APERO

APERO is a decentralized Research & Development network specifically designed to accelerate aerospace engineering, next-generation propulsion, and advanced materials science. Traditional aerospace R&D is often stifled by immense capital requirements, opaque funding mechanisms, and siloed intellectual property. APERO solves these bottlenecks by leveraging Ethereum to create a transparent, community-driven ecosystem where innovators can fund, build, and protect their breakthrough technologies.

At its core, APERO consists of four distinct but interconnected modules:

PiggyBank DApp: A fully functional decentralized savings account deployed on the Ethereum Sepolia Testnet. It serves as an accessible entry point to Web3, allowing any user to seamlessly deposit ETH to support the ecosystem, while restricted access controls ensure that only authorized owners can withdraw funds.

Launchpad: A transparent, decentralized crowdfunding platform where university labs, independent engineers, and startups can pitch their research proposals (e.g., wind tunnel testing for scramjet nozzles, or synthesizing new ceramic matrix composites). Funds are committed by the community and locked in smart contracts, only being released linearly or upon the successful completion of verified milestones, ensuring accountability.

IP Vault: A secure registry that transforms complex R&D outputs—such as CAD models, computational fluid dynamics (CFD) reports, and structural blueprints—into Intellectual Property NFTs (IP-NFTs). This ensures immutable proof of ownership for researchers and enables programmatic, frictionless royalty distributions whenever their designs are licensed or utilized by the commercial industry.

DAO Governance: A community treasury managed by token holders (engineers, researchers, and early backers) who vote on active proposals. The DAO directly influences which high-impact aerospace projects receive grant funding, decentralizing the decision-making process traditionally held by institutional gatekeepers.

By combining an intuitive, premium glassmorphism interface with robust smart contracts on Sepolia, APERO bridges the gap between physical engineering and decentralized networks, aiming to fund the technologies that will take humanity further into the cosmos.

APERO is built with a modern Web3 stack, combining a React 19 frontend (bootstrapped with Vite 8) with a Solidity smart contract deployed on Ethereum Sepolia testnet. The frontend uses Ethers.js v6 for all blockchain interactions — wallet connection, contract reads, and transaction signing — all through MetaMask's injected provider.

The core DApp is the PiggyBank smart contract, written in Solidity ^0.8.19. It's a straightforward yet effective savings contract where anyone can deposit ETH, but only the contract owner can withdraw. We deliberately kept the contract minimal and gas-efficient, using native receive() for deposits and a single withdraw() function with owner-only access control. The contract was compiled and deployed via Remix IDE using Injected Provider.

On the frontend, we used vanilla CSS with a custom design system built around CSS custom properties — no Tailwind or UI libraries. This gave us full control over the dark-theme glassmorphism aesthetic with gradient accents, floating particle animations, and scroll-reveal effects powered by the IntersectionObserver API. The entire UI is responsive with a custom hamburger menu for mobile.

The app is structured with React Router for client-side navigation across five pages: a landing page with stats and feature cards, the PiggyBank DApp interface, a Launchpad for R&D crowdfunding with category filters, an IP Vault showcasing IP-NFT concepts, and a DAO governance page with proposal voting. State management is kept simple with React hooks — no Redux or external state libraries needed.

One notable hack: we used Vite's import.meta.env to make the contract address configurable via environment variables, so switching between testnet deployments is seamless without code changes.
