About
Smallcase DeFi is a full-stack monorepo that lets investors discover and subscribe to curated on-chain strategies while maintaining compliant access through zero-knowledge identity checks. The web app (Next.js) renders a catalog of strategies and can overlay live on-chain metrics (NAV, PPS, PnL) sourced from a Uniswap v4 vault contract. Identity verification is handled by the Safe Passport package, which integrates Self Protocol V2 to prove attributes like age and OFAC status for investors and jurisdiction/RIA for portfolio managers (PMs).
How it's made
We used the following technologies to build this project: * Web App: Next.js 14 App Router, Tailwind CSS, Radix UI components, and Clerk middleware for route protection (`apps/web/`). * Identity: `packages/safe-passport/` provides a Solidity contract (`SafePassport.sol`) and a TypeScript SDK to generate Self Protocol QR flows. Investor (age + OFAC) verification. See `apps/web/components/self/SafePassportWidget.tsx` and `apps/web/app/investor/kyc/self-verify/page.tsx`. * On-chain Strategies: `packages/uniswap_integration/` contains a Uniswap v4 hook (`MultiPolicyHook.sol`), a strategy vault (`UniswapLPVault.sol`), and a registry (`UniswapStrategyRegistry.sol`), plus scripts to deploy/configure and emit snapshots for charts. * Database: `packages/database/` exposes a Postgres/Prisma package with a schema for strategies, users/subscriptions, and analytics; intended for optional persistence and ingestion. * On-chain reads: server-side `viem` client in the web app to overlay live metrics onto the existing strategy list via an API route. We used the following partner technologies to benefit our project: * Self Protocol V2 (via `@selfxyz/*`) for ZK identity verification flows and QR code builder. * Neon Postgres + Prisma for managed serverless database access (optional for the demo). * Clerk/Privy for auth primitives and middleware. We did the following frugal integration in our project: * Bootstrapped a curated strategy list from static data (`apps/web/data/strategies.ts`) and overlaid live Uniswap metrics via an API, so the UI stays fast even when metrics are unavailable. * Emitted demo snapshots from scripts to drive charts quickly during testing. * Graceful fallbacks: UI renders fine without on-chain metrics or DB connection.
