Sure thing—here’s the quick lowdown.

@ (at‑sign)

- Used to mention a user or project account on social platforms (e.g., @plasma).

- Clickable, notifies the mentioned party, and links to their profile.

- Works in posts, comments, and chats across X, Binance Square, Discord, etc.

# (hashtag)

- Used to tag a topic or trend (e.g., #plasma).

- Turns the word into a searchable link that shows all posts with that tag.

- Helps with discoverability and community tracking.

$ (dollar sign)

- Used to tag a token or coin symbol (e.g., $XPL ).

- On many crypto platforms, it links to price charts, market data, or token pages.

- Not a mention or hashtag—just a financial ticker reference.

So, `@` = people/projects, `#` = topics, `$` = tokens.
