A collaboration between the Blockchain Acceleration Foundation (BAF) and Arbitrum has established a procedure to scrutinize the development of decentralized applications that use Arbitrum technology. This project acts as a practical guide for the first Arbitrum Workshop session. The exercises were intended to provide practical knowledge regarding Ethereum’s upgradeability, smart contract creation, and real-time implementation of blockchain services. The whole activity is aimed at distributing cupcakes evenly.
The exercise indicates that the first step is to set up and position the cupcake machine. This is followed by positioning, which requires the project directory to be configured. The next step is to position the smart contract locally. The next step is to connect the smart contract to the local testnet.
Once completed, the smart contract must be placed on the Arbitrum Sepolia Testnet. To achieve this, the configuration of the Metamask for Arbitrum Sepolia is required. After this, the Hardhat configuration is updated and Testnet $ETH is obtained on L1 Sepolia. The next stage is to obtain $ASPL by bridging $ETH from L1 Sepolia to Arbitrum L2. At this point, the smart contract must be positioned, observed on a blockchain explorer, and subjected to testing with Metamask.
After successfully completing the authentication process and verifying the functionality of the smart contract on Arbitrum’s Sepolia testnet, the next step is to deploy it on Arbitrum One Mainnet. In these circumstances, payment of transaction fees in actual $ETH instead of $ASPL is mandatory.
Ultimately, a decentralized cupcake vending machine using Arbitrum emerged, demonstrating its usefulness in solving the problem of fair distribution. The most striking feature is that this application is linked to real-time situations and provides clarification. Blockchain technology and Arbitrum are necessary for the development of decentralized applications.
