A simple Solidity smart contract that enables manufacturers to register product warranties on the blockchain and allows users to verify or transfer those warranties easily and transparently.
The Smart Warranty Registration & Validation System is a blockchain-based solution for securely recording and verifying product warranties.
It replaces traditional paper or centralized warranty systems with a decentralized ledger that ensures transparency, security, and trust between manufacturers and buyers.
Build a simple Solidity smart contract that records product warranties on the blockchain. Manufacturers should be able to register new warranties, while users can verify ownership, check authenticity, and transfer warranties to others. The goal is to make warranty management transparent, secure, and effortless for both manufacturers and consumers.
The problem is that traditional warranty systems are hard to verify, easy to lose or forge, and often difficult to transfer when a product is resold. Records depend on a centralized authority, so users can’t independently confirm authenticity or ownership. A blockchain-based smart contract solves this by creating a tamper-proof, transparent, and easily transferable record of product warranties.
✅ Warranty Registration — Only the manufacturer (contract deployer) can register new warranties.
✅ Ownership Transfer — Buyers can transfer warranty ownership securely on-chain.
✅ Validity Check — Anyone can verify whether a warranty is active or expired.
✅ Revocation Control — Manufacturers can revoke invalid or fraudulent warranties.
✅ Event Logging — All actions (registration, transfer, checks) are recorded as events for transparency.
