Is Spark (SPK) Quantum Proof?
Verdict
Spark is not quantum-proof. Ethereum classical signatures authorize users; Sky-aligned modules add governance/admin key risk.
Overview
Spark provides lending/savings products in the Sky ecosystem. Quantum risk is EOA + protocol admin graphs.
Cross-read Aave/Sky for related patterns.
Exposure summary: Lending/savings products; protocol admins and stablecoin links. Signature surfaces: ECDSA-secp256k1; Sky/Maker-related module admins as integrated. Inventory holders, operators, and any bridge/issuer paths before treating SPK as quantum-ready. Educational only.
Cryptographic profile
What breaks
- Classical signatures authorizing SPK 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
- Protocol admin, oracle, or guardian keys
Mitigations
- Inventory every key that can move SPK (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
