 **Note:** Synchronizing the state will scan a big part of Ethereum blockchain, and that's a lot of work to do. It may
 take hours or even days to complete, depending on the size of zkSync blockchain.

 ## Sending exodus L1 transactions
 
 In case you have the private key for the wallet you want to perform exodus for, you may use
 [`perform_exodus`](perform_exodus) script for that matter.
 
 Otherwise, please check your wallet documentation in order to know how to execute arbitrary transactions from it.
