Why join the L2 Rollathon?

While buzzwords are tantamount to a dynamic crypto environment, some of them have cause to stick. Although Layer 2 scaling ecosystems are still quite young, 2022 is shaping to be an L222 year for Ethereumโ€™s ecosystem as these various networks take off and gain traction. As teams continue to work on gas optimizations, user experiences, dev tools, and network constraints, they will start to bring a lot of developer attention which will bolster the Ethereum ecosystem as a whole.

Consensys, 2022

Gitcoin Events aims to ready developers for such a future by collaborating with top organizations working in the L2 ecosystem. In hosting the L2 Rollathon, we're on a mission to engage, onboard, and educate participants on scaling protocols and tooling to create the best possible UX for the future of web3.


Join Gitcoinโ€™s vibrant community of developers getting paid to build open source. This community includes more than 200,000 active builders who have collectively generated $50+ million for digital public goods. Join a sponsored hackathon and team up with fellow hackers to tackle new challenges, learn new skills, and earn rewards in the process!
