I am unable to spend from my offline cold storage, I can see the coins as available on the watch-only wallet. Using the transfer command, I am able to generate an unsigned transaction file.

This file is then signed using my offline wallet, followed by moving my signed transaction file to the watch-only online wallet.

When I submit the transfer, I am getting an error, "verification failed", from monerod.

Any ideas?

    did you import all the outputs into the cold wallet before generating the TX? did you already spend something from that cold wallet? Are you using the latest 0.10.1 software?

  • Yes the cold wallet is fully updated with outputs and nothing has ever been spent from it as of yet.... yes 0.10.1

    @riifella can your post an answer to your own question detailing how the mixin selection was related to the problem? This might also be a good issue to raise on GitHub

    Possibly you just double spent some outputs, and the last tx randomly selected outouts which were yet unspent, so it worked.

Based on the comments, it sounds like two transactions were attempted near each other. This should work in normal circumstances, but being on a (now) outdated Monero version could have caused issues.
