Cobo: In-Depth Insights Into Custody Requirements And Tailored Solutions For Hong Kong Virtual Asset Exchanges And Fund Managers

By Eugene Wong (Head of Risk Management and Compliance of Cobo)

Hong Kong has made remarkable strides in establishing a legal and regulatory framework for virtual asset operations over the past year. In October 2022, the Hong Kong Government issued a policy statement setting out its support for virtual assets and commitment to fostering sustainable development of the industry in all aspects. On June 1st this year, the licensing regime for Virtual Asset Trading Platform (VATP) issued by the Hong Kong Securities and Futures Commission (SFC) came into effect, mandating VATPs to obtain a license to continue their operations in Hong Kong. Existing VATPs seeking a license must submit their applications to the SFC within 9 months, by February 29th, 2024. Failure to do so will require them to cease operation in Hong Kong by May 31st, 2024.

As of today, several virtual asset exchanges have publicly expressed their intention to apply for the VATP license in Hong Kong. According to market sources, there are currently more than a hundred institutions, with a significant number of them from the traditional financial sector, who have shown interest in the license. However, institutions from the traditional financial sector face a key challenge: a lack of experience in dealing with virtual assets, particularly in areas such as blockchain security, crypto custody, and technology infrastructure. It is crucial for these institutions to ensure they have adequate support during the planning and development stages, and seek expert opinions when needed, to comprehensively understand and mitigate potential security vulnerabilities that could pose significant risks, including irreversible asset losses.

To address this challenge, we have conducted an in-depth analysis of the custody requirements outlined by the SFC for VATPs and Type 9 licensed Virtual Asset Fund Managers (VA Fund Managers). Our aim is to assist institutions interested in applying for the VATP or VA fund management licenses in Hong Kong in better understanding the SFC's requirements and how Cobo can help with the license application.

Custody Requirements for VATPs

The SFC has issued comprehensive guidelines setting out the licensing requirements for virtual asset exchanges. The key points pertaining to custody requirements are as follows:

  • Custody of client assets must be provided by a wholly-owned subsidiary of the VATP

The SFC mandates that VATPs hold client virtual assets through a wholly-owned subsidiary that has a Trust or Company Service Provider License (TCSP) in Hong Kong. The use of third-party custodians is prohibited, as the SFC must maintain a direct regulatory handle of the custody entity within Hong Kong. Utilising a non-Hong Kong custodian would hinder the SFC’s ability to directly supervise the custodian, and in turn, compromise the security of client assets held by them.

  • Openness to new custody technologies

The SFC maintains an open-minded approach towards the custody technologies adopted by licensees. In the consultation conclusion document, the SFC states that they are closely monitoring new custody technologies, including MPC and key sharding. The primary requirement is that private keys and backups must be stored in devices with appropriate certifications, such as a certified HSM.

  • Asset allocation and safeguards for cold and hot wallets

The SFC sets out specific requirements regarding custody arrangements for exchange assets. In particular, it stipulates that 98% of user assets must be stored in cold wallets, while the remaining 2% can be stored in hot wallets and/or other storage options. Additionally, the SFC requires VATPs to put in place a compensation arrangement covering at least 50% of the assets in cold wallets and 100% of the assets in hot wallets and other storage options. The compensation arrangement may include third-party insurance, funds set aside on trust, and bank guarantees.

  • Implementation of a whitelisting mechanism on customer deposits and withdrawals

To mitigate the risk of money laundering, the SFC recommends VATPs implement a mechanism to whitelist addresses that users can transact with. This ensures the VATP clients only interact with their own wallets and/or approved third parties. Message signing and micropayment tests are cited by the SFC as examples of ways to verify whether a wallet address is indeed owned by the client.

  • Private keys must be stored in Hong Kong

To ensure effective supervision and enforcement, the SFC requires private keys to be stored locally in Hong Kong.

Custody Requirements for Virtual Asset Fund Managers (SFC Type 9 License)

For VA Fund Managers, the SFC sets out the custody requirements in the "Proforma Terms and Conditions for Licensed Corporations which Manage Portfolios that Invest in Virtual Assets" released in October 2019.

VA Fund Managers are responsible for selecting and appointing custodians for client assets. While self-custody is allowed in principle, VA Fund Managers must provide strong justifications to the SFC and demonstrate the associated risks can be effectively managed. In practice, it is more common for VA Fund Managers to appoint third-party custodians.

In addition, fund assets must be segregated from the VA Fund Managers' own assets. If a third-party custodian is appointed, fund assets should be segregated from the assets of other clients of the custodian.

The SFC also requires VA Fund Managers to consider appointing more than one custodian to mitigate concentration risk. This provides flexibility in terms of custody technology, platforms, and security approaches, promoting risk diversification.

When selecting custody solutions and custodians, the SFC provides a list of consideration factors for VA Fund Managers. The factors include:

  • Experience, track record, corporate governance structure, and background of senior management of the custodian;
  • The regulatory status of the custodian;
  • Whether asset segregation is in place;
  • Financial resources and insurance coverage of the custodian;
  • Operational capabilities of the custodian, including a wallet and private key management processes and security risk management measures;
  • Hardware and software infrastructure of the custodian;
  • Types of assets supported
