Arbitrum has unveiled Fast Feed, a feature designed to show executed transactions more quickly and improve transaction visibility on its Layer-2 network. The rollout also includes Priority Gas Auctions, which let users compete through fees for earlier transaction ordering and faster execution. Arbitrum previously used Timeboost, which provided a fixed 200-millisecond head start, while the newer system uses dynamic fee-based priority. Robinhood Chain, launched in July and currently using first-come, first-served sequencing, is evaluating Priority Gas Auctions. The development comes as decentralized finance continues to prioritize transaction speed and efficiency, while broader crypto markets show mixed momentum.
