I’m very new to developing so my apologies in advance. I rushed the release of my token to mainnet without accounting for crowdfunding/ico release. I’m confident I can update the token to allow for this on eth remix, but am having a hard time finding the proper files on openzepp. My token is a simple smart comtract protocol that is v.0.5.0. Does this mean I need to write my crowdfunding sol file using the same version? If not does anyone know of a simple crowdfunding sol file on here that will be best for my needs: (smart contract protocol…not simple token). Thank you in advance!
