The bridging vulnerability can be recovered and destroyed—handled with textbook-level crisis management—but the figure of 5 billion still makes people gasp in shock.

CryptoWorld News: Syscoin has released a bridge security incident report, disclosing a UTXO-to-NEVM bridge vulnerability that resulted in approximately 5 billion SYS tokens being released without authorization on the UTXO side. The related funds have been returned to the official recovery address and destroyed using the standard OP\_return method. The SYS supply reported on-chain has now been restored to the expected value. At present, the bridging functionality is suspended, and Syscoin is working to fix the cross-layer parsing defect.
