Transfer ETH Using Node.js: A Step-by-Step Guide

Introduction

In this tutorial, we'll explore Ethereum development environment setup and demonstrate how to transfer ETH programmatically using Node.js. Whether you're testing locally or on a public testnet, this guide provides clear instructions to get you started.

Ethereum Development Environments

Ethereum offers three primary environments for development:

Local Test Network: Ideal for initial development and debugging.
Public Test Networks:
- Ropsten
- Rinkeby
- Kovan
- Goerli
Mainnet (Production): The live Ethereum blockchain.

Step 1: Quickstart with Ropsten Testnet

1.1 Generate a Test Wallet

Use a mnemonic phrase generator to create a 12-word seed phrase.
Save the phrase securely and note the first address (Account[0]).

1.2 Acquire Test ETH

Visit the Ropsten Faucet and request 1 ETH for Account[0].

1.3 Set Up Infura

Register at Infura.
Copy your Ropsten RPC URL (e.g., wss://ropsten.infura.io/v3/xxxxx).

1.4 Execute the Transfer

Clone and configure the ethereum-demo repository:

git clone https://github.com/netpi/ethereum-demo.git  
cd ethereum-demo  
npm install

Update ropsten.config.js with your mnemonic and Infura RPC URL. Run:

node transferEth.js

Successful transfers will display a transaction hash. Verify it on Etherscan.

Step 2: Local Development with Ganache

2.1 Install Ganache

Download Ganache and input your mnemonic phrase under Settings > Accounts & Keys.

2.2 Run Local Transactions

Update local.config.js with your mnemonic and Ganache RPC URL (default: http://127.0.0.1:7545). Execute:

node transferEth.js

Check Ganache’s interface to confirm balances and transaction details.

FAQs

Q1: Why use Ropsten before local testing?

A1: Ropsten mimics Mainnet behavior closely, making it easier to understand real-world interactions before switching to local simulations.

Q2: How do I secure my mnemonic phrase?

A2: Store it offline in encrypted form and never share it. Hardware wallets are recommended for production use.

Q3: What if my transaction fails?

A3: Verify gas fees, network connectivity, and address validity. Testnets often require higher gas limits than local networks.

Conclusion

You’ve now successfully:
✔ Transferred ETH on Ropsten Testnet
✔ Configured a local Ganache environment
✔ Executed programmatic transactions

In upcoming guides, we’ll dive deeper into Web3.js, mnemonic security, and smart contract deployment.
