What Happened?
The Securities and Futures Commission (SFC) of Hong Kong has released a tough new set of custody rules for virtual asset trading platforms. These guidelines come after a wave of global crypto hacks led to billions in losses and revealed serious weaknesses in existing security systems. The move is part of a broader regulatory push to bolster investor protection and reinforce Hong Kong’s role as a major player in the crypto space.

SFC Responds to Global Crypto Hacks With Custody Overhaul
Hong Kong’s regulatory shift comes in direct response to a sharp rise in crypto security breaches around the world. In the first half of 2025 alone, hackers stole $2.47 billion across 344 incidents, with wallet-related breaches accounting for $1.7 billion from just 34 attacks.
Some of the most devastating cases include:
- A $1.5 billion loss at Bybit in February
- A recent $48 million hot wallet breach at Turkish exchange BtcTurk
- Increasingly fast attacks, with some funds stolen in just four seconds, far outpacing exchange detection systems
Over 70 percent of stolen funds have been linked to North Korean hackers, especially the Lazarus Group. Recovery efforts have returned only $187 million, highlighting the urgency for regulatory action.
New Crypto Custody Standards Unveiled
The SFC’s newly issued circular lays out mandatory controls that all licensed platforms must implement immediately. These include:
- Certified hardware security modules
- Cold wallets with no smart contract functionality
- Air-gapped and physically secure environments for private key operations
- 24/7 security operations centers for monitoring networks, wallets, and infrastructure
- Whitelisted withdrawal addresses only
- Multi-factor physical access controls
- Systematic transaction verification
- Third-party independent assessments
- Staff training to prevent blind signing
The ban on smart contracts in cold wallets is a significant shift, as these contracts are widely used by institutional custodians. The SFC cited concerns over increased attack surfaces and protocol-level vulnerabilities introduced by on-chain contracts.
“ASPIRe” Roadmap and Stablecoin Licensing Drive Hong Kong Forward
These custody rules are part of the SFC’s broader ASPIRe initiative, which includes a 12-step plan launched in early 2025 aimed at improving digital asset security, attracting institutional investors, and aligning traditional finance with blockchain infrastructure.
Key developments under this framework include:
- Launch of spot Bitcoin and Ether ETFs in April 2024
- New licensing regime for over-the-counter trading and custody services
- Legislative passage of the Stablecoins Bill in May 2025
- Licensing of 11 virtual asset platforms, with 9 more under review
- Over 40 stablecoin license inquiries since the regulation took effect on August 1
Companies such as Circle, JD.com, Ant Group, and Standard Chartered have all expressed intent to enter the Hong Kong market under the new rules.
Industry Response and Outlook
Industry voices have praised the move for raising the bar on security, though some express concern over its impact on smaller players. Chen Wu, CEO of licensed exchange Ex.io, called the circular “a critical step in raising custody standards,” while noting the risk of market consolidation.
Security expert Berndard Mueller supported the regulator’s skepticism of smart contracts in custody, citing complex governance risks and expanded attack surfaces. He urged for outcome-based standards that balance security with flexibility.
CoinLaw’s Takeaway
I think this is the kind of move we desperately need in crypto. With billions lost and most recovery efforts falling flat, it’s clear that the old “trust the platform” model is broken. Hong Kong’s detailed, no-nonsense custody rules show that real security comes from structure, not just promises. Banning smart contracts in cold wallets may ruffle feathers, but it forces custodians to rethink their attack surfaces. I like seeing a regulator take security seriously, and these standards could push the whole industry in a safer direction.
