marginfi oracles & Quantum Risk

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

Verdict

marginfi oracle paths are not quantum-proof. Wrong prices plus classical liquidators harm users under classical crypto assumptions.

Overview

Per-bank oracle configuration is part of lending risk—include it in quantum-adjacent inventories.

Cryptographic profile

What breaks

  • Compromise of oracles related keys for marginfi
  • Equating role separation or multisig with post-quantum algorithms
  • Untracked multi-chain deployments of the same protocol

Mitigations

  • Document privileged addresses from official docs per chain
  • Hardware/MPC for guardians, admins, and large governors
  • Return to /is-quantum-proof/marginfi for protocol context
  • Use category hubs: lending, dex, perps, stablecoins
