Spark Cryptography & Quantum Risk Profile

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

Verdict

Profile view: Spark is not quantum-proof. Ethereum classical signatures authorize users; Sky-aligned modules add governance/admin key risk.

Overview

This is the Wave 7e network/profile page for Spark (app).

Spark provides lending/savings products in the Sky ecosystem. Quantum risk is EOA + protocol admin graphs.

Cross-read Aave/Sky for related patterns.

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
