This seems to be a Cardano staking company who are trying to market themselves. I doubt they’d want to go with a sidechain since their entire business is to have people stake in the main chain.
They could go with a layer 2 network, but Cardano hasn’t implemented smart contracts or their Hydra state channels system yet.
