Arbitrum Replaces Timeboost With Per-Transaction Priority Auctions

The shift from Timeboost to per-transaction priority auctions changes who captures ordering value on Arbitrum, and the 97/3 split toward the DAO and Developer Guild makes that value a recurring treasury line rather than an operator or searcher margin. That matters for projects and traders whose economics depend on latency and inclusion, since priority now gets priced per transaction instead of through a bundled subscription. Whether the auction format actually deepens demand for priority, and how Fast Feed subscriptions coexist with it, is the open question to watch.
