Optimism has teamed up with Flashbots to introduce advanced transaction sorting capabilities to the Superchain, aiming to improve performance and customization of the OP Stack chain. This partnership will leverage technology from the Ethereum Sorting Pipeline team to offer fast, configurable, and verifiable transaction sorting. As of August 2025, Superchain handles over 60% of Ethereum's Layer 2 network transactions. The collaboration promises lower latency, increased fairness, and enhanced programmability, while reducing costs and speeding up market launches. Flashbots' technology, which has achieved 200 millisecond confirmation times on other chains, will be gradually implemented on the OP mainnet and beyond.
