Cross-Rollup Interoperability

Definition

Cross-Rollup Interoperability denotes the capacity for different layer-2 rollup solutions to communicate and transact with each other seamlessly. This allows assets and data to transfer between separate rollup environments without needing to return to the main layer-1 blockchain. Achieving this functionality is crucial for creating a cohesive and efficient multi-rollup ecosystem. It addresses the fragmentation of liquidity and user activity across various scaling solutions.
