Introduction

Brighter is a yield engine built on top of Lighter Protocolarrow-up-right, connecting stablecoin holders and LIT holders through an interconnected dual-pool system.

The Problems We Solve

For Stablecoin Holders

For LIT Holders

  • LIT's capacity utility goes to waste without stablecoins to deposit

  • Missing potential earnings from unused capacity

The Dual-Pool System

Brighter solves this through two interconnected pools:
