AML Obligations

  • VASP registration with KoFIU under the Act on Reporting and Using Specified Financial Transaction Information (amended 2021) is mandatory for the custodial wallet provider (kr.licensing.vasp, kr.aml.act-on-reporting-and-use)
  • ISMS certification from KISA required (kr.licensing.vasp, kr.aml.korea-internet-security-agency-kisa)
  • Mandatory real-name verified bank account partnership (critical bottleneck — only 5 exchanges achieved this) (kr.licensing.vasp)
  • Suspicious transaction reporting (STR) to KoFIU for AML/CTF compliance (kr.aml.korea-financial-intelligence-unit-kofiu)
  • KYC/AML obligations under the Act on the Protection of Virtual Asset Users (2024) for customer onboarding (kr.aml.act-on-the-protection-of)
  • The SaaS provider, as the VASP, bears primary AML obligations — white-label clients may not be separately registered, shifting compliance burden to the custody provider (kr.licensing.custody)

Key Restrictions

  • Only 5 exchanges have achieved the real-name bank account partnership bottleneck (Upbit, Bithumb, Coinone, Korbit, Gopax); a custodial wallet SaaS operator would need such a partnership (kr.licensing.vasp)
  • KRW 3B (~$2.2M USD) minimum equity capital required for exchanges under VAUPA; unclear whether a pure custodial wallet SaaS qualifies as an 'exchange' for this threshold — legal interpretation needed (kr.licensing.vasp, kr.licensing.legislation-virtual-asset-user-protection-act-vaupa)
  • 100% cold storage for reserves required for custody operations (kr.licensing.custody)
  • Compensation reserves (insurance/indemnity) mandatory under VAUPA for custodial functions (kr.licensing.custody, kr.licensing.legislation-virtual-asset-user-protection-act-vaupa)
  • ICO effectively banned since 2017 via administrative guidance — affects any token-related custody or issuance (kr.licensing.exchange)
  • Token listing requires exchange self-assessment, which could affect which assets the custodial wallet supports (kr.licensing.exchange)

Key Risks

  • Real-name account bottleneck is the single greatest operational risk — without a partnership, the model cannot legally operate (kr.licensing.vasp)
  • Regulatory ambiguity on whether a pure custodial wallet SaaS (non-exchange, non-trading) fits under the exchange classification with the KRW 3B capital threshold (kr.licensing.vasp)
  • Upcoming Digital Asset Basic Act (proposed early 2026) may introduce additional custody-specific licensing or supervision, creating regulatory transition risk (kr.aml.upcoming-digital-asset-basic-act)
  • VAUPA imposes severe penalties (including life imprisonment for gains over 5B KRW) for market manipulation/insider trading — custodial wallets handling user assets must have strong internal controls (kr.aml.act-on-the-protection-of)
  • White-label model creates AML attribution risk — unclear whether SaaS provider or client bears STR/KYC duties; KoFIU registration likely falls on the entity with key control (the custody provider) (kr.licensing.custody, kr.aml.korea-financial-intelligence-unit-kofiu)

Evidence

This verdict synthesizes the following facts. Each fact links to its primary source(s).

licensing 30% confidence

FSC — Financial policy and regulation

licensing 30% confidence

KoFIU — Financial intelligence, VASP registration

licensing 92% confidence

Act on Reporting and Using Specified Financial Transaction Information — VASP reporting to KoFIU and AML/CFT duties added by Law 17113 of 24 March 2020 (in force 25 March 2021); Law 21358 of 19 February 2026, in force six months after promulgation, adds major shareholders to the report and new refusal grounds on financial soundness, social credit and internal controls (Art. 7(1)(1-2), 7(3)(5)-(6)).

licensing 90% confidence

Virtual Asset User Protection Act (Law 19563 of 18 July 2023, in force 19 July 2024) — user deposit and asset protection (Arts. 6-7), mandatory insurance, mutual aid or reserves against hacking and outages (Art. 8; FSC rule proposal minimum KRW 3 billion for KRW-market exchanges and KRW 500 million for other providers, a cover requirement rather than equity capital), and prohibition of insider trading, market manipulation and other unfair trading (Art. 10).

licensing 88% confidence

A virtual asset service provider must report to the Korea Financial Intelligence Unit (Act on Reporting and Using Specified Financial Transaction Information, Art. 7), which may refuse the report without ISMS certification or a real-name verified bank deposit and withdrawal account unless KoFIU exempts the provider (Art. 7(3)(1)-(2)); since Law 21358 of 19 February 2026 the report also covers major shareholders; an accepted report is valid for 3 years and must be renewed (Enforcement Decree Art. 10-15); KoFIU listed 28 providers with accepted reports as of 30 September 2026.

licensing 90% confidence

Under the Virtual Asset User Protection Act a provider holding users' virtual assets must keep them segregated from its own and actually hold the same type and quantity (Art. 7(2)), and must store offline a share set by decree (Art. 7(3)): the Enforcement Decree sets at least 70%, at the ratio the FSC fixes by notice (Decree Art. 11(1)), and the FSC's 11 December 2023 rule proposal set that ratio at 80%; user KRW deposits must be placed with a bank or similar custodian at 100% or more of the total (Decree Art. 8(3)), and insurance or reserves against hacking and outages are mandatory (Act Art. 8).

licensing 90% confidence

A virtual asset exchange must report to the Korea Financial Intelligence Unit under Article 7 of the Act on Reporting and Using Specified Financial Transaction Information, and KoFIU may refuse the report if the exchange lacks ISMS certification or does not deal through a real-name verified deposit and withdrawal account linking the exchange's and its customers' accounts at the same bank (Art. 7(3)(1)-(2)); under the Virtual Asset User Protection Act an exchange must monitor abnormal trading continuously and notify the FSC and FSS of suspected unfair trading (Art. 12).

aml 92% confidence

Under Article 7(1) of the Act on Reporting and Using Specified Financial Transaction Information, a virtual asset service provider must file a report (신고) with the Korea Financial Intelligence Unit before operating, and is subject to the Act's customer due diligence and suspicious-transaction reporting duties from 25 March 2021 (Law 17113 of 24 March 2020); operating without a report carries up to 5 years' imprisonment or a fine of up to KRW 50 million (Art. 17(1)).

aml 95% confidence

The Virtual Asset User Protection Act (Law 19563, enacted 18 July 2023, in force 19 July 2024) prohibits the use of material non-public information, market manipulation and fraudulent unfair trading in virtual assets (Art. 10); violators face at least 1 year's imprisonment or a fine of 3 to 5 times the gain (Art. 19(1)), rising to life or at least 5 years' imprisonment where the gain or loss avoided is KRW 5 billion or more (Art. 19(3)), and the FSC may impose a penalty surcharge of up to twice the gain, or up to KRW 4 billion where no gain can be calculated (Art. 17(1)).

aml 92% confidence

The Korea Financial Intelligence Unit receives and accepts virtual asset service provider reports under Article 7 of the Act on Reporting and Using Specified Financial Transaction Information (28 providers accepted as of 30 September 2026), receives suspicious transaction reports, which must be filed without delay (Art. 4(1)), and supervises, inspects and sanctions reporting entities for AML compliance (Art. 15).

aml 88% confidence

Information security management system (ISMS) certification, which a virtual asset service provider needs for its KoFIU report to be accepted (Act on Reporting and Using Specified Financial Transaction Information Art. 7(3)(1)), is granted under Article 47 of the Information and Communications Network Act by the Minister of Science and ICT, who may have the Korea Internet & Security Agency (KISA) or a designated certification body carry out certification audits and issue certificates (Art. 47(6)).

aml 90% confidence

The Digital Asset Basic Act (디지털자산기본법안, bill 2210736) was proposed on 11 June 2025 by Rep. Min Byung-duk and 36 other members and referred to the National Policy Committee; as of 14 October 2026 the National Assembly bill record shows no committee or plenary decision, and the FSC described stablecoin legislation as pending on 4 September 2026.

This verdict was produced by an AI model from the underlying facts. Confirm with counsel before relying on it for material decisions.

Conditional — a custodial wallet SaaS can operate in Korea only if it obtains VASP registration with KoFIU, ISMS certification, a real-name bank account partnership (severe bottleneck), meets segregation/insurance/cold-storage requirements under VAUPA, and complies with AML/CTF obligations; the provider bears primary AML responsibility, and the KRW 3B minimum capital requirement for exchanges creates interpretive risk for custodial-only operators.

  • What custody license / qualified-custodian status applies?
  • What segregation, insurance, and proof-of-reserves rules apply?
  • What AML obligations attach to the SaaS vs the white-label client?
