Castle (after today) is a masternode coin that has has borne into the world two main projects: Axioms and Cryptoincubator.

Axioms is an automated airdrop platform, that will operate with an erc20 utility token (snapshot to come off the Castle masternode chain) --->
https://axioms.app/ and the platform--> https://platform.axioms.app/

Cryptoincubator is a project that helps entrepreneurs wishing to get into crypto, but not having the resources to create their own blockchain, do exactly that. And get the benefit of having a pre-existing community (a kick start to getting a business going). These projects, for now, shall snapshot off the Castle chain when created --> https://cryptoincubator.io/
