So at exchanges, so many coins. For each of them, they provide deposit addresses.
If you are engineer, need to implement that, how to do?
Maybe using that coin's daemon?
How is specific procedure of it?
To be able to generate a wallet address, you need to understand how it works and its format.
As it was said, Bitcoin addresses are a specific format of an edcsa (using secp256k1 parameters) public key, formatted a certain way, as described on
this page: Technical background of version 1 bitcoin addresses. You must also take a look at
the wallet import format which will help you to import private keys in Bitcoin Core and other wallets. Note that more recent addresses - p2sh & bech32 - are a little different and you will need to do more research about it.
You can either have one daemon to generate/handle those keys, or just a simple script that'll do it on demand, as this is a very simple task to do which doesn't use much cpu. The main problem in the process is to correctly protect the private keys.
