What's your favorite Chain currently? Why?

There are an ever-growing amount of blockchains, so it seems. Which are your current favorites? Why? What cool projects are happening on them? New dApps?

We currently have our liquidity pool on Mainnet.
We do some nft/wearable minting on Polygon and
we have a few embassies big in the xDai game.

We also have some Cryptoskateboards made on Near Protocol.

Multi chain seems to be the way, eh?
