Mode is an OP Stack Superchain member, which is the polite way of saying its quantum timeline is Optimism's timeline. No independent roadmap, no independent upgrade path. Whatever Ethereum and OP governance decide, Mode ships six months later.
Summary
Mode is an OP Stack Superchain L2. Standard ECDSA + Keccak-256 stack. No independent PQC activity; quantum path fully gated by Ethereum + OP Superchain. Band 1 Unaware.
What the gates say
- Hybrid: FAIL. No hybrid plan on file.
- Evidence: PASS. Sources reconstructable by third party.

The X + Y vs Z inequality
X (data shelf life): 4-8 (young L2)
Y (migration time): 10-15 (Superchain-gated)
Z10 (10% CRQC year): 2036 · Z50 (50%): 2041
Verdict: X+Y > Z (danger).
Four-scenario grid
| Scenario | Value preserved | Privacy preserved |
|---|---|---|
| quantum never | 100% | 100% |
| arrives suddenly pre migration | 5% | 10% |
| arrives slowly post migration | 80% | 70% |
| arrives slowly mid migration | 30% | 25% |

Supply chain snapshot
A chain's supply chain cannot migrate faster than its slowest dependency. Zero PQC roadmaps in any of the four categories is a structural blocker, not a lagging indicator.
Analyst notes on the scoring
Mode has no independent cryptographic sovereignty — any PQC migration is Ethereum/OP Superchain-driven. Small vendor footprint. No notable PQC signals.
