 - **A special “express lane”** which allows valid transactions to be sequenced as soon as the sequencer receives them for a given round.
 - **An off-chain auction** to determine the controller of the express lane for a given round. This auction is managed by an <a data-quicklook-from='autonomous-auctioneer'>autonomous auctioneer</a>.
-- **An <a data-quicklook-from='auction-contract'>auction contract</a>**deployed on the target chain to serve as the canonical source of truth for the auction results and handling of auction proceeds.

 To start, the default duration of a round is 60 seconds. Transactions not in the express lane will be subject to a default 200-millisecond artificial delay to their arrival timestamp before their transaction is sequenced, which means that some non-express lane transactions may get delayed to the next block. It’s important to note that the default Arbitrum block time will remain at 250 milliseconds (which can be adjusted to 100 milliseconds if desired). Let’s dive into how each of these components works.
