CoinDCX Hack 2025: $44 Million Cyberattack Shakes India’s Crypto Scene—What You Need to Know
On July 19, 2025, CoinDCX, one of India’s leading cryptocurrency exchanges, suffered a major cyberattack, resulting in the theft of approximately $44 million from an internal operational account. This incident, described as a “sophisticated server breach,” has sent ripples through the crypto community, raising concerns about security in the rapidly growing Indian crypto market. In this article, we’ll break down the details of the CoinDCX hack, its implications, and what it means for users and the broader crypto industry.

What Happened in the CoinDCX Hack?
On July 19, 2025, hackers targeted an internal operational account used by CoinDCX for liquidity provisioning with a partner exchange. The breach resulted in the loss of $44 million (approximately ₹380 crore), making it one of the largest crypto hacks in India since the WazirX breach in 2024, which saw $230–$235 million stolen. According to CoinDCX co-founder and CEO Sumit Gupta, the attack was a “sophisticated server breach,” but crucially, no customer funds were affected, as user assets are stored in segregated cold wallets.
Blockchain investigator ZachXBT traced the attacker’s movements, revealing that the hacker’s address was initially funded with 1 Ether (ETH) via Tornado Cash, a privacy protocol often used to obscure transaction origins. The stolen funds were later bridged from Solana to Ethereum, indicating a complex, multi-chain exploit.

CoinDCX’s Response to the Hack
CoinDCX acted swiftly to contain the breach:
- Isolated the Affected Account: The compromised liquidity account was immediately isolated to prevent further losses.
- No Customer Funds Impacted: The exchange emphasized that user wallets, stored in secure cold storage, remained unaffected. Regular trading and INR withdrawals continued without disruption.
- Treasury to Absorb Losses: CoinDCX committed to covering the $44 million loss from its own treasury reserves, ensuring no financial burden on customers.
- Investigation and Recovery Efforts: The company is collaborating with a partner exchange (identity undisclosed) and cybersecurity firms to trace and recover the stolen funds. A bug bounty program was announced to encourage ethical hackers to identify vulnerabilities.
- Web3 Mode Paused: As a precaution, CoinDCX temporarily paused its Web3 services (supporting DeFi tokens), which were restored by July 20, 2025.
Sumit Gupta, in a series of posts on X, emphasized transparency: “What defines a company isn’t just what happens, but how we respond… we will continue to handle this situation with full transparency.” However, some skepticism persists, as we’ll explore below.
Community Reaction and Transparency Concerns
The CoinDCX hack sparked significant discussion on X, reflecting a mix of relief, concern, and skepticism:
- Relief for Customer Safety: Users like @MasterCryptoHq praised CoinDCX for confirming that no customer funds were affected and for covering losses from their treasury.
- Transparency Criticism: Blockchain sleuth ZachXBT called out CoinDCX for a 17-hour delay in disclosing the breach, noting that the exchange only went public after his alert on X. This raised questions about proactive transparency.
- Server Overload: The sudden spike in user queries post-hack overwhelmed CoinDCX’s portfolio-related APIs, causing temporary issues with portfolio loading. Co-founder Neeraj Khandelwal confirmed additional server capacity was provisioned to resolve this.
For those affected by financial or legal disputes stemming from such incidents, Raghav Writes offers free legal drafts to help draft complaints or seek regulatory recourse in India.
How Does This Compare to the WazirX Hack?
The CoinDCX hack comes exactly one year after the WazirX breach on July 18, 2024, where $230–$235 million was stolen, linked to North Korean hackers. Key differences:
- Scale: WazirX’s loss was significantly larger, impacting user funds directly, while CoinDCX’s breach was limited to an internal account.
- Response: WazirX halted trading and withdrawals, causing panic, and proposed a controversial 55/45 loss-sharing model. CoinDCX maintained normal operations and absorbed the loss entirely.
- Recovery: WazirX recovered only $3 million of $230 million, while CoinDCX’s recovery efforts are ongoing but face challenges due to the use of Tornado Cash.
This comparison underscores CoinDCX’s stronger initial response but highlights the persistent cybersecurity risks in India’s crypto sector. For legal insights on protecting assets, visit Raghav Writes for free resources.
Broader Implications for the Crypto Industry
The CoinDCX hack is part of a troubling trend, with crypto losses reaching $2.5 billion in the first half of 2025 alone, per Chainalysis. Other recent hacks include Bybit ($1.5B, February 2025) and Nobitex ($100M, June 2025). This incident raises several concerns:
- Security Vulnerabilities: The use of Tornado Cash and cross-chain bridging suggests sophisticated attackers exploiting centralized exchange weaknesses.
- Regulatory Scrutiny: In India, where crypto is legal but heavily regulated, this hack could prompt stricter oversight. CoinDCX’s compliance with the Financial Intelligence Unit (FIU) India contrasts with earlier allegations (denied by Gupta) of using a non-FIU-registered entity.
- Investor Trust: The 17-hour disclosure delay and comparisons to WazirX may dent CoinDCX’s reputation, despite its robust response.

If you’re a CoinDCX user, here are actionable steps:
- Monitor Official Updates: Follow CoinDCX’s X account (@CoinDCX) and Sumit Gupta (@smtgpt) for real-time incident reports.

Why This Matters for India’s Crypto Future
Founded in 2018, CoinDCX is India’s first crypto unicorn, with over 16 million users and $492 million in monthly spot trade volume (May 2025). Its robust security measures, including ISO/IEC 27001:2022 certification and multi-signature cold wallets, made this breach surprising. The incident underscores the need for:
- Proactive Security: Exchanges Ascent bounty programs and regular audits can prevent future breaches.
- Transparency: Timely disclosures build trust, as delays fuel skepticism.
- Industry Collaboration: CoinDCX’s bug bounty program and partnerships signal a move toward collective cybersecurity efforts.
