KYC System for Estonian Crypto Exchange

A fiat-to-crypto exchange operating out of Estonia needed a KYC system built to withstand European regulatory scrutiny. The exchange handled on-ramp and off-ramp flows between traditional banking and digital assets — a category under intensifying oversight as MiCA reshaped the EU framework for crypto-asset service providers. The client needed onboarding procedures that would satisfy both Estonian licensing expectations and the broader European compliance baseline, without slowing user activation to a halt. Designing this required reading the regulation closely, mapping it onto real customer flows, and producing controls that would hold up under audit — before any misstep could trigger a licensing review.

We built the KYC system as a regulatory framework first and a process second, anchoring every control in MiCA and Estonian requirements.

1. Regulatory analysis — conducted a structured review of MiCA provisions relevant to fiat-to-crypto operators, mapped them against Estonian licensing expectations, and identified the controls that needed to live inside the onboarding flow.
2. KYC procedure design — drafted end-to-end onboarding procedures covering identity verification, source-of-funds checks, and risk-based customer categorisation, calibrated for both retail and higher-risk profiles.
3. Compliance documentation — produced the internal policies, decision trees, and escalation rules that the exchange's team could operate day-to-day and present to regulators on request.
4. Implementation handover — walked the client through how each procedure plugs into their existing onboarding stack, so the system could go live without a second integration pass.
