PANews June 26 news – Aster has officially launched AOS-1, the first module of Aster Open Standards (AOS), enabling permissionless spot token listings and allowing new tokens to access the Aster Spot market more conveniently. To enhance trading depth and liquidity, Aster simultaneously reduced the maker fee for AOS-1 trading pairs to -0.25 bps, meaning market makers receive a fee rebate upon maker order execution, forming a negative-fee incentive mechanism.

Aster CEO Leonard stated that AOS is designed to deeply integrate self-custody and permissionless deployment at the protocol level, while AOS-1 establishes a standardized framework for open spot listings and attracts more liquidity providers to participate in on-chain market making through the rebate mechanism.
