Soneium Cryptography & Quantum Risk Profile

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

Verdict

Profile view: Soneium is not quantum-proof. Sony-associated L2 branding does not change classical EVM signature risk for users.

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

Soneium is an OP-Stack L2 aimed at entertainment and consumer crypto. Authorization crypto remains secp256k1 EOAs in the common model.

Inventory creator treasuries, bridges, and marketplace approvals.

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

Signatures: ECDSA-secp256k1 (EVM EOAs), OP-Stack operator keys as deployed
Hash: Keccak-256
Public-key exposure: Enterprise/consumer L2; EOAs and bridges public-key based.

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

Corporate L2 = PQC?

Corporate ops may improve process; algorithms must still migrate.
