# ArcX Documentation

> ArcX wraps perp DEX strategies into a vault token that earns yield and credits for supported reward programs. Buy ST or EPT for isolated exposure.

Deposit USDC into a vault, receive a **vToken** — a vault share that earns yield and accrues credits for supported reward programs. Hold it for the combined exposure, or buy **ST** (principal + yield) or **EPT** (rewards side) on the orderbook to concentrate into the side you want.

Reward buyers buy EPT for rewards-side exposure. Yield seekers buy discounted ST for principal + yield exposure. Or just hold vToken and earn both.
