I'm a Blockchain developer and consultant with a lot of expertise. I work with cutting-edge technology:- Blockchain: 1. Create an ERC20 standard token using the most secure version of Solidity code. 2. Create ERC223 standard tokens with the most secure version of Solidity code. 3. A crowdsale token contract with the ability to automatically transfer ether to the owner's wallet once the contract is completed, as well as an immediate token transfer to the buyer. Cibus Token, Investa Coin, Thanecoin, and more than 50 more ICO tokens are examples.
