Syscoin releases a report on the bridge security incident, funds have been recovered and destroyed, and the cross-layer parsing defect will be fixed

Syscoin released a bridge security incident report, disclosing details of the UTXO-to-NEVM bridge vulnerability incident, which reportedly led to approximately 5 billion SYS being unauthorizedly released on the UTXO side. The related funds have since been returned to the official recovery address and destroyed through the standard OP_RETURN method, making them unusable by the protocol again. The on-chain reported SYS supply has been restored to the expected value, and the bridge function remains suspended while the team completes the final review and fixes.

Syscoin pointed out that it will fix the cross-layer parsing defects. The core lesson from this incident is that cross-layer systems must uniformly standardize data processing, and any ambiguous bridge proof should be considered a default failure.
