The Ethereum Economic Zone has announced three new demonstrations involving CoW Swap, Safe, and post-quantum signatures, showing how applications on Ethereum rollups can interact directly with the mainnet within a single transaction. Ethereum Economic Zone announced three technical demonstrations at Devcon involving CoW Swap, Safe and post quantum signatures, with transactions coordinated between Ethereum mainnet and rollups. CoW Swap demonstrated how users on a rollup could execute trades using Ethereum mainnet liquidity and receive tokens within the same transaction without a separate bridge or additional signature.
