• Web3.Js - Smart contract interaction
• Cypress - E2E Testing

👌 Contract Features

The core of Polychain is a Solidity smart contract that facilitates property ownership, transfer, pricing, and shared ownership. Here's a breakdown of its features:

• Property Creation

  • Owners can create properties by specifying the location and price.
  • Each property is represented by a unique token with an associated property ID.

• Property Transfer

  • Owners can transfer property ownership to another address.
  • Ownership transfers are securely facilitated using the ERC721 standard.

• Property Purchase

  • Users can purchase properties by sending the required funds to the contract.
  • The contract ensures that the purchase price matches the property's price.

• Property Price Update

  • Owners can update the price of their properties.
  • An event is emitted to notify interested parties about the price change.

• Shared Ownership

  • Owners can share ownership of a property with others.
  • Shared ownership is represented by assigning ownership shares to multiple addresses.
  • Owners can adjust the ownership shares of each participant.

• Ownership Percentage Calculation

  • A function calculates the ownership percentage of a specific address for a given property.
  • It takes into account the ownership shares assigned to that address.

• Nomination and Transfer of Shared Ownership (Future Enhancement)

  • A nomination feature can be added to facilitate the transfer of shared ownership to another address.

Contract Deployment and Usage

• To deploy the Property Smart Contract, compile and migrate it using the Truffle framework.
• The contract provides a secure and decentralized way to manage property ownership and transactions.
• Use the provided Ethereum wallet addresses and functions to interact with the contract.
• The contract enforces ownership transfer rules and manages shared ownership transparently.
