It’s a payment swapping tool used by Merchants. So basically said business A wanted Bitcoin but accepted Monero. For example let’s say someone like @Oshi that prefers Bitcoin but wanted to accept Monero from customers, he could use https://trocador.app/en/ to swap the monero into Bitcoin on his store front. It’s also implemented into cake wallet. (Sorry for tagging Oshi but I wanted to give an example)
