I have a certain amount of ERC20 Tokens. How can I Create a crowdsale contract that allows me to send them to it to be sold?

Question

I have created previous contracts where the token is created by the crowdsale and then the constructor allocates an amount of those to be transferred to other addresses and the remainder are for sale.

But how do I implement logic that allows me to set an already created token as the token to be used in the crowdsale and then send those tokens to the contract and have them for sale?

Thanks for any help.

Answer 1

It depends on who currently owns the tokens which you want to sell in the crowdsale. You need to have a way to transfer those tokens somewhere. If you have this access, you can just write a crowdsale contract which references the token contract and calls its methods to send the tokens elsewhere with some logic (crowdsale).

Here's an example crowdsale: https://github.com/OpenZeppelin/openzeppelin-solidity/blob/master/contracts/examples/SampleCrowdsale.sol

Answer 2

I think what you are looking for is an Escrow smart contract implementation.
