Store your promises in the blockchain and bet some money against it. If you fail, you lose 50% of your bet, otherwise you get 100% back 🤣. Don't worry though, it runs on the Rinkeby testnet, so you won't be playing with any real money.

• Web3
• Solidity (solc)
• React

The development part of this project can be divided into 3 parts.

1. Smart contract deployment (on local or test networks)
2. Smart contract testing
3. Web app development

For deploying on Ganache (GUI version) local test network

# run ganance before this
npm run deploy:local

For deploying on Rinkeby testnet

# export from .env
npm run deploy:testnet

You will have to set up the keys in .env file. Private key is private key of the address that is deploying and infura project ID is the project ID at Infura.

Run the test script. The following command run tests on the smart contract using Waffle.

npm run build:waffle
# ^ build if smart contract changes or not built already
npm test

Copy the contract ABI and the contract addresses generated by deploy script to lib/sc.js. Then run the following -

npm run start

Smart contract deployments have already been covered in the previous section.

To deploy the web app, first build it

npm run build

Then deploy it on surge.sh.

npm run deploy:web
