As the Web3 paradigm shift reshapes the internet, developers must prioritize user engagement, democratized decision-making, and data-driven insights. Integrating a feedback form into your decentralized application (DApp) bridges the gap between users and developers, enabling real-time feedback at scale.
From DAOs using feedback forms for on-chain governance to businesses measuring employee sentiment, these tools are indispensable. This guide walks you through integrating a feedback form into your DApp using Form xChange, an open-source tool built with MetaMask SDK and Consensys technologies.
What Is Form xChange?
Form xChange is an open-source blockchain-based feedback form tool. Deployed on Linea (an EVM-compatible zkEVM rollup), it supports anonymous voting, transparent results, and cross-platform adaptability.
Key Features:
Smart Contracts:
FeedbackForm: Manages individual forms.FeedbackFormFactory: Deploys new form contracts.
Roles:
- Form Authors: Create forms, view aggregated scores.
- Participants: Submit anonymous feedback, access results.
How to Integrate a Feedback Form into Your DApp
Step 1: Clone the Form xChange Backend
Prerequisites: Node.js ≥v16, Truffle.
git clone [email protected]:Consensys/Form-XChange.git
cd Form-XChange/packages/form-XChange
truffle compile
truffle test Step 2: Deploy to Linea
