Hello, I am familiar with Discord bots and have started making a Discord bot with PayPal integration before, however, the client decided to cancel the project. I am familiar with both the Discord and PayPal API and will be happy to program a "coins" system that users can deposit into using PayPal.
I have also programmed many Discord bots with other functions, such as moderation and image scanning.
Furthermore, I will be fast and efficient, and I will keep in constant contact, replying within 12 hours to any messages or questions you may have. The program will be written using node.js/javascript. I will provide instructions to you on how to host the bot yourself and will gladly set it up for you on your server if you wish that.
