Our Relationship with Ethereum & EthereumJS
We would like to mention that we are not in any way affiliated with the Ethereum Foundation. However, we love the work they do and work with them often to make Ethereum great! Our aim is to support the Ethereum ecosystem with a policy of diversity, modularity, simplicity, transparency, clarity, optimization and extensibility.
