This is a Repository for learning about Blockchain Applications and cryptocurrencies. And also creating an blockchain application. The cryptocurrency I have used is Ether.

This is a web site for buying and selling tokens ERC-20 tokens for a fixed price

=> This is just for understanding how ERC-20 tokens, smart contracts works.

=>This is NOT A REAL TOKEN TRADING WEBSITE<=

=> If you have done setting up the development environment as given in setup.md then you can skip the below mentioned prerequisites and continue to Step 1.

Install these prerequisites.

• NPM: https://nodejs.org (install version: 9.10.0)
• Truffle: https://github.com/trufflesuite/truffle (install version: 5.1.14)
• Ganache: http://truffleframework.com/ganache/
• Metamask: https://metamask.io/

git clone https://github.com/Emmanuel1237/ERC-20-crypto-exchg.git

$ cd ERC-20-crypto-exchg
$ npm install

Open the Ganache GUI client that you downloaded and installed. This will start your local blockchain instance.

$ truffle migrate --reset 

You must migrate the Testchain smart contract each time you restart ganache.

• Click on the metamask icon on top right corner of the chrome browser
• Create an account on metamask.
• In metamask ,from networks section select custom RPC.
• In the new RPC URL section paste the RPC server URL displayed on the top tab of Ganache. And click save after giving a name for the network. Now we connected metamask to your local Etherum blockchain provided by Ganache.
• Now Import an account provided by ganache. Goto Ganache and click on the KEY icon corresponding to any account. It will diplay the private key of that account, copy in and open metamask, and click on the account icon ,select import account option and set the type to private key and paste the private key coppied below and click import.
• Now in metamask ,from networks section select the name of the network that you have created now.

$ npm run start

This will automatically star the web server and open up the client side website

Now start buying and selling tokens from your localhost network.
