In early 2023, an online gaming platform that had operated primarily in US dollars announced support for Canadian dollars (CAD) and a suite of cryptocurrencies. That expansion brought a sudden spike in signups from Canadian users and crypto-preferring players. The change felt like opening a new wing of a house without checking whether the wiring and fire alarms still worked. What followed was an urgent re-evaluation of the platform's know-your-customer (KYC) verification process. This case study examines how accepting CAD and crypto created new KYC failure modes, the strategy chosen to manage them, a step-by-step rollout, measurable outcomes, and concrete lessons for any platform moving into multi-currency onboarding.
The KYC Verification Problem: Multi-Currency Onboarding Created Gaps
Before the change, the platform ran KYC workflows optimized for USD-based payments and standard credit card or bank transfers. The KYC pass rate was acceptable for the existing risk profile: 82% of applicants were verified in under 48 hours, false positives were 5%, and manual reviews consumed about 18 hours per week across two compliance officers.
Introducing CAD and crypto created three distinct problems:
- Cross-border risk layering: Canadian customers introduced foreign PEP (politically exposed persons) and sanctions screening cases that were previously rare. Some high-risk flows were not flagged until late in the payments lifecycle. Crypto-native anonymity: Crypto deposits elevated questions around source-of-funds and wallet ownership. The platform's KYC tools could verify identity documents, but had no integration with crypto transaction analytics to match on-chain behavior to claimed identity. Operational bottlenecks: Manual review volume surged by 230% within six weeks. Average verification time stretched from 36 hours to 96 hours, creating a churn point where 28% of new registrants abandoned the onboarding process.
Put another way: the platform's KYC system was a bicycle built for city streets. Adding CAD and crypto turned the route into a gravel trail and steep hills. The bike needed new tires, a better braking system, and a different gearset.
A Hybrid Compliance Strategy: Combining Risk-Based KYC and Crypto Transaction Monitoring
The compliance team opted for a hybrid strategy that married improved identity verification with specialized crypto transaction monitoring. Key design principles were:
- Risk-based screening: Move from a one-size-fits-all KYC gate to tiered verification paths depending on assessed risk and transaction thresholds. Crypto-aware tooling: Integrate on-chain analytics to validate wallet provenance, detect mixing/tumbler interactions, and flag high-risk counterparties. Automation with human oversight: Push low-risk decisions to automated checks while reserving complex cases for a trained manual review team. Fast feedback loops: Instrument metrics to measure verification latency, pass/fail reasons, and abandonment to iterate quickly.
This strategy required three technical components to be delivered in parallel: an identity verification upgrade, a crypto analytics integration, and a revamped case management interface for manual reviews. Each component would be tied to a revised risk-scoring engine that combined identity signals, payment method, geolocation, device fingerprinting, and on-chain indicators into a single composite score.
Rolling Out the New KYC Workflow: A 12-Week Implementation Plan
The team planned a 12-week rollout broken into four sprints. Below is a condensed timeline and the concrete tasks completed during each sprint.
Weeks 1-3: Discovery and Baseline Instrumentation
- Map existing KYC flows, decision points, and data fields. Collect baseline metrics: verification time (TAT), pass rates, manual review volume, and abandonment rate. Choose vendors: identity verification provider with document liveness checks and a crypto analytics provider with wallet scoring and clustering. Define risk tiers: low, medium, high - based on deposit method, deposit size, geo-risk, and history.
Weeks 4-6: Integration and Risk Engine Development
- Integrate identity verification API to capture document authenticity, name match, and liveness score. Integrate crypto analytics API to return wallet risk score, source-of-funds trace, and flags for mixing services. Develop risk-scoring rules and weightings. Example: identity confidence (0-100) x 0.4; wallet risk (0-100) x 0.4; geo-risk multiplier (1-1.5) x 0.2. Build automated decision rules: auto-approve low-risk, auto-decline high-risk, send medium-risk to manual review.
Weeks 7-9: Manual Review Tools and Playbooks
- Create a case management dashboard with clear context: identity artifacts, wallet traces, device history, and prior transactions. Develop standard operating procedures (SOPs) for manual reviewers. Include escalation paths for ambiguous on-chain evidence or conflicting documents. Train reviewers on interpreting wallet clustering charts, source-of-funds waterfalls, and common evasion techniques like chain-hopping or unhosted wallet deposits.
Weeks 10-12: Testing, A/B Rollout, and Monitoring
- Run the new workflow in shadow mode for two weeks to compare automated decisions against historical adjudications. Perform an A/B test: 50% of new Canadian and crypto-facing signups go through the new flow, 50% through the old flow. Instrument dashboards for TAT, false positives/negatives, abandonment, and cost per review. Launch the new workflow to all users after two weeks of stable metrics and reviewer calibration.
Throughout implementation the team used lightweight governance: weekly compliance reviews, a triage rotation for high-priority cases, and a changelog for each ruleset alteration. Total engineering effort: 2,200 hours across backend, frontend, and data engineering. Vendor costs in the first year: roughly $150,000 for identity verification volume and $120,000 for crypto analytics licensing. Internal incremental compliance labor: +1.2 FTE for manual reviews.
Verification Accuracy Improved From 82% to 96%: Concrete Results in 6 Months
Six months after the rollout the platform logged measurable improvements. Key outcomes were:
Metric Before After (6 months) KYC pass rate within 48 hours 82% 96% Average verification time (median) 36 hours 14 hours Manual review volume (weekly) ~240 cases ~70 cases Abandonment rate during onboarding 28% 9% Chargebacks/fraud-related losses (quarterly) $215,000 $63,000 Compliance operating cost (incremental) Baseline +1.2 FTE and vendor fees (~$270k annual)
Two examples illustrate how the new tooling changed outcomes. In one case a high-volume deposit came from a Canadian user who claimed salary as source-of-funds. Document checks passed, but crypto analytics revealed a recent inflow from an unhosted wallet linked to a mixing service. The automated risk score pushed the account to manual review where the reviewer requested additional bank statements and ultimately declined the onboarding. Losses were avoided because on-chain signals were combined with identity data early.
In another case a user from Ontario was initially flagged because their government ID had a low-quality scan. Liveness checks and device fingerprinting reduced false declines by enabling a secondary path: a short video verification plus a small micro-deposit from the user's Canadian bank. The user completed onboarding within 6 hours and went on to fund modest bets totaling $4,500 in the first month.
Five KYC Lessons for Platforms Adding Fiat and Crypto Support
Build a tiered verification model - Most users are low risk. Tiered KYC reduces friction for those users while concentrating resources on medium and high-risk cases. Make crypto analytics part of identity checks - Verifying a name and document is not enough when funds can move on-chain. Wallet provenance and clustering give context that identity alone cannot provide. Design for speed and feedback - Measurement matters. Shorten verification loops, report reasons for declines, and instrument abandonment causes to reduce friction. Keep human reviewers specialized - Manual review is expensive. Use automation to handle routine cases and keep reviewers focused on complex chain analysis, legal edge cases, and sanctions questions. Prepare for vendor risks - Relying on multiple vendors reduces single points of failure. Maintain failover modes and run periodic vendor audits and accuracy checks.Think of the KYC program like a river levee system. You can fortify the main wall, but water will find new gaps. Adding CAD and crypto was equivalent to changing the river's flow. The platform needed flexible barriers at multiple points - automated checks at the shoreline, human-controlled gates for storm surges, and continuous monitoring of the river's behavior.
How Your Platform Can Build a Robust Multi-Currency KYC Program
If you are considering adding CAD or crypto support, start with a short checklist and an initial budget estimate. Below is a practical blueprint you can adapt.
Step-by-step checklist
- Baseline your current KYC metrics: TAT, pass rate, manual reviews, abandonment. Identify new risk vectors introduced by each payment method (e.g., chain-hopping for crypto, cross-border PEP screening for CAD). List likely scenarios and estimated volumes. Choose identity and crypto analytics vendors. Run a pilot comparing outputs on historical cases. Define risk tiers and automated decision rules. Keep the rules auditable and parameterized so you can adjust quickly. Build or adapt a case management tool with clear evidence presentation and SOPs for reviewers. Run shadow mode and A/B tests before full rollout to measure improvements without disrupting existing users. Post-rollout: Monitor KPIs weekly, run quarterly vendor accuracy reviews, and update playbooks for emerging evasion patterns.
Estimated initial investment
- Identity verification vendor: $100k - $200k/year depending on volume. Crypto analytics provider: $80k - $150k/year for enterprise licensing and API calls. Engineering effort: 1,500 - 3,000 hours for integration and risk engine work (variable by architecture). Operational: +1 to 2 FTEs in compliance for the first 6-12 months while models are tuned.
These are ballpark numbers. Your actual costs will depend on user volumes and expected deposit sizes. A pragmatic way to manage budgetary risk is staged vendor adoption: start with identity verification and a limited crypto analytics module tuned for high-value deposits, then expand coverage as needed.
Accepting CAD and cryptocurrencies can open growth opportunities, but without a deliberate KYC redesign it creates exposure and user friction. In this case study the platform reduced verification time by more than half, cut fraud-related losses by roughly 70%, and lowered onboarding abandonment from 28% to 9% within six months. Those results came at a clear cost - both in vendor fees and added compliance staff - but the trade-off was faster, safer growth.
If you are planning a similar expansion, treat KYC as a product problem: instrument metrics, prioritize the fingerlakes1 user experience, and tie every rule change to measurable outcomes. With the right mix of automation, human expertise, and crypto-aware analytics, you can turn a compliance challenge into a competitive advantage. Think of it not as a one-time project but a continuous adaptation to new payment patterns and bad actors who never stop evolving.
