Why Arbitrum
Market quality is shaped in milliseconds
The closer your data and execution are to the market, the better your product can respond. Arbitrum gives teams clearer priority and earlier visibility into market activity.
A Familiar Way to Compete
Express what earlier ordering is worth with a familiar priority fee.
Earlier Visibility
See ordered activity sooner, giving pricing, risk, and execution systems more time to respond.
Everyday UX
Add priority for the moments that need it while everyday users continue transacting normally.
Straightforward by design
From visibility to action
Two practical tools for time-sensitive execution: earlier visibility into ordered activity and priority fee bidding.
Fast Feed
See ordered transaction activity sooner so your systems can monitor markets and react faster.
How it works
- Subscribe - your app or market infrastructure connects to Fast Feed.
- Receive ordered activity - see transaction data sooner after its order is determined.
- Benefit from a sharper UX - use fresher information for pricing, risk, or trading.
Priority Gas Auction
Compete for earlier transaction ordering with standard EVM priority fees.
How it works
- Spot the moment - your strategy identifies a time-sensitive transaction onchain.
- Set your priority - attach the priority fee that reflects what earlier execution is worth to you.
- Compete for position - higher priority fees compete for earlier ordering within each round.
Built for Time-sensitive Finance
Compete, monitor, and react
Not every transaction needs priority, and not every product needs the same data. Teams can focus on the moments and workflows that are important to them.
For searchers and arbitrageurs
Compete for earlier execution with a familiar mechanism.
Use Fast Feed to observe ordered flow sooner and identify opportunities that require a timely response. Then use priority fees to express what earlier execution is worth.
For pAMMs and DeFi protocols
See market activity sooner. Respond with greater control.
Use Fast Feed to monitor ordered transaction flow earlier across pricing, risk, liquidation, and execution workflows. When a market change requires a time-sensitive onchain response, use priority fees to compete for earlier ordering.
For Dedicated Blockchain Operators
Offer familiar priority mechanics and add a revenue lever.
Enable PGA to give your users a clear way to compete for transaction priority while also creating an additional source of revenue. Fast Feed can remain as a complementary service for participants that need earlier visibility into ordered activity.

Frequently Asked Questions
What teams need to know
Start with the service that addresses your immediate bottleneck. Product, technical, and commercial details can be scoped during onboarding.
Who benefits from priority fee ordering on Arbitrum One?
Searchers, market makers, pAMMs, DeFi protocols, and other teams whose results depend on transaction order. PGA is enabled by default, so teams only need to add standard EVM priority fees when earlier ordering is valuable.
How do chain operators enable PGA?
Upgrade the chain to the latest ArbOS release and activate tip collection. This gives users a familiar way to compete for priority while creating an additional source of chain revenue.
Read the docs to learn about enabling PGA on your chainHow does priority fee ordering work?
Higher priority fees compete for earlier ordering. Transactions with equal fees are ordered by arrival time, while transactions without a priority fee continue moving toward inclusion. Priority does not guarantee execution or profitability.
Read the docs for more information.
What does Fast Feed provide?
Fast Feed gives subscribers earlier access to transaction data after the sequencer determines its order. It provides earlier visibility but does not let subscribers change ordering or jump the queue.
How can Fast Feed improve the user experience?
Applications can use earlier visibility into ordered activity to refresh market views, risk indicators, transaction status, alerts, and other time-sensitive product experiences sooner.
How can teams combine Fast Feed with priority fees?
Fast Feed helps teams see ordered activity sooner. When that activity creates a time-sensitive opportunity, they can add a priority fee to express what earlier ordering is worth.
