I components should be implemented for the platform to operate securely and stably. It is important for me that the exchanger supports stable operation with popular cryptocurrencies (Bitcoin, Ethereum, USDT) and fiat currencies (USD, EUR, etc.). It is necessary to implement a user verification module (KYC/AML), connection to reliable payment gateways, protection from DDOS attacks, and an asset storage system (including cold wallets). I am interested in what technologies, frameworks, and architectural approaches are currently considered the best for this kind of project? Should I develop a platform from scratch or use white-label solutions, and what are the pros and cons of each approach?

If you are thinking about developing your own exchanger with fiat and crypto support merehead.com/blog/fiat-to-crypto-exchange-development/, you should definitely understand all the technical and legal nuances in advance. I recently encountered this myself when launching a project - it seems that everything is simple: connect the API and work. But in fact, you need a well-thought-out architecture, reliable payment gateways, a security system, AML / KYC support, etc. I recently found a very useful article on this topic - here. Everything is described there: how to build an architecture, how to choose liquidity providers, what functions are important for the first version of the product. I especially liked that they even touched on the legal aspects and gave advice on launching in different jurisdictions. If anyone here is interested in this topic, I recommend reading it, it will save a lot of time and protect you from mistakes. I myself emphasized a lot from there for myself.
