Evidence pack practice in Module 8 changed how we hand files to external reviewers. We still wish Module 7 had a second lab hour.

Flagship program
Ledger Integrity Practicum
A six-week cohort where fintech operators reconstruct transaction paths, pressure-test controls, and document findings that survive partner and auditor questions.
Learning outcomes
- Rebuild a multi-rail payment story from raw exports
- Separate authorization noise from clearing truth
- Write scoped findings with sample method and limits
- Brief risk and engineering without overclaiming certainty
- Spot when tooling — not process — is the bottleneck

Integrity vocabulary
Shared definitions for pending, cleared, reversed, and orphaned states.

Instructor
Yuna Seo

FAQ
Who is this for?
Operators, junior auditors, and product analysts who already touch reconciliations. Pure beginners to finance concepts may struggle in weeks three and four.
Is this a certification for Korean regulators?
No. Smartwebkit provides education and practice. We do not certify compliance with any regulator or exchange listing requirement.
What is a real limitation of the program?
We cannot give you production access to your own systems. Labs use synthetic and redacted samples. If your stack is highly custom, Integrity Studio may fit better than the public cohort.
How much weekly time should I reserve?
Plan for roughly five hours: one live session, one lab block, and async critique.
Reviews from this program
★★★★☆
Solid on settlement windows. The peer critique stung in a useful way — my first finding draft was too absolute.
