Prerequisites

1. Install NodeJS
2. Install Truffle(Solidity development tool)
3. Install MetaMask browser extension
4. Deposit ETH to your MetaMask
5. Register Infura.io and get project ids (infura keys)

Install NodeJS with NVM

For OSX

touch ~/.bash_profile
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
nvm install 11.11.0
nvm use 11.11.0
node -v && npm -v

Install truffle & truffle-flattener

Truffle is required to be global by some libraries.

Global here means global under a specific node version, not system global.

npm i -g truffle
npm i -g truffle-flattener

Install

git clone https://github.com/hackers-live/erc20-token-template.git your_token_name
cd your_token_name
npm install

Configure your account

1. Configure account by runningecho <your_address_on_metamask> > .account
2. Configure mnemonic by running echo <your_mnemonic> > .secret
3. Configure infura key by running echo <your_infura_key> > .infura_key

Customize your token

1. Open contracts/MyCoin.sol
2. Edit cap, name, symbol and decimals.
3. That's it.

Test on local

Start REPL

truffle develop

Deploy

migrate

Once deployed, you can access your token as below

token = await MyCoin.deployed()
token.name()
token.totalSupply()

Deploy to ropsten/main network.

Ropsten

truffle console --network ropsten

migrate
token = await MyCoin.deployed()
accounts = web3.eth.getAccounts()
token.balanceOf(accounts[0])
token.mint(accounts[0], web3.utils.toWei("1000", "ether"))
token.balanceOf(accounts[0])

Main

The command below consumes your real ETH.

truffle migrate --network main

Don't forget write down your contract address or transaction hash.

They are stored build/contracts/MyCoin.json.

If your project keeps on going, commit them to your repository.

Migrations which have been already applied are skipped in the next migration.

Flatten your token

"Flatten" is conpiling all contract files into a file.

This is required to submit source code to Etherscan or exchanges and so on.

truffle-flattener contracts/MyCoin.sol > output.sol

And use output.sol
