Is Marinade mSOL (mSOL) Quantum Proof?
Verdict
mSOL is not quantum-proof. It is a Solana LST: classical Ed25519 holder keys plus stake pool controls.
Overview
mSOL is Marinade’s liquid staking token. Quantum risk is Solana account crypto and Marinade authorities.
Cross-read Marinade protocol page.
Exposure summary: LST holders and pool program authorities. Signature surfaces: Ed25519 (Solana); Marinade stake pool authorities. Inventory holders, operators, and any bridge/issuer paths before treating mSOL as quantum-ready. Educational only.
Cryptographic profile
What breaks
- Classical signatures authorizing mSOL value under Shor-class adversaries once public keys are known
- Custodial hot wallets and exchange operational keys
- Bridges, issuers, or operator sets outside ordinary user wallets
- Protocol admin, oracle, or guardian keys
Mitigations
- Inventory every key that can move mSOL (self-custody, exchange, multisig, protocol roles)
- Name the host chain and bridge path for every balance
- Document operator/admin sets for L2s and apps
- Track ecosystem PQC research; branding is not deployment
- Use /assessment and claims methodology pages for program framing
