Optimism Partners With Flashbots for 200ms Confirmations in Superchain
Optimism has partnered with Flashbots to enhance sequencing infrastructure for the Layer-2 Superchain, which includes over 30 partners such as Base and Unichain.
- The partnership aims to introduce configurable, verifiable sequencing features across the Superchain network.
- These features are expected to reduce user latency, improve execution fairness, scalability, and programmability.
- As of August 2025, the Superchain accounted for over 60% of all Ethereum L2 transaction activity.
- More than 90% of Ethereum blocks utilize MEV‑Boost, a solution from Flashbots.
Flashbots Technology Impact
- Flashbots’ technology has achieved 200ms confirmation times for users on Base and Unichain.
- A full rollout of these features across the Superchain is anticipated in the coming months.
- The partnership will introduce "Rollup-Boost" and cryptographically-backed transaction services ("TEEs") for developers.
In early August, Unichain became the first Ethereum L2 to implement sub-second latency and verified ordering using Flashbots' technology.
