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

๐Ÿฆธ Most inspiring use of vlayer superpowers โธบ $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 vlayerโ€™s four superpowers, as well as incorporating both Prover and Verifier contracts.

๐ŸŒ Best use of Web Proofs โธบ $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.

๐Ÿ“ง Best use of Email Proofs โธบ $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.

๐ŸŒ€ Best use of Time Travel OR Teleport โธบ $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.
