The brief

Analyst view
  • The OP Stack powers production chains including World Chain, Unichain, Zora, Ink, Mode and many others.
  • Base exited in Feb 2026 to operate independently, reducing OP Labs' sequencer revenue.
  • Interoperability (Interop) was approved in September 2026, enabling atomic cross-chain transactions on the Superchain.

Technical approach

As reported
OP Stack

Modular rollup framework

Developers assemble rollup chains from pluggable components: execution, settlement, sequencing, and data availability.

Superchain

Multi-chain governance

Members run the same OP Stack version and are governed by the Optimism Collective, enabling coordinated upgrades.

Interop

Atomic cross-chain transactions

Transactions atomically change state on multiple chains. Both succeed or both fail; no bridges needed.

Data Availability

Flexible DA layers

OP Stack chains can prove their data on Ethereum, Celestia, or other DA layers. Not all chains must use Ethereum L1, reducing costs.
