Aster has introduced its Aster Open Standards Phase 2 (AOS-2) framework, expanding its open listing process to include perpetual futures contracts. This new phase requires eligible projects to stake 1 million ASTER tokens for a duration of four years before they can seek approval through an on-chain validator vote.
The AOS-2 framework allows projects to submit proposals for launching perpetual markets. The process involves token staking, a vote by validators on the Aster Chain, risk configuration by Aster's team, and market setup. Aster aims for a T+1 listing timeline following approval and configuration.
Validators review proposals and record their decisions on the Aster Chain. Projects that are not approved by the validators receive their full ASTER stake back. Successful applicants must also ensure market maker support and complete risk configuration, with Aster's risk system determining leverage and other trading parameters.
AOS-2 builds upon AOS-1, which introduced Aster's open listing structure for spot markets. The expansion to perpetual futures comes as decentralized exchanges (DEXs) have seen a significant increase in their share of open interest in this market. CoinGecko data indicates perpetual DEXs' share of open interest grew from 3.5% in early 2025 to 13.6% in early 2026, with total open interest across leading perpetual DEXs rising from $1.19 billion to $14.99 billion between early 2024 and January 2026.
