Usage

• Go to https://datahighway.herokuapp.com
• Choose faucet:
  • Ropsten Testnet ETH
  • MXC ERC-20 tokens
• Enter Ethereum Address to receive
• Click Submit

Note: Faucet only works when:

• Requestor's Ropsten ETH balance < 1 MXC
• Requestor's Ropsten MXC ERC-20 token balance < 1 MXC
• Faucet's Ropsten ETH balance > 0.01 ETH
• Faucet's Ropsten MXC ERC-20 token balance > 0.01 MXC
• Requestor's Ethereum address that is not a smart contract, otherwise out of gas error may occur, since only a limited gas price has been catered for.

Development

• Install dependencies and run server and front-end.

nvm use;
yarn global add nodemon;
DEBUG=app yarn dev;

• Go to http://localhost:3000
• Enter your Ethereum address to receive either Ropsten Testnet ETH or MXC ERC-20 tokens
