Where can I buy FRAX shares?

I'm curious about investing in FRAX, but I'm not entirely sure where to start. Could you please guide me in finding a reliable platform to purchase FRAX shares? I've heard about decentralized exchanges and centralized crypto exchanges, but I'm not sure which one is more suitable for FRAX. Are there any specific requirements or steps I need to take before making my first investment? Additionally, what are some of the key factors I should consider while evaluating a platform's reliability and trustworthiness? Your insights would be greatly appreciated.
