The createpsbt RPC takes a list of inputs and outputs and converts them to a PSBT with no additional information. It is equivalent to calling createrawtransaction followed by converttopsbt.
createpsbt [{"txid":"id","vout":n},...] [{"address":amount},{"data":"hex"},...] ( locktime ) ( replaceable )
*bitcoin-cli help createpsbt
createpsbt [{"txid":"id","vout":n},...] [{"address":amount},{"data":"hex"},...] ( locktime ) ( replaceable )
Creates a transaction in the Partially Signed Transaction format.
Implements the Creator role.
Arguments:
1. "inputs" (array, required) A json array of json objects
[
{
"txid":"id", (string, required) The transaction id
"vout":n, (numeric, required) The output number
"sequence":n (numeric, optional) The sequence number
}
,...
]
2. "outputs" (array, required) a json array with outputs (key-value pairs)
[
{
"address": x.xxx, (obj, optional) A key-value pair. The key (string) is the bitcoin address, the value (float or string) is the amount in BTC
},
{
"data": "hex" (obj, optional) A key-value pair. The key must be "data", the value is hex encoded data
}
,... More key-value pairs of the above form. For compatibility reasons, a dictionary, which holds the key-value pairs directly, is also
accepted as second parameter.
]
3. locktime (numeric, optional, default=0) Raw locktime. Non-0 value also locktime-activates inputs
4. replaceable (boolean, optional, default=false) 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:
"psbt" (string) The resulting raw transaction (base64-encoded string)
Examples:
> bitcoin-cli createpsbt "[{\"txid\":\"myid\",\"vout\":0}]" "[{\"data\":\"00010203\"}]"
