Architecture

• Frontend (UI/UX): use NextJS and Chakra UI framework.
• Offchain DB: use Mongo DB.
• Smart contract interaction: use EthersJS to send transactions.
• Wallet Connector: use Metamask API to connect wallet.

We use Solidity and Hardhat to develop smart contracts. For the front-end development, we use NextJS and EthersJS.

Prerequisites

To understand source code, you should have basic knowlege of:

• FON smart chain mainnet.
• Solidity
• Hardhat
• NodeJS
• React
• Next JS
• Wagmi
• Linux commands.

Installation steps

Step 1: Install Dev environment

• Install NodeJS (16+)
• Install VisualCode studio.
• Install Solidity & Hardhat addons for VisualCode.

Step 2: Install libraries

• Go to each folder
  • cd frontend -> npm i
  • cd contracts -> npm i

Step 3: Deploy smart contracts

Go to folder: cd contracts

• Deploy contracts:
  • Use: npx hardhat deploy-contract --network fsc --show-stack-traces
• Verify contracts:
  • Use: npx hardhat verify --network fsc {contract address}
• To test smart contracts
  • Use npx hardhat test.

Step 4: Setup .env

Setup ENV file in each folder: Frontend, Contracts.

• cp .env.example .env and change variable values.

Commands to start
