So, here a quick details about my setup. I am using Truffle. I am using OpenZeppelin v3 for my ERC-20 token and v2.5 for my crowd sale. Apart from that, I am using Chainlink (installed via npm) to fetch some data.
I am struggling a bit on how to make my contracts upgradeable. I don’t clearly understand the concept I guess, Do I have to run everything I am doing inside the constructor in “initialize”. If someone can share an example of something like an ERC-20, that would be great.
P.S;- Sorry for so many questions in the past 2-3 days. It’s just my first full-fledged blockchain product launch and I am really nervous about it.
