WalletWasabi: v1.1.12 Unable to sign with usb-connected ColdCard
General Description
Even though it is not a best security practice, the other issues reported with Trezor and Ledger HW-devices pushed me to try and use the ColdCard over USB to see if that still works with the latest firmware. Conclusion, it does not! With a similar error as the other hardware wallet gave when trying to sign the testnet txs. Actually no prompt to sign a txs was shown on the ColdCard at all, in contrast to the LedgerNanoS test #3931 edit: The prompt on ColdCard shows up ~2 minutes too late.
How To Reproduce?
- Go to ‘Send’
- Make a test txs with selected coins and receiving address
- Click on ‘Send Transaction’
- Wait for hardware wallet to respond
- See error

I am closing it. Feel free to reopen if occurs again. By the way, I had similar problems with Ledger and turned out the USB cable was just not “compatible”. As soon I as replaced with another one all issues went away.
After a long wait and machine reboot, the 2 UTXO consolidation worked properly! Also confirmed 5 UTXO can be consolidated without issues:
Perhaps this issue is simply related to some USB bitrate setting on my PC, causing very lengthy communication times once in a while… otherwise I have no good explanation for this behaviour.
Tested again with 1.1.12rc2, selected both 5 and 2 UTXO to try:
With 5 UTXO I did not see any prompt on the Coldcard (via USB) and with 2 UTXO selected I did see the prompt.
Here I signed/accepted, but Wasabi did not properly receive/broadcast the transaction 😢
@molnard @MaxHillebrand Update 2: I’ve now been able to successfully sign over USB, after updating dotnet Core to the latest version and rebooting my machine!
Perhaps something funny was going on with the USB interface when connecting different hardware wallets during the same session, don’t know for sure. Probably safe to say Wasabi Wallet rc1.1.12 does USB-signing correct now too for me.
Waiting time was just a few seconds, not 5 minutes, before the ColdCard displayed the TXs details to sign.
What I noticed now, trying to reproduce the error, is that the ColdCard gives me the ‘OK to Send?’ message about ~2 minutes after the time-out of 3 minutes for sending a TXs in WasabiWallet. After signing on the ColdCard the transaction does not get communicated with WasabiWallet anymore, also after clicking the Send Transaction button in the Send tab again. I have the idea that there is a big delay, maybe because of a big txs, or because HWI is not responsive enough with detecting and forwarding the txs to sign.
