## Description

Curious about simplifying cross-L2 payments and multi-chain user experiences? Join DC Posch, co-founder of a DAO, as he unveils intent addresses—a new Ethereum primitive that lets users accomplish arbitrary actions across different networks with a single transfer. Discover how Create2, escrow contracts, and minimal bridging steps eliminate confusing flows, reduce counterparty risk, and streamline DeFi interactions. Learn how to enable fast finish on cross-chain transactions, explore real-world demos (like prediction markets and hardware wallet orders), and see how these ideas could become a future ERC for broader adoption.

Topics Covered:
• Chain fragmentation & the push for a “one Ethereum” experience
• Universal accounts, 4337, and the inspiration behind intent addresses
• Bridging with CCTP and adding escrow for faster settlements
• Real-world demos on Base, Optimism, and more
• Bonus: Gasless transactions, permit flows, and self-destruct for ephemeral contracts
• Stay tuned to discover how these concepts reshape UX for multi-chain payments, enabling an interoperable future with fewer pop-ups, less friction, and maximum flexibility.
