Currently, SparkSat's seed phrase can be used on Xverse or Luminex.
When using a new wallet in compatibility mode
If you're using an Xverse or Luminex compatible wallet, it's very simple - just import the seed phrase. You'll see that the Spark address displayed by default on the target platform matches the one on SparkSat.
When using a wallet without compatibility mode.
In Xverse, import the same seed phrase, then click on Account1 at the top.
Click on "+ Generate account", then select Account 2.
