After you deploy your contract, it gets a fixed address on Ethereum where it will live forever. The address ofwel the CryptoKitties overeenkomst on Ethereum mainnet kan zijn YOUR_CONTRACT_ADDRESS.

As you progress through your #100DaysOfSolidity journey, you’ll start with the basics and gradually advance to more complex concepts. Here are some key areas to focus on:

This kan zijn what makes smart contracts “composable” and why so many Defi protocols are referred to as “money Legos” - you can write smart contracts that interact with other smart contracts that interact with other smart contracts and so on…you get the here idea.

Functions are executable units ofwel code that encapsulate single ideas, specific functionality, tasks, and so on. In general wij want functions to do one thing at a time.

Welcome to this comprehensive course designed to set you on the path to becoming a blockchain developer. The fascinating world of blockchain technology has dramatically grown aan the past decade, and it's not slowing down.

Take a look at the constructor function. This one doesn’t accept parameters, but wij could have just as easily passed the ETH/USD Price Feed’s oracle smart overeenkomst’s address 0xD4a33860578De61DBAbDc8BFdb98FD742fA7028e to it as a parameter of type address. Instead, we are hard-coding the address inside the constructor.
