# Mantle (MNT) Quantum Readiness Report

> Mantle has a QRI score of 4/100 and is assessed at Stage 0 (Unassessed / No Evidence) with medium evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: Native asset (MNT), L2 execution layer, bridge contracts, and data availability dependencies.

Mantle is an Ethereum L2 ZK Validity Rollup with ~$1.7B in Total Value Secured. Every quantum-critical cryptographic layer in the current production system is quantum-vulnerable: user transaction signatures are ECDSA secp256k1 (and secp256r1 via RIP-7212), L1 proof verification uses Groth16/PLONK over BN254 pairing-based SNARKs, and data availability depends on Ethereum KZG commitments over BLS12-381. Mantle has published zero quantum risk assessment, cryptographic inventory, migration roadmap, or any acknowledgment of the quantum threat. The sole point earned in Migration Status reflects the minimum <25% coverage score for unprotected value-at-risk. The 3 points in Algorithm & Implementation Assurance reflect open-source, reproducible code. Score: 4/100 (Stage Cap: 5, Readiness & Risk Cap: 10, Factor Score: 4).
