In the first half of 2026, crypto hacks H1 2026 reached a record high: Blockaid’s report published 28 July 2026 counted 212 verified exploits draining over $1.1 billion in digital assets, making this six-month window the most damaging exploit period the firm has ever tracked, with incident volume running 3.4 times Blockaid’s entire 2025 tally.

Key Takeaways: What the Blockaid H1 2026 Report Found
- 212 verified exploits recorded in H1 2026 per Blockaid, published 28 July 2026.
- Total losses exceeded $1.1 billion (roughly Rs 9,200 crore at current rates).
- The incident count is 3.4x Blockaid’s entire 2025 tally, making this the busiest exploit period ever tracked by the firm.
- KelpDAO and Drift Protocol were the two largest individual victims, losing approximately $292M and $285M respectively.
- Ethereum and Solana bore the heaviest chain-level losses at $332M and $326M.
- Neither of the two biggest hacks exploited audited smart-contract bugs; attack vectors were access-control failures and key-management weaknesses.
- Other trackers give different totals: CertiK logged $1.32B across 344 incidents; TRM Labs counted $972M across 207 incidents.
How Bad Were Crypto Hacks H1 2026 Compared to Previous Years?
Blockaid’s $1.1 billion figure sounds enormous until you look at H1 2025, when losses hit roughly $2.3 billion, heavily inflated by the $1.5 billion Bybit theft in February 2025. Strip that single incident out and crypto hacks H1 2026 are actually worse on a per-incident basis, with 212 attacks versus a far smaller incident count in the same period last year.
The 3.4x surge in incident volume is the real alarm bell. More protocols are being hit, more frequently, and attackers are clearly not slowing down despite improved tooling across the industry.
Why Do Different Trackers Give Different Numbers?
CertiK’s Hack3d report for H1 2026 puts losses at $1.32 billion across 344 incidents. TRM Labs logged $972 million across 207 incidents. Blockaid sits in the middle at $1.1 billion and 212 incidents.
The gaps exist because each firm applies its own methodology. Some count attempted exploits that were partially recovered; others exclude phishing and social engineering; a few include NFT-related fraud that others classify separately. None of these figures are wrong; they are just measuring slightly different things. For Indian investors tracking exposure on platforms like WazirX, CoinDCX, ZebPay or Mudrex, the practical takeaway is the same: the threat landscape got significantly worse in 2026.
H1 2026 vs. Prior Periods: At a Glance
| Period | Source | Incidents | Total Losses |
|---|---|---|---|
| H1 2025 | Multiple trackers | Not separately published | ~$2.3B (incl. $1.5B Bybit) |
| H1 2026 | Blockaid | 212 | $1.1B+ |
| H1 2026 | CertiK | 344 | $1.32B |
| H1 2026 | TRM Labs | 207 | $972M |

The Biggest Crypto Hacks of 2026: KelpDAO, Drift Protocol, and More
What Was the Biggest Crypto Hack of 2026?
KelpDAO holds that unwanted title with losses of approximately $292 million. Drift Protocol follows closely at around $285 million. Together, those two incidents account for more than half of Blockaid’s total H1 2026 figure, illustrating how a handful of large events can dominate the overall statistics.
What is striking about both cases is that neither hack exploited a bug in an audited smart contract. Security audits are necessary but clearly not sufficient. The attack vectors in these cases pointed to access-control failures, key-management weaknesses, or front-end compromises rather than on-chain code errors.
This pattern is consistent with what we have seen in bridge exploits like the AFX incident, where the vulnerability sat in the infrastructure layer, not the contract layer. Bridges and cross-chain protocols remain a favourite target; you can read more about how these attacks work on our Web3 explainer page.
Which Blockchain Lost the Most to Hackers in H1 2026?
Ethereum topped chain-level losses at $332 million, per Blockaid’s breakdown. Solana was close behind at $326 million. These two chains dominate DeFi activity, so it is unsurprising they attract the most attention from attackers.
The $332M loss on Ethereum is a reminder that being the most battle-tested smart-contract platform does not make you immune. Volume creates opportunity, and Ethereum’s total value locked means the rewards for a successful exploit are enormous. Solana’s rapid growth in DeFi and meme-coin activity has similarly expanded its attack surface.

Main Attack Vectors Driving Crypto Hacks H1 2026
Blockaid’s report highlights that access-control failures and key compromises drove a disproportionate share of losses. Phishing and social engineering attacks contributed to incident volume but tended to produce smaller individual losses. Flash-loan exploits, once the dominant vector, appear to have declined as a share of total losses even if absolute numbers remain significant.
What Crypto Hacks H1 2026 Mean for Indian Investors
India’s crypto community is growing fast. SEBI’s evolving framework and RBI’s cautious stance have not stopped millions of retail investors from using platforms like CoinDCX, WazirX, ZebPay and Mudrex to buy and hold digital assets. Most Indian retail investors keep funds on centralised exchanges rather than DeFi protocols, which offers some protection from the exploit types dominating this report.
That said, the 30% flat tax on VDA gains and 1% TDS on transactions already make crypto investing expensive in India. Losing funds to a hack on top of that tax burden would be devastating. Indian investors exploring DeFi protocols or Bitcoin-adjacent yield products should treat security due diligence as non-negotiable before committing funds.
Practical steps: check whether any protocol you are using has a recent, public security audit; never store large amounts in hot wallets; and treat any unsolicited message offering yield opportunities as a scam until proven otherwise.
Industry Response and What to Watch Next
Security firms including Blockaid are expanding real-time transaction screening tools that flag malicious contracts before a user signs a transaction. Several major wallets have integrated these checks. The technology is improving, but so are attacker tactics, and the H1 2026 data makes it clear that the offense is currently outpacing the defense.
Regulators globally are watching. Any major hack involving a platform with Indian users could draw scrutiny from SEBI or the Financial Intelligence Unit. The second half of 2026 will be telling: if incident counts stay elevated, expect louder calls for mandatory security standards across DeFi protocols.

Frequently Asked Questions
How much crypto was stolen in crypto hacks H1 2026?
According to Blockaid’s report published 28 July 2026, over $1.1 billion was stolen across 212 verified exploits in H1 2026. CertiK puts the figure higher at $1.32 billion across 344 incidents, while TRM Labs counts $972 million. Differences arise from varying methodologies on what counts as a verified exploit.
What was the biggest crypto hack of 2026?
KelpDAO suffered the largest single exploit in H1 2026, with losses of approximately $292 million. Drift Protocol was a close second at roughly $285 million. Neither hack was caused by a bug in an audited smart contract; both pointed to infrastructure or access-control weaknesses rather than on-chain code vulnerabilities.
Which blockchain lost the most crypto to hackers in H1 2026?
Ethereum led chain-level losses at $332 million, followed by Solana at $326 million, per Blockaid’s breakdown. Both chains host the majority of DeFi activity, making them the most attractive targets. High total value locked means even a small percentage exploit can produce a large absolute dollar loss.
What were the main attack vectors in crypto hacks H1 2026?
Blockaid’s H1 2026 report identifies access-control failures and private key compromises as the dominant vectors by dollar value. Phishing and social engineering drove incident volume but produced smaller per-event losses. Flash-loan exploits declined as a share of total losses compared to prior periods, though they remain a live threat.
Why do different crypto security firms report different hack totals for H1 2026?
Each firm uses its own methodology. Some include phishing and social engineering; others count only on-chain smart-contract exploits. Recovery of stolen funds may or may not be subtracted from totals. Incident thresholds also differ: a $50,000 exploit might appear in one firm’s count but not another’s. Always check which methodology a report uses before comparing figures across sources.
