Solana AI Payment System Can Leave Sellers Unpaid After Delivery, Researchers Find

WHY IT MATTERS

When you buy something online, you expect that once the seller ships your item, they get paid. Blockchain payment systems are supposed to make this even more reliable by using code — called smart contracts — to automatically handle both sides of a deal. Think of it like a vending machine: you put in money, and the machine gives you a snack, all in one step. This story is about a system on the Solana blockchain that processes payments very quickly using artificial intelligence, but has a flaw where the "vending machine" can give you the snack without actually collecting your payment — leaving the seller out of pocket. This matters because one of the main reasons people use blockchain for payments is the promise that the technology itself guarantees fairness, without needing to trust the other person. If that guarantee breaks down, it raises questions about how much users can rely on these automated systems.
