Ethereum Attestation Service
@eas_eth
Open source infra for attesting. Structure and sign data about anything.
Excited to drop the ZK Playbook! 🔥 Building with zk + attestations is complicated. This playbook makes it easier so you ship faster and confidently. Special thanks to @ethereumfndn for supporting this research. Link below. PRs open.

🎽 Stepping in after @EthereumRemix to keep the @OctantApp Builder Relay alive. EAS is an open-source infra for making attestations about anything, onchain or offchain. We make it easy for builders to sign structured data that other people can rely on. Permissionless, tokenless,…
🎽 Keeping the @OctantApp Builder Relay going, thanks @buidlguidl for the handoff! Remix is a no-setup, web- and desktop-based IDE that powers smart contract development for everyone from beginners to protocol teams We have 700K monthly users and 33K daily contract deployments,…

We just wrapped our "Infra for Ethereum Data" livestream 💝 The TLDR • @eas_eth (Bryce): EAS has 8.2 M attestations proving everything from event attendance to contract ownership. They just launched a ZK proofs attestation guide, attesting with privacy. What's not to love? •…

Ethereum generates massive amounts of data every day But how do we store it? Verify it? Make it useful for builders? Without solid infra, nothing else matters... Tomorrow's livestream: the teams building the data layer that Ethereum runs on 💝 See you there ⤵️
