Title: createwallet "disableprivatekeys" Post by: x3m on June 13, 2020, 10:40:15 PM The purpose of this feature as explained here: https://github.com/bitcoin/bitcoin/pull/9662 (https://github.com/bitcoin/bitcoin/pull/9662) should be to ensure no mix between hot and cold keys but honestly I don't understand the use case.
What I've used instead, is the watch-only deterministic wallet created using a Master Public Key as explained here: https://bitcoinelectrum.com/creating-a-watch-only-wallet/ (https://bitcoinelectrum.com/creating-a-watch-only-wallet/). Can anyone explain how to use createwallet "disableprivatekeys" together with fundrawtransaction? Title: Re: createwallet "disableprivatekeys" Post by: achow101 on June 14, 2020, 01:45:15 AM The description in the PR isn't saying that disableprivatekeys wallets should be used with fundrawtransaction, but rather that they can be because fundrawtransaction allows setting a custom change address.

Could you please make an example on how to manage creating transactions on a cold wallet and broadcasting through a hot wallet created with disableprivatekeys set?

Note that this uses another feature that allows for pubkeys to be imported into the keypool of wallets with private keys disabled.

I've just tested this workflow using Bitcoin Core (TestNet) 0.20.0 and a Ledger Nano S. I installed the "HWI" Python module (and libusb) and was able to successfully create a "watching only" wallet within Bitcoin Core. I funded it with 0.1 tBTC and was then able to create the PSBT, finalise it and send it using HWI, my Ledger Nano S and bitcoin-cli.I did get an "Unverified Inputs" warning on the Ledger device when signing the transaction, but I was able to "ignore" that error and continue. @achow101, is that warning possibly due to the fact that the transaction that created the UTXO I was spending only had 1 confirmation when I was attempting to sign the transaction? ???

No, that's because of a recent update to the Ledger Bitcoin App that requires software to provide more UTXO data. There's a PR to fix that (along with a bunch of other related issues in other devices).@achow101, is that warning possibly due to the fact that the transaction that created the UTXO I was spending only had 1 confirmation when I was attempting to sign the transaction? ??? |
