Euler oracles & Quantum Risk
Verdict
Euler oracle dependencies are not quantum-proof. Wrong prices plus classical liquidator keys create classical and future CRQC-relevant integrity risk.
Overview
Isolated markets still need honest prices. Treat each market’s oracle configuration as a crypto inventory row.
Cryptographic profile
- Signatures: Host-chain account signatures for role holders (typically classical ECDSA/Ed25519), Multisig/module keys as deployed
- Hash: Host-chain dependent
- Public-key exposure: Oracle adapters and underlying reporters
- Hosts/context: Per-asset price sources
What breaks
- Compromise of oracles related keys for Euler
- 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/euler for protocol context
- Use category hubs: lending, dex, perps, stablecoins
