A little suggestion regarding “contracts” (as the devs are working on that atm):
please do not have just “goods vs money”-contracts, but also “goods vs goods”.
Example:
manufactoring MHL in your WEL, but you need Iodine (and others) as input…
-> have a contract "delivering 4 MHL after 4 days after receiving 4 HE, 4 FE and 4 I and 2.000 ICA"
So a business partner can deliver the required ressources and pay someone to do manufatoring for him.
