# Rollup Rollups are L2 chains that facilitate computations outside the main blockchain. The transfer of transaction details takes place after a certain interval, hence offering the necessary backup for maintaining records. Besides, rollups can manage transactions with minimal interference to the main chain. Therefore, they can ensure transactions are processed faster and at minimal costs. Optimistic and zero-knowledge are the common types of rollups. --- # 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.
