Architecture

This section explains the core architectural components behind Ethera's cross-rollup coordination model.

The pages below move from the underlying coordination primitives to the bridge layer built on top of them:

• Mailbox Contracts - Cross-rollup message transport
• Shared Publisher - Coordination layer for atomic multi-rollup execution
• Two Phase Commit - Commit or abort mechanism for coordinated actions
• Execution Model - How Ethera executes cross-rollup transactions, using Rollup to Rollup as the example
• Universal Bridge - Asset-transfer and settlement layer built on top of Ethera
