StarkFlux is the first encrypted component marketplace on StarkNet.
Developers can upload reusable Cairo modules, SDK helpers or tooling scripts, set a price in USD, and get paid instantly in STRK—while buyers enjoy one-click, licence-safe installs.

Step | On-chain / Off-chain action |
|---|---|
1. Encrypted upload | 100 % browser-side ZIP → AES-CTR encryption → pinned to IPFS. Only a 31-char CID is stored on-chain. |
2. USD-pegged pricing | Seller enters a USD amount; Pragma Oracle converts to live STRK at purchase (< 1 h staleness). |
3. Revenue split | Every sale auto-routes 80 % to the dev, 10 % to the platform treasury, 10 % to the Liquidity Vault. |
4. Decrypt & import | After payment, Lit Protocol releases the AES key; the buyer’s browser decrypts and unpacks the component. |
Predictable economics – Oracle-backed pricing shields both sides from token volatility.
No middlemen – royalties flow directly to devs on-chain.
Trust once, reuse forever – components carry audit hashes; downstream teams skip redundant audits.
Bootstrapped liquidity – the vault aggregates fees to seed DEX LP and, later, staking rewards.
Cairo 1.2 smart-contract suite
ComponentRegistry v1.2.1 – marketplace logic
IdentityRegistry v1.2.0 – dev reputation & metrics
React 18 · TypeScript · Vite front-end
starknet.js for contract calls, @starknet-react/core hooks
Pinata IPFS + Web Crypto for encrypted storage
Pragma Oracle for STRK / USD feed
Contracts are live on StarkNet Sepolia; class-hashes and ABIs are in the public repo. Subscriptions (Dev & Market) and a Liquidity-Vault dashboard are under active development.
Over 15 days of focused solo work, I designed and deployed the foundation of StarkFlux, a decentralized marketplace for developer components on StarkNet. During the hackathon, I: - Implemented and deployed two core smart contracts: - ComponentRegistry (v1.2.1) — supports component uploads, pricing, and oracle-based conversion. - IdentityRegistry (v1.2.0) — manages developer metrics and reputation. - Built additional smart contracts for component purchasing, developer subscriptions, and marketplace subscriptions (pending integration). - Integrated the Pragma Oracle to fetch STRK ↔ USD prices with <1hr staleness. - Developed fully browser-side encrypted uploads to IPFS (≤200MB), using Web Crypto and no backend. - Built the frontend app with React 18, Starknet.js, TypeScript, and Vite. - Released developer registration and component listing functionality. - Published the full contract source and documentation on GitHub.
