Do I need to change my contract source code?
This depends on the type of certificate you acquired. For the most basic certification, you only need to add very minor code snippets. We have prepared in-depth text and video tutorials to assist you in this. For more advanced variants, you may need to import additional code that we will provide.
You may also use our code templates on our GitHub repository. Rest assured, our code is based on OpenZeppelin smart contract templates.
