At this time, there are no boosts available on sidechains. This is because the technology is still in its early stages of development and has yet to be implemented through the user interface. However, developers are working to make this a reality in the near future. With the help of smart contracts, developers are aiming to create a system of incentives that will make sidechains more attractive to users. This could include rewards for users who use sidechains, as well as other incentives that would make sidechains more attractive to a wider range of users. Once these incentives are in place, it is likely that boosts will become available on sidechains as well.
