Etherlinker for UE4 - interact with Ethereum blockchain from Unreal Engine 4

  1. I guess it’s not hard to drop or ignore other functionality - just read comments and remove all that you don’t need, or leave everything as is in case if in future you will need it. You can use this project in a UE4 client/server multiplayer project or singleplayer project (in this case, the integration server will be installed on end-user PC). Java-based integration server doing all job to interact with Ethereum network and UE4 only sends requests to integration server (so it’s possible to use this project with other game engines if you write request wrapper). Read more in the documentation.

  2. You can via Geth/Parity.
