Our Q2 2026 Security & Compliance Report has been released ⬇️
$763.9M was stolen across 67 incidents, the worst since Q2 2025. 88% of the losses came down to operations.
Smart contracts were still the most common failure point, 44/67 incidents, but they accounted for just 11% of the funds lost.
All of this happens as MiCA comes into force, where only about 20% of registered firms secured authorization, roughly 210 of the more than 1,200 that once declared intent.
This quarter's report is built around one idea, the Architecture of Trust: how security, compliance, and risk intelligence together influence which teams institutions are willing to work with.
Inside, we cover:
▫️MiCA/DORA and the GENIUS Act
▫️Stablecoin regulations
▫️AI regulation across the EU and US
▫️How allocators run due diligence
▫️What comes next in Q3 2026
As digital assets become more exposed to public markets, institutional capital increasingly follows issuers that can consistently demonstrate they remain safe and sound.
Built with input from @chainlink, @moodysratings, @Bybit_Official, @SuiNetwork, @StellarOrg, @1MoneyNetwork, Abraxas Capital, @AlliumLabs, @svrn_ai, @EisnerAmper, DA Insured, @howdenlocaluk – alongside Hacken.

AI is becoming a part of how teams evaluate software security. @VitalikButerin raises a useful question: what does it mean for a program to be “secure”?
“AI-assisted verification could shift the advantage toward defenders”. Teams first need to define what a program must guarantee, then check whether the implementation satisfies those properties.
One of his points is that security definitions are additive. Different teams can specify different properties and check whether the software satisfies both. If those properties conflict, the team just found a design decision it needs to resolve.
From an assessment perspective, every assurance claim should make 5 things clear:
• Whether program/system requirements are well defined.
• Which property was checked?
• Under what assumptions?
• Across which system boundary?
• What evidence supports the result?
That shows the team what the result supports and where further review is needed. For Canton builders, this applies to who may exercise a Daml choice and how related contracts change state.
As part of Hacken’s ongoing R&D into AI-assisted security reviews, our AI auditor for Daml examines party authority and related contract state across workflows.
This surfaces initial findings for deeper manual review and provides auditors with specific questions to investigate.

Stablecoins and tokenized gold were converted to ETH within approximately 25 minutes through UniswapX and Uniswap liquidity pools.
On Optimism, ETH was converted to USDC, transferred to Ethereum via Circle CCTP, and sold in some cases within 24 seconds of minting. The operator accepted approximately 3% slippage in exchange for speed.
Approximately 53,000 ETH is currently held across six newly created Ethereum addresses. No transfers to mixers, bridges or centralized exchanges have been observed to date.

Update on Bitget Hot Wallet Incident
Gracy Chen, CEO of Bitget, confirmed that the estimated amount of affected funds is approximately $351.6 million. Cold wallets remain fully secure, and user funds are fully safe.
The Bitget team took action:
• An emergency response within minutes of detection
• Addresses identified, flagged, and reported
• Withdrawals temporarily suspended
• Law enforcement and on-chain security firms notified.
Official coverage:
nitter.net/GracyBitget/status/210…
nitter.net/bitget/status/21032365…
At 18:31 UTC on September 24, 2026, Bitget’s security systems identified unauthorized transfers involving a limited number of hot wallets.
Our security team immediately activated emergency response procedures and began a full investigation.
Based on our current assessment, approximately $351.6 million in assets were affected. Bitget’s cold wallets and the overwhelming majority of platform assets remain secure and unaffected.
Most importantly, user funds remain protected.
The incident falls within the coverage of Bitget’s User Protection Fund, which currently holds more than $464 million.
Customer account balances remain accurate, and deposits and trading continue to operate normally.
As a precaution, withdrawals have been temporarily suspended while our teams complete a comprehensive security review.
We have identified and flagged the relevant transfer addresses and have formally engaged law enforcement agencies and leading on-chain security partners.
We are working around the clock to restore withdrawal services as soon as it is safe to do so.
Bitget will provide further updates through our official channels.
We will not speculate on the attack vector while the investigation remains ongoing. Our focus is on protecting users, securing all systems, and delivering complete transparency throughout this process.

How did @osldotcom build DORA competency ahead of entering the EU market?
With an existing ISO 27001 foundation, the training had to go beyond introductory material and engage the operational realities of a licensed, publicly listed group.

This reel captures an evening where physical art sat beside the art of digital assets.
Thank you @thevault_soft for co-hosting "Art and Digital Assets" with us at @EBlockchainCon in Barcelona and sharing this look back⬇️
Last week in Barcelona, we co-hosted “Art and Digital Assets” with @hackenclub during European Blockchain Convention.
It was an evening where art met conversations around digital ownership, security, provenance and the future of on-chain assets.
Thank you to everyone who joined us and to Hacken for co-hosting the evening with us.

You have seen traditional security audits. Now watch an AI Auditor face the same objective.
On September 29, Hacken and @NODERS_TEAM are running our AI Auditor on a real Daml smart contract
The session is part of HackCanton Season 3 by @appsfactory_cc — 450 builders from 48 countries currently building on @CantonNetwork.
For founders and engineers on Canton, this live workshop is a chance to inspect the workflow and see how the system surfaces Daml-specific risks: what it flags, what evidence supports each finding, and what your team can actually fix.
Leave with a clearer view of what your current process covers, where AI-assisted review can add value, and whether your Daml codebase should be audited next.

“Maintaining VARA compliance can be harder than achieving it for the first time”
Dmytro Yasmanovych, Hacken: "Every recurring control needs an owner. A quarterly scanning policy needs 4 reports, one for each quarter."
Dmytro and leaders from Chainberg, @rivcapitalgroup, and @Gate answered implementation questions at different stages of the VARA licensing process.
Edwin Cheung, @Gate: “VARA never asked for one single document.”
The evidence included procedures, system configurations, logs, committee records, audit reports and live demonstrations using real data.
Kashif Abbas, Chainberg: “Even after the penetration-testing scope was agreed, VARA challenged it again.”
Applicants need to defend assessor independence and prove that the scope covers the relevant architecture. The report must also record findings and remediation.
Guido Rocco, @rivcapitalgroup: “Digital-asset experience is not the norm in the security sector.”
The assessor needs to understand the product, custody paths, signing flows, and infrastructure under review.
Use the full panel to identify the next control and evidence in your VARA licensing process.
