Frame It: Exploring the Arbitrum x Farcaster Buildathon

Introducing Frame It: A Buildathon for Arbitrum x Farcaster

We’re excited to announce that Arbitrum transaction support is now live on Farcaster!

To celebrate Arbitrum’s integration on Farcaster, we’re hosting Frame It: A Buildathon for developers to create Frames, with $500,000 in retroactive rewards. Starting now, you can build Frames with direct Arbitrum transaction support, giving Frame builders and users direct access to one of the biggest blockchain communities, Arbitrum.

Boasting a user base of over 350,000 accounts and over 59 million casts according to, Farcaster is leading the charge of bringing social onchain. Combined with well over 600 teams building on Arbitrum and an ever-growing community, we’re excited to see what builders will create as a result of this integration.


In total, we’ll be allocating $500,000 for Frame devs. $450,000 for Frame It and $50,000 reserved for IRL events such as Frameathons, meetups, workshops, etc. The first Farcaster x Arbitrum Frameathon will be held in NYC with $20,000 available in prizes for attendees who create Frames! Details to be announced soon.

As for Frame It, builders will have the opportunity to have their Frames embedded in casts by the main Arbitrum account on Warpcast.


For Frame builders, we encourage creativity. Consider what will drive usage for your Frame: build an NFT minter, a token deployer, integrate your existing DeFi app into a Frame, etc. The goal is innovation!

  • Frames must have an onchain component that lives on Arbitrum One (in-frame txs).
  • Frames that interact with Arbitrum Nova or other Arbitrum Orbit chains may also qualify.
  • Frame tooling/infrastructure that supports Arbitrum also qualifies.
  • Submissions must be by the original developer.
  • Frames must be deployed and live; bonus points for those that go viral.

Please allow up to 4 weeks for review of your Frame to determine eligibility for retroactive rewards. Reward amounts per Frame will vary based on its impact both onchain and socially, and how much of the initial budget remains.

Epoch 1 starts now and ends in 2 weeks on June 4th at 12pm EST. Each epoch lasts for 2 weeks, ending at 12pm EST on the last day of the epoch. The number of epochs may vary depending on the remaining budget.

You can submit your Frame for review here.


We can’t wait to see what you’ll create. Here are some helpful links:

  • Make sure you’re following us on Farcaster here.
  • To get started building with Frames, check out Farcaster’s docs.
  • If you’re new to Arbitrum, explore some example tutorials to get started.


How long will Frame It last?
Frame It will last roughly 9 epochs or 18 weeks, depending on weekly funding allocation, which is influenced by Frame submissions.

How are winners selected and prize pools divided?
The Arbitrum Foundation will hand-select Frames that meet the criteria. Higher rewards will be given for Frames that exceed expectations in usage or virality.
