BITCOIN-TX(1) User Commands BITCOIN-TX(1) NAME bitcoin-tx - manual page for bitcoin-tx v31.0.0 SYNOPSIS bitcoin-tx [options] <hex-tx> [commands] bitcoin-tx [options] -create [commands] DESCRIPTION Bitcoin Core bitcoin-tx utility version v31.0.0 The bitcoin-tx tool is used for creating and modifying bitcoin transac- tions. bitcoin-tx can be used with "<hex-tx> [commands]" to update a hex-encoded bitcoin transaction, or with "-create [commands]" to create a hex-encoded bitcoin transaction. OPTIONS -create Create new, empty TX. -help Print this help message and exit (also -h or -?) -json Select JSON output -txid Output only the hex-encoded transaction id of the resultant transac- tion. -version Print version and exit Debugging/Testing options: Chain selection options: -chain=<chain> Use the chain <chain> (default: main). Allowed values: main, test, testnet4, signet, regtest -signet Use the signet chain. Equivalent to -chain=signet. Note that the network is defined by the -signetchallenge parameter -signetchallenge Blocks must satisfy the given script to be considered valid (only for signet networks; defaults to the global default signet test net- work challenge) -signetseednode Specify a seed node for the signet network, in the hostname[:port] format, e.g. sig.net:1234 (may be used multiple times to specify multiple seed nodes; defaults to the global default signet test net- work seed node(s)) -testnet Use the testnet3 chain. Equivalent to -chain=test. Support for test- net3 is deprecated and will be removed in an upcoming release. Con- sider moving to testnet4 now by using -testnet4. -testnet4 Use the testnet4 chain. Equivalent to -chain=testnet4. Commands: delin=N Delete input N from TX delout=N Delete output N from TX in=TXID:VOUT(:SEQUENCE_NUMBER) Add input to TX locktime=N Set TX lock time to N nversion=N Set TX version to N outaddr=VALUE:ADDRESS Add address-based output to TX outdata=[VALUE:]DATA Add data-based output to TX outmultisig=VALUE:REQUIRED:PUBKEYS:PUBKEY1:PUBKEY2:....[:FLAGS] Add Pay To n-of-m Multi-sig output to TX. n = REQUIRED, m = PUBKEYS. Optionally add the "W" flag to produce a pay-to-witness-script-hash output. Optionally add the "S" flag to wrap the output in a pay-to-script-hash. outpubkey=VALUE:PUBKEY[:FLAGS] Add pay-to-pubkey output to TX. Optionally add the "W" flag to pro- duce a pay-to-witness-pubkey-hash output. Optionally add the "S" flag to wrap the output in a pay-to-script-hash. outscript=VALUE:SCRIPT[:FLAGS] Add raw script output to TX. Optionally add the "W" flag to produce a pay-to-witness-script-hash output. Optionally add the "S" flag to wrap the output in a pay-to-script-hash. replaceable(=N) Sets Replace-By-Fee (RBF) opt-in sequence number for input N. If N is not provided, the command attempts to opt-in all available inputs for RBF. If the transaction has no inputs, this option is ignored. sign=SIGHASH-FLAGS Add zero or more signatures to transaction. This command requires JSON registers:prevtxs=JSON object, privatekeys=JSON object. See signrawtransactionwithkey docs for format of sighash flags, JSON ob- jects.
