Q Blockchain, Lamina1, Mantle, Taiko... For a longer list, check out zealy dot io, there are a lot of projects there.
Mantle network and Taiko network are Layer 2 projects. Also, Mantle Network conducted a sale and gave 200 MNT per person. Taiko is still in the testnet phase. But the problem is since taiko is a layer 2, they will target the mainnet users. I am doing the Lamina 1(Layer 1) testnet as well. Do you have more details regarding Q Blockchain?
