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 Ethereum’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 Gitcoin’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!
