How far do you want to go? If you are really worried about lawsuits. You can create a shell company registered in Cayman Islands and pay to have someone run it as CEO. Extract royalities to cryto. My guess is your company will never know just use different github accounts. If they find out they may fire you but to bring a lawsuit to take the ip would be costly and rarely worth it.
