Hey everyone, quick update - the **auction contracts** for Timeboost are actually already deployed on Arbitrum One and Arbitrum Nova, which can be used for Timeboost. Should this [vote](https://www.tally.xyz/gov/arbitrum/proposal/14881197137069494959448952699217598923721993392617887469969318742509097999570?govId=eip155:42161:0xf07DeD9dC292157749B6Fd268E37DF6EA38395B9) be passed, within 5 business days, the sequencer operator will provision and enable the autonomous auctioneer to begin receiving bids and upgrade the sequencer to begin honoring the time-advantage to a given round’s express lane controller (whenever there is one). If this vote does not pass, the deployed auction contracts will simply lie dormant and remain unused. The reason why the auction contracts are deployed is because it is better to do it sooner rather than later when things are more time sensitive, and acts as a practice run so we have time to check through everything a few times. We can always deploy it again if we find an error or misconfiguration - the contracts don’t have to be used if the vote doesn’t pass. Here are the contracts that are already deployed: - ProxyAdmin: 0x5fcb496a31b7AE91e7c9078Ec662bd7A55cd3079 ([https://arbiscan.io/address/0x5fcb496a31b7ae91e7c9078ec662bd7a55cd3079#readProxyContract](https://arbiscan.io/address/0x5fcb496a31b7ae91e7c9078ec662bd7a55cd3079#readProxyContract)) - ProxyAdmin: 0xa5aBADAF73DFcf5261C7f55420418736707Dc0db ([https://nova.arbiscan.io/address/0xa5abadaf73dfcf5261c7f55420418736707dc0db#code](https://nova.arbiscan.io/address/0xa5abadaf73dfcf5261c7f55420418736707dc0db#code)) --- _[View the full topic](https://forum.arbitrum.foundation/t/aip-timeboost-nova-fee-sweep/28247)._
