  • Best ways to learn basic smart contract functionality?
    reddit.com/r/ethereum | 2021-04-06
    So to answer your original question, I guess my question is do you already know how to program in a language like Python or Java? If so, learning solidity still has a curve but isn't too bad, there's a lot of similarities to any statically typed OOP language. I've been using remix which has a few good tutorials on how to write and deploy smart contracts. From there I've mostly just been scanning through the solidity docs or reading code from open source libs like OpenZeppelin. I also use Ganache to run my own ETH testnet to test against.

    reddit.com/r/ethdev | 2021-03-20
    I found the OpenZeppelin contracts (https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/contracts/token) and as far as I can tell these would be the best place to start, hopefully bug-free. My end goal though is to create an auction site, similar to Open Sea or some of the other NFT sites. Is OpenZeppelin a good place to start or are there other well-tested, robust contract code I'm not aware of?

    reddit.com/r/ethereum | 2021-03-15
    If you want to create a basic ERC20 token with no extra functionality, openzepplin has some libraries that let you do it with like 5 lines of code. I had a new token deployed to a test network within about 15 minutes (deploying to mainnet is like $200+ so I'll pass on that for now lol). You can then customize it from there to add whatever functionality you want.

    It seems that the popular minting marketplaces out there haven’t included this functionality in their smart contract code yet, but you could certainly get a developer who’s experienced with writing custom contracts to do this for you. Especially because one need not start from scratch. Libraries like openzepplin have created implementations of the ERC721 standard so that a dev need only tweak the contract (and go through the necessary steps for testing and auditing for potential issues of course - this is important because one a smart contract deployed to the Ethereum network and available for use, the code for the most part can’t be altered).

    On the one hand, it is common for an ERC20 to implement a burn operation. The burn is typical in certain DeFi tokens that essentially commit a stock buy back. The problem with this implementation, is onlyOwner and contracts that pass the whitelisting modifier can burn from anyone's address. This is pretty bad. Standard practice seems to be burning only from the caller address. A good example is OpenZeppelin's Burnable implementation here: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/extensions/ERC20Burnable.sol#L34-L39.

    Consider Ethereum. Smart contracts can move both ETH and ERC20 tokens but they're not the same because ERC20 is a contract template that is standardized and ETH is a native 1st class token. If someone screwed up ERC20 implementation he could screw up token enforcement rules. You can't screw up NGT enforcement rules whatever you do in script. As a recipient of some token, you wouldn't need to check whether it is a standard one or not, in which case you'd have to verify the soundness of the contract yourself.
  • Hi I’m new and have a few seemingly dumb questions I do t want to bombarded the sub with scan someone help please
    I can't say if you will be successful in getting people to use your coin, but you may find it quite easy to write up a token contract. OpenZeppelin provides a great ERC20 base contract which you can build off of.

    I would use https://github.com/OpenZeppelin/openzeppelin-contracts as they have a lot of code you may reuse including ERC20 token contract.
