What is Radius?

Radius builds open market infrastructure to support truly open and scalable economic activity on Ethereum.

Our infrastructure connects rollups and searchers into a single collaborative network - enabling new ways to access opportunities and capture value. With protocols like Secure Block Building (SBB) and Lighthouse, the ecosystem can run competitive auctions, execute advanced arbitrage, and unlock revenue in ways that benefit the whole ecosystem.

By breaking down silos across rollups, exchanges (CEX/DEX), and isolated markets, Radius makes markets more open, incentive-aligned, and efficient in how value is shared across Ethereum.

Radius brings three core advantages to Ethereum:

  • Transparency at every layer – Clear visibility to how value flows, from transaction ordering to final market outcomes.

  • Collaborative markets – Open coordination across participants, where opportunities are broadly accessible.

  • Institutional readiness – Predictable, compliance-friendly systems that position Ethereum as a credible foundation for global-scale markets.
