InteractionLogger is a minimalistic Solidity smart contract that logs every on-chain interaction with its timestamp and caller address.
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
DynamicVolumePricedToken (symbol: DVP) is an experimental ERC20-style token with a dynamic pricing mechanism that automatically adjusts the token price based on cumulative trading volume.
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. The contract features au
A decentralized Collaborative Research Funding Pool built on Solidity. This smart contract allows contributors to pool ETH, create proposals for research funding, vote on them, and automatically relea
The Sentiment-Influenced Voting System is an innovative blockchain-based project that redefines traditional voting by introducing emotion-driven decision dynamics. Built on the Flow Blockchain, this s
This project demonstrates how verified users can mint NFTs using a Zero-Knowledge Proof mechanism — without needing to import external libraries or define input parameters.
Voting System Smart Contract
This Solidity contract is a lightweight, self-contained implementation of an **ERC-721-like NFT standard** designed for AI-generated art with evolving metadata. Unlike typical NFT contracts, it avoids
🧠 Dynamic AI Art NFT This Solidity smart contract creates AI-generated NFTs with dynamic metadata, allowing on-chain updates of token URIs for evolving or adaptive artworks. It’s a lightweight, cons
A simple, on-chain ETH vault that locks funds until a specified time.
Implement a token with dynamic pricing based on volume, write this smart contract in Solidity, no imports and constructors, with no input fields
