Optimism has one of the strongest governance machines on the list. Bicameral houses, a Security Council, a 2022 bridge patch shipped before exploit. Zero of that coordination muscle has been turned toward PQC. The capacity exists. The decision to use it does not.
Summary
Optimism (rollup-L2) is Band 2 (Acknowledged). ECDSA secp256k1 inherited from Ethereum; BN254 used for L1 precompiles — both Shor-break. OP Stack's Security Council provides governance speed, but no PQC roadmap. RetroPGF could fund PQC public-goods work but none funded to date. Superchain (Base, Soneium) inherits same exposure.

The X + Y vs Z inequality
X (data shelf life): 5-10
Y (migration time): 7-12 (L1-dependent)
Z10 (10% CRQC year): 2036 · Z50 (50%): 2041
Verdict: X+Y > Z (danger).

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
Governance Dim 7 (62) is relatively strong; pulls down by Dim 5/6 voids. Rollup can ship PQC faster than L1 in principle — opportunity for first-mover L2 with PQC proofs.
