Hart Lambur, co-founder of Across Protocol and UMA, discusses Across’s mission to enable fast, low-cost asset transfers between Ethereum layer twos, with a focus on creating a seamless user experience. He explains how the protocol’s “intent architecture” leverages third-party solvers to improve cross-chain interactions, offering a cohesive way for users to transfer assets and execute transactions across different Ethereum networks. Lambur also emphasizes the importance of Ethereum’s upcoming account abstraction upgrades in achieving a unified ecosystem, allowing actions on any Ethereum chain from a single wallet. He envisions a future by 2025 where Ethereum feels like a unified network, improving user experience significantly.
