# POL (ex-MATIC) (POL) Quantum Readiness Report > POL (ex-MATIC) has a QRI score of 10/100 and is assessed at Stage 1 (Quantum Risk Assessed) with medium evidence confidence. Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: Native gas/staking token on Polygon PoS and ERC-20 token on Ethereum L1. Evaluation covers Polygon PoS production consensus, spend authorization, bridge paths, and L1 token dependency. Polygon zkEVM sunset (2026-07-01) confirmed and excluded from primary production scope. AggLayer uses SP1 zkVM with Plonky3 proving system.. POL (ex-MATIC) is the native gas and staking token of Polygon PoS, an Ethereum L2 scaling network. As of June 2026, all production cryptographic mechanisms on Polygon PoS rely entirely on quantum-vulnerable classical cryptography: secp256k1 ECDSA for spend authorization (Bor block production, Heimdall account authentication) and BLS signatures for Heimdall checkpoint consensus. POL also exists as a standard ERC-20 token on Ethereum L1, inheriting Ethereum's full ECDSA vulnerability for L1 transfers and staking. The Polygon zkEVM — which had a partially PQ-safe STARK proof foundation — is confirmed to be sunset on July 1, 2026. AggLayer uses SP1 zkVM with Plonky3 SNARK-based proving with pairing-dependent cryptography. ERC-4337 account abstraction provides an optional theoretical path to PQ signatures via smart-contract wallets, but no Polygon-provided PQ implementation, tooling, or migration guidance exists. Polygon Labs has published no quantum risk assessment, cryptographic inventory, PQ roadmap, migration plan, or quantum-specific incident-response process. The Least Authority audit (2023) predates Heimdall v2 and contains no quantum scope. Score of 10/100 reflects Stage 1 (Quantum Risk Assessed) with no meaningful production protection, capped by the absence of any PQ spend authorization, complete ECC/BLS dependence across all consensus and transaction layers, unrestricted two-way bridge to quantum-vulnerable Ethereum L1, and material long-exposure value-at-risk with no migration path. ## Core resources - [POL (ex-MATIC) QRI report](https://qrindex.org/projects/polygon-ecosystem-token/): Human-readable assessment with score, stage, evidence, blockers, risks, and assurance notes. - [POL (ex-MATIC) structured report data](https://qrindex.org/projects/polygon-ecosystem-token/report.json): Complete report as JSON for deterministic machine processing. - [QRI methodology](https://qrindex.org/methodology/): Scoring model, evidence handling, readiness stages, confidence, assurance, and report status. - [All QRI project reports](https://qrindex.org/llms.txt): Score-ranked index of every published project assessment. - [POL (ex-MATIC) official website](https://polygon.technology/): Project-maintained website. - [POL (ex-MATIC) source repository 1](https://github.com/0xpolygon): Project source code referenced by QRI. ## Evidence sources - [Evidence source 1](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 2](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 3](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 4](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 5](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 6](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 7](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 8](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 9](): Public source cited by the POL (ex-MATIC) QRI assessment. - [Evidence source 10](): Public source cited by the POL (ex-MATIC) QRI assessment.
