Cardano Daedalus ITN testnet: how to fix syncing issues


First of all you must have the latest version which at the time of our writing is 2.0.1-ITN1. You can see the version at the top when opening Daedalus. Check official website for latest version of testnet ITN Daedalus.

Switch client solution #1

You can temporary switch to Yoroi where you can restore your Daedalus wallet with 15-word recovery phrase and delegate from there. It is an official wallet from Emurgo which is one of 3 entities that run Cardano network. See our Yoroi tutorial on how to setup that.

Syncing issues Daedalus solution #1

If Daedalus is stuck on the sync screen there is a high chance we must change the trusted peer list to which the wallet connects to. This is especially true for version 2.0.1-ITN1.

  1. First close Daedalus!
  • Right click the Daedalus — Rewards v1 shortcut and click Open file location
Right click -> “Open file location”
  • Search on the drive you installed the Daedalus wallet. Click the one with the folder icon.
Search drive
Daedalus folder with “jormungandr-config“ file
Edit with notepad
Scroll down.
Click into the input, copy everything
Paste into the “yaml input” field, copy from “json output” field
Compare your file with this reference image.
Should write Valid JSON if everything is OK

Syncing issues Daedalus solution #2

Other thing you can try is to upgrade two files that wallet is using which should dramatically shorten syncing times and add some stability .

jcli, jormungandr files
Backup rename jcli, jormungandr
Download “” for Windows OS
Extract jcli and jormungandr to “Daedalus — Rewards V1" folder


If your wallet still doesn’t start syncing you should try to restart it a couple of times. Remember to leave it running for half and hour to an hour. If still nothing you should re-copy peers from after some time has passed. The list is being updated regularly.
