Every action (trades, bets, leverage, ect) in your Supa feed can be replicated with your Coinbase Smart Wallet with one click (⚡️).
Users who replicate your actions pay a small fee (0.25%) to your CB Smart Wallet. But this is only unlocked if you sign in once.
So if you're a good trader, you'll show up on the daily leaderboard and people will copy your trades. If they use the app to copy those trades (it's the easiest), then you'll get a fee.
TL;DR: Every action in Supa has a built-in referral fee for the original user.
