Kreedia

is a Web2.5 platform that empowers citizens to take direct action in cleaning their environment—and get rewarded for it in crypto. Through a gamified and verifiable cleanup process, users document polluted locations, participate in cleanups, and receive rewards in the form of onchain tokens and NFTs.

🌀 Project Flow:

• Users log in with their Google account and submit photos of polluted areas, including a selfie and geolocation.

• Verified NGOs review and approve submissions, then assign cleanup bounties in USDC, USDT, or DAI.

• Users can choose to clean the area themselves or leave it open for others.

• After the cleanup, the user submits a new “after” photo (again including themselves in the shot).

• Once validated, the worker is paid via a smart contract and receives NFTs representing their before/after contributions.

• These NFTs serve as proof of impact and are displayed on a public map.

⚙️ Tech Stack:

• Frontend: Next.js + Mapbox for geolocation and cleanup mapping

• Web3: Solidity, Hardhat, Scaffold-ETH 2, IPFS, RainbowKit, Wagmi

• ENS Integration: User & NGO identity + wallet simplicity

• EFP Integration: Onchain eco-reputation system

• NFT: Minted as ERC-721 and stored on IPFS
