Overview

RewardVault is an experimental smart contract that demonstrates transparent reward assignment and user-controlled reward claiming.

This project explores a minimal reward distribution architecture designed for simplicity, transparency, and on-chain verification.

---

Features

• Owner-managed reward assignment
• User self-claim mechanism
• Public reward visibility
• Lightweight architecture
• On-chain accounting

---

Smart Contract

Contract:

contracts/RewardVault.sol

Core functions:

• assignReward(address)
• claim()
• rewardOf(address)

---

Architecture

Owner ↓ Assign Reward ↓ Store Pending Reward ↓ User Claims Reward ↓ Reset Reward Balance
