LOVE INDEX

STATUS: ACTIVE NETWORK: BASE L2
The Premise

the world's first cryptocurrency indexed by love, positivity, and doing good.

LefCoin's value is driven by the LOVE Index — a composite score measuring world sentiment across peace, charity, social mood, environment, wellness, and on-chain good spending. Positivity literally pays.

THE BELIEF

What If

LOVE HAD A PRICE?

Not a price tag on emotion — but a measurable, tradable reflection of the world's collective goodwill. What if every act of charity, every peace treaty, every community effort could amplify the value of something you hold?

The Mechanic

POSITIVITY PAYS

Every LefCoin transfer generates a 1% fee that flows into a rewards pool. The LOVE Index amplifies those rewards — at maximum positivity (1000), holders earn 2x. The world gets better, everyone profits. A positive feedback loop encoded in code.
