Hello @abcoathup
I’m currently working on a video game that integrates a cryptocurrency. I want to be able to do a basic crowdsale, but I also want to use Open Zeppelin audited smart contract to ensure that funds won’t disappear from earth. Is it still safe to use the v2.0 Crowdsale smart contract ? Is their any chance that there are new vulnerabilities due to the old solidity version used here ? Or would you just use v3.0 contracts and extend them until you have all the required functionalities (Personally I would prefer using the old 2.0 if it’s fine)?
Hello @beuman, welcome to the community! Feel free to introduce yourself in the Introduce yourself here! topic
I’d go with 2.0
for the crowdsale, extending 3.0
would imply to write a lot of logic by yourself and the more custom logic the more room for mistakes there is. You can then use the latest version for the rest of your contracts.
Hi @beuman,
Welcome to the community
Gas prices during network congestion can significantly impact applications such as gaming, so something you might want to consider. I also suggest having a look at: Points to consider when creating a fungible token (ERC20, ERC777).
Hi @abcoathup, @martriay Just wondering if is still safe to use Crowdsale smart contract particularly with tags 2.5.1? We are planning to implement a crowdsale feature IDO.
I hope you could reply to this.
Thanks for reading and have a great day!
