Introduction

Brighter is a yield engine built on Lighter Protocol, connecting stablecoin holders and LIT holders through an interconnected dual-pool system.

The Problems We Solve

For Stablecoin Holders

• Want LLP yields, but must stake LIT to unlock capacity (1 LIT = 10 USD)

• Fragmented experience across multiple interfaces

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:

Pool	Users	Action	Earn
sUSDb Vault	Stablecoin Holders	Deposit USDC	LLP yield + Brighter Points
LIT Staking Pool	LIT Holders	Stake LIT	Pool Fee share + Lighter rewards
