Syscoin has published a security incident report addressing a vulnerability in its UTXO-to-NEVM bridge, which led to the unauthorized release of approximately 5 billion SYS tokens. The affected tokens have been returned and destroyed using the OP_RETURN mechanism, restoring the on-chain SYS supply to its expected level. The bridge remains suspended as Syscoin finalizes its review and remediation efforts to fix the cross-layer parsing vulnerability.
