Protocol vs. Application

One protocol. Many applications.

Protocol

vlayer gives developers tools to extract, verify, and integrate real-world data into Ethereum smart contracts. It creates verifiable proofs from multiple sources, powering apps like Vouch and enabling an open ecosystem built on trusted data.

For Developers

Learn How it Works

Application

Built on vlayer, Vouch lets businesses verify user-owned data from online platforms without touching sensitive information. Attestations are created on users’ devices, ensuring privacy and secure verification.

About Protocol

vlayer is a cryptographic protocol that turns private data from web, email, and on-chain sources into trusted proofs.

By combining Zero-Knowledge Proofs (ZKPs) and Multi-Party Computation (MPC), it enables secure verification without revealing sensitive information, thereby giving developers a scalable foundation for privacy-preserving applications.

Proofs generated

Web Proofs

Bring verified web data – from APIs to dynamic content – directly into smart contracts. Secure, trustless integration of off-chain information with on-chain logic.

Documentation

Examples

Email Proofs

Turn email content into on-chain inputs. Enable powerful workflows like wallet recovery, account linking, identity checks, and more – all verifiable through cryptographic proofs.

Documentation

Examples

Time Travel

Access and verify historical on-chain data, such as ETH balances or token holdings. Power use cases like airdrops, governance voting, audits, and eligibility checks with reliable past-state proofs.

Documentation

Examples

Teleport

Prove and act on data across EVM-compatible chains. Enable cross-chain logic for lending, collateralization, gated access, and other multi-chain applications.

For Developers

Integrate cryptographic proofs directly into  your apps and smart contracts to enable  secure, privacy-preserving logic.

For Businesses

Build products that verify user-owned data without handling sensitive information, reducing compliance risk and cost.

For Innovators

Explore new use cases powered by secure attestations, from identity to finance to  cross-chain interactions.

Use Cases

Proof of Reserves

Automate transparent reserve attestations with live cryptographic proofs from banks and custodians, ensuring compliance, trust, and real-time visibility without revealing sensitive balances.

Proof of Activity

Reward users, creators, or partners based on verifiable actions such as campaigns, loyalty programs, or in-game achievements, using privacy-preserving proofs of transactions and engagement.

Proof of Address

Verify a user’s residency directly from trusted financial or utility accounts, eliminating document uploads while maintaining compliance and privacy.

Proof of Identity

Enable seamless user verification with minimal data exposure. Use zero-knowledge proofs from verified accounts to confirm identity or account ownership without relying on third-party KYC vendors.

Proof of Employment

Verify an individual’s current or past employment directly from payroll, government, or enterprise systems, enabling secure income verification, lending, and onboarding flows that protect privacy at every step.
