# wstUsdcLite

## Overview

`wstUsdcLite` is a minimal implementation of `wstUsdc` that will be deployed on all blockchains except for Arbitrum. If users on another chain need to deposit and redeem they must either bridge back to Arbitrum or interact with one of our partnered chain abstraction providers. (More details on this to come).
