Yeah, you are right, it only exists in the version 2.x, they are not in OpenZeppelin Contracts 3.x.

So to install it, you can run the following command:

npm install @openzeppelin/contracts@2.5.1

And you can find more details in the documentation: https://docs.openzeppelin.com/contracts/2.x/crowdsales

I have added :warning: emoji to the Simple ERC20 Crowdsale to make it clearer that they are not in OpenZeppelin Contracts 3.x

Hi @asven-2020,

There aren’t specific presale contracts. You could have multiple crowdsale contracts for each phase.

Hi @asven-2020,

You can have a separate project for the token and a separate project for the crowdsale. This would allow you to have a token using the latest OpenZeppelin Contracts (depending on the token).

Is there a new Crowdsale contract or did OPZ just stop maintaining it altogether. I tried using the 2x contract and could never get the transfer function to work at all.

If you know of any newer contract please advise.
