What are the basic elements of an event contract?

Always check your bank/electronic wallet/payment method of choice to confirm if you've received the full payment. Don't solely rely on payment proof provided by the buyer. Also, when you've a large number of orders, don't release your crypto based on an email or SMS notification. Scammers can send a fake SMS which at first glance looks like an SMS from a bank. Or they may send you a fake email, pretending to be from payment services such as Wise or AdvCash.
