zkSync Era C-

  • Validity (ZK) proofs
  • Native account abstraction
  • Large ecosystem & ZK tech
  • L2BEAT Stage 0 (operator-dependent exits)
  • Centralized sequencer & prover

OP Mainnet C+

  • L2BEAT Stage 1
  • Concrete shared-sequencing roadmap
  • Superchain network effects
  • Centralized sequencer today
  • Foundation influence

Bottom line

Good cryptography, but still Stage 0 — the weakest exit guarantees among major L2s here. Stage 1 with the clearest path to decentralized sequencing.
