## Installation Steps

Add your mnemonic and infura url in `.env` file, just rename the file `.env_sample` and fill it.

Example:

- `MNEMONIC="bla bla bla... "`
- `INFURA_URL=https://sepolia.infura.io/v3/<YOUR_INFURA_KEY>`

Install the dependencies

``` bash 
npm install
```
Compile smart-contract locally inside `builds` folder

``` bash
npm run compile
```

Run test with _Mocha_
``` bash 
npm run test
```

Deploy on infura or on the provider you prefer
``` bash
npm run deploy
```

_Contracts present in the folder `contracts`:_

- **AuthContract**: register user, authenticate, getPublicKey
- **LotteryContract**: register user, buy lottery ticket, claim lottery ticket
- **Campaign**: for every kind of campaign like kickstarter, this contract includes a **Factory functions**

## INFO

The smart contracts are deployed to the [Infura](https://app.infura.io/) testnet. But you can also
use [Remix](https://remix.ethereum.org/).

#### Prerequisites

You need to install **MetaMask** and connect it to the testnet for deploying the contracts.

## Instruction

In this repo, inside folder `contracts` there are:

- Authentication.sol
- Lottery.sol
- Campaign.sol 
  - CampaignFactory.sol

You can use it for testing the service.

What appears on consolle after lunch command `npm run deploy`:
```text
Enter the contract name (**without .sol extension**): <CONTRACT_NAME>
```

The result on the terminal will be like this:

``` text 
Attempting to auth from account 0xA9D3cxxxxxxx14C5Ac96f211F2
