## Description

Explore the next generation of Solidity development with Artur Chmaro as he introduces vlayer’s ZK superpowers at ETHGlobal Prague 2025. Learn how vlayer empowers Web3 developers with four groundbreaking features: Web Proofs, Email Proofs, Time Travel, and Teleport—tools that bridge off-chain Web2 data and on-chain verifiability using zero-knowledge proofs.

Artur explains vlayer’s new prover-verifier execution model, how to build private, off-chain computations in Solidity, and how to verify them on any EVM-compatible chain. Discover how to integrate HTTP responses, email content, historical blockchain state, and cross-chain data directly into your dApps—without compromising security or UX.

This talk also includes information on vlayer hackathon bounties, developer templates, and how to get started with your first zk-enabled dApp using vlayer’s powerful SDK.
