Why do I see signature verification errors 50300 or 40000?

This guide explains why signing may fail with errors like 50300 or 40000. This usually happens when the ELLIPAL App and cold wallet are not fully synchronized.

Solution

1. Delete the account from the ELLIPAL App

   • Don’t worry, your assets are still safe on the blockchain

2. Re-import the account on the cold wallet

3. Reconnect the cold wallet to the ELLIPAL App

   • Re-sync the wallet by scanning the QR codes

4. Try the transaction again
