Can't submit (allegedly) correct transaction

Question

Ok, here we go. First, the balance:

$ cardano-cli query utxo --address addr1vx9z6r6pv5g8aprprvjj2jhamsj4szr6j502fk7wkzq6a3sx0736n --mainnet
                           TxHash                                 TxIx        Amount
--------------------------------------------------------------------------------------
6adeb2bb5e294bcaf4b3aaf555b121e20cfb1c69631d2a8ba64c6b935201e9de     0        4579280 lovelace + TxOutDatumNone

checking that my vkey is the correct one:

$ cardano-cli address build --payment-verification-key-file payment.vkey --mainnet
addr1vx9z6r6pv5g8aprprvjj2jhamsj4szr6j502fk7wkzq6a3sx0736n

building transaction:

$ txin=6adeb2bb5e294bcaf4b3aaf555b121e20cfb1c69631d2a8ba64c6b935201e9de
$ txix=0
$ utxo=4579280
cardano-cli transaction build-raw --tx-in "$txin#$txix" --tx-out "$(cat ../coldwallet.addr)+0" --invalid-hereafter 0 --fee 0 --out-file test.draft

Calculating fee, expiry & rebuilding transaction:

$ fee=( $(cardano-cli transaction calculate-min-fee --tx-body-file test.draft --tx-in-count 1 --tx-out-count 1 --witness-count 1 --byron-witness-count 0 --mainnet --protocol-params-file ../protocol.json) )
$ slot=$(( $(cardano-cli query tip --mainnet | jq '.slot')+3600 ))
$ cardano-cli transaction build-raw --tx-in "$txin#$txix" --tx-out "$(cat ../coldwallet.addr)+$(($utxo-$fee))" --invalid-hereafter $slot --fee ${fee[0]} --out-file test.draft

signing, checking and submitting it:

$ cardano-cli transaction sign --tx-body-file test.draft --signing-key-file payment.skey --mainnet --out-file signed.tx
$ cardano-cli transaction view --tx-file signed.tx

I've tried everything within my knowledge to fix that, but i couldn't. I've tried to generate the vkey from my skey again, using:

$ cardano-cli key verification-key --signing-key-file key.skey --verification-key-file key.vkey

but it generates a different vkey, which gives me a different address.

Any ideas?

Answer 1

I'm going to answer you the same thing I answered on the cardano forum: if the last command gives you a different vkey. which gives you a different address, it means you have the signing key from a different address, not from the address where the ADA is.
