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.

About Protocol
vlayer is a cryptographic protocol that turns private data from web, email, and on-chain sources into trusted proofs. With Zero Knowledge Proofs (ZKPs) and Multi-Party Computation (MPC), it enables secure verification without revealing sensitive information, giving developers a foundation for scalable, privacy-preserving applications.

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.
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.
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.
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
Seamless Onboarding
Replace document uploads with instant cryptographic proofs of address, income, or ID - faster, cheaper, and more private for businesses and users.
Trustworthy Finance
Enable KYC, AML, and credit scoring with zero exposure to raw personal data - making finance both compliant and privacy-preserving.
Verified Voting
Power elections, DAOs, or community polls with anonymous yet verifiable ballots, ensuring trust, fairness, and transparency in collective decisions.
Proof of Activity
Reward users based on verifiable past actions - balances, transactions, or achievements - for loyalty programs, airdrops, and more.
Influencer Authenticity
Verify social media reach and engagement with cryptographic proofs, cutting out bots and fake metrics to build real trust in digital influence.
Digital Governance
Support transparent civic systems and DAOs, where policies and programs run on verifiable, privacy-first proofs, enabling accountable participation.
