Sign and Send IOTA

Alpha Software

The IOTA SDK is currently in alpha. APIs, interfaces, and behavior may change without notice between releases. It is not yet recommended for production use.

This how-to demonstrates how to sign and execute an IOTA transfer transaction on localnet.

info

This example runs on localnet. Make sure you have a local IOTA node running before executing the code.

Prerequisites​

  • The IOTA SDK installed for your target language
  • A running local IOTA node

Steps​

1. Define the Recipient Address and Private Key​

Create a throwaway Ed25519 private key from a zeroed byte array and derive the sender address from it.
