# Does Questflow Support Lighter?

**Short answer:** Lighter is on Questflow’s execution coverage map as a perp venue. The harness is built to compare order-book quality, fees, and fill — and use Lighter when it is the better route, not because it is the only logo on the home screen.

## Why a second perp venue exists

A finance agent that can only fire on one book is not a harness. Execution context includes: best venue, slippage, fees, order type. Lighter is part of that comparison set alongside Hyperliquid.
