Ether.fi governance & Quantum Risk
Verdict
Ether.fi governance is not quantum-proof. Token governance uses classical host-chain signatures.
Overview
Separate weETH holder risk from ETHFI governance power in inventories.
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: ETHFI voters and treasury
- Hosts/context: ETHFI governance as deployed
What breaks
- Compromise of governance related keys for Ether.fi
- 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/etherfi for protocol context
- Use category hubs: lending, dex, perps, stablecoins
