🧱Tech Stack

Fume’s technology stack blends blockchain infrastructure with modern web technologies to deliver a secure, efficient, and user-friendly on-chain fund administration platform.

The tech stack used for the different aspects of the app

🧩 Blockchain Layer

• Solidity – Used to write smart contracts managing fund operations such as subscriptions, redemptions, and fee distributions.

• Ethereum / Arbitrum / Base – Main EVM-compatible blockchains where Fume’s smart contracts are deployed. More blockchains are possible depending on client demand.

• Alchemy – RPC Node provider ensuring reliable blockchain connectivity and transaction handling.

• Wagmi & Viem – Client libraries used for wallet connections and blockchain interactions in the frontend.

• Safe (Gnosis Safe) – Enables multi-signature wallets for fund and investor custody, ensuring secure asset management.

• ChainSecurity – External partner used for smart contract audits to guarantee code safety.

• GitHub Copilot & Cursor – AI-assisted coding for smart contract and backend development efficiency.

🖥 Server Layer

• Vercel – Hosts the web app and backend API with fast, serverless deployment.

• Neon – PostgreSQL databases, integrated into Vercel.

• Prisma – ORM (Object Relational Mapper) connecting the backend to databases for user and fund metadata management.

• Sentry – Monitors errors and performance in real-time across backend and frontend.

• Privy – Login solution, abstracts complexity and consolidates user objects. Allows for embedded wallets and server wallets.

• Stripe – Payment processor.

• Resend – Mailer system for all product communications and transactional emails.

💻 App Layer (Frontend)

• React & Next.js – Frameworks for building a fast, modular web application.

• Typescript – Used.

• TailwindCSS – Used for clean and responsive UI design.

• Jest – Testing framework to ensure the reliability of the app’s components and logic.

• Privy – Login system, allows users to login with web2 or web3 means and provides embedded wallets for web2-based logins

👛 User Side

• Users interact with the platform through providers such as Safe, WalletConnect, providing secure, non-custodial access to funds.

• The wallet connects directly to the on-chain fund contracts via the frontend, ensuring transactions remain decentralized and verifiable.

Summary

Fume’s stack combines:

• Blockchain reliability (Ethereum, Safe, Alchemy),

• Modern web performance (Next.js, Vercel),

• Developer safety (ChainSecurity, Sentry, Jest), to deliver a compliant, auditable, and scalable infrastructure for on-chain fund administration.
