Multi-currency support is trickier than it sounds. You've got exchange rate management, different regulatory requirements per region, various local payment methods to integrate, and then there's the settlement complexity. Most off-the-shelf solutions force you into their ecosystem which limits your flexibility down the road. I'd suggest looking for a platform that offers modular wallet components so you can customize the experience for each market while maintaining a unified backend. Also make sure whoever you work with has actual experience with cross-border transactions, not just theoretical knowledge.
