cheapETH transaction example

This node web3 example uses a local wallet (the private key is saved in a file -.private-key.txt), connects to a public JSON RPC node (running a full node is not required), and uses sendSignedTransaction() to broadcast the locally signed transaction.

• sample code
• based on web3
• uses makevoid/ethereum-keychain minimalistic library
• light / web client (no full node required)
• the private key is saved on your system as a file
• requires very little code

• generate a private key (key needs to be a Bitcoin key in WIF format saved in .private-key.txt)

• use metamask or any other ethereum wallet to move some funds (e.g. 1 cTH) to your account (your ethereum address)

• run node main.js to send a sample transaction

• customize the code (add a real sender, change the gasPrice amount, add data, etc...)

• profit! :D
