XTZ (Tezos) Quantum Risk for Holders
Verdict
XTZ is only as quantum-safe as controlling keys and venues. Tezos is not quantum-proof. Account and baker keys use classical public-key schemes; on-chain governance does not equal PQC deployment for all wallets.
Overview
XTZ is the liquid ticker framing for Tezos in Wave 7e. Holder risk is dominated by authorization keys and venues—not slogans.
Tezos emphasizes formal upgradeability and multiple account crypto options. All common options today are classical from a CRQC perspective.

Cryptographic profile
- Signatures: tz1/tz2/tz3 account signature schemes (Ed25519/secp256k1/P-256 class options—verify), Baker consensus keys
- Hash: Tezos operation hashing
- Public-key exposure: Accounts public; multiple address types mean mixed classical curves.
What breaks
- Hot wallets controlling large XTZ balances
- Unmapped bridges, issuers, or L2 operators
- Wrong host-chain assumption for multi-chain assets
Mitigations
- Hardware / multiparty treasury policies
- Document chain, bridge, and custodian for every balance
