Welcome EAS Builders!

This is an independent track for the Top 5 attestation-BASED builders that use attestations in a unique and impactful way during Onchain Summer.

☀️ Attention Onchain Summer Builders ☀️
This hackathon is independent of the Onchain Summer Buildathon hosted on Devfolio where you can choose tracks from only those listed on https://onchain-summer.devfolio.co/prizes. Using EAS does not qualify you for the Buildathon tracks, however, attestations may simplify your development and enhance your submission.

Why use Attestations this summer?

As an open-source primitive, Ethereum Attestation Service (EAS) can be used across all 8 Onchain Summer tracks in unique ways.

Attestations are digital signatures on structured data used to build trust online and onchain. You can use attestations in just about any project at varying degrees of integration, offchain or onchain. From simple attestations for community access to more complex systems entirely built on attestations. Read the docs to learn more.

We're excited to see how builders use attestations to build more trust online and onchain. If you use attestations during Onchain Summer, submit your project!
