Private custody solution sought by South Korean tax authorities following crypto security breach
Following a wallet recovery phrase exposure that compromised government-controlled digital assets, South Korea's taxation authority is now searching for an external custodial service for confiscated cryptocurrency.
Following an incident in February where a publicly distributed document revealed a wallet recovery phrase that led to the illicit movement of seized digital currency, the National Tax Service (NTS) of South Korea has begun the process of choosing an external custody service provider for confiscated cryptocurrency holdings.
During the month of February, specifically on the 26th, the NTS inadvertently included a crypto wallet seed phrase within an official public statement, which subsequently resulted in the illicit movement of digital tokens worth approximately $4.8 million. The document in question contained a photograph depicting a Ledger cold storage wallet alongside a piece of paper displaying the mnemonic recovery phrase that had not been obscured or redacted.
According to sources with knowledge of the situation, as reported by ZDNet Korea, the taxation agency is currently examining a strategy to delegate the safekeeping of seized cryptocurrency to third-party providers and is in the process of developing qualification standards for potential custodians. The NTS has set a target to finalize the selection of a custody provider before the conclusion of the first six months of 2026.
The selection process will involve assessing prospective candidates according to multiple criteria, which include security protocols and standards, the scale and size of the organization, and whether the company maintains insurance coverage as mandated by South Korea's Virtual Asset User Protection Act, according to the ZDNet Korea report.
This initiative demonstrates that South Korean government agencies are attempting to establish formal procedures for the safeguarding of confiscated cryptocurrency following multiple mishandling incidents that revealed vulnerabilities in the methods used for storing and administering seized digital assets.
Newly established task force to manage custody provider selection process
According to reports, the process of selecting a custodial service provider will be overseen by a recently established task force dedicated to enhancing digital asset management infrastructure and systems.
The task force is said to be actively developing multiple programs and initiatives, which include the enhancement of procedural manuals that encompass the complete lifecycle of confiscated assets, spanning from initial seizure through secure storage to eventual liquidation and sale. The group would additionally perform evaluations and provide training for personnel involved in these processes.
Furthermore, the team is making preparations to create a specialized department that will be responsible for managing cryptocurrency-related operations and responsibilities.
A representative from the NTS explained that because cryptocurrency represents a relatively recent development, current responsibilities are distributed among multiple departments. Nevertheless, according to ZDNet Korea's reporting, preparations are currently in progress to establish a consolidated organizational unit to handle these matters centrally.
Seed phrase exposure by NTS triggers multi-agency investigation
The exposure of the NTS's wallet seed phrase, combined with an additional custodial mishap in which law enforcement officials from Seoul's Gangnam district reportedly misplaced 22 BTC that had been seized, has prompted government authorities to initiate a comprehensive inter-agency examination of confiscated cryptocurrency asset management practices.
In early March, specifically on March 1, Koo Yun-cheol, who serves as South Korea's Deputy Prime Minister as well as Minister of Economy and Finance, made an official announcement regarding a multi-agency investigation into the procedures and protocols that the government currently employs for managing and handling seized digital assets.
