Optimism Partners With Flashbots To Enhance Sequencing Across All OP Stack Chains
Layer 2 scaling answer constructed on Ethereum, Optimism introduced a partnership with Flashbots, a analysis and improvement group centered on mitigating the destructive results of Maximal Extractable Worth (MEV). The collaboration goals to deliver quick, configurable, and verifiable sequencing to the Superchain, leveraging the workforce that developed Ethereum’s sequencing pipeline. For builders constructing on the OP Stack, this partnership presents enhanced differentiation by sequencer innovation, enabling them to seize extra worth and deploy options extra effectively and cost-effectively.
As of August 2025, the Superchain accounts for over 60% of Ethereum Layer 2 transaction exercise, with networks resembling Base, Unichain, World Chain, Ink, and Soneium using the OP Stack. The addition of Flashbots’ experience additional enhances the OP Stack’s efficiency and suppleness. Flashbots, acknowledged as a pacesetter in sequencing infrastructure since 2020, has pioneered initiatives together with mev-boost, BuilderNet, and Flashblocks.
On Ethereum Layer 1, Flashbots’ improvements have reshaped block manufacturing at scale, with greater than 90% of Ethereum blocks now constructed by MEV‑Enhance, making a clear, aggressive blockspace market dealing with billions of {dollars} day by day and lowering dangerous frontrunning. BuilderNet, a decentralized block-building community working on Trusted Execution Environments (TEEs), at the moment produces 45% of Ethereum blocks whereas sharing MEV with the group.
Past Layer 1, Flashbots has launched main sequencing enhancements to OP Stack chains. Flashblocks delivers 200ms affirmation instances and is reside on Base and Unichain, with OP Mainnet integration forthcoming. Rollup-Enhance gives a modular, open interface for third-party builders, powering Unichain’s Verifiable Precedence Ordering and World Chain’s Precedence Blockspace for People. Verifiable block constructing, utilizing TEEs pioneered by Flashbots, provides customers cryptographically verifiable ensures relating to transaction processing, growing transparency throughout the market.
This know-how is now accessible to all builders on the OP Stack, providing the Superchain higher scalability, customization, and programmability than different options at the moment out there.
Optimism And Flashbots Introduce Superior Sequencing Instruments And Flashblocks Deployment For OP Stack Builders
Optimism and Flashbots are elevating sequencing to a core functionality that each one builders can leverage. Preliminary options will embrace absolutely programmable block constructing, enabling purposes from on the spot cost settlements to encrypted transaction ordering for delicate trades and compliance necessities, all configurable with minimal code. The system additionally permits accountable seize of MEV worth by intelligently auctioning blockspace in order that earnings stay throughout the ecosystem, supporting development or lowering prices for customers. Moreover, it enhances scalability by limiting dangerous on-chain exercise, enhancing effectivity and decreasing charges for normal individuals.
These instruments present chains with the flexibility to innovate in person expertise and monetize blockspace responsibly whereas sustaining a aggressive edge. Flashblocks will quickly be deployed to OP Mainnet and different chains, establishing near-instant 200ms block instances throughout the Superchain. Advantages for OP Stack builders can be launched progressively over the approaching months.
Optimism is constructed to allow sooner and extra cost-efficient transactions whereas preserving the safety requirements of the Ethereum mainnet. It achieves this by optimistic rollups, which bundle transactions off-chain and submit them to Ethereum on a periodic foundation, assuming their validity except disputed by fraud proofs inside a delegated timeframe.
Not too long ago, the community announced the discharge of Superchain Improve 16, which implements the required good contract adjustments to help the longer term activation of Superchain interoperability, although inter-chain performance isn’t but energetic.
