Before you even consider downloading and executing the software, DON'T! As of now, this software should be run either in a virtual machine, or on a dedicated server with no critical data on it. Be sure you read the section about security. Be sure you do not run the software where a malicious attacker could locally (on machine, or local network) cause harm by running the software.

Moreover: (mini EULA)

  • By downloading and executing the software, you agree to have been granted the non-exclusive right to run the software unaltered.
  • If you tamper with the software, the software may cease to work, remove itself from disk or eat your cat. You have been warned!
  • The software contains code to execute code sent by the LBC-server remotely. This could be used - by us - for all sorts of shady things. We do however guarantee, that the LBC will only touch files it needs for its operation (= BTC address generation) and nothing else on your system.
Summary: If you do not trust the LBC server and the people behind it - do not run the software!
