South Korea’s National Tax Service (NTS) is undergoing a significant revision of its digital asset management policies following a major security incident earlier this year. A leaked mnemonic recovery phrase resulted in the unauthorized transfer of $4.8 million in cryptocurrencies, sparking a debate over current security measures and pushing the agency toward reform.
What Drives the Revised Custody Strategy?
In an effort to enhance security, the NTS has decided to adopt third-party digital asset custodians, stepping away from its current internal management method. The agency, which functions under the Ministry of Economy and Finance, is responsible for tax collection and policy enforcement across the nation. Utilizing external custodians is part of a larger strategy to incorporate international best practices.
A new oversight team has been established by the NTS to oversee the evaluation and management of these custodians. They will be responsible for applying consistent procedures for the storage, audit, and removal of seized assets. This shift aims for completion by 2026, focusing on custodians with strong insurance, cybersecurity, and operational records.
How Will Custodians Be Evaluated?
The process for selecting custodians involves a thorough assessment emphasizing advanced security measures, multi-tier authorization, and secure digital storage. Potential partners must adhere to the Virtual Asset User Protection Act, meeting requirements for insurance, compliance, and reserves.
Evaluation criteria also cover the financial health and experience of custodian companies, especially in handling government crypto portfolios. The oversight team is tasked with guiding the transition and preparing employee training to ensure smooth protocol implementation across various departments.
A series of legal reforms accompanies these changes, addressing past digital asset security incidents, including one involving 22 Bitcoin. Repeat cases led governmental bodies to scrutinize and revamp their asset management strategies, moving toward professional custody options.
South Korea’s laws now emphasize insurance, compliance, and reserves for licensed custodians. These standards align with international models where expert custodians are trusted to manage blockchain-related risks effectively.
Key improvements in the custody framework are anticipated to fortify asset seizure, storage, and liquidation operations. This system aims to integrate secure wallet management and advanced blockchain monitoring across government departments.
Working with insured custodians is expected to minimize future losses and operational failures. This new approach reflects a push toward more robust management of state-held assets, ensuring secure and efficient oversight.
“By partnering with professional and insured custodians, we are reinforcing our commitment to security and transparency,” stated the NTS.
