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. 👇

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:
Arbitrum's new Fast Feed streams transactions straight from the Sequencer, before the public feed. It's a permissionless onchain subscription paid in USDG, with dynamic per-round pricing. Built for searchers, market makers, and propAMMs that need the fastest data.

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? arbitrum.io/products/usdg-va…

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.

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. 👇

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.
