Inspiration

Covet was inspired by the demand for a more equitable NFT market. Currently, exorbitant floor prices inhibit newcomer participation.

Our mission was to provide a fair and transparent method for acquiring NFTs through a VRF-powered raffle, thereby lowering the barrier to entry. By offering affordable tickets and a chance to win highly coveted NFTs, Covet seeks to democratize and enhance inclusivity in the NFT market.

What it does

Covet allows NFT owners to initiate raffles with slot, ticket price, and start/end date customization. SupraOracles Verifiable Random Functions (VRFs) are utilized for trustless, pseudorandom winner selection. Prior to winner selection, users can purchase/refund tickets prior to winner selection and NFT owners can delete raffles.

The app also features an automated NFT and owner funds disbursement, including a 3% commission for Covet platform owners (via an ownable vault contract).

How we built it

The front-end was built using HTML, CSS (Tailwind), and JavaScript (React), with wallet integration functionality provided by thirdweb's SDK. The website and app pages feature a modern aesthetic, entailing rounded corners and bright, complementary colors, creating a stunning UI. The result is a highly engaging and user-friendly interface that allows users to easily navigate the platform, participate in raffles, and manage their NFTs.

The back-end was built in Solidity, leveraging Hardhat, OpenZeppelin (SafeMath.sol, ERC-72.sol, and Ownable.sol). The SupraOracle VRFs play a crucial role in the system, providing automated callback functions that streamline the asset disbursement process for participants.
