Build bitcoin transactions

Usage: txtool [options] COMMAND [command parameters]

Options: -f, --file Load/store transaction state to/from FILE

Theory of operation

All operation revolves around an internal database, which is modified via execution of a command operation: 1. txtool reads transaction state file (JSON). Default "txstatedb.json". 2. txtool executes command given on command line, updating transaction state. 3. txtool writes transaction state file, overwriting previous version.

"transaction state" is anything involving the given transaction being built, examined or modified.

A session begins when a new database is initialized, using the "init" command.

pubkey.get ADDRESS

RPC: Obtain full pubkey, given bitcoin address (pubkey hash),
from bitcoind wallet.

pubkeys KEY1 KEY2 KEY3... Append to list of pubkeys / bitcoin addresses

pubkeys.clear Clear list of pubkeys.

raw SERIALIZED-TX Input serialized transaction from command line

raw.clear Clear serialized tx data.

raw.create RPC: create raw transaction, given inputs and outputs.

raw.decode RPC: decode raw transaction to readable JSON object.

raw.get TXID RPC: get raw transaction, given hash txid.

raw.read FILE Input serialized transaction from file.

raw.sign RPC: sign raw transaction, if possible. Uses keys in bitcoind's wallet.

raw.send RPC: broadcast raw transaction to network, returning a transaction id.

wallet.msig Commit in-memory multisig data (N-Required, Keys) to RPC wallet, returning a multisig payment address.

Encryption (walletpassphrase) note

The user is expected to authenticate with bitcoind RPC prior to using this tool, if this tool will require access to private keys for the operation (e.g. signing).
