Technical Postmortem: Syscoin Bridge Incident, Recovery, and Remediation
On June 7, 2026, Syscoin identified and responded to an exploit involving the UTXO-to-NEVM bridge.
The incident was caused by a cross-layer interpretation mismatch between Syscoin Core and the NEVM relay.
The funds were traced, returned, and burned to a standard OP_RETURN, restoring the reported coin supply to the expected value.
The bridge remains paused while final review, validation, and remediation steps continue.
