If/when you succeed in attaching both sending and receiving wallets horse and gun emojis will appear next to your nym.

If enables all other users of the platform to verify that you have attached LN wallets to enable maximising your use of LN here on SNs.

Once attaching your sending and receiving wallets is successfully done then as many as technically possible of your transactions here on Stacker News will be automatically made P2P via the LN in sats.

Because some participants have not attached wallets there are CC shitcoins circulating and so sometimes when people zap you with them you and the SNs algorithm will use them by passing them on to their next victim.

But once you have successfully attached wallets you will have done all that can be done to maximise your support of the LN and SNs sats denominated V4V P2P economy.

There are guides on how to attach both sending and receiving wallets.
One of the easiest wallets to attach is coinos but others also work.

As you can see from the SNs homepage the vast majority of regular participants on SNs have already attached wallets.

Your post suggests you have a very good understanding of the technical aspects of BTC/LN so attaching wallets should be a breeze.

Looking forward to seeing you join the vast majority of participants!
