# Aster Open Standards

**Overview**

AOS (Aster Open Standards) is the standard layer for open finance on Aster, governed on-chain by validators.

Each AOS defines the rules for one financial domain, such as listing, trading, or asset management, so eligible participants can access it through a transparent and standardized process. Once a standard is live, participants can review the criteria, follow the applicable process, and apply to go live. 

This is how Aster expands its financial infrastructure, through a set of open, auditable standards that any project, builder, or operator can use to bring new financial activity on-chain.

***

**How AOS Works**

Each standard follows the same governance model:

1. Published rules — Every AOS defines its eligibility criteria, access mechanism, operating requirements, and applicable review process in a public specification.
2. On-chain enforcement — Access is gated by on-chain actions (fees, staking, or both), not by discretionary approval.
3. Validator governance — Where required by the standard, applications are reviewed through on-chain validator votes, rather than being decided by the Aster team unilaterally.
4. Operator accountability — Once live, the operator — whether a token project or a perpetual issuer — must operate within the published rules.

The result is a system where Aster publishes the standards, validators govern where applicable, and eligible participants can access each domain under transparent rules.

**Current Standards**

| Standard  | Domain                             | Access Mechanism                                          |
| --------- | ---------------------------------- | --------------------------------------------------------- |
| **AOS-1** | Spot Listing                       | One-time 50,000 USDT listing fee + validatorvote          |
| **AOS-2** | Perpetual Listing– **Coming Soon** | Stake **1,000,000 $ASTER** (4-year lock) + validator vote |

Each standard opens a distinct financial domain on Aster:

AOS-1 ：Spot Listing brings new tokens to Aster's spot markets. Projects that qualify through Binance Alpha or Binance Spot listing can apply through a self-service flow, pay a one-time fee, and go live upon passing the validator vote. The fee flows directly into the $ASTER buyback.

AOS-2 ：Perpetual Listing opens Aster's perpetual markets to any qualifying project. By staking 1,000,000 $ASTER for four years, a project demonstrates long-term commitment to the market. The market launches after validator approval and risk parameter configuration, with a designated Market Maker providing liquidity from day one.

**Why On-Chain Governance**

Listing decisions and certain market actions carry financial consequences.Placing them under on-chain validator governance rather than team discretion creates three properties that matter for an open financial system:

**Predictability** — The rules are published in advance. Any participant can know what is required to access each domain.

**Credible neutrality** — Validators vote on applications based on published criteria. For standards requiring a validator vote, no single team or entity can unilaterally approve an application.

**Auditability** — Every application, vote, and configuration change is on-chain and independently verifiable. Operators, users, and the broader ecosystem can inspect the record at any time.

***

**What Comes Next**

AOS is a living standard. As Aster's ecosystem grows, new standards can be proposed and ratified through governance — each one opening a new financial domain to permissionless access under validator oversight.

The architecture is designed to expand: every new AOS is a new surface for builders, projects, and operators to participate in Aster's open financial system on equal, published terms.
