License and Legal Agreement

IMPORTANT

This application and its code is NOT free to use, modify or resale. By using it you agree to not violate Plagiarism and Copyright Infringment

In order to use application code for modification or on own projects please contact info@ibnz.co.uk to obtain full licence.

The idea of me including licensing and restrictions is mainly to protect users from reselling the software. The software was created for educational purposes and should be used mainly as a reference. 
However, there are a few very successful projects who are using my code without giving credit back. My application description is included on their whitepaper, where developers claim that this is the product they developed.  Some haven't even changed the UI :)

In order to stop scenarios like this, I included a little description where I mention the License for the software.  
The License is a written agreement from me that issues full rights to modify, resell, and use software and code without giving credit to the author or original repo. 

The License fee is 0.3 ETH
I charge everyone the same price and I found this to be a genuine and fair price to charge.

Running instructions

• Copy project to your directory ( git clone https://github.com/ibnzUK/Token-Staking-dApp )
• Install project packages (npm install)
• Start project (npm run start)

For Testing

• To run tests, navigate to /test/TokenStaking and run: truffle test

For Admin Use

• There are prewritten scripts for Admin use either manually or on daily, weekly basic, ideally with predefined cronjob from the server.
• All scripts are located in /scripts folder
• To change APY % run: truffle exec scripts/changeAPY.js 0.137 this script takes 1 argument (daily APY), in this provided example, admin sets 0.137 daily APY
• To redistribute rewards from the console, run: truffle exec scripts/redistribute.js or provide argument custom if you want to redistribute custom rewards

Deployoment to Ethereum network and Verification

For private Ethereum test network make sure Ganache is running on HTTP://127.0.0.1:7545

• First configure truffle-config.js with your infura key and mnemonic key. You can reate files in top dirrectory under names .infuraKey and .secret and paste your keys in there
• If you planning to publish your project on github make sure you .gitignore your keys
• Compile smart contracts with truffle compile
• Deploy to your local (Ganache) network run: truffle migrate --reset or for Ethereum test network (Rinkeby) run: truffle migrate --network rinkeby --reset or change rinkeby to ropsten
• To verify contract code on Ethereum test network add your Etherscan API key to .ethKey and for (Rinkeby) run: truffle run verify TestToken --network rinkeby or change rinkeby to ropsten
