@sponnet your call on what you think the right names should be. The thinking is that we remove the "tech" part. Perhaps something like :
tech-dapp -> swissmem-dapp-api
tech-dapp-api --> swissmem-dapp
tech-token --> cstk-token

Is there ever a good time to do this kind of housekeeping!? No, right?
@sponnet Can we set a soft target on when to aim to do this?
