 For any cross-chain token transfer to be finalized such that the token may be withdrawn on the underlying L1, a valid pessimistic proof must be generated. Each chain connected to the AggLayer is required to provide some of the inputs necessary for building a valid pessimistic proof.

-=======
 Each chain maintains a data structure called a **Local Exit Tree**, which contains only the messages and token transfers originating from it. In the unified bridge, Ethereum holds a **Global Exit Root**, which represents a tree containing all of the Local Exit Roots of chains integrated with the AggLayer.
