When transaction ordering matters, take more control.
Arbitrum’s Priority Gas Auction lets you tip for priority, while waiting transactions gain a boost at no extra cost.
Watch the demo: competing tips, same-wallet ordering, and anti-starvation in action. 👇
Call for Arbitrum Developers 🇮🇳
ArbiVerse Mumbai Registrations are open.
You'll find about PGA and Fast Feed, what drives onchain revenue, zk, AI-driven development and builder programs, ecosystem support, as well as an @sgoldfed keynote on Arbitrum.
📆 When: 2nd November, right before Devcon @EFDevcon
📍Where: Mumbai, India 🇮🇳
Apply here 👇
What is Arbitrum Fast Feed?
It's a paid, authenticated WebSocket stream, that shows you ordered transactions before the block closes.
It is not a mempool view. It's not for publishing state. It's not for following the state of the chain with your Nitro node.
Who is Fast Feed for:
Those who run automated strategies that find and capture onchain opportunities.
Or want to react to ordered transactions sooner: arbitrage, liquidations, back-running. propAMMs and market makers: confirm price updates landed and reprice earlier in the round.
More about FF:
Building an onchain product starts with finding the right wedge.
Hear from our DevRel @blockbyvlog and @0xjesstech on how founders can find theirs at our upcoming Founder House Singapore in collaboration with Robinhood Chain.
Apply today. See you next week.👇

Fast Feed is the fastest official data stream from the Arbitrum Sequencer
Here's how to buy a ticket with USDG, connect, and maintain consistent access 👇
Great summary of what grants & opportunities are available for Arbitrum founders & devs 👇
One of the most common questions I get from developers and early founders: does @arbitrum have grants?
Yes. Here are 3 programs open right now that you can apply to today 🧵
If you're building in Perps, DEXs, Earn Products or Treasury operations on @arbitrum, this is for you:
Now that $USDG is a core stablecoin on Arbitrum One, here are some aspects I'd explore for your projects:
1. Embedded Earn: register wallets into payout groups, rewards accrue daily, claims run on a daily, weekly or monthly schedule. EIP-3009 signed batch transfers with time windows for cross-border payouts.
2. Perp DEX Margin: margin vaults earn through propose/accept registration. Balances don't change on their own; rewards are claimed separately.
3. Spot DEX Quote Asset: Pools can register and send rewards to LP incentives. Cross-chain via @LayerZero_Core OFT
4. Treasury Ops: Webhooks for: reconciliation, rules auto-mint USD → USDG and redeem USDG → USD to your bank 1:1.
Where would $USDG fit your roadmap?

Today in Switzerland:
@Arbitrum, @WisdomTreeFunds and an intimate community of institutional portfolio managers 🤝
A real privilege to meet with and be invited to host these private capital roundtables.
We covered a lot of ground from first principles across macro themes, capital flows and the role of crypto in model portfolios.
And then a deep dive and plenty of Q&A on the programmable economy.
This is the $30 trillion dollar opportunity that tokenization presents as public blockchains bring entire financial markets onchain.
Arbitrum is at the centre of bringing programmable economies together, with:
- a leading public chain (with more tokenized RWAs than any other) and
- a sought after blockchain tech stack (hosting enterprises like @RobinhoodApp).
Great way to kick off the first of our allocator-focused roundtables this week.
.@Arbitrum is oriented 100% towards growth.
Just wrapped Roundtable #1 with a room of private wealth advisors and asset managers here in Lugano.

What can a founder do on Arbitrum?
🔹 From apps on Arbitrum One to dedicated chains built around your own product.
🔸 Listen to @blockbyvlog from @arbitrum talk on how the Arbitrum stack works for builders 👇
Teams can now make their AI agents use smart wallets with guardrails built in with ZeroDev Kernel.
For example:
An agent can call one approved contract, spend only USDC, stay under $500 a day, and lose access Friday.
The owner key stays with the user.
See how it works. 👇

Variational is now the largest on-chain venue by volume for RWA derivatives (perps and swaps). We're just getting started.
What is PGA on Arbitrum?
Compete for transaction priority by attaching a priority fee to an individual transaction.
The sequencer calculates each transaction's final priority. Transactions with higher final priority are selected first.
What happens without a priority fee?
Setting a zero priority fee is fine when order doesn't matter. A zero-tip transaction generally follows higher-priority ones, but can still be included when capacity is available.
Who is PGA for?
> Atomic arbitrage: searchers race for the same price gap
> CEX-DEX arbitrage: the onchain leg must land before the DEX price moves
> Liquidations: several liquidators target one position
> propAMM updates: delayed quotes mean stale-state and inventory risk
> Apps where ordering affects execution quality, profitability, or protocol operation.
Builder Stories: Episode 1.
Hear from @TizianoTridico, Co-Founder of @DenariaFinance, on:
> bringing its perps platform out of stealth at Arbitrum’s Open House
> the opportunity for new founders joining the program
> taking home 3rd place at Arbitrum's Buildathon
And more.
