Adding additional networks

[JamesLawton]

We would be interested in adding additional networks for the keymap, specifically bloxberg - https://bloxberg.org. It is a sidechain of ethereum driven by PoA consensus with over 50 research organizations. Please let me know the best way to go about this.

Hey @crossoveranx I’ve recently added Matic Network to the keymap.
Please, take a look on how it was done and feel free to propose a Pull-Request!
Ideally, that would be 1 PR per new chain to keep things separated.
