marginfi admin keys & Quantum Risk
Verdict
marginfi admin keys are not quantum-proof. Bank configuration authorities are classical high-value Solana keys.
Overview
Lending groups can be configured by admins—users should know who can change risk limits.
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: Group admin and bank configuration keys
- Hosts/context: Solana marginfi banks
What breaks
- Compromise of admin keys 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
