This project turned out more complex than expected. Backend became a major blocker, and without it the frontend could not progress, meaning the design would have needed to change.
In the end, 220k+ users completed the flow, keeping the platform compliant with virtually no UX complaints. The KYC widget also became a long-term entry point, later reused for UK compliance, Proof of Residence, Proof of Identity, Tax ID, and other regulatory flows.
Users can now update their name and address without contacting support. This improves the experience and significantly reduces agent administrative workload, allowing them to focus on higher-risk compliance tasks.
