SUI (Sui) Quantum Risk for Holders
Verdict
SUI is only as quantum-safe as the keys and venues that control it. Sui is not quantum-proof by default. Account signatures are classical (commonly Ed25519-class); object model sophistication does not equal PQC.
Overview
SUI is the primary liquid asset associated with Sui in market-cap rankings. Holder risk is dominated by authorization keys and custody—not by slogans.
Sui uses an object-centric Move data model with modern classical signatures for account authorization. Performance and developer UX are not substitutes for post-quantum primitives.

Cryptographic profile
- Signatures: Ed25519 and other schemes supported by Sui accounts (verify current wallet defaults)
- Hash: Move/object model hashing as specified by Sui
- Public-key exposure: Object-centric accounts; authorities and pubkeys are on-chain identities.
What breaks
- Hot wallets controlling large SUI balances
- Exchange deposit operational practices
- Unmapped bridges holding wrapped value
Mitigations
- Hardware / multiparty treasury policies
- Document where balances actually live (chain, bridge, custodian)
