New Crowdsale Contract (Template and Code Examples)

trevoro1 · January 31, 2022, 1:24pm

I worked in depth with solidity some years ago, but moved to other languages (eg chaincode/nodejs, Java, Rust) - I am now returning to solidity and I saw a lot of changes - for the latest versions. I used to use examples of contracts I took from verified contracts in etherscan (based on OpenZepplin). Has anyone a contract example they recommend, I mean by recommend just saying it is a good example to follow not that is completely safe from hacking?

hey @trevoro1
I made an example months ago, it is not the best option and can be improved in many parts. I made it at the start but you could try to start from this.

github.com

FreezyEx/PreSale-Contract/blob/main/NAME-Presale.sol

pragma solidity ^0.8.4;
// SPDX-License-Identifier: Unlicensed


abstract contract Context {
    function _msgSender() internal view virtual returns (address payable) {
        return payable(msg.sender);
    }

    function _msgData() internal view virtual returns (bytes memory) {
        this; // silence state mutability warning without generating bytecode - see https://github.com/ethereum/solidity/issues/2691
        return msg.data;
    }
}



contract Ownable is Context {
    address private _owner;

Thanks for your reply. I was really seeking something proved in an actual ICO (ie verified on etherscan) to reduce the risk of it being attacked successfully.
