Supplementary Appendix A. Documented Vietnamese Crypto Case Universe and Selection Logic

This appendix reports the bounded case universe identified for the baseline stress-test design as at 14 August 2026. Candidate cases were located through secondary case discovery and official-source searches, but inclusion in the documented universe required a primary Ministry of Public Security or police investigative/procedural source. The universe is not claimed to be statistically exhaustive of all Vietnamese crypto misconduct. The six analytical cases were selected purposively to maximise variation in regulatory mechanism while minimising duplication across issuer-centred, platform-centred, cross-border, stablecoin and hybrid/protocol-mediated configurations.
