fundrawtransaction - select input transaction with minimum confirmations #14542

when using to fundrawtransaction, how to select input transaction with minimum confirmations option ? @jonasschnelli what's default option for funded when select inputs ?

I don't understand the 2nd question.

As for the 1st, that is not possible. Why would you want to do that?

If the fundrawtransaction method selects input (1 confirmation tx), and what happens if the non-valid chain breaks ?

I guess with the createrawtransaction method, 6 confirmations txs can be selected, why can't this selection be made with the fundrawtransaction method ? @promag

It's not that simple, the coin selection algorithm takes into account several aspects, especially if an input is a transaction created by the wallet and the corresponding depth. AFAIK you can't override the minimum input depth.

So, in the coin selection algorithm, only the coin amount of UTXO are paid attention ? Is algorithm also taken care of the number of confirmations that received ?

I think it's totally reasonable to add an option to fundrawtransaction and walletcreatefundedpsbt to restrict coin selection to outputs with at least a certain number of confirmations.

I've been working on adding a minconf option to fundrawtransaction and walletcreatefundedpsbt. I can open a PR for this if this is still something people would find useful?
