#To install hardhat tools and create project

#Create moonbeam node

In order to create your node on internet (no buy ou swap coin, only transfer and call contract)

```use docker-compose -f docker-compose-with-traefik up -d```

It deploy a blockchain node and nginx server to make test.

All example of html file are in webpage directory

Note: when you purge your node (restart for example), you need to clear all transaction from account in metamask

To view blockchain like etherscan, you can use :

https://polkadot.js.org/apps

And change config in developpement menu, for example, to view my node :

https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fmoon-ws.nuage.omvpb.ovh#/explorer/query/0x26a9456aaf24d12f195d9301136d11ce1815e85d3234d98d2a595e75339bebdb

```

sudo apt update

sudo apt install curl git

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -

sudo apt install nodejs

```

to create a project and directory :

```

npm init --yes

npm install --save-dev hardhat

npm install @nomiclabs/hardhat-ethers ethers @nomiclabs/hardhat-waffle ethereum-waffle chai

npm install web3

npx hardhat (and select empty project)

```

Moombean node provide you 10 ten accounts for testing.

Install Node moombean for developpement (with docker) :

```

version: '3'

services:

  polkadot:

    image: purestake/moonbeam:v0.18.1

    ports:

      - "30333:30333"

      - "9933:9933"

      - "9944:9944"

    command: --dev --rpc-external --ws-external

```

The accounts_moombean contains all account with public adress and private key

Copy paste this config and change IP according to your moombean installation docker dev :

```

// ethers plugin required to interact with the contract

require('@nomiclabs/hardhat-ethers');

// private key from the pre-funded Moonbase Alpha testing account

const { privateKey } = require('./secrets.json');

module.exports = {

  // latest Solidity version

  solidity: "0.8.1",

  networks: {

    moonbase: {

      url: 'http://185.189.157.205:9933',

      chainId: 1281, // 0x507 in hex,

      accounts: [privateKey]

    }

  }

};

```

You need to have a secrets json file that contains one private key on a pre-configured account offer by moombean dev

Create your contract (see directory)

Compile your contract :

```

npx hardhat compile

```

# To deploy the contract :

```

npx hardhat run --network moonbase scripts/deployXXX.js
