Yearn governance & Quantum Risk
Verdict
Yearn governance is not quantum-proof. YFI political control uses classical signatures over vault strategies.
Overview
Vault strategies can move large TVL; governance that can change strategies is a quantum-relevant key graph.
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: YFI voters and yTeams/executors as deployed
- Hosts/context: YFI governance
What breaks
- Compromise of governance 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
