Create a signing key from an address in Daedalus wallet (Resolved)

#1

To all you smart people out there I have a question about using addresses from a wallet in cardano-cli that I have been struggling with and that I think will be helpful to others as I have found a few answers that are not clear or do not solve this issue:

This is all on testnet:

Summary

I would like to manage my addresses in a wallet like Daedalus but I would like to also use the cardano-cli on these addresses especially for my stake pool.
I believe that it’s not possible to add addresses created using the cardano-cli to Daedalus or Yoroi but it is possible to generate the keys using cardano-address using the recovery phrase and then to use cardano-cli to generate the signing key.

I have managed to use cardano-address to generate the payment address and it matches with my 0/0 address in Daedalus. I have created the signing key but when I try and submit a transaction I get the error MissingVKeyWitnessesUTXOW so I know I am missing a step.

Steps taken

  1. Generate a root private key (testnet-root.xsk)
    ./cardano-address key from-recovery-phrase Shelley < phrase-testnet.prv > testnet-root.xsk

  2. Generate a payment verification key (testnet-addr.xvk)
    ./cardano-address key child 1852H/1815H/0H/0/0 < testnet-root.xsk | ./cardano-address key public --with-chain-code > testnet-addr.xvk

  3. Generate a payment address from a payment key (testnet-payment.addr)
    ./cardano-address address payment --network-tag testnet < testnet-addr.xvk > testnet-payment.addr

  4. Stake key
    ./cardano-address key child 1852H/1815H/0H/2/0 < testnet-root.xsk | ./cardano-address key public --with-chain-code > testnet-stake.xvk

  5. Delegate payment address (Note this address matches the address in Daedalus)
    ./cardano-address address delegation $(cat testnet-stake.xvk) < testnet-payment.addr > payment-delegated.addr

Now I use the caredano-cli to generate the signing key. This is where I think I am going wrong

cardano-cli key convert-cardano-address-key --shelley-payment-key --signing-key-file /var/cardano/local/testnet-root.xsk --out-file /var/cardano/local/testnet-address.skey

Error:

So now when I create my transaction using
payment-delegated.addr - (Source account address)
testnet-address.skey - (Key to sign the transaction)

I get the following error

Command failed: transaction submit  Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraMary (ApplyTxError [UtxowFailure (MissingVKeyWitnessesUTXOW (WitHashes (fromList [KeyHash "86a340294178774a3f7420e46fe08739d8669e9a465982aa8edc9c77"]))),UtxowFailure (UtxoFailure (OutsideValidityIntervalUTxO (ValidityInterval {invalidBefore = SNothing, invalidHereafter = SJust (SlotNo 30696916)}) (SlotNo 30760233)))])

You would probably want to us a HW wallet (i.e. Ledger) for that. You can connect your Ledger to a variety of Cardano clients and can also use cardano-hw-cli to manage your pool.

One needs to generate the signing key from the child private key 1852H/1815H/0H/0/0, not from the root private key.

Here is one recipe that shows creating the signing key for the child.

Thanks to tomdx and bwbush I have managed to find the solution:

Instead of using cardano-address I used cardano-wallet

The issue from my examples above was that I was signing my transaction with the seed/root key and not the payment address signing key.

So here are the steps:

Install cardano-wallet Releases · input-output-hk/cardano-wallet · GitHub

  1. Generate the ROOT private key from the recovery phrase
cat phrase-testnet.prv | ~/cardano-wallet/cardano-wallet key from-recovery-phrase Shelley > tn.root.prv
  1. Generate the private and public Payment keys using the root private key for the first address
~/cardano-wallet/cardano-wallet key child 1852H/1815H/0H/0/0 < tn.root.prv > tn.payment-0.prv
~/cardano-wallet/cardano-wallet key public --without-chain-code < tn.payment-0.prv > tn.payment-0.pub
  1. (The missing part) Generate the signing key for the payment address
~/cardano-wallet/cardano-cli key convert-cardano-address-key --shelley-payment-key \
                                            --signing-key-file tn.payment-0.prv \
                                            --out-file tn.payment-0.skey

The remainder of the keys can be created by incrementing the last digit of the deviation path. E.g 1852H/1815H/0H/0/0 and 1852H/1815H/0H/1/0

  1. Generate the stake keys. The process is similar to above
~/cardano-wallet/cardano-wallet key child 1852H/1815H/0H/2/0    < tn.root.prv  > tn.stake.prv
~/cardano-wallet/cardano-wallet key public --without-chain-code < tn.stake.prv > tn.stake.pub

~/cardano-wallet/cardano-cli key convert-cardano-address-key --shelley-payment-key \
                                            --signing-key-file tn.stake.prv \
                                            --out-file tn.stake.skey
~/cardano-wallet/cardano-cli key verification-key --signing-key-file tn.stake.skey \
                                 --verification-key-file tn.stake.vkey
  1. Generate the addresses by computing the payment key and the stake key
cardano-cli address build --testnet-magic 1097911063 \
                          --payment-verification-key $(cat tn.payment-0.pub) \
                          --stake-verification-key $(cat tn.stake.pub) \
                          --out-file /var/cardano/local/tn.payment-0.address

If you cat this address tn.payment-0.address it should match your address in your wallet.

  1. Now you can generate your payment using:

Source payment address: tn.payment-0.address
Source payment signing key: tn.payment-0.skey

My advice, figure this all out on testnet.
