Optimism collaborates with Flashbots to enhance sequencing capabilities on OP Stack: The new benchmark for layer‑two performance
The Superchain, encompassing networks such as Base, Unichain, World Chain, Ink, and Soneium, dominates over 60% of Ethereum layer 2 traffic by August 2025.
Partnering with Flashbots—builders behind MEV‑Boost, BuilderNet, and Flashblocks—promises to elevate the OP Stack’s performance and flexibility to unprecedented heights.
Under this alliance, OP Stack developers will tap into a battle‑tested toolkit of sequencing options honed on Ethereum and tuned for layer 2, such as 200‑millisecond confirmations via Flashblocks—already live on Base and Unichain and slated for rollout to OP Mainnet and other Superchain chains.
Additional capabilities feature programmable block construction, verifiable fairness through secure enclaves, ethical MEV capture, and stronger resilience against spam.
These tools empower builders to fine‑tune latency, fairness, and scalability for tailored use cases, keep sequencer revenue inside their ecosystems, and quicken time‑to‑market using battle‑tested components.
“With Flashbots as a crucial technology ally, we’re propelling the OP Stack’s fast, affordable, and customizable sequencing roadmap,” explained Sam McIngvale, Head of Product at OP Labs. “Our overarching goal is to give builders the liberty to craft chains on their own terms, supported by open, adaptable, and proven infrastructure.”
The collaboration will prioritize scaling Flashblocks throughout the Superchain and offering advanced sequencing options as configurable features.
