Rollup Interoperability

Definition ∞ Rollup interoperability refers to the ability of different rollup solutions, which are layer-2 scaling mechanisms, to communicate and exchange assets or data with each other or with the base layer blockchain. This functionality enables a more connected and efficient ecosystem across various scaling environments. It is essential for a unified user experience.
Context ∞ Achieving robust rollup interoperability is a significant technical challenge and a key area of development for the Ethereum ecosystem and other modular blockchains. Current efforts concentrate on designing secure and efficient bridges, shared sequencing mechanisms, and standardized communication protocols to facilitate seamless interaction between disparate rollups.
