The Problem Lancy Parcel Solves

Lancy Parcel addresses major challenges in the logistics industry by ensuring secure, transparent and verifiable parcel tracking.

• Stolen or Missing Parcels: Every parcel’s journey is immutably recorded on the blockchain, preventing lost or stolen items from going unnoticed.
• Fake Signature Fraud: With cryptographic digital signatures, only verified employees and recipients can sign for parcels, eliminating unauthorized deliveries.
• Proof of Recipient & Seller Accountability: If a dispute arises (e.g., fake products or unreceived items), tamper-proof records provide legal proof, ensuring fraudulent sellers are held accountable.
• Mishandling & Damaged Parcels: Parcel conditions can be tracked at each hub and responsible employees are directly linked to each handover, reducing careless handling.

Lancy Parcel ensures that every transaction is secure, every signature is verified, and every parcel is delivered with accountability.

Requirements

Before you begin, you need to install the following tools:

• Node (>= v20.18.3)
• Yarn (v1 or v2+)
• Git

Quickstart

To get started with Scaffold-ETH 2, follow the steps below:

1. Install dependencies if it was skipped in CLI:

cd my-dapp-example
yarn install

2. Run a local network in the first terminal:

yarn chain

This command starts a local Ethereum network using Foundry. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in packages/foundry/foundry.toml.

3. On a second terminal, deploy the test contract:

yarn deploy

This command deploys a test smart contract to the local network. The contract is located in packages/foundry/contracts and can be modified to suit your needs. The yarn deploy command uses the deploy script located in packages/foundry/script to deploy the contract to the network. You can also customize the deploy script.

4. On a third terminal, start your NextJS app:

yarn start

Visit your app on: http://localhost:3000. You can interact with your smart contract using the Debug Contracts page. You can tweak the app config in packages/nextjs/scaffold.config.ts.

Run smart contract test with yarn foundry:test

• Edit your smart contracts in packages/foundry/contracts
• Edit your frontend homepage at packages/nextjs/app/page.tsx. For guidance on routing and configuring pages/layouts checkout the Next.js documentation.
• Edit your deployment scripts in packages/foundry/script
