In today’s landscape, rollups have emerged as essential infrastructure to scale Ethereum. But while they’ve gained traction as a scalability solution, rollups face a tough economic reality: transaction fees alone often fail to cover operational costs, leaving little room for growth. This led us to asking a fundamental question: how can rollups become sustainable revenue models that foster growth, security, and profit? 

 

As we explored solutions, it became clear that MEV could be transformed from a challenge into an opportunity. While MEV has traditionally raised concerns about user risks, we saw potential for a better approach with Radius—one that could create sustainable revenue while protecting user interests.

 

WHY WE INVEST IN RADIUS

 

Radius is building economic infrastructure that helps rollups unlock new revenue through MEV. This approach has made Radius the only solution in the market today that aligns profit potential with user security, a combination that immediately stood out to us. We view MEV as more than a simple revenue stream; it’s a powerful tool to drive growth and reinvestment within the ecosystem. 

 

Through Lighthouse, a decentralized network that connects rollups with searchers to capture MEV opportunities, and Secure Block Building (SBB), rollups are able to harness this potential without compromising their independence or users’ trust. By transforming MEV into an actionable, sustainable revenue source, Radius not only provides financial stability for rollups but also reshapes the way economic value circulates across the Ethereum ecosystem.
