MODE · rollup-L2 · QRI 10 · BAND 1 Unaware Hybrid FAIL · Stage 0 · Washing 1x

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.

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).

arrives slowly post migration	80%	70%
arrives slowly mid migration	30%	25%

Supply chain snapshot

wallet MetaMask · Rabby · Rainbow 0 PQC roadmaps

bridge Mode Native Bridge · Superchain interop · LayerZero 0 PQC roadmaps

custodian Fireblocks · BitGo · Coinbase Custody 0 PQC roadmaps

rpc_hsm Mode RPC · Alchemy · QuickNode 0 PQC roadmaps

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.
