Join the Constellation Ecosystem
With the Hypergraph serving as its foundational layer, Constellation empowers projects to create their own metagraph L1s—application-specific blockchains that can be built on any other chain.
Stardust Collective supports the Constellation ecosystem and offers grants for projects to build metagraphs.
Take a look at the Hackathon-winning projects below for inspiration.
