# Arbitrum One Surpasses 13 Million Priority-Fee Transactions By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/31540 Published: 2026-10-13T21:39:50.000Z Updated: 2026-10-13T21:39:50.000Z Section: Technology > The milestone points to continued activity on Ethereum’s layer-2 network as Arbitrum uses priority fees to support faster transaction processing. Arbitrum One has exceeded 13 million transactions involving priority fees, indicating continued activity on Ethereum’s layer-2 network and demand for faster transaction processing. Arbitrum is designed to increase Ethereum’s transaction throughput and reduce costs. Its priority-fee system lets users compete for earlier transaction ordering when network demand is high. The milestone follows Arbitrum One’s replacement of Timeboost with a Priority Gas Auction system on Sept. 24. The system divides each 250-millisecond block into two 125-millisecond rounds and ranks transactions by their priority fees. Transactions offering higher fees can be selected earlier within a round. Those arriving after a round starts wait for the next one, making transaction timing relevant to activities such as arbitrage and liquidations. The transaction count indicates substantial activity on Arbitrum One. The network’s priority-fee structure is described in [TokenPost’s earlier coverage of Arbitrum transaction ordering](). ## Links in this article - [TokenPost’s earlier coverage of Arbitrum transaction ordering](https://www.tokenpost.com/news/technology/29195)
