Development-Envirnoment

If you are an Ethereum developer, you're also a Nahmii developer, as the tools used on Ethereum are supported on Nahmii; Remix, Web3js, OpenZeppelin, Hardhat, etc. Make the switch to Nahmii's RPC and get started.

Nahmii Test Network connects with Ethereum's Rospten Testnet, and all network-related details can be found here.

Deploy your contracts on Nahmii using

• Hardhat

• Remix

Setting up the development environment

Via Hardhat

There are a few requirements, please install the following to get started:

1. Node.js v12+ LTS and npm

2. Git

• Install the NVM Hardhat plugin.

yarn add @nahmii/hardhat-nvm 

• Edit hardhat.config.js to use the NVM package.

// hardhat.config.js
require("@nomiclabs/hardhat-waffle");
require('@nahmii/hardhat-nvm')

...

• In the file, add nahmii to the list of networks. Note: Update the accounts fields to fit your personal setup.

...

module.exports = {
  solidity: "0.7.6",
  networks: {
    nahmii: {
      url: 'https://l2.testnet.nahmii.io/',
      accounts: { mnemonic: 'test test test test test test test test test test test junk' },
      gasPrice: 15000000,
      nvm: true
    }
  }
};

• To test contracts on the live Nahmii L2, compile it with HardHat.

npx hardhat --network nahmii test

• To interact with the smart contracts manually, use the console. The JavaScript console can be run with the following command.

npx hardhat --network nahmii console

• To deploy to Nahmii, write a deploy script for HardHat (https://hardhat.org/guides/deploying.html) and run the following command.

npx hardhat --network nahmii scripts/deploy.js

Via Remix

Remix is an online IDE to develop smart contracts

Configuration

1. In a new remix workspace, navigate to the PLUGIN MANAGER.

2. Activate the OPTIMISM COMPILER.

3. A new compiler tab will show up. Select a Solidity file to compile. Be sure to select the correct compiler version for your smart contract.
