# Siren (SIREN) Quantum Readiness Report

> Siren has a QRI score of 7.71/100 and is assessed at Stage 1 (Quantum Risk Assessed) with medium evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: BEP-20 token inheriting L1 quantum security posture; token-specific admin/governance keys evaluated separately.

Siren (SIREN) is a standard BEP-20 meme token on BNB Chain with renounced ownership. Under QRI Section 7.2 (Token Inheritance), it inherently shares BNB Chain's QRI score of 19/100 (Stage 1: Quantum Risk Assessed) per external reference (LayerQu). BNB Chain has acknowledged quantum risk and published a detailed PQC migration research report in May 2026 testing ML-DSA-44 and pqSTARK, but no PQC protection is deployed on mainnet. All production spend authorization remains ECDSA-only and consensus remains BLS-only — both quantum-vulnerable. The token's renounced ownership eliminates token-specific admin-key quantum risk, but all token value (~$344M market cap) is exposed through the L1's quantum-vulnerable transaction path. The score reflects early-stage research preparedness without any meaningful production quantum protection.
