zkVerify x zkEmail: Bringing Privacy-Preserving Email Proofs to Web3

We’re excited to announce our integration with zkEmail, a novel protocol that brings zero-knowledge proofs to the world’s most ubiquitous communication layer—email.

What is zkEmail?

With zkEmail, users can generate cryptographic proofs tied to email content, sender domains, or metadata without revealing the actual contents. It’s a breakthrough for applications requiring secure, selective disclosure, like decentralized KYC, off-chain payment attestations, and proof of event participation.

What Does zkVerify Bring to zkEmail?

Now, developers can verify zkEmail Groth16 proofs using zkVerify’s high-performance infrastructure at 10 times cheaper than traditional L1 verification. This unlocks real-world applications where trust and privacy converge, from wallet recovery and verifiable credentials to compliance workflows and beyond.

Built for universal compatibility, zkVerify ensures Groth16 proof verification is faster, cheaper, and easier to deploy across Web2 and Web3 environments.

The zkVerify and zkEmail integration is a step toward a truly interoperable Web3, where digital trust and user privacy go hand in hand:

• Privacy-first UX: Verify ownership or contents of an email without exposing them on-chain.
• Cross-system interoperability: Connect traditional email systems to blockchain apps with trustless verification.
• Cost efficiency at scale: Slash proof verification costs by over 90%, enabling mass adoption.
