South Korea Moves Seized Crypto to Private Custodians After $4.8M Wallet Leak

TLDR

• South Korea’s NTS seeks private firms after $4.8M crypto leak.

• Wallet seed exposure sparks overhaul in government crypto custody.

• Selection favors security, insurance, and institutional experience.

• Specialized task force to centralize seized crypto management.

• New system aligns with global standards for digital asset safety.

South Korea’s National Tax Service is seeking private custody providers for seized cryptocurrencies after a major security breach. On February 26, the agency accidentally exposed a wallet seed phrase in a public release, allowing unauthorized transfers of $4.8 million in digital assets. Authorities are now formalizing custody procedures to prevent future losses and strengthen oversight.

The leak involved an unredacted image of a Ledger cold wallet and its mnemonic phrase.  The incident highlighted weaknesses in South Korea’s government-held digital asset management. The agency plans to outsource custody to professional firms with proven security systems and insurance coverage.

South Korea’s approach comes amid growing regulatory demands for proper handling of virtual assets. The National Tax Service aims to complete the selection of a custodian within the first half of 2026. This move signals a shift toward institutionalized management of confiscated cryptocurrencies in South Korea.

Selection Criteria and Custody Oversight

The National Tax Service is developing detailed criteria to evaluate potential custody providers. Security standards will include advanced cybersecurity, multi-signature wallets, and secure hardware storage. Firms must also maintain insurance under South Korea’s Virtual Asset User Protection Act, ensuring coverage for operational failures.

Company size and financial stability are additional factors in South Korea’s evaluation process. Providers must demonstrate experience with large-scale digital asset management and government or institutional clients. Operational transparency, auditing procedures, and disaster recovery capabilities will also be key requirements for selection.

South Korea’s NTS is forming a specialized task force to oversee the custody selection. The group will establish operational protocols, personnel training, and lifecycle management for seized digital assets. This centralized oversight aims to unify responsibilities currently spread across multiple departments.

Background and Regulatory Context

South Korea’s wallet leak follows prior custody failures, including the loss of 22 BTC by local police authorities. In response, the government launched a cross-agency probe to assess asset handling and prevent future errors. The initiative represents a structured effort to secure South Korea’s growing volume of seized cryptocurrencies.

The Virtual Asset User Protection Act provides the legal framework for South Korea’s custody reforms. It mandates insurance, compliance, and reserve requirements for all regulated service providers. South Korea’s regulatory strategy mirrors international trends where governments increasingly rely on specialized custodians for digital assets.

The new custody system will standardize procedures for seizure, storage, and liquidation of cryptocurrencies. South Korea aims to improve technical management, including wallet handling, key storage, and blockchain monitoring. The initiative also positions South Korea to expand digital asset custody services across multiple government agencies.

South Korea’s National Tax Service expects the transition to private custodians to reduce security risks and operational failures. This move signals stronger institutional frameworks for cryptocurrency enforcement. The adoption of professional custody services reflects South Korea’s commitment to secure and regulated management of seized digital assets.
