It is a kind of UPI that helps the user to transfer money from one country to another country instantly. The application should be similar to sendwave. I am sharing the link for a similar website link. It must follow the list of the countries where a person can transfer the money from one of its user panels to another account. The user can send the money from his/her bank account, debit card, Credit card, or UPI platform to others users' bank accounts.
I am expecting a response only from experienced guys who have experience with international money transfer applications.
