Ok thank you. And normally this should work to sign a PBST offline without any access to txindex or the mempool, similarly to signrawtransaction?
As long as the PSBT is updated with all of the necessary data.

There is a proposal for a descriptorprocesspsbt RPC that would do signing.

just want to provide the PSBT and the private key as an input to sign the transaction...
You mean a signrawtransactionwithkey type RPC call for psbt ? I guess, we don't have any for now. walletprocesspsbt is the only way, unfortunately.Yes exactly, it would be very useful for offline signature of PSBTs. Is there any plan to add such functionality? I am right that as opposed to an unsigned raw transaction, a PSBT contains all the required information to sign it offline (excluding the private key)? Thanks!

Sry, not sure! December 10, 2022, 11:49:04 AM
There is no "processpsbtwithkey" function?
No such RPC. Try these:
Code:
walletprocesspsbt
Code:
finalizepsbt
Refer : PSBT Howto for Bitcoin Core.

Hi,
I am trying to move from creating a transaction using createrawtransaction on a networked computer and sigining it using signrawtransactionwithkey on a non-connected computer to using psbts. The createpsbt function seems to work fine, but I don't know how I can sign it in the other system using the key? There is no "processpsbtwithkey" function?
