Not A Token is a Rewards System

Farcaster users currently earn Not A Token in 4 ways; many more on the way:

1️⃣ Just from casting. Every cast automatically earns Not A Token based on who engages with it. TLDR: post stuff people like and automatically earn points; no tips required

2️⃣ Just from replying: Every reply is also eligible for Not A Token - because sometimes the banger is in the replies 

Check the earnings of any cast or reply with this Cast Action

3️⃣ Launching high quality frames. Airstack rewards 25 Not A Token for every unique Farcaster user who uses any Frame that we can track with Airstack's free Frames Validator API

4️⃣ by swapping tokens in Airstack's swap frame
