Opyn
Opyn is a decentralized options protocol on Arbitrum that raised $6.7M Series A funding led by Paradigm. Their main product Squeeth is a notable DeFi-native derivative. I implemented their initial trading interface and data indexing setup for Arbitrum Testnet using Next.js, Ponder, and viem/wagmi.
At Opyn, I built their trading interface with Next.js 14 and React Server Components. The frontend used shadcn/ui components based on Radix UI primitives with Tailwind CSS styling.
I implemented Ponder for blockchain data indexing, storing data in PostgreSQL via Supabase. Chain interactions were handled through viem/wagmi with Alchemy RPC endpoints.
The implementation prioritized type safety using Zod for schema validation, TanStack Query for data management, and nuqs for URL state handling.
Achievements
