Hi team, i'm almost done with my App - Other Me, which is an Avatar creation and conversational RPG which use AI Generation. To pay for images and videos, we need to buy credits so i can pay my AI services. Payment with Nimiq Pay is working well already. My questions are in 3 areas: Safety: currently we are using Nimiq Pay local (phone side) to allow sign transactions and is all good but I want to migrate to server side for security (avoid local balance manipulation = hacking the code). For the Hackathon i think the risk is low but I want to get your feedback on it; local or server? Marketing: I will start promotion of the App this week for the competition. I will focus on Web3 Nimiq community first and then i was planning to expand it to normies. I include already 2 navigation buttons for them to learn about Nimiq and to download the Nimiq Pay App. Also provide some free credits and generations of avatars so they can test it with just an email log in. My question is if there's any restrictions to use log in with Google account email for testing the app? Pricing: For testing, i was running "credits retail price"/100 to minimize cost since i already connected to production main network, but now that i will start with the marketing for users, I was planning to put back the real prices so i don't lose money when they generate video. My question is for the hackathon, do i keep lower prices for judges and early user may be x/5 or do i put the actual price from the start since the idea is for validating the model? FYI, i already have a promo of 150% credits if paid in NIM Thanks for your help and advice. Regards, Luis
