KYC/AML for crypto-fiat gateways in emerging markets

Been pondering the real-world operational challenges for smaller fintechs trying to establish crypto-fiat gateways in, say, Southeast Asia or parts of Africa. The regulatory landscape can be incredibly fragmented, often unclear, and sometimes even contradictory between different ministries or central banks within the same country. Beyond just meeting the basic KYC/AML checks, what are some of the less obvious red flags or common pitfalls folks have encountered specifically when dealing with high-volume, low-value transactions that are characteristic of these markets? It feels like the standard European or North American AML frameworks, while robust, don't always translate cleanly, especially when local payment methods or identity verification processes are less formalized. Is there a better framework or set of best practices for identifying potential money laundering beyond the typical transaction monitoring when you're in a market that's still maturing regulatory-wise?
