That's for the most useless post I've seen in a while.
Well, I really don't know why I should bother to help you since you've insulted me already and you clearly have no understanding about this industry. But on the off-chance this information helps your future customers then it might be worth it:
Coin daemons weren't designed to be used as a deposit and withdrawal system for a website. It was assumed that wallets would be run by users who managed their own private keys. The reason why its such a moronic idea to use a coin daemon for a website is multi-faceted but in brief:
1. Anyone who hacks the server has full access to all the funds and there's nothing you can do about it.
2. The RPC server that full node software provides is buggy and doesn't scale. This means that calls you make will mysteriously timeout under load / randomly.
What you are proposing to do hasn't been recommended since 2012 (or ever really) and the exact design has already lead to the theft of money worth over a billion dollars. Since then a lot of security best practices have become standard for storing and managing cryptocurrencies.
Hardware wallets help to stop coins from leaking from web servers and allow for sane withdrawal limits. While multi-signature allows for N-factor authentication and helps to give the user more control over their money. Coin daemons aren’t designed to support any of that because they already assume a single user is using the software in a secure environment they control (and not under the assumption of a system supporting assets on behalf of multiple users on an Internet-facing website.)
However writing in nodejs a completely separate deposit, wallet management, and withdraw code for each coin seems overkill.
So you're a complete amateur. You have no clue at all how to solve a basic problem in blockchain engineering and you're already looking for ways to cut corners. If you're writing another crapcoin exchange (and I have a feeling you are) - a person like you really has no business writing any code that will touch other people's money until you at least understand the basics of how security is done in this industry and wtf you are doing.
If you ignore my advice I can see you very quickly becoming taught this lesson by someone far less forgiving. But by that point it will be too late - both for your customers and your reputation. Believe me, this industry is lined by the corpses of countless drive-by wantrapeneurs who thought they could get rich by hacking together a few shitty scripts and cutting corners.
