Collecting user feedback is crucial for achieving product-market-fit and driving success in web3 applications. As the industry continues to evolve, it's essential to adopt innovative approaches that prioritize user experience (UX) design. One such approach is leveraging decentralized feedback forms to collect valuable insights from your app users.

In this tutorial, we'll explore the benefits of using on-chain feedback forms, why they're crucial for web3 dapp success, and provide a step-by-step guide on how to deploy and integrate these forms into your frontend.

Why Decentralized Feedback Forms Matter

Native, decentralized feedback forms are essential in web3 due to their numerous advantages. By deploying smart contracts on blockchain networks like Linea, you can:

  • Cut costs dramatically: The one-time cost of creating a form is during the deployment of a smart contract. If deployed on an L2 like Linea, the cost is usually not more than a few dollars.
  • Enjoy near-infinite customization possibilities: Design your form to collect any type of feedback (text, reactions, links, etc.). Customize your frontend as needed, as it's completely distinct from the contract.
  • Pay only for what you use: With decentralized forms, there are no payment tiers based on response volume. You can record as many responses as you want without incurring additional costs.

Creating Your Own Decentralized User Feedback Form

To get started, follow these steps:

Step 1: Install MetaMask

First, install the MetaMask browser extension to configure your wallet for Linea. This will allow you to deploy and interact with smart contracts on the network.

Step 2: Acquire LineaETH from a Faucet

Next, obtain some LineaETH by topping up your wallet using Infura's faucet. This will give you access to free 0.5 LineaETH daily.

Step 3: Acquire a Linea RPC Endpoint

Sign in to Infura and create a new project to generate an API key for your Linea testnet endpoint. Note this endpoint, as you'll need it later to deploy your Form-xChange contracts.

Step 4: Install Node and NPM

To install and use the required technologies (Infura, Next.js, Truffle, and Dapp API), you'll need node and npm on your local machine. Download and install both for your operating system.

Step 5: Clone the Form-xChange Repository

Clone the open-source Form-xChange repository from GitHub to access its source code. This will allow you to customize the feedback form to suit your needs.

Step 6: Deploy the Feedback Form

Finally, navigate to the Truffle project and smart contract folder within the Form-xChange repository. Here, you'll find the FeedbackForm and FeedbackFormFactory contracts. These contracts implement an individual form that stores questions and responses, as well as a factory contract for deploying customized versions.

By following these steps, you can integrate decentralized feedback forms into your web3 application, providing valuable insights from your users and driving app success.
