Flagship course
Wallet Ledger Audit Studio
A cohort for compliance, risk, and product ops who must audit digital wallets with evidence that survives second-line scrutiny.
Who this is for
You already know what a digital wallet is. You need drills for defining populations across funding, spend, and settlement; testing controls that sit partly in vendor APIs; and writing findings that do not collapse under legal review.
Learning outcomes
- Build a wallet population map that auditors and engineers can both defend
- Design sampling plans that acknowledge rare high-value exceptions
- Test KYC refresh, pre-funding, spend limits, and settlement cutoffs with reproducible extracts
- Draft findings and residual-risk notes suited to Korean fintech operating contexts
Modules
Studio sequence
1 · Wallet topology & population design
Map nested wallets, merchant float, and consumer balances. Define what “in scope” means before anyone opens a spreadsheet.
2 · Onboarding & KYC refresh testing
Sample identity artifacts, refresh triggers, and exception aging. Practice documenting incomplete vendor packets.
3 · Funding, spend limits & freeze logic
Trace control points across pre-funding, velocity rules, and operational freezes after fraud alerts.
4 · Settlement cutoff lab
Reconcile delayed files, multi-rail cutoffs, and chat-thread exceptions into a durable workpaper.
5 · Finding writing & escalation judgment
Separate observation from finding. Practice language that holds when product pushes back.
6 · Capstone memo
Submit a full wallet audit memo. Instructors mark it like a second-line reviewer.

FAQ
Plain answers
Do I need coding skills?
Basic comfort with CSV filters or SQL helps in the settlement lab. We are not a programming course. If your team has no query skills, plan office hours early—this is a real limitation for some cohorts.
Is the course Korea-only?
Examples reference Korean supervisory expectations and local operating patterns, but international students join often. We flag where practices diverge rather than implying one rulebook.
Can my company pay by invoice?
Yes. Contact us for placement; we issue invoices offline. This website does not take payments.
What if I miss a live studio?
Recordings are available for two weeks. Capstone deadlines still stand unless you arrange an extension before the due date.
Course reviews
From Studio alumni
“Module four forced our settlement team to stop treating Slack as a control. Painful, accurate.”
Short take: the KYC sampling drill alone justified the fee. The mid-cohort homework spike is real.
