Ethereum, tokens & smart contracts.
Previous notes in case you are just joining us:Part 1. Setting up.
Part 2. Web3.js/node.
Part 3. Solidity.
Part 4. Smart Contracts.
Part 5. Smarter Contracts.
Part 6. Tokens & Inheritance.
Part 7. ERC20 Token Standard.
Part 8. Crowdfunding and ICOs.
Part 9. Dapps & MetaMask.
In this quasi finale note, I’d like to check and cover a few related tools ( Remix, Truffle & TestRPC) I left these for last but not least since I believe it is better to have some basic knowledge about contracts, tokens, Dapps & compiling before using them, they can also be viewed as helpful tooling for becoming more productive writing smart contracts.

Remix is a debugger, compiler & IDE for smart contracts, it is very accesible since you can start working with the online version immediately and a provider ( like metaMask ).
Note: Why not start with remix ? A lot of tutorials (including Ethereums ) recommend Remix as a starting point and that might work for some,I found it very confusing from the beginning, so I chose the path in these notes and I am glad I did since I believe working with clients, making your own compiler and interacting with the blockchain in other ways gives you a more robust foundation.Let’s start by going to remix and opening basicStorage.sol contract from part 4 of this notes :
You could of course create a new file and type it from scratch( or copy paste into remix) .Off the bat, remix proves useful by raising warnings…
In order to interact with the blockchain, you need to connect remix to it, here’s how you would connect it to…
