Canvassing - Participant: Online Surveys, Paid in Tokens

online surveys that reward participants for answering questions, built on Celo

What is Canvassing?

A Next.js-based Web3 application that bring surveys to participants (active Celo wallet addresses), and uses a smart contract to distribute rewards.

How It Works

1. Survey Booking

Participants perform an on-chain booking of a survey to secure their reward and do the survey at their own time.

2. Automated Rewarding

Once a Participant completes a survey (e.g. submits a form), an off-chain signature is created to help them claim from the smart contract.

3. Secure Smart Contract Transactions

ClosedSurveyV6.sol is a secure Solidity smart contract that manages value by ensuring only the right person gets a reward.

Getting Started

Prerequisites

• Node.js (Latest LTS version)
• npm or yarn

Quick Start

1. Clone and install:

git clone https://github.com/andrewkimjoseph/canvassing-participant
cd canvassing-participant
npm install  # or yarn install

2. Configure environment: Create .env file with the following:

NEXT_PUBLIC_AMPLITUDE_API_KEY=""
NEXT_PUBLIC_FIREBASE_MEASUREMENT_ID=""
NEXT_PUBLIC_FIREBASE_APP_ID=""
NEXT_PUBLIC_FIREBASE_MESSAGING_SENDER_ID=""
NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET=""
NEXT_PUBLIC_FIREBASE_PROJECT_ID=""
NEXT_PUBLIC_FIREBASE_AUTH_DOMAIN=""
NEXT_PUBLIC_FIREBASE_API_KEY=""
NEXT_PUBLIC_RPC_API_KEY=""
SENTRY_AUTH_TOKEN=""
NEXT_PUBLIC_REOWN_PROJECT_ID=""

Or copy the .env.example file

cp .env.example .env

3. Launch development server (front-end):

cd front-end
npm run dev  # or yarn dev
