Synchronous smart contract execution across Ethereum rollups without bridging mechanisms will increase usability of assets in EVM environments and lead to greater activity in the Ethereum ecosystem.

"EEZ could allow smart contracts on different participating networks to interact within the same transaction. Better composability can translate into smoother execution paths for complex DeFi operations—potentially reducing the friction that users face when assets must move across ecosystems before a transaction can complete."

"The EEZ will have the benefit of reducing the need for bridges (where hacks tend to occur) and increasing the usability of assets in EVM chains. These factors are likely to lead to greater activity in the Ethereum ecosystem."
