We free minted to everyone who signed up for WL last year. Only 30% filled. The rest of the Chads were minted for .0015Eth. We donated (5.5E) from this to retropgf.eth. We also received 8,606.59 OP from RPGF2 for education. 

Secondary royalties (5%) help keep the lights on but volume on Optimism has not been sufficient enough for us to be profitable.
