Primary LanguageJavaScript

Sending ETH to many addresses

Web3 script that sends eth to multiple addresses.

How it works

The program will

  • read sender's private key from an env file
  • read a list of ethereum addresses from a JSON file.
  • read the amount of eth to send passed as an argument
  • make a gas estimation of the total cost
  • prompt the user for confirmation
  • build, sign and send 1 tx for every destination address

Usage:

  1. npm install
  2. create .env file with the following variables: 
     - PRIVATE_KEY
 - INFURA_KEY
 - WEB3_PROVIDER (i.e. "http://127.0.0.1:7545")
  3. Create json file with a list of addresses to send ether to. Example: 
     [
 "0x0000000000000000000000000000000000000001",
 "0x0000000000000000000000000000000000000002",
 "0x0000000000000000000000000000000000000003"
 ]
  4. Run the script with the following command: 
     node sendeth.js <amount> <path to json file>
