Polygon zkEVM Cryptography & Quantum Risk Profile

Risk: high · Confidence: high · Reviewed: 2026-07-19

Verdict

Profile view: Polygon zkEVM is not quantum-proof. It is a separate zkEVM deployment from Polygon PoS: classical EOAs plus prover/bridge keys.

This is the Wave 7e network/profile page for Polygon zkEVM (l2).

Polygon zkEVM must not be confused with Polygon PoS. User signatures are still classical EVM; ZK validity does not equal PQC wallets.

Inventory bridges specifically labeled zkEVM.

Verdict hub: /is-quantum-proof/polygon-zkevm. Asset framing: /crypto/polygon-zkevm-eth.

Classical signatures authorizing ETH value under Shor-class adversaries once public keys are known
Custodial hot wallets and exchange operational keys
Bridges, issuers, or operator sets outside ordinary user wallets
Sequencer / prover / upgrade keys on the L2 path

Inventory every key that can move ETH (self-custody, exchange, multisig, protocol roles)
Name the host chain and bridge path for every balance
Document operator/admin sets for L2s and apps
Track ecosystem PQC research; branding is not deployment
Use /assessment and claims methodology pages for program framing

Same as /is-quantum-proof/polygon?

No—PoS vs zkEVM are different deployments and key graphs.
