Kept my ADA safe on Daedalus since early this year, until recently the sync failed and I had to re-install the app.
However, after restoring my wallet through the 12-phrases backup, my balance has been showing 0 with no transactions at all. These are the steps I’ve taken:
Deleted folder and installed latest version.
Removed wallet and re-imported it.
Installed Daedalus on a new PC and imported the wallet.
Checked the explorer, the address sent from Binance showed the correct amount, 1 transaction total. On Daedalus however, previously used address didn’t show up.
Happened to me twice while importing my wallet to different PC, as it turned out in my case, I got 1 word wrong. the moment I got all the 12 phrases right it displayed my correct balance and the correct wallet address.
There’s something strange going on when you mentioned that.
Out of the 12 words I wrote down in order and kept, 1 of them, specifically the 9th didn’t register (or didn’t exist) so I had to choose another and it worked. But that led to 0 balance which is very confusing.
You need to write the words in order but maybe just like in my case you’ve written that “one letter” of that one word wrong. examples “aim” instead of “air” or “price” instead of “prize” or “oven” instead of “over” or maybe you forgot there is “d” in the end like “used” instead of “use”.
It’s obviously too late in this case, but a backup on the same drive is not really a backup, it should always be on different media. Drive failure is I believe the most common cause of data loss.
