Unlock data from all sources and transform them into actionable on-chain claims.

Web2

Harness petabytes of private data from centralized platforms.

Email

Leverage contents of one's email box within your web3 workflow.

On-chain

Tap into raw and processed blockchain history across L1s and L2s.

[ Paradigm Shift ]Imagine a decentralized world where 'trustless' is the norm and the utility of dApps stands unrivaled.

Decentralized finance 2.0

Imagine DeFi and RWA volumes explode thanks to the trustless and privacy-preserving way of processing data required for effective underwriting.

Smart user acquisition

Imagine a permissionless segmentation of prospects based on what they own and do on-chain, enabling you to target only those who are likely to respond.

Dawn of permissionless
marketplaces

Imagine web2 data finally owned by the users, enabling new business models where centralized marketplaces meet permissionless decentralization.

Unlimited possibilities

Imagine a world that you can finally co-build thanks to boundless data with vlayer. Stay tuned for what's coming.

This world is being built. But there are challenges.

This world is being built. But there are challenges.

Limitations of on-chain data processing

Building a decision logic based on Ethereum's full history is challenging.

Lack of cross-chain interoperability of data

On-chain storage and event data are isolated within their blockchains, making a holistic user view impossible.

Non-exhaustive approach to data sources

Some developers build on top of a single, verifiable data source, reducing applicability and increasing trust assumptions.

No one is adressing these utility blockers holistically.

No one holistically addresses the utility blockers.

No one, but vlayer.

Shadow copy 

of Ethereum

With vlayer, you can compute over unlimited history of Ethereum and L2s or import one of the pre-built indexers.

The ultimate layer

vlayer checks the verifiable data wishlist of any web3 developer, bringing a familiar and powerful toolkit for all applications: on-chain, off-chain and hybrid.

Developer experience matters

Math abstracted away – you don't need to understand complex mathematics underlying zero knowledge proofs to build powerful dApps anymore.

High-level coding
You don't need to code error prone circuits in an unfamiliar language to bring in private data to your contracts.

Audited plug-and-play
vlayer brings "out-of-the-box", formally verified, pre-audited granular building blocks that you can import straight to your Solidity contract.

Infrastructure you can trust

Infrastructure built on top of state-of-the-art zero-knowledge proofs guarantees verifiability. You don't need to trust us or any other institution, as long as you trust formally verified and audited code.

Self-verifying technology

Zero-knowledge proofs ensure every transaction is independently verifiable.

Independently secure
Formally verified and audited code eliminates the need for institutional trust.

User privacy is important

With vlayer, user data is converted into anonymous composable claims and only then handled publicly on-chain.

Anonymous claims

User data is transformed into anonymous claims before being processed on-chain.

Developer control
As a developer, you control the claim template, data used for proof generation, and what is published on-chain.

No one holistically addresses the utility blockers.

No one, but vlayer.

Queryable Ethereum

With vlayer, you can compute over unlimited history of Ethereum and L2s or import one of the pre-built indexers.

Native on- and off-chain interoperability

With vlayer, you enjoy the swift way of building smart contracts: based on claims from web2 and various web3 L1s/L2s.

Infrastructure built on top of state-of-the-art zero-knowledge proofs guartantees verifiability

You don't need to trust us or any other institution.
You simply trust the code.

User privacy is important

With vlayer user data is converted into anonymous composable claims and only then handled publicly on-chain.

As a developer you are in full control of which claim template is used and exactly what data will be used for proof generation as well as what will be later published on-chain.

Let's make the decentralized future reality – together

Supercharge your web3 solution with verifiable data from many, many sources – like web2 apps, emails, or the blockchain itself – and unlock its unlimited potential.
