Simple Lottery Vault is a decentralized lottery contract built on the Flow Testnet. It allows users to join by sending a small, fixed amount of cryptocurrency and randomly selects one winner who recei
Creating cross-platform NFTs with interoperable attributes
The Scavenger Hunt NFT Game allows players to participate in a clue-based adventure managed by an admin. Players who successfully complete all the challenges are marked as winners.
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
A minimal Solidity voting contract on Flow EVM Testnet rewarding voters with VOTE tokens. Users can vote, add proposals, or burn tokens to vote again. Address: 0x28F70623eDd7641549eF7537ecDFEFac23727D
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
This DApp is a simple, decentralized Number Guessing Game smart contract deployed on the Flow EVM. Players can guess a secret number on-chain for a chance to win an ETH prize.
