Optimism is teaming up with Flashbots to revamp how transactions get processed across its OP Stack ecosystem, aiming to make some of Ethereum’s most popular layer-2 networks faster and more customizable.
The partnership centers on sequencing, the behind-the-scenes process that determines how quickly a transaction confirms, which trades are prioritized, and how much users ultimately pay. Optimism says Flashbots’ infrastructure, which is already responsible for building more than 90% of Ethereum’s blocks, will now bring near-instant confirmations and user-friendly transaction ordering to every chain in the so-called Superchain.
This matters because the OP Stack underpins more than 60% of all Ethereum layer 2 activity, the Optimism team claims, including some of the most well-known layer-2 chains like Base, Unichain, World Chain, Ink and Soneium. Until now, advanced sequencing features such as ultra-fast settlement, frontrunning protection and custom compliance rules were only avail
