- It is important when we talking about how to Build own Ethereum Token with Solidity to keep in our minds that there are two types of cryptocurrencies: – – one is coin and the other one is token.
- Difference between coins and token – – The main difference between coins and token that you should know before you Build own Ethereum Token with Solidity is that: – – Coins have their own blockchains.
- This is the basic code and all you need to do is go to the Ethereum GitHub solidity ide and paste your token right there.
- Congratulation you Build own Ethereum Token with Solidity and you have your own CCX – – You have your own coin and if you go to the Ethereum scan.
- Now I Built my own Ethereum Token and I have my own coin and I can sell it to the public.

- this is probably a really really simple question but shamefully it’s had me stumped for a while.
- I am building a simple application which would allow users to purchase Newspaper Articles.
- Simple enough but the relations is killing me.
- An Author, An Article and A Reader – – An Author can have many Articles – – An Article can have one Author – – An Article can have many Readers – – A Reader can have many Articles – – An Author and a Reader have no relation -…
- I’m sure this is simple so any advice would be appreciated, – – My code is pretty rubbish for now so I don’t think it will help posting it

- I’m working with an ERC20 token and when I instantiate a new instance of it and try to receive its symbol in my tests, I receive a hex representation of the string.
- The relevant code for the ERC20 token is the following – – When I log out I get the following instead of DAI – – Any explanations and suggestions are appreciated!
