About

vlayer aims to unlock web3's potential with robust data infrastructure. We simplify zero-knowledge proofs, making privacy and verification tools accessible to smart contract developers on EVM compatible chains. By integrating web2 data (web and email proofs) into web3 apps, we support a decentralized, secure, and efficient internet.

We are on a mission to connect the otherwise disconnected worlds of Web2 and Web3.

We are building a new category - verifiable data infrastructure. Our all-in-one infrastructure layer allows developers to extract, verify and integrate real-world data into Ethereum smart contracts, in the form of trustless claims. By integrating web2 data (web and email proofs) into web3 apps, we support a decentralized, secure, and efficient internet.

Our technology is powered by state-of-art Zero Knowledge Proofs and optimised to provide the best developer experience.

Key features:

  • Time travel: leverage history of on-chain data in your contracts
  • Teleport: compute cross-chain data from EVMs
  • Email Proofs: tap into trusted contents of emails
  • Web Proofs: bring private Web2 data on-chain

Benefits of building with vlayer:

  • You can use Solidity and existing tooling like Foundry
  • No needs to learn new DSLs or programming languages
  • Access the key data sources directly from your Solidity smart contract

Prizes

🦸 Most inspiring use of vlayer superpowers$4,000

Create a dApp that uses verifiable data in on-chain contracts.

Examples:

  • Airdrop for successful DeFi traders,
  • Using LLM outputs by smart contracts or web3 games
  • Proof of contribution into DAO/Github to be eligible for airdrop
  • RWA use-cases like attesting ownership of certain items using email/web proofs
  • Consumer facing app that allows email usage for AA wallet recovery

Qualification Requirements

This application has it all - a great idea and best-in-class implementation. The application must use at least one of vlayer’s four superpowers, as well as incorporating both Prover and Verifier contracts.

🌐 Best use of Web Proofs$2,000

Show how private data coming from web2 services can be used on-chain.

Examples:

  • Proof of repost / reshare / mention on social media
  • Proof of balance in Revolut/PayPal
  • Proof of ARR/MRR in Stripe/Shopify
  • Proof of Reserves in Coinbase / Binance

Qualification Requirements

The application must use Web Proofs, as well as incorporating both Prover and Verifier contracts.

📧 Best use of Email Proofs$2,000

Show how emails can be used on-chain.

Examples:

  • Controlling AA wallet with email
  • NFT airdrop for people owning certain email domain

Qualification Requirements

The application must use Email Proofs, as well as incorporating both Prover and Verifier contracts.

🌀 Best use of Time Travel OR Teleport$2,000

Show how historic and cross-chain data can be used on-chain.

Examples:

  • Credit score for wallets using USDC or other ERC20
  • Rewards/Airdrops for owners of certain NFT/ERC20 tokens

Qualification Requirements

The application must use Time Travel OR Teleport, as well as incorporating both Prover and Verifier contracts.
