- Full-stack development: dApp front end and multi-chain contract indexing

Overview
proof2work is an open tool that lets anyone search all smart contracts deployed by a given address across Ethereum, Polygon, Arbitrum, and Optimism.
The challenge
Give builders and reviewers a fast way to verify what an address has actually shipped on-chain across multiple EVM networks.
What we built
We built a dApp that queries contract deployments across Ethereum, Polygon, Arbitrum, and Optimism and presents them in one searchable interface.
