The project is described to be a new DeFi primitive built by GHOULS and designed to encourage alignment, growth, and collaboration between fair-launch projects.
Moonbase is described to be kind of like an index fund or Balancer pool, users deposit their $BASED into Moonbase and in return, they get mbBASED. mbBASED is a standard ERC-20 token that represents their share of TVL in the Moonbase. All of the complexities of rebasing are handled within the Moonbase, so this provides a new layer of composability for the $BASED token itself.
