Be careful using Ethereum tokens. I was wondering about ERC20. Developing smart contracts and learning more about this token standard I found some issues with ERC20 token usage. There are 2 different ways to transfer token: Use approve and transferFrom. Use transfer function. If you will choose the wrong way you will lose all transferred tokens.on Understand the ERC20 token smart contract. One of the most significant smart contract standard on Ethereum is known as ERC-20, which has emerged as the technical standard used for all smart contracts on the Ethereum blockchain for fungible token implementations. The ERC-20 defines a common list of rules that all Ethereum tokens must adhere to. Consequently, this token standard empowers developers of all types to accurately predict how new tokens will function within the larger Ethereum.I have found and deployed an ERC20 smart contract with a crowdsale function. I could set up: the number of initial tokens which were minted on my address when I deployed the contract; the number of tokens reserved to be minted in the crowdsale; the price of crowdsale: number of tokens / 1 ETH; I tested it and it's working as supposed. All great.I have 2+ years of experience in this field. I will create Solidity smart contracts or ERC20 tokens on Ethereum blockchain based on client requirements.
