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.
txtool command summary
dump Inspect transaction state database.
help List this command summary.
init Initialize new transaction state database.
inputs TXID1 VOUT1 TXID2 VOUT2... Raw transaction building. Append to list of TX inputs.
inputs.clear Clear list of TX inputs.
multisig N-REQUIRED KEY1 KEY2 KEY3... Begin new multi-sig tx
nreq N-REQUIRED Specify number of sigs required for a multisig tx
outputs ADDRESS1 VALUE1 ADDRESS2 VALUE2... Raw transaction building. Append to list of TX outputs.
outputs.clear Clear list of TX outputs.
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.append FILE Append FILE to in-memory serialized transaction data.
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.write FILE Output serialized transaction to file.
raw.sign [anyonecanpay] RPC: sign raw transaction, if possible. Uses keys in bitcoind's wallet.
If the optional argument "anyonecanpay" is supplied,
outputs are locked, but third party inputs may change.
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).
