Payy Bridge Exploit Freezes Crypto Cards and Puts User Balances at Risk

WHY IT MATTERS

A "bridge" in crypto is like a translator that moves your money between different systems — for example, from a blockchain to a traditional payment card. When hackers find a weakness in that bridge, they can potentially steal or freeze the funds passing through it. This incident matters because crypto cards are one of the ways everyday people use cryptocurrency for regular purchases, and an exploit like this shows that trusting a third-party service with your crypto carries risks. Think of it like a bank's ATM network going down, except in this case there are also concerns that the money in the accounts may have been compromised. For beginners, this highlights the importance of understanding the difference between holding your own crypto in a personal wallet (called "self-custody") versus leaving it on a platform where someone else controls it.
