South Korea’s National Police Agency is moving to standardize how seized cryptocurrencies are stored and managed, drafting guidelines that cover privacy-focused assets as authorities seek more robust asset handling. The initiative comes as investigations increasingly involve digital assets, and past incidents exposed gaps in custody processes. The KNPA’s draft directive outlines compliance requirements at each stage of crypto seizure, including the management of software wallets and private keys. The move mirrors a broader push among regulators to tighten control over the lifecycle of digital assets once they land in government custody, and it places a spotlight on the risks tied to custody for privacy-focused tokens and mainstream coins alike.

Key takeaways

The KNPA’s draft directive aims to standardize seizure handling, with explicit procedures for wallet addresses, private keys, and custody workflows across cases involving digital assets.
Plans to select a private custody provider are scheduled for the first half of 2026 after three bidding attempts in 2025 failed to yield a suitable partner.
Budget constraints are a recurring challenge, with a reported allocation of 83 million won (about $55,600) to manage seized crypto assets, underscoring risk despite limited funding.
A phishing-related custody incident intensified scrutiny earlier this year when government-held Bitcoin disappeared from prosecutors’ custody, prompting a rapid push to strengthen controls.
Historically, authorities have disclosed that a substantial share of seized crypto comes from the Bitcoin (CRYPTO: BTC) and Ether (CRYPTO: ETH) ecosystems, with multi-year totals used for public treasuries and ongoing cases.
The policy also contemplates privacy-focused tokens, such as Zcash (CRYPTO: ZEC), signaling a broader risk-management approach that extends beyond the most liquid assets.

Market context: The move to codify seizure custody aligns with a broader trend of tightening regulatory oversight around digital assets, as authorities increasingly require auditable chains of custody and documented controls. In a market where liquidity and risk sentiment can shift quickly, formal custody arrangements may reduce the potential for asset loss and improve transparency during investigations.

Why it matters

<pThe KNPA’s push to formalize seizure custody reflects a structural shift in how public agencies treat digital assets once they enter the investigative pipeline. By moving away from ad hoc storage to a documented, auditable framework that includes wallet addresses and private keys, authorities aim to curb the kind of misplacement risk that has surfaced in recent years. This is particularly salient for privacy-focused tokens, which can complicate tracing and compromise chain-of-custody procedures if not properly accounted for. The directive’s inclusion of such assets signals a broader risk-management posture that regulators are starting to treat as routine rather than exceptional.

<pThe plan to appoint a private custody provider in 2026 marks a pivotal moment in the evolution of government handling of seized crypto. After failed bids in 2025, the KNPA has signaled that external expertise will be essential to maintaining a robust custody regime, especially as cases grow in volume and complexity. Budget constraints—83 million won, or roughly $55,600—highlight the ongoing tension between the need for professional storage solutions and the resources available to public agencies. This financial constraint could influence the speed and scope of the forthcoming procurement process, potentially shaping which firms are able to participate and what services are feasible within the stated budget.

<pBeyond the mechanics of storage, the policy framework is designed to address the human element of custody. A police spokesperson emphasized that investigators now need systematic guidelines and adequate support as investigative paradigms shift from warehouses to wallet addresses and private keys. This reflects a practical acknowledgement that preserving the integrity of seized assets requires tools, training, and clear operational protocols that reduce the risk of error or theft during handling and transfer.

What to watch next

The KNPA will finalize the bid process for a custody provider in the first half of 2026, clarifying who will manage seized assets going forward.
A formal, published directive detailing custody procedures, wallet management, and asset tracking is expected to accompany the provider selection, offering a concrete playbook for investigators.
Regulatory and policy scrutiny around privacy-enhanced assets such as Zcash (CRYPTO: ZEC) will likely shape custody guidelines, especially in relation to privacy-preserving features and auditability.
Precedents from high-profile custody cases—where assets were temporarily lost or mishandled—will inform risk controls and internal training programs for Korean law enforcement and prosecutors.

South Korea tightens crypto custody protocols amid seizure challenges

The National Police Agency’s forthcoming custody framework is poised to redefine how authorities handle digital assets from the moment of seizure through eventual disposition. By mandating systematic governance of wallet addresses, wallet access controls, and the private keys that unlock asset movement, the draft directive seeks to prevent the kind of misplacement or mishandling that has plagued past cases. In a jurisdiction where public authorities have seized substantial sums in crypto over the years, the ability to demonstrate a clear chain of custody is not merely an administrative concern—it is a matter of due process and public accountability.

In aggregated terms, seizures over the past five years have been substantial, with estimates indicating the value of seized crypto totaling around 54.5 billion won (roughly $36.5 million). The lion’s share of that amount has come from Bitcoin (CRYPTO: BTC) and Ether (CRYPTO: ETH), with about 50.7 billion won in Bitcoin and 1.8 billion won attributed to Ether. This composition underscores the importance of asset-specific storage protocols, as the differing liquidity profiles, transaction speeds, and security considerations of each asset class demand tailored custody solutions. The emphasis on privacy-focused tokens, such as Zcash (CRYPTO: ZEC), further complicates custody, given the additional considerations for privacy-preserving transactions while maintaining verifiable audit trails.

The phishing episode that catalyzed renewed attention to custody didn’t just expose a technical vulnerability; it highlighted the human and procedural gaps that persist in asset handling. Authorities confirmed that around 320 Bitcoin disappeared from prosecutors’ custody during an August 2025 investigation. Although the unknown actor returned the coins in February of the following year, the episode culminated in a March decision to tranfer proceeds totaling roughly 21.5 million USD to the national treasury, illustrating how seized assets transition into public coffers when custody is breached. The incident has underscored the need for formalized, auditable procedures that can withstand the scrutiny of investigations and public reporting.

As the KNPA moves forward, the planned engagement with a private custody provider could help institutionalize best practices across the asset lifecycle—from secure key management to robust access controls and transparent reporting. The procurement effort in 2026, following unsuccessful bids in 2025, signals a shift toward professional asset stewardship, even as budget constraints loom. The combination of regulatory intent, practical risk considerations, and the evolving landscape of digital-asset custody will shape how Korean authorities respond to future investigations and how market participants perceive the reliability of government custody in high-stakes cases.
