# Contractless CLI Tools

This file lists the command-line tools built from `src/bin`. On Windows, add `.exe` to each tool name. Most network lookup tools prompt for the wallet decryption key because the RPC handshake is authenticated before the request is sent.

Transaction creator tools produce signed transaction JSON and save it under `./transactions/` using the transaction hash as the filename. Creating a transaction does not submit it to the network; broadcast the saved JSON with `broadcast_transaction`.
