ETH <> NEAR Bridge Hackathon

Hello hackers and builders! Today we are super excited to soft launch Hack the Rainbow in collaboration with Gitcoin! Hack the Rainbow is NEAR’s first MOOH! (Massive Open Online Hackathon) and is primarily focused on building bridges between NEAR and the Ethereum ecosystems. 

There’s plenty of opportunities for everyone to participate and help grow the Open Web by building bridges. Read on to discover how you can get involved!

  • Teams and individuals can sign-up on Gitcoin starting today! 
  • $50K+ main prize pool (in NEAR & DAI) and additional bounties from Hackathon partners 
  • 20% referral bonus for NEAR Guilds and hacker clubs/dev groups who refer participants

🌈 Why Hack the Rainbow?

Hack the Rainbow 🌈 will be a creative, collaborative, cross chain hackathon focused on building the bridges needed to make web3 an accessible reality for everyone. Our aim is to work with our Ethereum partners and bring together the best tools for that build.

This is our collective chance to explore and create that "wide range of related and colourful things" that can bring Ethereum and NEAR together. We see it as a chance to deliver community education and broaden opportunity for everyone wanting to explore the power of interoperability and interconnectedness.

πŸŒ‰ The Rainbow Bridge

The Rainbow Bridge allows developers to utilize Ethereum assets and smart contracts on NEARβ€”a fast, scalable, and low-cost environment. The Bridge has the power to accelerate community development as it allows ETH users immediate access to apps built on NEAR.

This is the first trustless bridge of its kind. It supports ERC20, ERC721, and remains fully decentralized and adaptable to any future protocol changes on either side. You can already check out the Github repo and read the launch blog to find out more about the bridge. 

🀩 What to expect:

Our two week hackathon starts September 15 but will be preceded by two weeks of educational content so that all participants can get up to speed with NEAR, the bridge and all the possibilities. All workshops will be recorded on Crowdcast and available publicly for you to watch at any time! You can watch some of the previous workshops here on Crowdcast and make sure to follow us to get the latest updates.
