The Initia L1 is a custom-built Layer 1 blockchain that serves as the central coordination layer for all Interwoven Rollups. The L1 is built on the Cosmos SDK and is responsible for:
Security: Rollups leverage Initia L1’s security for various purposes including token bridging, state commitments, and fraud proofs
Liquidity: The InitiaDEX on L1 acts as a central liquidity hub for the ecosystem, providing a seamless experience for token liquidity and cross-rollup bridging and swaps
Interoperability: L1 functions as a central hub and router for rollups, enabling seamless communication and state transitions both between rollups and with the broader blockchain ecosystem
