Scaffold JB Hackathon

Heads Up!

The repo link for JB Project Payer Extension – Tokens Receiver is incorrect. You can find the repo here, and a demo here.

Make an interesting project using scaffold-eth and Juicebox v2! Open to all teams and individuals.


  • Hackathon starts 12:00 EDT, July 1st.
  • Submissions close at 18:00 EDT, July 14th. Submit here.
  • Over $10,000 in rewards, distributed based on a JokeDAO token vote.
  • Collaboration between Juicebox DAO, Buidl Guidl, and JokeDAO.


Make an interesting project! Criteria is subjective and up to token recipients.

Our wish list:

  • A scaffold-eth starter kit for buidling a Juicebox project frontend.
  • A Juicebox protocol extension starter kit. See this repo.
  • A scaffold-eth NFT branch that sends funds to a Juicebox treasury. See
  • A Nouns clone: A sequential tokenID nft auction every x hours that pipes funds into a Juicebox treasury.
  • An all-in-one + Juicebox interface, with full read/write.
  • A buidl-guidl-centric dapp for managing the group's Juicebox treasury.
  • A fork which sends funds to a Juicebox treasury.

See what others are building in the Team Finder spreadsheet.


All projects must use scaffold-eth, Juicebox v2, and an open source license.

scaffold-eth provides an off-the-shelf stack for rapid prototyping on Ethereum, giving developers access to state-of-the-art tools to quickly learn and ship an Ethereum-based dApp.
