Initializing the QRL App​

Before you can use the QRL Ledger Nano App, it must first be initialized. The initialization process will generate an XMSS tree on your Ledger Nano device, which is a unique aspect of the QRL Network's signature scheme. This process only has to be completed once on your Ledger Nano device. Please allow up to 45 minutes for this process to complete for each tree.

To initialize your Ledger Nano device for use with the QRL App, follow these instructions:

  1. Make sure your Ledger Nano device is Connected and Unlocked.
  2. Open the QRL app on your Ledger Nano
  3. Your Ledger Nano device will show QRL (Tree 1) not ready.
  4. Scroll down and press both buttons on the Init Tree menu option.
  5. Your Ledger Nano device will show QRL (Tree 1) keygen: 001/256. This will slowly progress until all 256 keys have been generated.
  6. When this process has completed, your Ledger Nano device will show QRL (Tree 1) READY rem:256 - indicating your device has finished generating tree 1 OTS keys, and you have 256 OTS Keys remaining in this Tree.
  7. Scroll down in the menu and chose Switch Tree with both buttons. You will now see QRL (Tree 2) Not Ready
  8. Initialize Tree 2 following the same steps above. Again this process will take about 45 minuets to complete.
