Introduction

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

The Problems We Solve

For Stablecoin Holders

• Want LLP (Lighter Liquidity Provider) 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	LIT Pool Yield Share + Lighter rewards

How They Connect

1

LIT Holders stake LIT

Creates deposit capacity.

2

Stablecoin Holders deposit USDC

Uses capacity; funds go to LLP.

3

LLP generates yield

Yield comes from trading fees.

4

Yield is distributed

Stablecoin holders get net yield; LIT holders get Yield Share.

Tokens

Token	What It Is	Who Uses It
USDC	Stablecoin you deposit	Stablecoin Holders
sUSDb	Yield-bearing token received when depositing. Value increases as LLP generates returns.	Stablecoin Holders
LIT	Lighter's token. Stake on Brighter to earn LLP Yield Share.	LIT Holders

Key Features

• Dual-Pool Yield Engine — Two pools that match stablecoin depositors with LIT capacity providers.

• Dynamic Yield Share Rate — Adjusts based on utilization (0–80%) to balance supply and demand. All yield share is distributed to the LIT Staking Pool.

• Brighter Points — Earn points based on your participation on Brighter.
