Welcome to the database where you can see all previous projects from our past hackathons.
A simple Solidity smart contract that logs every user interaction on the blockchain, storing the caller’s address, the current timestamp, and the block number.
A blockchain-based Time Capsule smart contract that securely locks messages or tokens until a specified future date, ensuring tamper-proof and time-locked access on the Ethereum network.
This project contains a fully on-chain NFT smart contract written in pure Solidity-style syntax (conceptual reference) — designed for AI-generated art with dynamic metadata, adapted for deployment on
Creating cross-platform NFTs with interoperable attributes
This contract serves as a decentralized personal savings vault for ETH. Each wallet address maintains its own internal balance. Funds can be deposited and withdrawn at any time — all directly on-c
A simple NFT smart contract built on the Flow blockchain that mints completion badges for courses or tasks. Users can earn unique, transferable badges as proof of achievement—without the complexity of
ZKP Verified NFT is a decentralized smart contract that issues NFTs to users who are cryptographically verified using Zero-Knowledge Proofs (ZKPs). The system ensures privacy-preserving identity valid
**without providing any input fields**. Each log entry automatically captures the caller’s address and the exact timestamp when the interaction occurred. This contract is **deployed on the FLOW
xyz
EngageToken is a smart contract deployed on the Flow EVM Testnet that rewards users with tokens based on their social media engagement. Trusted verifiers calculate engagement metrics (likes, comments,
A fully on-chain AI-generated NFT collection where each artwork is procedurally generated using on-chain randomness.
A simple ERC20 token with a built-in faucet that lets each wallet claim 1000 FTK once. No imports, no constructor, and fully autonomous on-chain.
