**Aster has launched chase orders**, a new order type that automatically adjusts limit order prices to track the best bid or ask. **Key features:** - Orders update automatically to stay competitive without manual repricing - All chase orders are post-only, ensuring maker fills only - Zero maker fees apply to all chase order executions - If a price update would cross the spread (becoming a taker order), the engine automatically retries at the current best bid/ask instead **Technical implementation:** Aster is the first decentralized exchange to build chase orders natively into its matching engine, with all operations verifiable on Aster Chain. This feature allows traders to maintain optimal positioning in the order book while avoiding taker fees entirely.
