thankyou for your answer to 1
for 2, I feel i have tried this. Just tried again.... i click on the get polycub-usdc lp link which takes me to sushi swap where usdc is filled in but the other is a blank token, so I click add token and type in the polycub address but nothing shows up. Not sure if im misunderstanding a step or if its something to do with my browser or something?
