## Overview

> Universes Rollups (ROLLS) is a novel public good mechanism for settling intents across chains. This mechanism:
>
> 1. Allows fillers to *socialize* the costs of rebalancing by netting off settlements against other fillers and users in the network.
> 2. Acts as a programmable layer for fillers or users to build and utilize any number of mechanisms for rebalancing/settling funds (e.g. by plugging into any messaging mechanism, liquidity pool, CEX, etc.)
> 3. Enables permissionless expansion to new chains and rollups, making it possible for any application on any chain to onboard users from any other chain.
