Universal Message Passing Interface

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.
