Your seed is the most important part of your Sia node because it controls access to your wallet and files. You need to keep it safe, but there are a few tools you have available to find or fix your Sia seed.
These commands can be used directly in siac. In Sia-UI, open the Terminal from the toolbar on the top of the app.
If Sia is already unlocked
You might use a custom password to access Sia. If you do, you don't often type your seed in and you may need a refresher on what it is.
Unlock your wallet and open the Terminal. Type wallet seeds.
siac utils has a couple of commands that can help you troubleshoot your seed.
verify-seed
This will attempt to diagnose an issue with your seed.
Usage./siac utils verify-seed
You'll be asked to provide your seed, at which point Sia will provide one of the following outputs:
Success
No issues detected with your seed - the seed you provided meets all the requirements for a Sia seed, and should be valid
Failure
invalid formatting - usually indicative of extra spaces in between words or at the end, or no spaces between words
seed is not valid: must be 28 or 29 words - your seed is too short or too long
seed is not valid: all words must be lowercase - there is a capital letter somewhere in your seed
seed is not valid: illegal character - you have something other than a letter in your seed
bruteforce-seed
If your seed is missing one word, this will attempt to figure out the missing word. This can also be used to check a word you're not sure about, by deleting it and then running this.
Usage./siac utils bruteforce-seed
You'll be asked to provide your partial seed, and Sia will get to work. It may take a couple of minutes to complete. Sia will provide one of the following outputs:
Success
Found valid seed! The missing word was <word>.
Sia will then print the entire correct seed for you to store safely.
Failure
No valid seed - the utility was unable to find your missing word
Expected 27 or 28 words in partial seed, got <n> - the partial seed you provided was missing more than one word
Couldn't read seed - the partial seed you provided was invalid in other ways
