Yearn admin keys & Quantum Risk
Verdict
Yearn admin and strategist keys are not quantum-proof. Strategy permissions are classical high-value surfaces.
Overview
Yearn-style vaults separate depositors from strategists—both need inventory; algorithms remain classical.
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: Vault managers, strategists, emergency admins
- Hosts/context: Vault management roles
What breaks
- Compromise of admin keys related keys for Yearn
- 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/yearn for protocol context
- Use category hubs: lending, dex, perps, stablecoins
