Priority fees let users attach a tip to their transaction to influence transaction ordering. ArbOS Elara adds support for priority fee collection on Arbitrum chains. Importantly, this does not introduce front-running or sandwiching. Here's how it works. 👇

PGA + Fast Feed are now live on Arbitrum One. PGA enables priority fees for earlier execution, while Fast Feed gives subscribers faster access to ordered sequencer data. Here’s how they unlock new opportunities for traders & DeFi 👇

Arbitrum just got faster. Introducing Priority Gas Auctions (PGA) and Fast Feed, now live.

Having experienced firsthand what it means to build, stress-test, and scale underwritten infrastructure inside the @arbitrum ecosystem during Open House, we can’t recommend this enough for serious technical founders. ​When we participated, those intensive days of direct ecosystem mentorship and rapid iteration gave our agentic credit architecture the sharp focus it needed to move fast. ​If your team is building at the intersection of AI, autonomous agents, and financial primitives, do not sleep on this: ​• Direct Mentorship: Real-time feedback from core engineering leaders and top-tier partners. • High-Velocity Execution: Three focused days to ship features, validate risk models, and stress-test assumptions. • Ecosystem Alignment: Deep integration into the premier scaling home for institutional finance. ​Applications for the upcoming Arbitrum Open House are live. Build where the infrastructure actually scales.
