Example: crypto & Web3 software for a gaming business in Sejong
Consider a gaming company in Sejong (government administrative city). A typical crypto & Web3 software engagement would start with wallets & custody, then tokenization, and finish the first release with compliance tooling — usually within 8–16 weeks.
Payments would run through Kakao Pay, data would be handled under Personal Information Protection Act, and success would be measured on daily active players, retention day 7 and payment success rate.

Regulators relevant to crypto & Web3 software in South Korea
Because crypto & Web3 software often touches regulated money flows or sensitive personal data, these authorities matter. We design controls with their expectations in mind; licensing remains with your regulated entity.
FSC
Korea's Financial Services Commission, which sets financial policy including the Virtual Asset User Protection Act. For crypto & Web3 software, custody, wallet security, disclosures and travel-rule messaging must match its rulebook.
FSS
Korea's Financial Supervisory Service, which inspects banks, fintechs and virtual-asset operators. For crypto & Web3 software, custody, wallet security, disclosures and travel-rule messaging must match its rulebook.
KoFIU (VASPs)
The Korea Financial Intelligence Unit, with which virtual-asset service providers must report and meet real-name account rules. For crypto & Web3 software, expect customer due diligence, transaction monitoring and suspicious-activity reporting to be designed in.

Personal Information Protection Act: compliance checklist for crypto & Web3 software

- Map every personal-data field to a lawful purpose under Personal Information Protection Act.

- Encrypt data in transit and at rest; restrict and log administrative access.

Hosting and data residency for crypto & Web3 software in South Korea
For clients in South Korea we usually host on AWS ap-northeast-2 (Seoul), Azure Korea Central, Google Cloud Seoul. The choice balances latency for local users, Personal Information Protection Act requirements on where personal data may be stored or transferred, and any sector rules your regulator sets. Backups and disaster-recovery copies follow the same residency decision.
