — one that the Indian crypto ecosystem can’t afford to ignore.
