A Solidity app that simulates a lottery (for learning purposes). It contains tests written in Typescript, using Mocha.
It specifies a contract that allows players joining by paying at least .01 ether. The manager (who deployed the contract) can pick the winner using a pseudo-random code (the code is deterministic).
Before starting, make sure you install all npm dependencies by running:
yarn
To run the tests:
yarn test
To deploy the contract, create a .env file in the root folder (same where the package.json is located), and add the mnemonic and network deployment as below:
DEPLOY_MNEMONIC=invalid mnemonic dont try using this one because it wont work anyway DEPLOY_ENDPOINT=https://rinkeby.infura.io/v3/123a123a123a123a123a123a123a132
DON'T USE YOUR PERSONAL WALLET'S MNEMONIC. CREATE A NEW ONE FOR DEVELOPMENT!!!!
The mnemonic can be created via MetaMask (just create a brand new account, you'll get the mnemonic during the # process).
The URL you can get from Infura. Create your account, and setup a test project to retrieve your deployment url. I recommend using the Rinkeby network (not Mainnet). Happy coding :)
With the .env file in place (make sure not to commit it to any git repos), you can deploy with this command:
yarn deploy
Happy Coding :D
