BlockNote is a lightweight smart contract designed for people who want to keep personal notes in a decentralized way. Every wallet address has its own set of private notes — meaning your data is stored only under your account and cannot be viewed or edited by others. This project demonstrates how decentralized storage can be used for privacy-oriented personal tools.

Future Asset Transfer is a simple Ethereum smart contract that enables automatic, time-locked transfers of Ether (ETH). It allows a sender to securely deposit funds that can only be withdrawn by a designated recipient after a specific future date/time. This project is perfect for beginners exploring Solidity, smart contract automation, and future asset management on the blockchain. Repository: https://github.com/ghoshrohit10/LegacyFi.git

ReportVault is a Solidity-based smart contract designed to securely store user-generated reports on the blockchain. Each report is permanently recorded with a title, content (or IPFS link), author address, and timestamp — making it transparent, immutable, and accessible to anyone. Built for learning, transparency, and decentralized record-keeping, ReportVault is ideal for beginner developers exploring Solidity and smart contract deployment.

WarrentChain.sol is a Solidity smart contract that records and manages product warranties on a public or permissioned blockchain. Each warranty entry is stored immutably with a unique identifier, timestamps, product metadata (serial/model), warranty terms, issuer identity, and owner address. The contract exposes functions for issuing, transferring, and verifying warranties, emits events for off-chain indexers, and includes access control to restrict issuance and claim processing to authorized…

PattharGame is an educational and entertaining blockchain project that brings the classic “Rock Paper Scissors” game to the Ethereum network. It is written in Solidity, designed for fair, transparent, and trustless gameplay, where all actions and results are recorded on-chain.

A beginner-friendly Ethereum smart contract that enables transparent donation collection and distribution — every donation and withdrawal is recorded on-chain for full visibility.

A beginner-friendly smart contract written in Solidity that demonstrates how a voting system can be built on the Ethereum blockchain. It allows the contract owner to add candidates, start and end elections, and voters to securely cast their votes — all in a transparent, decentralized manner.https://github.com/nehha414/votex

🧩 Project Description The SpinGame smart contract is a beginner-friendly decentralized game that demonstrates how to use Solidity to create a luck-based game with pseudo-random outcomes. It allows users to: Spin for rewards. Claim their winnings. Watch transactions and rewards on-chain for full transparency. This project is perfect for developers who are learning Solidity, randomness handling, and basic smart contract design patterns. my github link: https://github.com/Anusua-2005/game_spin

BlOClatCh is a simple, educational Solidity smart contract designed to explore one of the most fundamental challenges in blockchain development: generating verifiable randomness for games. It simulates a basic "flip and match" game where players try to match two hidden "cards" (numbers) drawn by the contract. While it's a fun, lightweight concept, it serves as a critical demonstration of why relying on simple on-chain data for randomness is risky! https://github.com/sohagbanik/BlOClatCh

This project is a decentralized checklist and progress-tracking system built using a Solidity smart contract. It allows users to create, manage, and complete their personal tasks directly on the blockchain, without relying on any centralized application or database. Each user, identified by their wallet address, receives their own secure on-chain task list where they can add new tasks, mark tasks as completed, and monitor their overall progress through an automatically calculated completion…
