1. Decentralised Marketplace Solidity Smart Contract

Welcome to the Decentralised Marketplace project repository! This decentralized solana-based project from RiseIn's Solidity Fundamentals Course leverages the Solidity blockchain programming language to design, implement, and test a decentralised Marketplace smart contract for the Ethereum network. Market Authorities can verify sellers. Sellers can add and update items, as well as receive payments. Every participant; Market Authority, sellers and buyers can buy items.

Now updated in the Foundry framework.

1.1. Table of Contents

1.2. Overview

The Decentralised Marketplace Solidity smart contract provides an intuitive overview of the inner workings of a potential Marketplace dApp. You can think of it as a decentralised Facebook Marketplace on an Ethereum network. This project ensures transparency and trust in the local business or products in a controlled, yet free environment through the use of smart contracts. You'll find the presence of market authorities in the smart contract whose major purpose serves to verify a seller (any address submitted to become a seller on the platform) and remove a seller should the seller be in violation. The marketplace is to serve all items that can be listed for sale. Visitors / buyers can verify seller information linked with an item, view items from a specific seller,ake purchases. Sellers can also perform same functions as buyers.

1.3. Features

  • Owner and market authorities can add other market authorities
  • Market authorities can verify Sellers
  • Sellers can add & delete their listed items
  • Sellers can view and withdraw sales balances from contract
  • Buyers can retrieve seller and item information
  • Contract returns excess value sent by buyres during purchase

1.4. Smart Contracts

The Solidity smart contracts in this project facilitate the workings of the Decentralised Marketplace as described above. The unit tests tests the smart contract.
