# Core Infrastructure Eclipse’s modular infrastructure provides execution scalability, verifiability, and user sovereignty. The system is structured around three foundational components: * **Eclipse Canonical Bridge**: Provides secure withdrawal finality and settlement on Ethereum. * **Eclipse L1 Gateway**: Ethereum L1 smart contract that stores batches posted by the L2 that contain pointers to Celestia blobs and state commitments. * **Eclipse Celestia Publisher**: Ensures scalable data availability by batching and posting Eclipse block data to Celestia. Together, these components uphold Eclipse’s rollup guarantees while offering flexibility for future upgrades. *** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
