no, its my own website node-vuejs
I mean it would be against the concept of app

for now i have implemented it via coinbase api, but still looking for a better option, I don’t really want to keep all the money on coinbase

I perfectly understand that you can’t trust online wallets, but I don’t have the money and knowledge to immediately make a server wallet with many currencies at once, my project is already 80% ready, but with this part it turned out to be a mess, I contacted binance support, they said that it is impossible there, but after studying the coinbase documentation, I believe that it is quite possible with a business account. but i'm still looking for third-party alternatives.

this will greatly simplify the development of the application
this is exactly what I planned, people deposit their money from the outside to the my master wallet and then transactions inside the application occur simply by rewriting from one database to another
here is the problem, I can imagine how to manually make bitcoin wallets using the ready-made bitcoin-core package, but I don’t quite understand how to manually screw other currencies, besides, this will greatly increase the load on the server (assumption). therefore, I am looking for a third-party service with good api that could provide such an opportunity to generate multiple addresses for one currency and then simply assign each address to a specific user

Yes, bitcoin core fits well with what I have described, but I would like the user to have the opportunity to use other currencies(4-5 popular currency ada, eth, usdc), unfortunately, the specifics of the my site do not allow using the payments services(coinpayments or btcpayserver) that you mentioned. at the moment I'm leaning towards binance with its ability to create sub-accounts in a business account via api.

hello, I am looking for a good online wallet with the ability to create multiple accounts for users.
I found something similar to this in coinbase, through api I can create addresses for each user, also identify the user through notifications from coinbase, but are there any better alternatives for this?

Hello, guys. I have created localbitcoin bot, which u can free download from github.
https://github.com/RobinsonNikolay/LocalbitcoinBot

Bot works through system terminal/console.

All settings u can make in file account.json

This free version of the bot only works with russian payment system QIWI.
You can enter as many qiwi accounts as you like, the bot will use them one at a time.
You must create two app localbitcoins on the page https://localbitcoins.com/accounts/api/
and issue a token for each qiwi account.
In the login column write your nickname in localbitcoins
Also buy and sell orders should already be created on the locale.
The bot itself will not create them, it will edit the price every half minute.

Ask any questions in the telegram @RobinsonNikolay
By the same principle, bots are available on other payment systems in localbitcoins (for a fee)
