# ArcX > ArcX wraps perp DEX strategies into a vault token that earns yield and credits for supported reward programs. Split into ST and EPT for isolated exposure. ## Docs - [Credit Mathematics](https://docs.arcx.trade/deep-dives/credit-mathematics.md): How credits determine each holder's share of CreditTokens across periods, using capital multiplied by time. - [EPT Pricing](https://docs.arcx.trade/deep-dives/ept-pricing.md): How ST and EPT are priced, why the returns frame matters, and what drives the ST discount. - [Orderbook Mechanics](https://docs.arcx.trade/deep-dives/orderbook-mechanics.md): APR pricing, token sizing, matching rules, and market-order mechanics for the ArcX orderbook. - [ArcX Documentation](https://docs.arcx.trade/index.md): 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. - [Audits](https://docs.arcx.trade/learn/audits.md): ArcX smart-contract audit reports. - [CreditToken](https://docs.arcx.trade/learn/credit-token.md): The token generated from accrued credits and used for reward distribution. - [Expected Points Token (EPT)](https://docs.arcx.trade/learn/expected-points-token.md): The rewards side of a series.

Every series has a fixed maturity date and its own ST and EPT tokens. - [Strategy Token (ST)](https://docs.arcx.trade/learn/strategy-token.md): The principal + yield side of a series. Give up the rewards side and redeem back into vToken at maturity. - [Trust Model & Security](https://docs.arcx.trade/learn/trust-model-and-security.md): What is on-chain today, where ArcX still relies on off-chain components, and what risks users are actually taking. - [User Guide](https://docs.arcx.trade/learn/user-guide.md): Step-by-step: deposit for vTokens, buy EPT or ST on the orderbook, withdraw, and manage positions through series maturity. - [vToken](https://docs.arcx.trade/learn/vtoken.md): The base vault share. Deposit USDC, earn yield, and accrue credits for supported reward programs. - [Restricted Jurisdictions](https://docs.arcx.trade/legal/restricted-jurisdictions.md): Jurisdictions where ArcX transaction access is restricted. - [Risk Disclosure](https://docs.arcx.trade/legal/risk-disclosure.md): Key risks for vToken, ST, EPT, CreditTokens, market makers, rewards, and order execution. - [Terms of Use](https://docs.arcx.trade/legal/terms-of-use.md): Terms for accessing ArcX documentation, interfaces, and protocol-related information. - [Quick Reference](https://docs.arcx.trade/reference/glossary-and-reference.md): Token summary, key equations, fees, and series mechanics at a glance. ## OpenAPI Specs - [openapi](https://docs.arcx.trade/api-reference/openapi.json)
