The createpsbt RPC creates a transaction in the Partially Signed Transaction format. Implements the Creator role.
createpsbt [{"txid":"hex","vout":n,"sequence":n},...] [{"address":amount,...},{"data":"hex"},...] ( locktime replaceable )
*bitcoin-cli help createpsbt
createpsbt [{"txid":"hex","vout":n,"sequence":n},...] [{"address":amount,...},{"data":"hex"},...] ( locktime replaceable )
Creates a transaction in the Partially Signed Transaction format.
Implements the Creator role.
Arguments:
1. inputs (json array, required) The inputs
[
{ (json object)
"txid": "hex", (string, required) The transaction id
"vout": n, (numeric, required) The output number
"sequence": n, (numeric, optional, default=depends on the value of the 'replaceable' and 'locktime' arguments) The sequence number
},
...
]
2. outputs (json array, required) The outputs (key-value pairs), where none of the keys are duplicated.
That is, each address can only appear once and there can only be one 'data' object.
For compatibility reasons, a dictionary, which holds the key-value pairs directly, is also
accepted as second parameter.
[
{ (json object)
"address": amount, (numeric or string, required) A key-value pair. The key (string) is the bitcoin address, the value (float or string) is the amount in BTC
...
},
{ (json object)
"data": "hex", (string, required) A key-value pair. The key must be "data", the value is hex-encoded data
},
...
]
3. locktime (numeric, optional, default=0) Raw locktime. Non-0 value also locktime-activates inputs
4. replaceable (boolean, optional, default=true) Marks this transaction as BIP125-replaceable.
Allows this transaction to be replaced by a transaction with higher fees. If provided, it is an error if explicit sequence numbers are incompatible.
Result:
"str" (string) The resulting raw transaction (base64-encoded string)
Examples:
> bitcoin-cli createpsbt "[{\"txid\":\"myid\",\"vout\":0}]" "[{\"data\":\"00010203\"}]"
