[Aster Launches AOS-1 Open Standard, Spot Maker Rebate 0.25bps] Aster has officially launched the first module of its open standard AOS (Aster Open Standards), AOS-1, which supports permissionless spot token listings, allowing new tokens to integrate into the Aster Spot market more conveniently. To enhance trading depth and liquidity, Aster has simultaneously reduced the maker fee for AOS-1 trading pairs to -0.25bps, meaning market makers will receive a rebate after their orders are filled, creating a negative fee incentive mechanism. Aster CEO Leonard stated that AOS aims to deeply integrate self-custody and permissionless deployment at the protocol layer, with AOS-1 establishing a standardized framework for open spot token listings while attracting more liquidity providers to participate in on-chain market making through the rebate mechanism.
