maticnetwork/pos-portal
★ 427 · ⑂ 282

The bridge contracts that move assets between Ethereum and Polygon PoS — one of the most heavily used bridges in the ecosystem.

full-stack dApp

A blockchain event-ticketing platform I built end to end across five repos — the ticket smart contracts, a REST API, an admin cockpit, a customer store, and a React Native app for scanning tickets on-chain.
