Hello Everyone,
I was wondering which method do big exchanges like binance, bitstamp, bitfinex ... generate bitcoin addresses, or any other altcoins addresses in mass for their users.
Possibly through a wallet installed in VPS then rely it to the website with json rpc as API ?

I guess most exchanges use some sort of hierarchical deterministic wallet as defined by BIP0032:

Hard to say though whether they use their own homebrewn implementation or base it on one of the existing implementations. Both approaches have their up and downsides, so this will likely differ from exchange to exchange and their respective tech stack.
