GeoLogix Solutions transforms the logistics and delivery sector through cutting-edge GPS and blockchain technology, ensuring punctual deliveries in specified zones via an Ethereum-based dApp. The company pioneers efficiency, reliability, and transparency, utilizing a location-based smart contract to automatically reward drivers for adhering to geographic compliance. The system involves drivers’ smartphones transmitting GPS data to an Ethereum smart contract, processing cryptocurrency transactions as payment upon meeting contract conditions. In the event of non-compliance, the smart contract updates, affecting the driver’s internal rating, which is part of a system that penalizes deviations and rewards adherence with an incentive (in this case, transferring ether).
- Setup tool chains to build and deploy Ethereum based smart contracts
- Program in Solidity using Brownie or Hardhat
- Test and debug smart contracts
- Ethereum blockchain technology
- Hardhat compiler
- Sepolia testnet
- Alchemy blockchain node provider
Include a .env file with the following format if you want to deploy your own smart contract:
ALCHEMY_TESTNET_RPC_URL = "" PRIVATE_KEY = ""
Deploy the contract by running the following commands on your terminal:
> npm install > npx hardhat compile > npx hardhat run scripts/deploy.js --network sepolia
You can change the smart contract address for the web at the Admin.jsx and AddCheckpoint.jsx files and for the mobile app, at the smart_contract_repository.dart file. Make sure you've also copied the correct abi file and replaced it inside src/assets for the web app and assets/contracts for the mobile app.
For the web app, you can run the following command to start it:
> npm install > npm run dev
For the mobile app, first create a .env file with the following format:
ALCHEMY_TESTNET_RPC_URL = "" PRIVATE_KEY = "" ROUTE_API_KEY= ""
Then start the app by running the following command:
> flutter run
