A decentralized sealed-bid auction smart contract using Solidity. The auction consists of a bidding and revealing phase to ensure fairness and privacy. The contract includes safe bidding logic, error handling, and secure fund transfer. Created as part of my deeper dive into Ethereum smart contract patterns.

Blind Auction DApp

A basic decentralized application (DApp) built using Solidity, React, and Tailwind CSS. It features a clean UI where users can input two numbers and perform basic arithmetic operations—addition, subtraction, multiplication, and division—on the Ethereum blockchain. MetaMask is used for wallet connection, and the smart contract is deployed on Remix IDE. This was my first end-to-end blockchain project, integrating smart contracts with a React frontend.

Calculator DApp

A frontend interface built using React and Web3.js to interact with ERC-20 tokens. Users can check balances, transfer tokens, and view token metadata. Smart contracts deployed on the Ethereum testnet. The project provides a simple but complete user experience for understanding fungible tokens.

Fungible Token Interface (ERC-20)

A decentralized bug bounty platform enabling secure collaboration between developers and auditors. Users can create or solve bounties tied to GitHub issues. The smart contract ensures funds are held in escrow and released upon merge verification. Designed in a DEX-like environment with authentication reuse, the platform supports seamless wallet interaction, GitHub repo linking, and reward distribution. Flow: Bounty creators deposit tokens with issue details. Solvers claim bounty after GitHub PR verification and identity check. On successful validation, funds are automatically transferred.

Hive Bounty Platform

Tailwind Frontends

A cross-chain bridge smart contract enabling secure and verifiable asset transfers and messaging between blockchain networks. Vedu Bridge focuses on lightweight, modular bridging logic suitable for testnet experimentation and future scalability. The contract handles token locking on the source chain and proof-based unlocking on the destination chain. Core Features: Lock–mint–burn–release mechanism Origin chain verification Event-based off-chain relayer trigger
