Recap: Arbitrum at ETHcc
Finally back home after weeks of traveling - feeling full of energy, memories, and with a lot of new friends and valuable connections. ETHcc was a big success for Arbitrum. With the Robinhood partnership announcement, we were the talk of the town. Arbitrum Everywhere. 
Here’s a quick recap of what went down:
1. Arbitrum DAO Delegates Dinner - Monday, 30 June
On June 30, 2025, we hosted an Arbitrum DAO Delegates Dinner at Bella Storia, a cozy Italian restaurant. A total of 18 delegates and 2 Arbitrum Foundation representatives joined. It was a relaxed evening with no agenda - no talks, no workshops. Just good food and great company. For many of us, it was the first time meeting in person, which made it even more special.
2. Arbitrum DAO Morning Run - Tuesday, 1 July
This was the most popular fitness side event at ETHcc, and once again, we were the talk of the town. Over 1,000 people signed up to run through the city in the early morning heat. In the end, around 80–100 people showed up. The largest running side event I’ve ever seen. The group was so big, we had to stop traffic just to cross the road. 
At the end of the run, we handed out a POAP on Arbitrum. A total of 37 collectors claimed it via geo-location mint or their NFC card.

3. Arbi Brunch with Robinhood - Wednesday 2 July
Wednesday morning’s Arbi Brunch was hosted at La Bombola café. Most of the Arbitrum team came by, along with many delegates, AF members, OCL team members, and builders from the ecosystem. The event was casual, with good food and even better networking. We also handed out some cool merch. The energy was high, and the Robinhood partnership was the main topic of conversation.
4. Arbitrum Delegates Day - Thursday 3 July
Thursday was Arbitrum Delegates Day, an invite-only event for larger delegates and members from AAEs. It is not known to me what was discussed, but I expect we’ll hear more during upcoming community calls or on the forums.
