### Notes

- Remix: allows you to write Solidity code; allows you to write, compile, and run the code on eth blockchain

  - remix.ethereum.org

- Remix has templates and tutorials for smart contracts

- a smart contract is basically a function that is defined with the `contract` keyword

- you can declare a variable like this:

```solidity

contract SampleContract {

    string public name = "some name";

}

```

- the `name` variable can be accessed by using a call

  - a call is a zero-cost transaction you can make on the blockchain to access data, such as this stored variable value

- smart contracts use NatSpec style comments as well as standard ones (see the sample contract code file for examples)

- smart contract creates get() methods under the hood to read the data in it

  - you do have to create setter functions yourself

  - this is because the setters will usually require logic

  - setters utilize functions and actions

    - call it a "function" because a function does something, with rules and parameters
