Arbitrum governance is weighing a proposal that could turn transaction-ordering data into a paid network product.
A new Constitutional AIP on the Arbitrum Governance Forum proposes creating the Fast Feed, a subscription-based data stream for Arbitrum One. The feed would give paying subscribers earlier access to updates on transactions, their relative ordering, and related metadata than they would receive through the regular public feed.
The proposal is technical, but the market angle is easy to understand. In high-speed DeFi, timing matters. Earlier visibility into ordered transaction flow can be valuable for market makers, MEV searchers, automated liquidity strategies, and latency-sensitive applications. Arbitrum is now considering whether that value should be packaged into a paid product whose revenue flows back to the ecosystem.
TL;DR
- Arbitrum is discussing a Constitutional AIP for a paid data product called Fast Feed.
- Fast Feed would provide earlier access to ordered transaction metadata on Arbitrum One.
- The proposal says the feed would not change transaction ordering, inclusion guarantees, or user fees.
- Subscription revenue would be split 97% to the ArbitrumDAO and 3% to the Arbitrum Developer Guild.
What Fast Feed Would Do
The proposal describes Fast Feed as a paid, authenticated stream exposed through a new sequencer endpoint. Subscribers would receive updates after transaction ordering has been determined by the sequencer and queued for execution, but before the same information is available through the standard public feed.
That distinction is central to the proposal’s defense. The AIP says Fast Feed should not introduce new forms of MEV, front-running, or sandwich attacks because it publishes read-only information after the sequencer has already determined the order. In other words, subscribers would see the ordered stream sooner, but they would not be able to use the feed to change that ordering.
The system would also include a payment contract on Arbitrum One. Users would pay for access and submit an API key hash, which the sequencer would cross-reference before allowing Fast Feed connections. The proposal says this paid model is partly intended to reduce denial-of-service risk and maintain reliability for teams that actually need the service.
Why Traders And Builders Care
For ordinary users, Fast Feed may sound distant from the simple act of swapping tokens or using a lending protocol. But for the infrastructure around DeFi, earlier visibility can matter a lot.
MEV searchers, proprietary automated market makers, and latency-sensitive protocols all compete around execution information. If they can see the ordered flow slightly earlier, they may be able to update strategies, manage inventory, or price liquidity more efficiently. The question is whether selling that visibility creates a fairer, more transparent system or whether it gives paying participants an informational edge.
The proposal argues that access would be open and permissionless because anyone willing to subscribe could use the feed. It also says Fast Feed would be ordering-neutral: it would not change transaction priority, inclusion guarantees, or the transaction fees users pay.
A New Revenue Stream For ArbitrumDAO
The economics are one of the more interesting parts of the AIP. Under the proposal, 97% of subscription revenue would go to the ArbitrumDAO, while 3% would go to the Arbitrum Developer Guild. That would turn sequencer-adjacent data access into a direct ecosystem revenue source.
This fits a wider trend across layer-2 networks. As scaling networks mature, they are no longer judged only by transaction count or total value locked. They also need sustainable revenue models, clear governance processes, and infrastructure that can support professional-grade trading activity.
Fast Feed has not passed, and the proposal should not be treated as final. It is in the governance discussion stage. But the debate is important because it shows where layer-2 economics may be heading: not just cheaper blockspace, but monetized access to specialized network data.
