11.SH DESCRIPTION
12Bitcoin Core bitcoin\-tx utility version v32.1.0
13.PP
14The bitcoin\-tx tool is used for creating and modifying bitcoin transactions.
15.PP
16bitcoin\-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.
17.SH OPTIONS
18.HP
19\fB\-create\fR
20.IP
21Create new, empty TX.
22.HP
23\fB\-help\fR
24.IP
25Print this help message and exit (also \fB\-h\fR or \-?)
26.HP
27\fB\-json\fR
28.IP
29Select JSON output
30.HP
31\fB\-txid\fR
32.IP
33Output only the hex\-encoded transaction id of the resultant transaction.
34.HP
35\fB\-version\fR
36.IP
37Print version and exit
38.PP
39Debugging/Testing options:
40.PP
41Chain selection options:
42.HP
43\fB\-chain=\fR<chain>
44.IP
45Use the chain <chain> (default: main). Allowed values: main, test,
46testnet4, signet, regtest
47.HP
48\fB\-signet\fR
49.IP
50Use the signet chain. Equivalent to \fB\-chain\fR=\fI\,signet\/\fR. Note that the network
51is defined by the \fB\-signetchallenge\fR parameter
52.HP
53\fB\-signetchallenge\fR
54.IP
55Blocks must satisfy the given script to be considered valid (only for
56signet networks; defaults to the global default signet test
57network challenge)
58.HP
59\fB\-signetseednode\fR
60.IP
61Specify a seed node for the signet network, in the hostname[:port]
62format, e.g. sig.net:1234 (may be used multiple times to specify
63multiple seed nodes; defaults to the global default signet test
64network seed node(s))
65.HP
66\fB\-testnet\fR
67.IP
68Use the testnet3 chain. Equivalent to \fB\-chain\fR=\fI\,test\/\fR. Support for testnet3
69is deprecated and will be removed in an upcoming release.
70Consider moving to testnet4 now by using \fB\-testnet4\fR.
71.HP
72\fB\-testnet4\fR
73.IP
74Use the testnet4 chain. Equivalent to \fB\-chain\fR=\fI\,testnet4\/\fR.

98outaddr=VALUE:ADDRESS
99.IP
100Add address\-based output to TX
101.IP
102outdata=[VALUE:]DATA
103.IP
104Add data\-based output to TX
105.IP
106outmultisig=VALUE:REQUIRED:PUBKEYS:PUBKEY1:PUBKEY2:....[:FLAGS]
107.IP
108Add Pay To n\-of\-m Multi\-sig output to TX. n = REQUIRED, m = PUBKEYS.
109Optionally add the "W" flag to produce a
110pay\-to\-witness\-script\-hash output. Optionally add the "S" flag to
111wrap the output in a pay\-to\-script\-hash.
112.IP
113outpubkey=VALUE:PUBKEY[:FLAGS]
114.IP
115Add pay\-to\-pubkey output to TX. Optionally add the "W" flag to produce a
116pay\-to\-witness\-pubkey\-hash output. Optionally add the "S" flag to
117wrap the output in a pay\-to\-script\-hash.
118.IP
119outscript=VALUE:SCRIPT[:FLAGS]
120.IP
121Add raw script output to TX. Optionally add the "W" flag to produce a
122pay\-to\-witness\-script\-hash output. Optionally add the "S" flag to
123wrap the output in a pay\-to\-script\-hash.
124.IP
125replaceable(=N)
126.IP
127Sets Replace\-By\-Fee (RBF) opt\-in sequence number for input N. If N is
128not provided, the command attempts to opt\-in all available inputs
129for RBF. If the transaction has no inputs, this option is
130ignored.
131.IP
132sign=SIGHASH\-FLAGS
133.IP
134Add zero or more signatures to transaction. This command requires JSON
135registers:prevtxs=JSON object, privatekeys=JSON object. See
136signrawtransactionwithkey docs for format of sighash flags, JSON
137objects.
138.PP
