Optimism
Analyze OP Mainnet transactions with Skylens — decode execution traces, follow token flows, and debug contracts on the original OP Stack rollup.

OP Mainnet (Optimism) is the reference deployment of the OP Stack, the rollup framework that also powers Base, World Chain, and Unichain. Its predeploy architecture — system contracts at fixed 0x42... addresses, including the OP token itself — gives transactions a distinctive shape that generic explorers gloss over.
Skylens traces OP Mainnet transactions through both application contracts and OP Stack predeploys, and its familiarity with the OP Stack pays off across every Superchain network you investigate: learn the pattern once, reuse it on Base, World Chain, and Unichain.
