Ethereum Economic Zone Demo Combines Balance Limits From Multiple Safe Accounts
The demonstration also synchronously verified owner changes for Layer 1 and Layer 2 accounts in one transaction.

Ethereum Economic Zone (EEZ) demonstrated a Safe payment that combined balance limits from multiple Safe accounts, showing how its framework can coordinate actions across Ethereum and rollups within one transaction.
The Safe demonstration also synchronously verified owner changes for Layer 1 and Layer 2 accounts. EEZ’s approach lets a contract use a result from another network in the same transaction.
Rollup X is an EEZ development network that launched as a public testnet at Devcon in Mumbai on Nov. 4.
