In this tutorial, I will embark on an exciting journey of creating a decentralised art auction platform on the Celo blockchain. This platform aims to give artists and collectors a secure, transparent, and easy-to-use marketplace to buy and sell art as Non-Fungible Tokens (NFTs). The tutorial will provide a hands-on approach to leveraging blockchain technology for digital art commerce, with a focus on Celo’s unique features like its mobile-first approach and lightweight identity protocol.
Our primary programming language for this tutorial will be Solidity for writing smart contracts, which will be deployed on the Celo network. I’ll also use JavaScript along with Celo’s ContractKit library for building the backend of our Dapp. For the frontend, I’ll be using React, a popular JavaScript library, to create an interactive user interface.
Throughout this tutorial, you’ll learn:
- How to create and manage NFTs on Celo, including minting and transferring NFTs.
- How to create a smart contract for a decentralized auction, handling bidding, cancellation, and auction settlement.
- How to integrate Celo wallets, like Valora, for payment in stablecoins (e.g., Celo Dollar).
- How to use Celo’s ContractKit to interact with smart contracts.
- How to build an intuitive and mobile-friendly frontend to interact with the Celo blockchain.
By the end of this tutorial, developers will gain a comprehensive understanding of NFTs, how auctions work in the blockchain world, and more importantly, how to leverage Celo’s unique features to create an efficient, user-friendly Dapp. Additionally, developers will also gain practical experience in deploying a real-world application on a blockchain platform, thus solidifying their skills in blockchain development and smart contract programming.
Prerequisites for this tutorial include a basic understanding of blockchain technology, familiarity with JavaScript (and React), and some experience with Solidity.
