Last updated 1 month ago

We’re preparing a detailed technical overview of Lighthouse to help you understand its architecture and cross-rollup coordination capabilities. In the meantime, discover how Lighthouse accelerates rollup revenue growth and fosters economic unity across Ethereum, or connect with our team to learn more about integrating with Lighthouse. .

Introducing Lighthouse

Lighthouse is a network that connects rollups and searchers to capture MEV across Ethereum. Building on , it introduces decentralized, competitive auctions to optimize rollup profits and efficiency.

Currently, MEV is fragmented and locked within individual rollups. Lighthouse unifies these systems, creating a shared pool of MEV opportunities for collective revenue. This unified network gives searchers access to a broader market, and as more rollups participate, the system's scale increases—enhancing Ethereum's economic efficiency.


Why Lighthouse?

Lighthouse broadens MEV access for rollups and searchers, delivering these key benefits:

  • Expanded MEV Market: Enables cross-rollup arbitrage and L1-L2 arbitrage, alongside CEX-DEX arbitrage, atomic arbitrage, and liquidations.

  • Higher Revenue: Increases MEV opportunities to attract more searchers while auction mechanisms minimize spam, resulting in higher bids and greater rollup profits.

  • Aligned Incentives: Distributes MEV profits between rollups and searchers through a transparent and competitive system.


How It Works

Lighthouse extends SBB by coordinating MEV auctions across rollups. Here’s the process:

  1. Searchers: Identify MEV opportunities like arbitrage and liquidations across multiple rollups, then submit transaction bundles to Lighthouse's blockspace for auctions.

  2. Lighthouse Network: Conducts auctions where the highest bidders win execution rights for their transaction bundles across rollups.

  3. Rollups: Execute the winning bundles and collect MEV revenue alongside regular transaction fees.

Lighthouse creates a scalable MEV market where searchers access broader opportunities and rollups increase earnings without added complexity. This integration benefits Ethereum by creating a more efficient, interconnected economy—setting the foundation for a sustainable ecosystem.
