user120940: I wonder if you can help me.
I have my 17 word seed (yes 17 words) and my wallet crypto address and I can see my crypto on the blockchain under that address.
How do I restore my wallet with the above two things because my previous device failed and is dead.

user13866: There have been other questions about 17 word phrases. It may be possible that they are legacy recovery phrases from obsolete wallet software provided by the business blockchain.info (now blockchain.com). That business has a web page for wallet recovery using legacy phrases.

NOTE: If you have a 12 word recovery phrase from our HD wallet, please go to the HD wallet recovery page.

I would hate to put a recovery phrase into a website of some random business, but maybe you originally used that business for your wallet for some strange reason? If so, that may be useful.
