Hart Lambur is the Co-Founder of Risk Labs, the foundation behind the Across and UMA Protocols. Across is a next-generation bridge designed around the “Intents” model, delivering fast interoperability to unify Ethereum’s fragmented landscape. UMA is a pioneering optimistic oracle, empowering onchain verification of complex, real-world data for prediction markets and other decentralized applications.

Ethereum has scaled with a diverse ecosystem of L2s—but this created a new challenge: how can this fragmented landscape of potentially millions of rollups feel like a **unified Ethereum**? In this talk, I’ll discuss how intent-based architectures—and new standards like ERC-7683—can help unify Ethereum while maintaining the benefits of Ethereum’s rollup centric architecture.

Keynote: Unifying Ethereum Through Intents and ERC-7683

This panel will dig into the delicate balance of Ethereum's rollup-centric future. We'll talk about the "frenemy" dynamic between competing L2 ecosystems, and how this can lead to a fragmented user experience. We'll strategize on ways to maintain diversity while making interoperability easy for users—including a discussion on the pros/cons of supporting standards like ERC-7683. Can we get the best of both worlds: the innovation and diversity of many L2s, with the UX of a unified Ethereum?
