If the main idea is to create an app that uses a Safe coin for sellers to make online payments, which coin would you like to use? Are you going to use one of the coins on the market? Or will you create a new "Safe coin"?
If you want to create a new coin, this means that you need to create a blockchain for the coin, this means that you need a team because this is difficult for one person to do, and you also need a business plan of several stages and provide the necessary funds to complete each stage.
This costs a lot of money so have you ever thought about how you will provide the money needed to create such a project that involves creating a new coin and a new blockchain?
I think OP is not serious about what he made a topic here in this forum section. Because first of all, his details about the inquiries he is planning on the crypto exchange are lacking. Then his last post was last December 20, 2022,
In addition to that, his last active post was also this past January 11, he didn't even look at the topic he did to see what answer there is already here for what he wanted to know.
We can't conclude with certainty about that OP maybe is ain't serious about his project that made him created the post about, perhaps it could be that someone from the forum might have privately approached him with a solution to what he's looking for and OP might have bought in to it to work with it without coming back to his thread to notify about his current status on the issue. Which if that's the case, then it's wrong of him.
just my personal thought by the way!
