MANTA PACIFIC · rollup-L2 · QRI 11 · BAND 1 Unaware Hybrid FAIL · Stage 0 · Washing 1x

Manta Pacific calls itself modular, which is another way of saying it depends on two other chains to survive. Polygon zkEVM plus Celestia DA means any PQC migration has to happen twice, in two governance forums that have never had to agree on crypto.

Summary

Manta Pacific is a modular L2 combining Polygon zkEVM + Celestia DA, mainnet Sept 2023. Standard pairing-based PLONK + Ed25519 DA stack, all Shor-breakable. No PQC activity. Migration is structurally complex due to Polygon zkEVM + Celestia dual dependencies. Band 1 Unaware.

The X + Y vs Z inequality

X (data shelf life): 4-8 (young L2)

Y (migration time): 10-15 (dual-layer complexity — Polygon + Celestia)

Z10 (10% CRQC year): 2036 · Z50 (50%): 2041

Verdict: X+Y > Z (danger).

Supply chain snapshot

wallet MetaMask · Manta Wallet · Rabby 0 PQC roadmaps

bridge Manta Native Bridge · LayerZero · Celer cBridge 0 PQC roadmaps

custodian Fireblocks · BitGo · Coinbase Custody 0 PQC roadmaps

rpc_hsm Manta RPC · Ankr · 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

Dual-layer architecture (settlement + DA) doubles PQC coordination surface. Manta Atlantic (separate zk-privacy chain on Polkadot) would score differently but is out of scope here.
