Confirmations and finality

On zkSync, each transaction is one of the four stages:

• Pending. The transaction was received by the operator, but it has not been processed yet.
• Processed. The transaction is proceesed by the server and is confirmed to be included in the next block.
• Committed. The transaction state diffs were published on Ethereum.
• Finalized. The SNARK validity proof has been submitted and verified by the smart contract. After this step, the transaction is considered to be final.

The typical time for a transaction to go from Processed to Finalized is a couple of hours.

Please note that for developer convenience, we will usually treat the Processed and Committed states as a single stage called Committed since they have no difference from the UX/DexEx standpoints.
